How Do I Add User Codes To A VISTA 20P, 21iP, 15P, 10P?
The procedure to add user codes to a Vista 20P, 21iP, 15P and 10P is the same, the difference is the number of user codes each control panel supports.
A master user code is the only code that can create secondary user codes.
Honeywell's factory default master code, which is user 02 on every panel mentioned above, is 1234. The master code can be changed by using the current master code or the installer code (Honeywell's factory default installer code is 4112). To change the master user code enter the existing 4 digit master code, followed by the numbers 8 0 2 plus the new 4 digit master code twice, i.e., [1234] + [8] + [02] + [4321] + [4321]. When you've successfully changed the user code, you will hear a short confirmation beep, letting you know the code has been updated. To use the Installer Code to change the Master Code, once you're outside programming, enter Installer Code+8+02+New 4 digit code, i.e., [4112] + [8] + [02] + [4321]. You will hear a brief confirmation beep once the code is changed.
In addition to the 4 digit user code, a user is assigned a 2 digit user number. The master code user number is 02, the installer code is user 01. Remembering the 2 digit user number is very important if you need to delete a user code.
To delete a secondary code, do the following: [Master Code] + [8] + [User Number] + [#] + [0]. You will receive a short confirmation beep letting you know the code has been deleted.
To add a secondary user code, enter the 4 digit master code followed by the number 8, plus the 2 digit user number (any number from 03 or higher) plus the 4 digit user code, i.e., [1234] + [8] + [03] + [5678]. The system will beep to confirm the user was added.
Each user code can be assigned an authority level. The authority level defines which system functions the user can or cannot do. The master code does not have an authority level. The available levels are as follows:
Level 0 = standard level, users can arm and disarm the system and bypass zones.
Level 1 = arm only - can arm the system but cannot disarm the system.
Level 2 = guest - can arm the system but can only disarm if the system was armed using this code.
Level 3 = duress code - when used the system will disarm normally but will send a silent signal to the central monitoring station informing them of a hostile situation and authorities will be contacted immediately,
Level 4 = Partition Master (Vista 20P, Vista 21iP only). A Partition Master has the same permissions as the System Master, but for their respective partition only. A Partition Master can change itself and any secondary code in its partition, but can not be used to change the System Master (User 02).
When creating a security code, you need to choose a 2 digit user number, a 4 digit user code, assign an authority level to that user, and determine any other attributes that should be assigned to it, such as assigning a keyfob to it.
To assign the authority level attribute - We will show assigning user 03 as a Guest Code (Authority Level 2.) Enter master code followed by the number 8, plus the 2 digit user number, the # sign plus 1 (attribute), plus the authority level, i.e., [1234] + [8] + [03] + [#] + [1] + [2]. You will get a short confirmation beep, letting you know the command has been successfully executed.
User numbers 03 and higher on the Vista 15P, and Vista 10P, and users 04 through 32, and 34 through 49 on the Vista 20P, and the Vista 21iP will automatically be assigned authority Level 0 = standard user, when created. See below for a list of all attributes that can be assigned to user codes.
The Vista 20P and 21iP support a total of 49 user codes.
The Vista 15P supports a total of 33 user codes.
The Vista 10P supports a total of 17 users codes.
The total number of user codes includes the master and installer codes.

An end user can only see the user codes on the system with Total Connect 2.0. If you are unsure what code is programmed to a user slot, you'll need to delete that user code and re-add it to be what you would like it to be.
I understand how to add or delete user codes. My problem is this: Ademco Vista 20p panel. Gave someone a user code, now I want to delete it. But I can't remember what "user number" I assigned to them. For example: 04, 05..ect. Anyone have a solution? Any way to list assigned user numbers?
Thanks Bryce, can anything be done to override this or am I looking at a whole new system?
It could be the fact that it is an ADT system and they probably have done a programming lockout preventing you from making changes to the system.
I have a Vista-10P from ADT, with WA10P-1.6 from 2005 PROM, with a 6160 Keypad, and no matter what I try, I'm unable to change the default ADT installer code. I'm able to get into programming, I enter the new code, but it never accepts it and just gives me a long beep each time. I was only able to change the Master code, but I also cannot program any user codes, I try various _TAG_ (04,05,06,07 etc) and none of them accept or make any sound after I enter in the new code. Could there be some type of system lockout because this is an ADT system that is preventing me from changing the installer code and adding additional users?
Ah yes, that means you switched it to a Partition 2 keypad and you must have had a cancelled alarm that had to be cleared on P2.
I figured it out, I accidentally changed the code for *189 and *190 from 2's to 1's...I imputed the correct numbers and that took care of the issue.
not sure if this helps but here are the few pages from the install guy with what he wrote in the manual... page 45 - 46
Here is what I see....
Try pressing Setup icon (Wrench and screw driver) and then Disp & Audio Setup icon and then your installer code and check if the EN50131 mode is enabled or disabled. If it's enabled, disable it and test again.
forgot the WA Prom.... it is WA20P - 9.18
I agree I should see something like this when after an alarm was triggered, however, this comes up without an alarm having been triggered and only setting the "away" button, and then returning to disarm the alarm. Before I changed the codes, I think I messed up the original programing by going into the console mode on the 6280 and then entering the (installer code) +(800), followed by (*) + (189) (1111) to enable any touchscreen keypads and ended it with (*)99 which programed all the keypads I guess and set something back to default maybe? Whatever I did, it now comes up for the master code as well so I must have changed the global setting for the "away" mode.
What is the 'WA' PROM number on your VISTA control panel? No matter what code you use when disarming after an alarm was triggered, you will see the Alarm Canceled message and need to disarm a second time to clear the "latched alarm" message. This is by design so that if you come home when the siren is going off and you disarm, you don't have to wonder which alarm had been activated. Also, if you disarm without an alarm having been triggered, no matter what code you use, you should not be seeing this message. Can you test another arm/disarm with user 3, without letting an alarm activation occur to see if you get this message?
Hi, I had three codes, the installer code, the master code, and one other that was set to user 03. I have deleted 03 code and created a new 03 code. Now, every time that I use the 03 code to disarm the system, a annoying "control panel message" screen pops up after the alarm turns off and the only way to remove the message is to input the code again and I would like to have this option/ screen pop up turned off. The master code doesn't have this screen pop after I input the disarm code, nor did the code that I deleted. Can anyone help solve this problem? I use the 6280 touch screens to program the Vista system. Please help!!

Flow-based enzymatic synthesis of melatonin and other high value tryptamine derivatives: a five-minute intensified process†
To increase the uptake of biocatalytic processes by industry, it is essential to demonstrate the reliability of enzyme-based methodologies directly applied to the production of high value products. Here, a unique, efficient, and sustainable enzymatic platform for the multi-gram synthesis of melatonin, projected to generate around 1.5 billion U.S. dollars worldwide by 2021, and its analogues was developed. The system exploits the covalent immobilization of MsAcT (transferase from Mycobacterium smegmatis) onto agarose beads increasing the robustness and longevity of the immobilized biocatalyst. The fully-automated process deriving from the integration between biocatalysis and flow chemistry is designed to maximize the overall yields (58–92%) and reduce reaction times (5 min), overcoming the limitation often associated with bioprocesses and bridging the gap between lab scale and industrial production.

in case of overflow, we can ask a separate thread to clear the buffer, meaning actual removal.
The libcds library has five URCU implementations. All of them live in the cds::urcu namespace:
 - general_instant is the implementation that follows the described URCU algorithm: each removal invokes synchronize, no buffering. If removal is a fairly frequent operation, i.e. the structure is not really "almost read-only", this implementation is rather slow.
 - general_buffered is the implementation with a general lock-free buffer of a predetermined size. Dmitry Vyukov's queue will be used as the lock-free buffer: cds::container::VyukovMPMCCycleQueue. Such implementation performance is comparable to Hazard Pointer.
 - general_threaded is similar to general_buffered; a dedicated thread performs buffer clearing. Such implementation is inferior to general_buffered due to additional synchronization with a dedicated thread. At the same time, it does not slow down writers.
 - signal_buffered is the analogy of general_buffered, but it is based on the signal-handled URCU; not for Windows systems.
 - signal_threaded is the analogy of general_threaded for the signal-handled URCU; not for Windows systems either.
A big number of URCU implementations raise the problem of writing container specializations for URCU. The thing is that the implementation of containers for the URCU scheme differs significantly from the implementation for the Hazard Pointer. Therefore, a separate specialization for URCU is required. I would like to have one specialization, rather than five.
To simplify the writing of specialization for URCU, the cds::urcu::gc wrapper class has been introduced:
template <typename RCUimpl> class gc; in which RCUimpl is one of URCU implementations: general_instant, general_buffered etc.
Using this wrapper, it will be no problem to write only one URCU specialization:
template <
 class RCU,
 typename Key,
 typename Value,
 class Traits
>
class SplitListMap< cds::urcu::gc< RCU >, Key, Value, Traits > ...
It should be noted that the main function of the URCU algorithm in libcds during removal is not synchronize, but retire_ptr. This function places the removable element in the URCU buffer and calls synchronize at the right time (for example, when the buffer is full). So it is not required to call synchronize explicitly, although it is acceptable. In addition, this solution unifies the URCU interface and the Hazard Pointer.
All of these URCU algorithms are implemented in a typical libcds manner: there is a global singleton object for each variable. Its initialization is performed by calling the constructor of the cds::urcu::gccds::urcu::general_buffered< > wrapper object at the beginning of main(), after calling cds::Initialize():
#include <cds/init.h> //cds::Initialize и cds::Terminate
#include <cds/gc/general_buffered.h> // general_buffered URCU
int main(int argc, char** argv)
{
 // Initialize libcds
 cds::Initialize() ;
 {
 // Initialize the general_buffered URCU singleton
 cds::urcu::gc<cds::urcu::general_buffered<> > gbRCU ;
 // If the main thread uses lock-free containers,
 // it should be attached
 // to the libcds infrastructure
 cds::threading::Manager::attachThread() ;
 // That's it, libcds is ready for use
 // Next is your code
 ...
 }
 // Terminate libcds
 cds::Terminate() ;
}
Just like for the Hazard Pointer scheme, each thread using URCU-containers should be initialized in a special way:
// cds::threading::Manager
#include <cds/threading/model.h>
int myThreadEntryPoint(void *)
{
 // attaché the thread to the infrastructure of libcds
 cds::threading::Manager::attachThread() ;
 // Now we can use lock-free containers of libcds
 // in this thread
 ...
 // Detach the thread from libcds
 cds::threading::Manager::detachThread() ;
 return 0;
}
Using URCU containers of the libcds library is simple: just declare a container object with the URCU gc, — and that's it. All the specifics of working with URCU is hidden inside the URCU specialization of the container. No external synchronization when accessing such container is required.
UPD: Oops! "_No external synchronization when accessing such container is required_" — I was wrong. Actually, some methods of some URCU containers do require prior entering a read-side critical section. As a rule, these are methods of removal (extraction) of a container element. URCU can provide the capability of returning a pointer to the element found by key. This capability is a rare exception in the world of lock-free, in which returning a pointer is deathlike, as the element can be removed any time by a concurrent thread. To work safely with the returned pointer to the element, we should be in the read-side critical section. So in this case, we should explicitly invoke access_lock, before calling the container method, and then access_unlock after finishing our work with the pointer. The exception-safe method is the scoped-lock use in a separate block of code.
The description of each method of the URCU container of the libcds library specifies the way to call this method – in a critical section or not.
If you decide to create your own container class based on the URCU implementation from libcds, you'd better know well the internal structure of the library's URCU containers. In principle, there's nothing too special about it: call gc::access_lock() when entering the method, and gc::access_unlock() when exiting it (gc is one of URCU implementations. For safe exceptions, you'd better use the scoped-lock techniques, instead of invoking functions). The only subtle point is element removal. The method of removal should also be in the read-side critical section, but physical removal, performed by calling gc::retire_ptr, should be carried out outside the read-side critical section. Otherwise, a deadlock is possible: inside, the gc::retire_ptr method can invoke synchronize.
Libcds defines URCU specializations for all set and map classes. URCU specializations for containers, such as «queue» and «stack» are not defined – they are not «almost read-only» containers, so URCU is not for them.
Lock-free Data Structures
Comments
 1. Interesting article! Here are a few comments:
 The following two comments apply to your introduction. Having no context on what you mean by «At first», I will assume that you are explaining the RCU technique as today's state of the art. Else we specific reference would be needed.
 «search synchronization is not really necessary– when there are no writers, readers can work in parallel»
 -> this is slightly misleading. In RCU, readers can progress in parallel with updates.
 «At some safe moment in time, when there are no readers, we can replace the data structure with the modified copy. As a result, all subsequent readers will see changes made by the writer.»
 -> This is inaccurate. In RCU, publcation of the modified copy is performed while there are readers actively accessing the old one. We then wait until no reader can still possibly see the old copy before reclaiming its memory.
 «it's quite easy to determine the safe moment in time for replacing data with the modified copy.»
 -> again, there appears to be confusion between publication and grace period guarantees.
 «As we know, having atomic operations, we don't have to make a copy of the data, but can change the data structure "on the fly" along with reading it.»
 -> In RCU, a copy of the old data is done into a new memory area. Publication of that memory area is performed by storing to a word-aligned pointer. The store is an atomic (indivisible) operation, but it's not what we would generally call an atomic operation in the sense of a LOCK prefix on Intel.
 «Then the «reader» becomes the thread that executes any operation, except removing the element from the data structure.»
 -> untrue. The writer thread(s) are responsible for both publication of new data, and for awaiting grace periods before reclaim.
 «The nThreadCtl most significant bit does not coincide with the g_nGlobalCtl most significant bit, which means that the reader entered the critical section after the grace period had started.»
 -> as you point out later in the article, the algorithm does 2 flip and wait. This matter of fact does not fit with the explanation given in the sentence

Objectives for recovery of alosines commonly involve improving fish passage at dams during migration. However, a quantitative basis for dam passage performance standards is largely absent. We describe development of a stochastic life-history-based simulation model for American shad, Alosa sapidissima, to estimate effects of dam passage and migratory delay on abundance, spatial distribution of spawning adults, and demographic structuring in space and time. We used the Penobscot River, Maine, USA, as a case study to examine sensitivity of modeled population metrics and probability of achieving specific management goals to inputs. Spawner abundance and percentage of repeat spawners were most sensitive to survival and migration delay at dams, marine survival, and temperature cues for migratory events. Recovery objectives related to abundance and spatial distribution of spawners were achievable under multiple scenarios, but high rates of upstream and downstream passage were necessary. The simulation indicated trade-offs between upstream and downstream passage efficacy whereby increased downstream passage was required to maintain or increase population abundance in conjunction with increased upstream passage. This model provides a quantitative support tool for managers to inform ecologically based decisions about a suite of management scenarios to facilitate recovery and sustainability of diadromous fish populations.

The blue racer, as its popular name implies, is an extremely fast snake that can reach speeds of over 7 kilometers per hour (4,3 miles per hour), which is still considerably faster than the lightning speed of the highly deadly black mamba. Because of their speed, they are better able to catch prey or escape being preyed upon. It takes the species between 15 and 20 years to reach maturity in the wild.

How fast do racer snakes move?
North American racers are slim and long-tailed, with large eyes and smooth scales, and they are found only in North America. Some measure 1.8 metres (about 6 feet) in length. They are most active during the day and are among the quickest snakes on the planet, traveling at a pace of around 5.6 kilometers (3.5 miles) per hour on the ground and through vegetation.
Is a blue racer poisonous?
Is the blue racer snake a threat to humans' safety? These magnificent creatures are completely harmless and should be left alone. They are not venomous nor toxic, as is commonly believed, contrary to popular belief.
How many blue racer snakes are left?
The Blue Racer is now exclusively found on Pelee Island, which is located in western Lake Erie, in the province of Ontario. The number of adult Blue Racers on Pelee Island appears to have dropped since 1995, when there were around 205 of them. The Blue Racers of Ontario cover a large territory – the average for females is 111 hectares and for males it is 201 hectares on average.
How big is a blue racer snake?
Facts about the Blue Racer: What Is That Snake? – OPLIN – Adult body length ranges from 36 to 60 inches, with a record of 72 inches. When fully grown, they can reach lengths of 8 to 13 inches. Small animals, birds, frogs, lizards, other snakes, and huge insects are among the typical prey.
What snake kills the fastest?
The mamba (black mamba) The fastest snake on the planet is also one of the deadliest, as evidenced by its deadly venom. With its bite, the black mamba (Dendroaspis polylepis) may kill a human in less than 30 minutes, despite its ability to travel at speeds of up to 12.5 miles per hour (5.5 meters per second).
How fast is a water moccasin?
When it comes to speed, a cottonmouth snake can travel at an astonishing 2.42 meters per second.
Can I own a blue racer?
Because blue racer snakes are classified endangered in some regions of North America, it is difficult to find them for sale in the wild. They are not frequently encountered in the pet trade.
Are Blue Racers fast?
When they detect an incoming threat, blue racers are known to vibrate their tails, causing a buzzing sound to be produced, which alerts other snakes to the impending danger. They are exceedingly speedy and are well-known for their agility and quickness. The population of this species has seen a fast drop over a period of time.
Are racer snakes good pets?
Racers, in contrast to certain other kinds of snakes, are not suitable as pets. Despite the fact that they are quite placid creatures, they rarely develop accustomed to being handled. Due to the fact that these snakes are accustomed to moving large distances, they do not perform well in tiny environments.
How much does a blue racer weigh?
According to the subspecies, adult eastern racers may range in total length (including tail) from 50 to 152 cm (20 to 60 in) depending on their size, however a record-sized specimen was 185.4 cm (73.0 in) in total length. A normal adult specimen will weigh approximately 556 g (1.226 lb), with minimal difference in size between the sexes. A typical juvenile specimen will weigh around 556 g (1.226 lb).
How much is a blue green tree python?
Meet the snake with the highest price tag in the planet. In addition to being incredibly rare, blue green tree pythons are the world's most expensive snake, with a retail price of RM1. 8 million! In most cases, the snake is clothed in blue or blue-green scales with silver eyes, and it may be found in the Indonesian islands, in Australia, or in New Guinea.
What are the predators of the blue racer snake?
Probable natural predators of adult blue racers include raptors (such as the red-tailed hawk, Northern harrier, and Great Horned Owl), as well as carnivorous animals such as raccoons, coyotes, and foxes (as well as humans). Dogs and feral house cats have been observed killing and/or harassing juvenile blue racers in the past.
What is the fastest snake in North America?
09.22.2005 – The 22nd of September is a national holiday in the United States. The Eastern Coachwhip is the fastest snake in the United States of America, and it can reach speeds of up to 50 miles per hour. According to the manufacturer, it has a peak land speed of around 10 miles per hour and a top air speed of 190 miles per hour, similar to most aerodynamic objects achieving terminal velocity. Although ten miles per hour may not appear to be very quick, it is.
Are Blue Racers territorial?
Reproduction. In general, the mating season for blue racers occurs during the months of April and May, depending on the individual. During this period, the snake not only gets hostile, but it also becomes territorial. One can frequently observe two male blue racers engaged in battle over a territory or a female blue racer engaged in combat over a territory.

Yes, it qualifies the wind, you can read the sentence as: "The wind rises, it is electric."
It is meaning number 3 of the wiktionary definition of electric :
Being emotionally thrilling; electrifying.
Saying that the wind is electric is a way of qualifying the emotions the wind at this particular moment produces on people: it electrifies them, makes them maybe agitated, maybe thrilled, excited...

of those scenarios below and how to reproduce them in Node-Red.
Delay an Action
Most timers are used to delay a specific action until a relative later point in time (i.e. turning off a light after a specific time interval). Node-Red has a Delay node for performing this same time of set time delay.
Block Other Actions During a Defined Time Period
Many times in Openhab when you don't want an action occurring within a certain time frame of a previous action, you do so by setting a timer in the first action and then checking if a timer is still active when a second action tries to occur. In Node-Red there are a couple of different ways to accomplish this depending on some of the nuances involved. One is to use a "Rate Limit" within a delay and telling the delay to drop any messages that come in during the delay.
You can also use the Trigger node in Node-Red. These nodes are very flexible, allowing you to send actions at the start of a time period or at the end or during both. You can also extend the triggers if certain events happen. So for example if you have a motion sensor trigger a light on and then want it to turn off after the last trigger from your motion sensor you could use a trigger as follows:
As you'll see, there are many different ways with Delays and Triggers that you can approach solving the same problem.
Logging
Logging is one of the big strengths of Node-Red. You can create immediate Debug outputs that you can see from the edit window or to File nodes to write entries to an external log file.
Notifications
While Node-RED has some addon Nodes to help support different types of notifications, I wanted to still be able to leverage some of the built in functionality of OpenHAB as well. This required setting up necessary OpenHAB items and rules to interfact into OpenHAB's functionality.
Broadcast Notifications
Through the OpenHAB Cloud Connector _URL_ you are able to use the mobile apps to both access your system and receive broadcast notifications _URL_ To integrate this into Node-RED requires an item to carry the notification information and a rule to trigger the notification.
Item Definition:
String vNotification "Notification [%s]"'
Notifications.rules:
rule "Send Notification"
when
 Item vNotification received update
then
 sendBroadcastNotification(vNotification.state.toString)
end
And finally a Node-RED flow to send the notification. Here I used a change node to create my text message:
image
image
You can also use the template node to include other payloads or topics into your notification message:
image
image
If you want to add a time stamp to your message I was able to put together the following to create a plain language time stamp (i.e. 3:32 pm)
For cut-and-paste purposes:
msg.payload = msg.payload + new Date().toLocaleTimeString('en-US',{timeZoneName: 'short'});
return msg;
Audio & Voice
OpenHAB has the ability to play audio files and convert text-to-speech: _URL_ To take advantage of this integration we follow a similar approach as we did for the Broadcast Notifications above using a combination of a custom item and a rule combined with a Node-RED flow.
First to trigger a text-to-voice (assuming you have already setup everything in OpenHAB as per above).
Item Definition:
String vSpeech
Speech.rules:
rule "Send Speech"
when
Item vSpeech received update
then
say(vSpeech.state.toString)
end
And finally a NodeRed flow to tie it together.
image
I went a step further with mine to control the volume levels during and after sending speech (turning it up while the speech is broadcast and turning it back down). So I created a sub-flow (_URL_
image
image
Similarly for sending an Audio file saved to your conf/sounds directory:
Item Definition:
String vSound
Sound.rules:
rule "Send Sound"
when
 Item vSound received update
then
 playSound(vSound.state.toString)
end
And Node-RED flow:
image
image
Email
For email you can choose to use the SendMail binding _URL_ or alternatively you can do it directly from Node-RED using the email node _URL_ The one trick I did apply here is I didn't want to configure each node instance with my smtp server information and I wanted the ability to turn on and off the ability to send email (so I didn't spam my wife when I was testing) so instead created an email subflow and a control flow.
Email Subflow:

Looks very interesting. Does Node-RED support turning flows into nodes that can be displayed in the side bar? A related question is whether a flow can be parameterized and reused by instantiating a flow with specific parameters. For example, if I have a complex flow for a type of device and I have 20 of those devices, can I create a flow component that can be reused for each device by just specifying the device-specific parameters for each device?
(Rgerrans) #3
I haven't played with them yet but Node-RED has the concept of sub-flows which are reusable flows that are treated like a node in your main flows - _URL_
(Eurico Borges) #4
You should put this info in the Wiki. not just in the forum.
(Rgerrans) #5
Which Wiki?
(Eurico Borges) #6
I was thinking on _URL_
( ) #7
Hey @rgerrans, great to see this thread after just a few days!! :wink:
@eurico_borges I'd prefer the tutorials to stay in the "Tutorials & Examples" section. This way people can discuss solutions and related problems as well as post related solutions or alternatives. The article can also be modified and updated more easily here.
However, I'd be happy to include the tutorial in the list of recommended tutorials in the second half of: _URL_
(steve1) #8
Maybe I missed something, but BigTimer doesn't seem to completely replace cron triggers since the time specifications are at the minute resolution. For higher resolution triggers (e.g., every 15 seconds) there is a cron node in Node-RED.
(Joe Lawrence) #9
Can the two rule engines co-exist??? IE Can I use both?
(Rgerrans) #10
Good catch. BigTimer looks to me to be more of an on/off timer (with minute heart beat which I find useful for resetting my schedule status following a restart). It doesn't look like it's designed to do repeat triggers. That's one nice thing about Node-RED is all the different contributed nodes.
In addition to the cron nodes, you could also just put a loop with a timed delay in your flow to cause a repeat during your on window. Like this:
Edit: Just realized this approach won't turn off. There should be a way with a trigger instead of a delay to inject an off into the flow, Will have to play with it later,
(Rgerrans) #11
Yes. I'm running mine in parallel while I transition my rules over.
In addition, I created an OH rule/virtual text item last night to be able to do a sendBroadcastNottification going forward so that I can still send notifications to the OH Mobile App once i migrate all my rules to node-RED so I anticipate still using the OH rules for at least that (I'll add it to the tutorial when I get a gap of free time).
(Joe Lawrence) #12
Thanks, you're doing exactly what I was looking to do. Always good to have extra tools!!
(Rgerrans) #13
Ok, got a chance to play some more and went with a trigger so that I could use the off from BigTimer to stop the trigger. Needed to add a slight delay otherwise it would get ahead of itself

Nanobind extracted DNA is optimized for HiFi sequencing. Our kits provide you with an all-in-one extraction experience that can be used with a wide range of sample types. The PanDNA kit supports manual high-quality extraction from cultured cells, bacteria, whole blood, tissue, plant nuclei, and insect samples in 1 to 2.5 hours. The Nanobind HT CBB kit enables automation of DNA extraction for human and animal blood, mammalian cells, and bacteria. Our HT kit is compatible with up to four robotic platforms and 96 samples that can be extracted in 2.5 hours.
How does it work?
Nanobind kits contain specific reagents to process and lysate diverse sample types. Following lysis, the DNA binds to Nanobind disks which shield bound DNA from damage during extraction, resulting in HMW DNA. A final Short Read Eliminator (SRE) size selection step helps remove DNA fragments below 10 kb.
PacBio Nanobind HT kits enable automation of DNA extraction, the first step of an end-to-end workflow that harnesses the power of HiFi sequencing. Nanobind HT kits are designed for whole human blood and mammalian cell samples and are compatible with four robotic platforms.
SHORT READ ELIMINATOR (SRE) KITS
Simple size selection for optimal HiFi result
SRE treatment following DNA extraction helps removing DNA molecules below 10 kB. It results in improved HiFi read length distribution and HiFi sequencing yield. The SRE workflow is fast, easy, and inexpensive using simple size selective precipitation. HMW DNA is precipitated by centrifugation and low molecular weight (LMW) DNA is washed away. Many samples can be process in parallel in 2 hours (10 min hands-on time). HT solution will be available soon.
Procedure + checklist
This procedure describes the workflow for DNA size selection to remove molecules <10 kb using the SRE kit on HMW DNA before shearing and library preparation. The SRE kit is used for rapid size selection of unsheared HMW DNA samples. This method can significantly enhance mean read length by progressively depleting short DNA up to 10 kb.

by Bi, then we have this formula:
Importance(Pi)= sum( Importance(Pj)/Lj ) for all links from Pi to Bi
The ranks are placed in a matrix called hyperlink matrix: H[i,j]
A row in this matrix is either 0, or 1/Lj if there is a link from Pi to Bi. Another property of this matrix is that if we sum all rows in a column we get 1.
Now we need multiply this matrix by an Eigen vector, named I (with eigen value 1) such that:
I = H*I
Now we start iterating: IH, IIH, IIIH .... I^k *H until the solution converges. ie we get pretty much the same numbers in the matrix in step k and k+1.
Now whatever is left in the I vector is the importance of each page.

As for solving the duplicate issue in your interview question, do a checksum on the entire page and use either that or a bash of the checksum as your key in a map to keep track of visited pages.

Depends on how deep their question was intended to be. If they were just trying to avoid following the same links back and forth, then hashing the URL's would be sufficient.
What about content that has literally thousands of URL's that lead to the same content? Like a QueryString parameter that doesn't affect anything, but can have an infinite number of iterations. I suppose you could hash the contents of the page as well and compare URL's to see if they are similar to catch content that is identified by multiple URL's. See for example, Bot Traps mentioned in @Lirik's post.

 - This takes me to another question I have had. How do we hash whole content of a page. such pages are say at least 2 pagers. What kind of hash functions are able to hash 2 pagers to a single value? What is the size of a typically such hash output?

You'd have to have some sort of hash table to store the results in, you'd just have to check it before each page load.

The problem here is not to crawl duplicated URLS, wich is resolved by a index using a hash obtained from urls. The problem is to crawl DUPLICATED CONTENT. Each url of a "Crawler Trap" is different (year, day, SessionID...).
There is not a "perfect" solution... but you can use some of this strategies:
- Keep a field of wich level the url is inside the website. For each cicle of getting urls from a page, increase the level. It will be like a tree. You can stop to crawl at certain level, like 10 (i think google use this).
- You can try to create a kind of HASH wich can be compared to find similar documents, since you cant compare with each document in your database. There are SimHash from google, but i could not find any implementation to use. Then i've created my own. My hash count low and high frequency characters inside the html code and generate a 20bytes hash, wich is compared with a small cache of last crawled pages inside a AVLTree with an NearNeighbors search with some tolerance (about 2). You cant use any reference to characters locations in this hash. After "recognize" the trap, you can record the url pattern of the duplicate content and start to ignore pages with that too.
- Like google, you can create a ranking to each website and "trust" more in one than others.

The web crawler is a computer program which used to collect/crawling following key values(HREF links, Image links, Meta Data .etc) from given website URL. It is designed like intelligent to follow different HREF links which are already fetched from the previous URL, so in this way, Crawler can jump from one website to other websites. Usually, it called as a Web spider or Web Bot. This mechanism always acts as a backbone of the Web search engine.

Geography students discover the healing power of art
September 15, 2020
By Pam Lim
From natural disasters and food shortages to systemic racism and legal inequities, geography students tackle some of our most pressing global challenges. But seeking solutions and grappling with complex issues can take its toll on a student's mental health.
"Students are inundated with dire facts about the state of our planet," says SFU geography instructor Sharla Stolhandske. "In classrooms, we talk about these huge issues, but we don't address the effect it takes on our mental health."
So last semester, in an unconventional departure from traditional geography tools such as mathematics and theories, Stolhandske asked students to create drawings, paintings, poetry or music to express their ideas for how to make sense of our changing world. She wanted them to discover that art could not only help them engage on topics in a different way, but could also improve how they manage their mental and emotional well-being.
"Mental wellness is a hard conversation to have," says Stolhandske. "On top of that, across all disciplines, but especially science, creativity is not something we focus on as a learning outcome."
Stolhandske says the assignment generated apprehension as students wrestled with the switch from numbers and theories to creativity and vulnerability. But by the end of the semester, they gave overwhelmingly positive feedback on the art assignment. They had discovered the value of flexing a different muscle, and they went above and beyond in demonstrating their understanding of course materials.
"Academics are important to so many students," says Stolhandske. "Some feel like there's little room for error. Add a global pandemic to the mix and it can become very challenging.
"Art offers a way to connect, to express ourselves and to process complex feelings in ways that move beyond traditional methods."

The US Government operates several programs that influence the prices of agricultural products. The US government through the use of tariffs, subsidies and acreage control programs can strongly influence the supply and pricing for certain commodities. When the government levies a tariff on imported commodities it will make those commodities coming from other countries less competitive and as a result will increase demand for the domestically grown products. This should have a stimulative effect on prices for the commodity. Should the government lower the tariff on a given commodity foreign growers may flood the market with the commodity and drive prices down. Governmental subsidies tend to set a minimum price for the given commodity. These subsidies are designed to help ensure that the producers of the commodities can sell the commodity in the market at price the is higher than the cost to grow the commodity.
Applying "Government Agricultural Programs" to Securities Exams:
Acreage control programs are designed to limit the amount of the commodity that will be grown each year and therefore limit supply. The reduced supply will generally tend to provide support to the price of the commodity in the in the market. The Government through the use of acreage control programs pay farmers not to produce the commodity on some or all of their available farm land. The US Department of Agriculture operates The Commodity Credit Corporation or CCC to provide financing to farmers who grow and produce many of the commodities we use every day. Farmers may pledge their harvested and stored crops as collateral for loans. The CCC provides farmers with loans that may be renewed annually for terms of up to three years. The sole collateral for the loans are the stored commodities. Should the farmer default on the loan the CCC has no recourse other than taking possession of the pledged commodity. Liquidation of the commodities by the CCC is strictly regulated. The CCC may not sell the commodity in the open market in any way that would compete with domestic commodity producers. The CCC may only liquidate the forfeited commodity if the commodity is in immediate danger of spoiling. These are just some of the concepts you will need to master to pass the series 3 exam. Commodities futures pricing is a heavily tested concept on the series 3 exam and these programs are just some of the factors that influence prices.


System Administration Guide, Volume 1
Volume Management Provides Access to CDs
The arrangement for CDs is similar, except that the block and raw directories are labelled /dsk and /rdsk, respectively, and the CD-ROM device is actually located one directory beneath them.
In the illustration above, the additional directory is named c0t6. That simply reflects a particular system's device naming conventions. The directory name on your system could be different, though it would have the same format.
The CDs themselves, however, follow a convention similar to diskettes, in that they are mounted beneath the directory belonging to their device:
As a result of this arrangement, a system with one diskette drive and one CD-ROM drive would have the following /vol/dev file system:
(Actually, /vol/dev includes an additional subdirectory named aliases, but that is described later in this section.)


Square wave controllers produce trapezoidal waves, which are rather juggled, not smooth. The transitions between each square wave cause harmonic losses (loss of energy through sound in square wave controllers), making them less efficient. These controllers also have minimal computational power needs, requiring only the 3 phase on/off signal to drive the motor in a time sequence.
Compared to sinewave controllers, square wave controllers are generally cheaper due to minimal computational power needs.
Properties of Square Waves
A square wave is best described as a non-sinusoidal periodic waveform where the amplitude alternates at a steady frequency between fixed maximum and minimum values. The time between the minimum and maximum durations is almost similar. In a perfect square waveform, the maximum and minimum transitions are instantaneous. However, a perfect square wave is practically impossible to create, considering that the falling and rising edges are never instantaneous, plus the tops are never flat. A practical square wave(trapezoidal wave) usually has a non-zero rise time, and the tops are rarely flat.
Unlike sine waves with a smooth ascending and descending waveform with rounded edges at the negative and positive peaks, square waves have pretty steep, almost vertical negative and positive peaks. The top and bottom of the waveforms are usually flat, producing a waveform that matches its description, i.e., square.
Some properties of square waveforms include:
 - Square waveforms have instantaneous transitions between the negative and positive peaks. But this is rarely achieved in practice owing to the physical limitations of the controllers. The rise time and fall time refer to the period taken for the system to rise from the high peak and low peak, respectively.
 - In some cases, square waveforms never reach the theoretical low and high level, usually due to system overdamping or under damping. It will only oscillate about the high and low levels before settling into an intermediate level.
 - The positive portion equals the negative amount in one cycle (one up and down portion). The cycle repeats itself dozens of times, corresponding to the transmitted signal.
Benefits and Downside of Square Wave Electric Scooter Controllers
The most significant benefit of electric scooter controllers is that they are more affordable than sine wave e-scooter controllers and are compatible with different motors, including geared and gearless motors. What's more, they offer more efficiency in times of sudden acceleration and braking. However, square wave electric scooter controllers produce a great deal of noise when in operation and offer punchy, nonlinear control.
Pros of Square Wave Electric Scooter Controllers
 - Square wave electric scooter controllers are more affordable compared to their counterparts (sine wave e-scooter controllers) thanks to their minimal computational power need.
 - There's no need to undertake motor matching or tuning with a square wave controller since they are compatible with a wide range of motors, including geared and gearless motors.
 - Square wave controllers produce more torque than their counterparts, creating a punchy acceleration.
 - Square wave controllers are great performers in braking and sudden acceleration.
Cons of Square Wave Electric Scooter Controllers
 - Unlike their counterparts, square wave controller motors produce louder noise and heat, especially at average speeds. This makes them less efficient.
 - These controllers deliver nonlinear punchy acceleration. The overall acceleration of the scooter may be jerky, compromising the overall comfort.
 - Square wave controllers have lower efficiency in handling heavy loads and climbing steep roads.
 - With squarewave controllers, a voltage surge at high speed or acceleration may result in overheating and, even worse, damage to the vital components in the scooter, causing its complete shutdown.
Sinewave vs Squarewave controllers
Various analogies better describe the differences between a sine wave and a square wave controller. One common analogy is pushing a wheelbarrow down a path. A sine wave controller uses a smooth constant push the entire journey, while a square wave controller employs constant nudging or jabbing instead of a continuous, even push.
Another analogy to describe the difference between the two controllers is riding a bike with different wheel shapes. With a sinewave controller, it's like riding a bike with round wheels. On the other hand, a square wave appears like riding a bike having octagonal or square wheels. While both bikes will get you to your destination, you'll be more comfortable riding round wheels. Besides, the round-wheeled bicycle will get to your destination much faster compared to the other bike, which will be wasting energy.
Regarding efficiency, sine wave controllers offer better efficiency with reduced heat thanks to reduced harmonic content. Suppose you ride a scooter and feel the acceleration is a bit jerky instead of smooth. In that case, it's because of high harmonic content in the waveforms causing jerky acceleration with much noise. Sine wave controllers offer silky smooth torque since less energy goes into waste doing unnecessary tasks such as resonating the stator from harmonic content.
Square wave controllers are highly efficient in high-speed riding thanks to their high torque, which offers a punchy ride. However, for optimal performance, the controllers should be combined with a higher battery capacity and higher discharge to accommodate the high voltage drop.
Besides the output waveforms, the difference between square wave controllers and sine wave controllers also lies in the timing of the signals. Sine wave controllers have better timing than their counterparts hence have outstanding efficiency with smooth torque.
Advantages of a Sine Wave controller over a Square Wave controller
 Sine wave controllers have several advantages over squarewave controllers; the reason they are highly preferred these days. Some key benefits of these controllers over square wave controllers include:
 - During heavy load climbing, e-scooters with square wave controllers experience a significant reduction in performance. This is unlike e-scooters fitted with sine wave controllers, which still manage constant speed in steep climbs with 8-10% larger torque than a square wave.
 - In addition to the continuous speed travel in normal riding conditions, sine wave controllers offer much better riding comfort than their counterparts. This is primarily attributed to the smooth torque and low harmonic content loss.
 - Sine wave controllers generate lower noise and heat as compared to their counterparts. This comes in handy in enhancing the overall ride comfort.
 - Sine wave controllers offer a more extended range (miles per charge) than squarewave controllers. Square wave controllers consume a lot of current to achieve a constant speed, shortening the continuous mileage. An e-scooter fitted with a sine wave controller offers a 5-10 kilometres longer range compared to their counterparts. Of course, the range is dependent on other factors such as the scooter's make, battery capacity, riding conditions, and much more.
 - Sine wave controllers can increase field weakening speed by up to 20% without a consequent drop in torque. They are ideal for e-scooters demanding ample torque coupled with high speed. In squarewave controllers, the torque decreases with increased riding speed. In simple terms, when riding under the same torque and speed, a sine wave controller is stronger and faster than a square wave controller.
 - Sine wave controllers achieve outstanding efficiency regarding motor operation. This is due to several tweaks offered by the controller, including maximum torque control, which reduces the corresponding input current. These controllers also offer excellent demagnetization protection, which comes in handy to reduce the iron loss in the motor and ultimately increase the motor's life. Square wave controllers don't achieve this benefit.
 - Due to low harmonic failures, sine wave controllers offer the highest possible continuous torque and power. Square wave controllers lose a great deal of energy to sound, i.e. harmonic losses making them less efficient.
 - Square wave controllers are susceptible to overheating, especially at high riding speed or faster acceleration. This is primarily attributed to voltage sag, where the RMS voltage is reduced by 10-90% of nominal voltage for one-half cycle to one minute. In severe cases, a voltage sag may lead to a short circuit or complete malfunctioning of the motor. You may need to replace the entire motor drive, amounting to unprecedented expenses in such cases.
Verdict

When buying an e-scooter or if you're looking to fix your e-scooter controller, you'll need to choose between a sine wave and a square wave controller. As with any product, expect both controllers to have their fair share of benefits and downsides. While sine wave controllers are a bit pricey and need tuning to be compatible with a particular motor, they offer smoother acceleration, comfortable rides due to lower noise and heat generation, smoother speed control, and longer ranges.
Square wave controllers are cheaper and compatible with a wide range of geared and gearless motors. However, they have several downsides, including: produce more noises and heat generation due to high harmonic content loss, being susceptible to voltage sag at high speeds, less comfortable due to the nonlinear punchy acceleration, lower ranges, and reduced performance in stiff climbs or when carrying heavy loads.
So, which controller should you choose? While the decision lies solely with your specific needs and preferences, sine wave controllers are highly recommended. With the lowest harmonic current content loss, smooth torque, and acceleration coupled with a more extended range and outstanding ride comfort, sine wave controllers are evidently better than their counterparts.

Here's how your plants will look on arrival. All plants are dormant with no leaves or foliage.
Regal Privet Plant - Ligustrum obtusifolium var. regelianum
The Regal Privet Plant is considered a fast-growing, hardy shrub. If left to grow on its own, it will create spreading branches that can mature into a beautiful, found-like hedge. This formation is what makes it so attractive as a backdrop to a garden in landscaping. It is capable of growing to hide things like foundations or walkway edges. The Regal Privet Plant has a wide range of zones, growing best in zones 3 to 7. It grows at a moderate rate in full sun to partial shade. It reaches a height of about 10 to 12 feet while spreading at approximately the same distances. One attractive quality about the Regal Privet is its excellent adaptability to some soil types. It prefers moist, well-drained soils that see a relative amount of sun when in a humid, southern environment, but it is also a hardy deciduous hedge when growing in more northern climates.
The Regal Privet Plant's upright growth is marked by green foliage and white flowers that bloom in the spring. It carries dark berries through the winter and is both adaptable and unable as a landscaping plant. Its dense foliage is what makes it so attractive for use in backdrops, but its berries are also appealing to some birds and wildlife who come to eat from them in the winter. The plants grow upright in oval to radiation rounded formations, then achieve an arching vase growth as they mature. If frequently pruned, these plants will form a hedge shape. The dark green leaves are semi-evergreen in the south and slowly deciduous in the north, growing opposite in elliptical to oblong shapes of 1" to 1.5" of length. The blossoms appear in May and June and appeal to some bees. The growth rate of Regal Privets depends on the frequency of pruning. The plants are useful in urban areas as they adapt well to stress.

Malabar neem (Melia dubia Cav.), commonly called as Hebbuvu or Dreak or Gora Neem, is a dry deciduous multipurpose tree belongs to the family Meliaceae. It is an indigenous and multipurpose fast growing tree species, which has a great potential as a plantation species to meet the raw material requirement of the various wood-based industries. The present study was conducted at Zonal Agricultural and Horticultural Research Station, Hiriyur to assess the growth performance of Melia dubia planted at a spacing of 4 m × 1 m, 4 m × 2 m and 4 m × 3 m in sole condition without intercrop and with integrating horse gram as intercrop. The experiment was laid out in Randomized Complete Block Design (RCBD) with six treatments and four replications. Tree parameters viz., tree height, diameter at breast height (DBH) and crown diameter were recorded and basal area and volume of trees were calculated before sowing as initial readings and after harvest of horse gram as final readings. The study revealed that performance of Melia dubia with and without horse gram intercrop was on par and relatively higher in intercropped condition. It was also evident from the present investigation that higher performance of M. dubia was recorded under wider spacing of 4 m × 3 m followed by spacing of 4 m × 2 m and least performance was found in the spacing of 4 m × 1 m. In the present study 4 m × 3 m spacing might be most suitable for taking up M. dubia based agroforestry in the central dry zone of Karnataka.

･ A shipping ceremony was held at the Composite Wing Center of the Nagoya Aerospace Systems Works on February 10th.
･ Digital technology and Artificial Intelligence (AI) integrations have helped MHI expand and improve productivity
Tokyo, February 10, 2020 - Mitsubishi Heavy Industries, Ltd. (MHI) has shipped its 1000th composite-material wing box for the Boeing 787 Dreamliner. This key milestone comes roughly thirteen years after the first unit was shipped in May, 2007. The latest batch of wing boxes has been shipped from the Higashinagoyako Pier, adjacent to the factory and Central Japan International Airport. They will then be transported by the Dreamlifter to Boeing's factory in South Carolina (North Charleston, South Carolina) on February 12, 2020.
On the day of the shipment, a ceremony was held to commemorate the event. Many people, including Mr. Will Shaffer, President of Boeing Japan, attended the ceremony and congratulated the accomplishment.
The composite-material wing boxes of the 787 are made of carbon fiber reinforced plastic (CFRP), a material never used before for the wing box of a commercial airplane. The material and production method applied is superior in strength, rigidity, and corrosion resistance to conventional aluminum alloys and titanium alloys, resulting in a significant weight reduction and more than 20% improvement in fuel economy compared to conventional models.
Since the beginning of the 787 program, MHI has incrementally incorporated innovations such as AI (artificial intelligence), digital technology, and other technologies to improve quality, expand production, and reduce costs.

Zippy the Fanbot

This instructable was created in fulfillment of the project requirement of the MAKEcourse at the University of South Florida (_URL_).
Zippy the Fanbot is an Arduino based project which utilizes thrust produced by propellers mounted on brushless motors in order to propel or rotate the bot in desired directions. The user controls the bot with an infrared remote control. The name Zippy was coined from the fact that the majority of the assembly is held together with zip ties.
Teacher Notes
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: 3-D Print the Parts
The frame of this assembly as well as the Arduino case and electronics box were 3-D printed. Each part was printed at 30% infill with 3-5 shells. I have uploaded the STL part files to make it easy for you. Just download them and bring them to a good 3-D printer!
Step 2: Purchase the Necessary Electronics and Parts
A number of electronics and parts will be needed in order to build and use Zippy the Fanbot. Here is a list of all the parts that I used in the making of this project:
1x Arduino Uno R3
1x VS/HX1838B Infrared Sensor
1x Pack of Male to Male Header Pins (Enough for Arduino Pins)
1x Pack of 8" Female to Female Jumper Wires
1x 3S 11.1V Lithium Polymer Battery
1x Power Distribution Harness or Power Distribution Board
4x Afro SimonK 20A OPTO ESCs
4x Sunnysky X2212 KV980 Brushless Motors
2x APC CW 8045 Multirotor Propellers
2x APC CCW 8045 Multirotor Propellers
1x Pack of 4" Zip Ties
4x Light Duty Swivel Casters
1x Package of Velcro Strips
1x Roll of Soft Double Sided Tape
Step 3: Assemble the Parts and Build the Circuit
Once you have 3-D printed all of the necessary parts and purchased all other necessary components, it is time to start assembling Zippy! Refer to the first picture in this instructable in order to visualize how everything is put together.
The 3-D printed frame is very intuitive to put together, which is how I intended it to be. The two arms interlock to make an X frame and there is a bracket that fits over the arms. The electronics holster goes under the arms. The fan adaptors get mounted on the ends of each arm and the wheel adaptors slide right on to the legs of the frame. It should be very intuitive where to apply all the zip ties, however, if it is not, just look at the first picture on this intstructable! It is not absolutely necessary to apply zip ties in order to hold the top bracket onto the arms.
Once the frame has been assembled, it's time to wire and mount the electronics. The ESCs get mounted to the arms while the motors are to be mounted on the fan adaptors. Both the ESCs and motors are mounted with zip ties. The polarity needs to be reversed between the ESCs and motors on the front left and rear right arms so that they rotate clockwise. The other two arms will have motors that rotate counterclockwise. Therefore the clockwise props will be mounted onto the front left and rear right motors while the counterclockwise props will be mounted onto the front right and rear left motors. These opposite rotational directions produce opposing torques which assist in the stable performance of the bot.
Use velcro to mount the Arduino case as well as the LiPo battery on top of the center bracket. Use double sided tape to mount the IR sensor at the top center of the Arduino case, that way, it is in an optimal location to receive signals from the remote. All of the power distribution from the LiPo to the ESCs is fed through the electronics box which sits in the electronics holster. The signal wire from the Arduino to the ESCs are also fed through the electronics box. BE VERY CAREFUL not to criss-cross the wiring from the LiPo to the ESCs. This can easily damage the ESCs and potentially start a fire.
Refer to the circuit schematic which illustrates how everything is wired together.
Step 4: Flash the Arduino
Once Zippy the Fanbot has been assembled, it's time to flash the Arduino with the necessary software. I have provided the Arduino sketch that is used to control Zippy. The code essentially requires 5 buttons to operate the fanbot. The best buttons to program are the navigation buttons on the remote control. It is intuitive that the up/down buttons will move the bot forwards/backwards while the left/right buttons will rotate the bot counterclockwise/clockwise. The center navigation button will act as a kill switch and stop all motors. If the remote you are using does not work with this code, remove the propellers from the bot and use the serial monitor in the Arduino IDE to reprogram the Arduino to work with the directional buttons on your remote. You simply need to press the button you want to use and observe what value shows up on the serial monitor. Then, replace the value in the appropriate if statement that is in the code I provided with the value you see on the serial monitor.
The code is rather simple as you will see. There are 5 conditional checks which determine which button is being pressed. For example, if the IR sensor detects that the up button is being pressed, the two front motors will spin, which pulls the bot forward. If the left navigation button is pressed, the front right and rear left motors will spin causing the bot to rotate counterclockwise. If a button for a certain maneuver is held down, the respective motors will continuously increase their speeds until a max speed is reached.
Let's say for a second that the bot is moving forward with its front motors spinning at their max speeds. If the user presses and holds the down button, the front motors will slow down until they have completely stopped and then the rear motors will activate and send the bot in reverse. This applies to the bot's rotational maneuvers as well. This allows the user to speed up or slow down the maneuvers that the bot is performing.
Now, let's say the bot is again moving forward at some speed. If the left or right directional button is pressed, the bot will immediately stop spinning all motors before activating the motors that make it turn. Therefore, the user can immediately switch between linear and rotational motion.
Step 5: Have Fun Using Zippy and Be Safe
Now you are all set! Once you have built Zippy and gotten the Arduino code to work, it is time to play around. Be extremely careful though, especially around kids and animals. Make sure the propellers are balanced well and tightened down snug on the motors. The brushless motors used in this project spin at very high RPMs, therefore, the props are very capable of causing injuries. Have fun!

Postmortem changes in protein composition up to 24 h in bovine longissimus thoracis muscle were investigated by two-dimensional gel electrophoresis and MALDI-TOF MS/MS. A total of 47 spots were significantly changed the first 24 h postmortem. The 39 identified proteins can be divided into five groups: metabolic enzymes, defense and stress proteins, structural proteins, proteolytic enzymes, and unclassified proteins. The identified metabolic enzymes are all associated with ATP-generating pathways, either the glycolytic pathway or energy metabolism. In addition, several defense and stress proteins were changed in abundance in this study. These findings contribute to a better understanding of the biochemical processes during postmortem storage of meat.
