The phones next year will be able to recharge 50% in only 10 minutes.
Anker, founded by a former Google employee, is developing this technology that will enable even faster charging of phones.
Considering the fact that we can not wait for a significant increase in the capacity of the batteries, most of us fill up their phone at least 2 times a day. While making progress in battery technology, all that remains is the technology for their fast charging, which to some extent compensates for the lack of better batteries.
Once the phone has to be charged several times during the day, at least that charging takes a short time, so avoiding the waiting time before the device can be taken and freely used outside or in the bed where we do not have a charger us.
The phones already have a fast charge that allows most of the phone to recharge in 30 minutes, but Anker wants to reduce this time to 10 minutes. Specifically, the technology developed by this company should allow charging 50% of the battery of the phone in only 10 minutes, which can be freely said that this is already more than a high enough speed.
The technology they develop will work through the USB Type-C standard, which would be surprising if this is not the case, and is called a “filling pump”, or better in English, the original “charge pump”. This technology is expected to be the basis for making its fast-charging systems for companies already doing it, such as Qualcomm, for example.
The technology will work at 50 watts, and one of its biggest advantages is coping with excess heat generated when charging a device.
The expectations are that next year’s phones can come with this technology and with these devices we are constantly using them, we can fill them up as quickly as possible.


Sense ultrasonic amplitude changes and guard against unplanned downtime
Sense ultrasonic amplitude changes and guard against unplanned downtime!
The Ultra-Trak 750 shows you early warning signs of:
- Mechanical failure
- Valve leakage
- Flow disruption
- Arcing by detecting changes of ultrasonic amplitude
How it Works:
The Ultra-Trak senses high frequency emissions produced by operating equipment. A baseline threshold can be set within a wide dynamic range of 120 decibels. Once set the Ultra-Trak then monitors changes of ultrasonic amplitude within a range of 40 decibels. The Ultra-Trak can be connected with other devices to provide alarms or for tracking potential problems over time. In some instances the Ultra-Trak can be used for sound level increases, such as to warn of onset of valve leakage or bearing failure. Amplitude fall-off can be used to signal line flow disruption or alarm of machine shutdown.
Ultra-Trak is ready to guard against unplanned downtime and product loss the minute it is installed. Ultra-Trak passively monitors ultrasounds produced by operating equipment. It can be readily connected to alarms or recorders for data logging, thanks to its 4-20 mA current output, coupled with a pure demodulated output.
Housed in stainless steel, the rugged Ultra-Trak 750 is water resistant and dust proof, which means it can be externally mounted in some of the most challenging environments. Couple this with an extraordinarily wide dynamic range of 120 dB and sensitivity adjustment; this sensor is ready to meet your most demanding sensing needs.
UE Ultra-Trak 750 Features:
- Demodulated Output for Analysis
- Dynamic Range: 120 dB
- Sensing Range 40 dB: Once the sound level is set, there is a 40 dB monitoring range.

I enjoyed good coverage in these three municipalities.
In Brooke’s Point:
In remote Barangay Isugod:
I brought two phones. One had a Smart SIM while the other had a Globe SIM. I was being cautious since I didn’t want to suffer a loss of coverage because of poor reception. That’s why I brought both SIMs. Fortunately, I never had to resort to one phone because of poor coverage of the other. The two competitors kept pace with each other. Their towers were always less than a kilometer apart and, typically, near the town’s center. At Brooke’s Point, for instance, Globe’s tower is located closer to the town center than Smart’s but I just can’t find the photo I took of it.
Bottom-line: You’ll survive with one SIM but considering how inexpensive SIMs and phones are, you might as well bring both.


Below in this page, ValidNewsToday is here to Explore on the new issue that many WhatsApp users is facing as the app continues to display connecting to users and never connected to many users across the globe.
So yh, if you’re facing same issue on your WhatsApp app, know that you’re not alone and many reports that they receive a message saying ‘connecting’ on their WhatsApp app and they have took to Twitter to report the issue.
This had started on Tuesday, October 25th morning and user can’t access their can access their conversations, however, they can’t send or receive messages at this time.
Users in UK has particularly report that the app keeps saying ‘connecting’ when they try to send a message to someone else and a message saying ‘Make sure your computer has an active internet connection’ appears when they try to make a call.
According to many also, they are unable to send message and received the clock symbol when they attempt to send a message.
As for a fix, at this time there is none and WhatsApp own by Meta is yet to comment on it but our guess is that the servers is down or a glith and it won’t take time before the issue is fixed.

At a recent #BCTechSummit HyperLedger Indy developer bootcamp event in Vancouver, I was fortunate to be part of a conversation where Sam Curren (@telegramsam) was talking to a small group of developers about the importance, over the course of history, for Internet protocols to not only be open, but more importantly, open to innovation …innovations that might succeed as well as innovations that might fail.
“If you look at important Internet protocols like TCP-IP that enable packets on a network to carry any type of data including text, email messages, web pages, etc, and, later on, streaming audio and streaming video, who could have imagined it? It’s vitally important for Internet protocols to not only be open but open to innovation …innovations that might succeed as well as innovations that might fail. No one can foretell how the specifications we’re creating today will be used in the future.” Sam Curren, March 11, 2019

I/O: Really, the core function of a microcontroller is Input/Output. In fact, out of the ATmega32's 40 pins, 32 pins are set aside for I/O. They are organized into four 8-pin ports named PORTA, PORTB, PORTC, and PORTD. The STK 200 makes it really easy to access these ports by giving them each headers. The board even labels the headers using the standard naming convention established by the AVR family (PORTA, etc.). Each header includes it's own VCC and GND, which devices almost always require. LEDs and switches are probably the most common form of I/O; conveniently, the STK 200 has 8 LEDs and 8 switches built into the board. You can dedicate ports to the LEDs, the switches or both using a 10-pin ribbon cable provided with the board and pictured below. PORTB is lined up with the LED input header and PORTD is lined up with the switches output header for an easy connection.

Net Neutrality is about inhibiting network providers from controlling bandwidth hogs such as Google and other companies that wish to put huge amounts of data of the network that affect quality of service of all network customers. It penalizes network companies who work to prevent network outages and provide better service. I prevents you from using the Internet unemcumbered by bandwidth hogs. The network companies and you will suffer the backlash of this proposal. This legislation threatens the Internet. The Internet is not free and never has been. It costs money. The government does not fund the Internet and its attempt to regulate the Internet is absolutely in no ones best interest.

We live in a world where information and how to apply this information has huge potential to affect change in our everyday lives, whether that is simply controlling the environment which we live in or improving the quality of the built project. Internet of Things (IoT) is an innovative move towards the utlisation of data and its application in our day to day experiences. And while it is not new it is progressing at a rapid rate. According to Cisco there will be 50 billion connected devices by next year.
An IoT ecosystem is made up of web-enabled smart devices that use sensors and communication hardware which when connected through the internet enable the exchange of data which can then be analysed without the need for human to human interaction. This data can be used to create a desired action or act as a key reference point to enhance the process within a given field. Because it is highly personal and based on actual data it is highly effective in creating a more tailored and personal experience allowing us to manage and control our environment based on our daily routine.
Information gathered allows users to personalise their own homes remotely based on their daily routine by allowing the management and control of areas such as room temperature or by intuitively assessing actual heat gain according to the number of people within a space and adjusting accordingly. By connecting our home to our smart phone we can control the heating and the lighting to switch on or off even when we are not at home.
Imagine a 40 storey residential building with 400 apartments. Each tenant has one car which requires an access card to enter the building’s parking and which takes three seconds each time twice a day amounting to around 240 hours per year. By linking your smart phone or your car’s GPS system to the gate that results in a saving of at least two-thirds of this time – around 160 hours. Time is, after all, a precious commodity.
There are many benefits of IoT’s role in our personal environment however for the MEP engineer having access to real information about the customer and user requirements helps make the end user’s lives much easier and more comfortable.

Today, we take many past technological advances for granted. The women in this photo, however, would presumably have appreciated the “miracle” of the telephone. They were early telephone operators in Lansing, Michigan. When this photo was taken – in 1885 – Lansing had only had phone service for five years.
Lansing Telephone Service: In the Beginning…
Alexander Graham Bell patented his telephone in 1876. In 1880, William A. Jackson, general manager of Detroit’s Telephone and Telegraph Construction, established phone service in Lansing (Telephone and Telegraph Construction established phone service in Detroit three years earlier.). At first, only sixty Lansing residents subscribed to the service. The next year, Lansing’s first telephone directory listed ninety-three names (but no telephone numbers). Lansing received a limited amount of long-distance service in early 1883, when a telephone reached to nearby Mason. Later that year, another line reached from Lansing to Detroit. By 1898, Lansing boasted 400 phones and a greatly expanded long distance service.
Lansing Telephones in the Twentieth Century
Alexander Graham Bell’s original telephone patent expired in 1893. As a result, more phone companies formed as the twentieth century approached. In Lansing, the newly-established Citizens phone company competed with the Michigan State company. The competition ended in 1923, when Michigan State bought out Citizens. In 1924, Michigan State became Michigan Bell.
Technological advances changed how people used their phones. In 1902, Lansing’s hand-crank phones were replaced by a “common battery system.” With a common battery phone, a caller could reach an operator by simply lifting the receiver. A modern-style dial operation went into effect shortly after Michigan State/Michigan Bell gained its monopoly in 1923. In 1954, Michigan Bell’s Turner office (located on Jolly Road) became the first Lansing location to use a new phone number system. Under this system – which spread to all of Lansing in 1955 – each phone number consisted of two letters followed by five numerals.

Before you consider a Wi-Fi extender, consider this scenario. The day has commenced, and your deadlines are up to your neck. The kids are finally seated to do their homework. Your important emails are only a click away, and you must tick some work off your to-do list. That is when it happens. The website starts loading, loading, and keeps loading.
The pandemic struck world has already restricted millions across the globe to work from home, and given the circumstances, a bad Wi-Fi signal is the last thing you need. Since a lot of people shelter in place and work from home more than they used to, it is extremely important to figure out a way to make your internet connection faster.
The good news is that with a Wi-fi extender even the dead zones around your house can now be covered. This device provides ample amount of Wi-Fi signal throughout the premises. Use this quick overview of the 5 best Wi-Fi extenders you can buy to boost your connectivity.
What is a Wi-Fi Extender and How Does it Work?
A Wi-Fi extender is a device that is connected to your existing Wi-Fi router to help extend its signals across the dead zones in your house. It connects either through a wired connection or wirelessly, depending on the type of Wi-Fi device you have. All you need is a router attached to your internet device for an extender to work. The extender usually sits between your Wi-Fi router and the area where you require strong Wi-Fi coverage.
An extender basically acts as a middle-man to enhance the connection from one point to another. As soon as a connection between your router and an internet-connected device has been established, the Wi-Fi extender takes hold of the existing signal and re-broadcasts it on a different channel using its position. This allows a wider range of signals to reach your entire household.
However, for optimal performance, the Wi-Fi extender must be close enough to the router to grab the signals but also far enough to be able to broadcast those signals to the area where you need a stronger connection.

A new buffer-sampling system could be a boon for devices such as buffer-snaps and SMM, which can be used to monitor and control devices in a range of situations, from high-risk areas to health care, and even medical emergency response, according to a new study by University of Illinois at Urbana-Champaign scientists.
Buffer-samplers, or buffers, are devices that can be installed in smartphones and tablets, which enable a device to capture video and audio data in real time, including a buffer of some kind that can then be sent back to the phone, tablet, or other device for later analysis and processing.
Buffer-snapping devices, which are similar in functionality to buffer-snapshots, can be programmed to automatically send the video data to the buffer as a video signal, without having to wait for a buffer to be created.
However, the new study, published in the Journal of the American Medical Association (JAMA), found that the most commonly used buffer-slide and buffer-time devices, buffer-based devices that capture video on demand and are programmed to send it as a signal to the smartphone or tablet, do not have the features that make them a good option for buffer-sensing devices.
Buffer systems, which were introduced for the medical field and are increasingly popular in the healthcare industry, have been around for years and have been used to detect blood clots and other blood-related conditions.
In the past few years, the industry has come up with some innovative buffer-related features to increase the device’s range of use, but the researchers say the devices remain relatively simple and relatively inefficient.
According to lead researcher and doctoral student J. David Schoenfeld, MD, a senior lecturer in the Department of Emergency Medicine at the University of Chicago, buffer systems, even when programmed correctly, tend to be too small and slow.
Buffer systems are generally limited to a few minutes of video recording time per device, with a buffer that is only two minutes long.
Buffer timings can vary between devices depending on how many buffers are connected to the device, as well as the device itself.
“The device is a buffer device,” Schoenfield told Digital Trends.
“It has some buffer capabilities, but there’s no buffer capability.”
Buffer systems have become an important component of emergency response and health monitoring for devices that have been designed for specific scenarios, such as ambulance services, military vehicles, hospitals, and more.
Buffer devices can be configured to record video on-demand, such that the video can be sent to a phone, and then automatically send it to the medical device for processing and analysis.
But buffer-systems often fail to capture all the data that a device can do, because they have no data buffer.
The problem is compounded when devices are designed to monitor patients.
For example, a device may have an active camera on the front that captures a video image and sends it to a device that can analyze it, but that device can only capture the video that the camera is capturing, and not the video captured by the camera, according the researchers.
When a buffer-enabled device is designed to capture multiple types of video at once, that can result in a large amount of data.
“When you see all the video you want to capture, it’s like having a whole bucket of buckets of data,” Schoelds said.
In this study, Schoenfeld and colleagues set up a system where devices that were designed to do the buffer-type of work were tested for video quality.
In addition to analyzing the video quality, the researchers tested the devices’ latency to complete their buffer-processing tasks.
Buffer technology can be designed to send the data to a buffer on demand, but this type of latency can be up to 30 milliseconds, and buffers have a maximum data rate of about 1,000 samples per second, the team noted.
A buffer can only process a portion of a video stream at a time, so the device can’t be used in an automated way to analyze the video to find the best way to capture the data.
“We wanted to design a device for the job of being a buffer system,” Schochs said, adding that buffer systems can be effective when they can capture data at a rate that is at least 50% of the video signal’s total duration, which is often the case when working in a medical environment.
Schoenfeld said buffer-style devices, however, may not be the best solution for the large amount to be captured by buffer-switched devices, since the device has no data buffers, while the buffer devices can.
“The buffer devices do a poor job of capturing video,” Schuchs said.
“The main question for us is, can we design a buffer for the buffer device to be a buffer?” Schoen


This class was designed to allow to communicate using a serial interface (usually RS-232 serial port). This class inherits from Stream class, so you can use standard streams methods to send and receive data, and to close the port.
You stick the prom in your breadboard, and wire it up to the appropriate ports and pins of the Arduino, which bit bangs the prom and returns the results though the serial connection of the Arduino. Using a terminal program on the pc side you capture the text and use a script to convert the ascii values into a binary nibble format and save as hex.
It is defined in software as far as the Mpeg2 encoders and the multiplexer. These stages are set by software using Ubuntu Studio 10.04 this is a form of Linux used as the Operating System (OS), using shell script files. The code used is based on C programing language and lets me plug into various software modules. To assemble data packets as a DVB transport stream made up of 188 bytes , that can be sent to/or from any device on the network. Such as Xbox Media center or any number of computers. This is where I took advantage of the User Datagram Protocol (UDP), this protocol is ideal for sending DVB packets. As the name suggests the user sets the packet framing and any handshaking that maybe required. All that the UDP does is set up the IP address to send to and the port-mapping. in this form the UDP will be able to run over network within the LAN IP structure. To recover this data I use an Internet Protocol (IP) to Asynchronous Serial Interface (ASI) converter. This converts to an ASI signal to feed into a L-band (950 to 2150 MHz) Quadrature Phase-Shift Keying (QPSK) modulator. By taking this approach I have kept the cost down to a minimum, where by most of the parts were source from Trademe a local form of Ebay. Such as, Mpeg2 encoder cards, the Satellite tuner cards and a computer to run the required software.
This is done by using the advanced IP settings. First, work out the outside IP address and the IP address to be sent to. There are websites to display your Internet IP address. (www.speedtest.net or www.att.com/speedtest. Next, open UDP port 1234 through your firewall, to and from a local computer within your local area network. When this is done at both ends, you can send a DVB TS unicast via the Internet. Then it becomes a simple case of re-multiplexing your mux for transmission into a local DATV repeater.
I've had a few problems with my local mail provider so I've had to work out a few different ways to get sendmail working with my Linux system. My current setup is sendmail sending via my Google Mail account. I had a working setup with my 1 and 1 service but I'm missing something important and I can't get that working anymore. I also had a working Comcast setup but I'm finding that Cocmast is interfering with my mail so I switched to Google mail.
Explanation: It is generally defined as the software designed to enter the target's device or computer system, gather all information, observe all user activities, and send this information to a third party. Another important thing about the spyware is that it works in the background sends all information without your permission.
All you supply is a cable to the computer (a standard serial cable or a USB serial port -- you can order them as options or use your own; the GP-3U is a GP-3X board with a built in USB port in which case you need a standard mini-USB cable) and a DC power supply or 9 volt battery. The GP-3 has an onboard 5V regulator, or you can supply 5V regulated directly to it.
All the GP3 boards have pins on either .2" (GP-3X) or .1" (all others) spacing. You can easily connect these to prototype boards to get more space. We especially recommend using our PROTO1 board as "wings" (see photo above that shows two wings installed). You can add one to either side of the board or add two to maximize the space for custom circuitry. The hole pattern is handy (see photo) and will allow you to add ICs, relays, sensors, or anything else you need to use your GP3. If you plan to use wings, you'll probably want to order the board without screw terminals unless you intend to mount the screw terminals on the wings.Which kit is right for me?Exactly which kit you need depends on what you want. If you want to plug the board into a solderless breadboard the GP-3 or GP-3B are easiest. The GP-3 allows you to select 9 signals and send them to the breadboard (the rest are available, but not on the breadboard). The GP-3B brings all pins out to the breadboard.The GP3-X (and GP3-XU) can plug into a breadboard but since it has pins on each side, it isn't always as convenient. However, as an option you can get the GP-3X with screw terminals which makes hooking things up withouta solderless breadboard much easier. GP-3X - Best value. Serial port and many customizable options. Optional screw terminals, space for extra circuitry, and handy GP3EZ jumper. Available assembled or in kit form.GP-3XU - The same great kit as the GP-3X but with a USB daughter board that provides communications and power to the board.GP-3 - The original. Very small form factor and easily plugs into a solderless breadboard providing a user-selectable subset of the I/O pins to the breadboard.GP-3B - A GP-3 built on our GPMPU40 Universal Board. Plugs into a breadboard with lots of room for custom circuitry. Dedicated GP3EZ jumper.You can read the GP-3 Manual for more details on each board. If you aren't sure, you probably want the GP3-X. 2b1af7f3a8


The transaction, which will be worth South African Rand 6.55 billion, will create the largest pan-African broadband network
Tata Communications Ltd has entered into an agreement to sell its South African telecom unit Neotel Pty Ltd to Liquid Telecom Group, run by Liquid Telecommunications Holdings Ltd of Africa, for South African Rand 6.55 billion.
Liquid Telecom, majority owned by Econet Wireless Global, is partnering with Royal Bafokeng Holdings (RBH), a South African empowerment investment group, which has committed to take a 30% equity stake in Neotel.
A proposed deal by Tata Communications with Vodacom SA to sell Neotel had lapsed citing regulatory complexities in March. On 10 December, Tata Communications said that it will sell the fixed-line assets of Neotel to Vodacom, a unit of Vodafone Group Plc, in a revised deal that excludes Neotel’s wireless spectrum and licences. The deal was hanging fire for more than two years in protracted negotiations.
“The transaction, which is subject to obtaining all affirmative approvals and other corporate approvals that may be required by the shareholders of Neotel and other regulatory approvals, is transformative and will create the largest pan-African broadband network and B2B telecoms provider. Through a single access point, businesses across Africa will be able to access Liquid Africa’s 24,000km of cross-border, metro and access fibre networks. These currently span 12 countries from South Africa to Kenya, with further expansion planned,” Tata Communications said.
The transaction is subject to approval by South African regulatory authorities and is expected to be completed later this financial year. This move would have may also help Tata Communications pare its debt of Rs.9,595.22 crore as on 30 September 2015.
Nic Rudnick, Liquid Telecom’s chief executive officer, said the company is excited about this transaction.
“Leveraging the strengths of RBH, Neotel and Liquid Telecom will offer an unprecedented fibre network with a unique set of services and international connectivity for telecom operators and enterprises across sub-Saharan Africa. For the first time, African companies will be able to connect with each other in a cost effective and reliable way, all on a single fibre network. We will also be increasing investments into Neotel to cater for rapidly accelerating mobile and enterprise traffic, enabling us to launch exciting new products and services,” Rudnick said.
Vinod Kumar, managing director and chief executive officer, Tata Communications, said Liquid Telecom is the right partner for the next phase of Neotel’s evolution.
“Convergence of technologies and services will be the key driver of growth across the globe and this transaction will encourage inclusion and support the growth aspirations of the African continent. We believe that Liquid Telecom will deliver on the vision of a well-connected Africa, which will augur well for the South African telecom industry and Neotel’s customers,” Kumar said.

The Aqua-Minder is an intelligent control system designed to switch off water supply when it is not needed. The Aqua-Minder has been created to be used in conjunction with the Secomak AquaRinse.
By using the Aqua-Minder with a sensor or linking through to the machine controls, the water supply can be switched off when not needed, reducing water consumption and cost.
The Aqua-Minder can be used with a variety of sensors and has an inbuilt timer to control how quickly the unit will respond to the sensor and shut off the supply. The software analyses the sensor to detect both line stoppages and gaps in production and start up is instantaneous once a moving object is sensed again.


Each of the two B channels supports data speeds up to 64Kbps and can be combined together to provide data speeds up to 128Kbps. Each of the two B channels can also be used for phone and/or fax calls. For example, you can surf the Internet at 64Kbps using 1 B channel and make or receive a phone call on the 2nd B channel.
With ISDN, you can be surfing the Internet at 128Kbps and be ready to take calls. It works like this: You're surfing the Internet using both B channels, going 128Kbps. A phone or fax call arrives and you answer it. Your ISDN line will drop from 128Kbps to 64Kbps (1 B channel) for Internet surfing for the duration of your call (taking place on the 2nd B channel). When the call is complete, you resume Internet surfing at 128Kbps!
Please note that the phone and fax capabilities described above, as well as the two phone numbers, are dependent on your ISDN Modem.
Do you have more than one computer at home? With an ISDN router, two or more computers can be connected to the Internet or an Office LAN over one line.
Back To Top
Compared to normal analog and dial-up modem connections, you will be amazed at
how fast ISDN is, but it's not just the 128 Kbps speed that makes ISDN so marvelous. It's the flexibility of how you and your family can use this new communications power. For
example, some of the main advantages of using ISDN
for Internet access include...
top data rate is four times faster than a V.34 modem and nearly nine
times faster than V.32bis modems.
SETUP TIME - ISDN
sets up calls in just 300 milliseconds. Compare that with the 15
seconds your analogue modem takes!
RELIABILITY - Digital
lines are virtually error-free. Analogue calls, on the other hand, are
subject to interference, which may corrupt your data and cause your
modem to fall to slower speeds.
Other advantages include;
- better use of your time spent on the Internet, or while connected to an office network
- less frustration
- less wear on your patience
- no more missed phone or fax calls because you were on the Internet
- greater connection stability
- quicker file downloads
- clearer, better video conferencing
- the ability to connect two or more PCs to the Internet over just one phone line
How Fast Is It?
ISDN transmits information at up to 128Kbps. The table below shows how this speed compares to others, in terms of screen painting and file downloads.
|ISDN vs. ANALOG||
|14.4 Kbps Modem||27 sec||9 min||7.7 hours|

Is ISDN Right For You?
The need for rapid home-based communications isn't some imagined scenario of the Way Things Ought To Be. It's today's reality! With so many employees working at least partially from home and doing more tasks through modem connections (banking, shopping, etc.), the combined voice and data capabilities of ISDN offer real benefits to help get work done quickly. ISDN makes sense for busy people, including telecommuters, small office/home office
(SOHO) workers, Internet surfers, consultants, contract workers, business executives, researchers, teachers, and customer service representatives. You are a candidate for ISDN if you:
- Telecommute and must connect to an office network.
- Feel that your Internet activity is both time-consuming and frustrating.
- Operate a home-based business.
- Miss important phone and/or fax calls because you are juggling your telephone line to access the Internet.
- Download large files on a regular basis.
- Find the Internet painfully slow.
- Feel locked out, because of speed, of certain Web-based communications, such as video conferencing and high-bandwidth multimedia and virtual reality "experiences".
What You Will Need
To have ISDN at your home you will need the following:
An ISDN lineBack
An ISDN Modem or Router
A connection to the Internet through GCR or connection through an office LAN
A computer supporting these suggested minimum requirements:
PC: 486,75Mhz, 8 MB RAM, 15 MB HD space, 16550 Serial Port (for external devices only)Inside Wire (see below)
Macintosh: 68030, 8MB RAM, 15 MB HD space
How Much Does ISDN Cost?
The cost of ISDN has
been dropping over the past year as more and more people are turning to ISDN for
high speed internet access. Sprint allows you unlimited use of
an ISDN line once you have it installed, Bell Atlantic on the other hand offers
several per-hour monthly packages. The packages range from 20 hours to unlimited.
- The first thing
you will need to do is have an ISDN line installed in your home.
will occasionally run specials that waive the installation fee but can charge as
much as $200 for the initial set up ISDN of service on your phone line.
For more information on Sprint's installation fee, contact your local Sprint office.
Atlantic charges a one time line connection fee of $125
Their per-hour monthly packages are as follows;
E L L A T LA N T I C I S D
N R A T E S
B channel usage
of hrs if both B channels are always used
Package for you, if your monthly usage is (hrs):
- A typical ISDN modem will run in the neighborhood of between
$200 - $250 depending on the brand name you choose. For a custom quote on
an ISDN modem, contact one of our friendly GCR sales associates at (804)
Line Charges -
Once your phone company has installed an ISDN line at your house, the cost is
typically $40 for residential and $60 for businesses per month. This is in
addition to your existing phone line charges.
- For individuals with existing GCR
accounts, there is no additional charge for 64K ISDN connection and no set-up
fee. For rates on 128K connection, please check out our schedule

ISDN uses the same wiring as your analog POTS (Plain Old Telephone Service) wiring: twisted pair. But there are some differences you should know about.
For regulatory reasons, the wiring that provides your telephone service, whether POTS or ISDN, is divided into two parts: there's the
Sprint-owned network outside your home; and then there's your personal premises wiring on the inside of your home. These two are connected at the Network Interface Device
(NID) that exists on your premises. The place where they join is called the demarcation point (or
The Network Interface is found on the outside of your home, in your basement, or, in an apartment building, in the telecommunications closet.
The telephone company provides services up to the demarc. However, all services performed on the premises-side are your responsibility, including installation and maintenance.

ISDN: The Inside (Wiring) Story
You have three options for installation of any necessary wiring and jacks on the premises-side:
You can do the installation yourself,
You can have another party do it, or
You can hire Sprint or Bell Atlantic to do the installation.
On a time and material basis or a one-time fee (depending on where you live and the configuration required),
Sprint will extend the wiring from the NID to your ISDN modem.
New wiring vs. existing
If you are converting an existing line from analog to ISDN, you may be able to use the wiring that is already in place. We recommend that the wiring be run directly from the Network Interface to the ISDN jack and that no devices, other than the ISDN modem, be connected to the wiring in between. New wiring would, of course, need to be a direct run, too.
RJ-45: the preferred plug-in
Whether existing or new wiring, we recommend that you install an RJ-45 jack for two reasons: (1) It is the ISDN standard, and (2) It's bigger than the RJ-11 jacks terminating your analog lines (so you are less likely to plug your ISDN modem into the analog jack and potentially damage your equipment). However, an RJ-11 jack can be used for your ISDN line. RJ-45 jacks and wiring are available through most electronics stores.


The Open Source Meter is based on the CS5463 metering chip. The basic Theory of operation of the CS5463 is it is a dual-channel analog-to-digital converter (ADC) with a complex computational engine that performs power calculations and energy-to-pulse conversions. The metering chip has a number of measurement functions that are applicable to both power monitoring and power quality monitoring.
Voltage and Current Measurements
The meter can perform Vrms and Irms calculations. The calculation is the root mean square calculation performed on N instantaneous voltage and current samples.
The meter can perform Active power calculations by taking the instantaneous voltage and current samples and multiplying them to obtain the instantaneous power. The product is averaged over N conversions.
The meter can perform reactive power calculations by using QTrig (Trigonometric Identities) with the formula
The average reactive power is obtained QAVG by averaging the voltage multiplied by the current with a 90deg phase shift difference between them.
The apparent power is the combination of the active power and the reactive power, without reference to an impedance phase angle
The power factor (PF) is the active power (PActive) divided by the apparent power (S)
Fundamental Active/Reactive Power
The Fundamental active and reactive power (PF) and (QF) is calculated by performing the discrete Fourier transform (DFT) at the relevant frequency on the instantaneous voltage and current. Epsilon is used to set the frequency of the internal sine (imaginary) and cosine (real) wave form generator. Epsilon is used to achieve unity gain at the line frequency and to attain accurate QAVG results over line-frequency variation.
Harmonic Active Power
The Harmonic active power (PH) is calculated by subtracting the fundamental active power (PF) from the active power (PActive) inversely reactive power can be calculated.
Sag and Fault Detect
Voltage and Current Sag thresholds can be set to the average of the absolute instantaneous voltage and current respectively.
Sag and Fault Detect
Temperature readings can be obtained in the Celsius scale.
It is important to note that the OpenSource Meter is not a real-time device and should not be used in highly deterministic applications. Time lags can be expected no larger then 20 milliseconds.


AWS to talk IoT at AWS Summit Sydney
“We understand that for many IoT use cases, IoT data needs to be collected, processed and actioned at the edge – where the customer’s business runs,” he told IoT Hub.
“To reflect that, we will be showcasing the capabilities of AWS Greengrass in delivering IoT edge intelligence with integration to other services such as Amazon Rekognition and AWS Machine Learning solutions.”
AWS Greengrass, Hickin explained, is software to run local compute, messaging, data caching, sync, and machine learning inference capabilities for connected devices in a secure way.
“With AWS Greengrass, connected devices can run AWS Lambda functions, keep device data in sync, and communicate with other devices securely – even when not connected to the Internet,” he said.
“Using AWS Lambda, AWS Greengrass ensures your IoT devices can respond quickly to local events, use Lambda functions running on AWS Greengrass Core to interact with local resources, operate with intermittent connections, stay updated with over the air updates, and minimise the cost of transmitting IoT data to the cloud.”
A new feature, AWS Greengrass ML Inference, brings machine learning services to the edge. “It lets application developers add machine learning models to their devices and edge hardware so that complex machine learned models (prediction, classification etc) can be run and executed on the edge – close to the data,” Hickin said.


Δώστε ζωή στα μοντέλα σας και τις μακέτες σας με φωτισμό χρησιμοποιόντας FIBER OPTICS
Fiber Optics- Practical Application Tips
How does it work? Think of optical fiber as magical moving a piece of light from the source (a distant light bulb) to the point where you want it. To move hundreds of points of light to the exact places they are needed can easily be done, provided you do a little planing. These hints will help you successfully plan how to light your model using optical fiber.
Note: Wiese instructions may at first glance seem difficult, but do not despair. It is rather like trying to describe how to tie a knot without waiving your hands to aid the description process. Lighting with optical fiber is easy once you have done it.
The first design question when using optica1 fiber is "Where will the Light Come From?" Most models have an internal cavity. A small model can often hold a pen size flashlight, if the batteries can be replaced and the light turned on and off, the model will be able to be independent of at base. Another option for getting the light into the fiber is to have the bulb (halogen works well) in the cavity, with current wires running to the bulb through the supports. With large displays, such as architectural models, putting the light source in the base and running the fiber into the model works well. This allows for air flow to cool a more intense light source, as well as lighting several separate buildings at the same time.
Think about heat! If you run a 100 watt bulb in a box with out ventilation it is going to get hot. Provide ventilation if you plan to use more than 15 watts. For the best effect use a small bulb with the fiber abutted to the bulb. At temperatures over 80C the plastic fiber will slowly yellow, over 95C will soften and melt.
Having decided where the fiber is to be positioned cut more than the right length of fiber, a least a few inches on each end for handling. The fiber is easily trimmed, but is very hard to splice. Attach the fiber at the external end first, and gather the fibers into a loose bundle that terminates beyond the light source (this allows a working and handling length), The emitting end of the fiber, the one that is seen, can be trimmed flush with the face of the model, or left standing depending on the effect desired. Often this means drilling a hole for the optical fiber in your model. Position the fiber in the hole with an extra inch hanging out, glue the fiber and pull it through from the far side so the glue is pulled into the hole. When the glue is dry trim the fiber with a sharp knife.
Leave a bit of slack when tacking it down at the second end. This assures you that the fiber is not bearing any load or stressing the model. Group the inpUt ends together into a bundle, The fibers will accept more light if they are polished and do not cast shadows on each other, Trim the longest input ends with a knife. Loosely twist-tie it into a bundle with wire, tap the group end flat and tighten. Dip the bundle tip in clear epoxy so that it wicks up between the fibers. When dry sand with 440 grit paper or file the grouped end flat, and polish by rubbing on white bond paper or with extra fine jewelers rouge. It is common to have several separate bundles using the same light source.
Use two part epoxy rather than super glue or other one part glues! The solvent base of many one part glues dissolves the fiber. Test your glue on a piece of fiber before attaching to your model. (Devcon five minute epoxy works well, but if you have access to another type, try it first.)
Colored lights are made by tinting the incoming light. Use either colored cellophane or translucent paint. The lights can be made to blink different colors by passing a clear wheel between the fiber bundle and the light source. Paint the wheel with translucent colors to match the pattern of output you desire. Turn the wheel with a clock motor.
The fiber can be made to expand by heating it. The results vary with time and temperature, and a steady hand helps. By passing the end near a heat source (such as a soldering iron) it will contract in length and expand in diameter. The fiber will burn if you pass it through an open flame, so use caution.

In this day and age, everything seems to be heading the way of wireless. From earphones and computer mice to landline phones and charging docks for mobile devices, we are now seeing more and more applications of wireless technologies in our everyday lives.
One of the most popular applications of wireless technology is internet connectivity. These days, it’s not uncommon to find a home with a Wi-Fi router or a cafeteria with a high-speed wireless connection that’s popular among customers and freelancers. But beyond enabling connectivity to the Internet for domestic and commercial consumer applications, wireless technology can also be used for home and office surveillance systems. Apart from being easier to install than a wired system and increasing the value of the home or office space, wireless surveillance solutions also provide several other benefits that traditional home and office security systems simply can’t offer.
Increased Safety and Security
Traditional security systems are usually connected to telephone lines, which tech-savvy criminals know how to cut in order to deactivate and disconnect from alarms. Wireless security systems, on the other hand, use cell phone frequencies and are often powered by batteries that last up to five years, so you can continue to monitor your home even if telephone or power lines go out.
Another distinct advantage of a wireless surveillance system is that it allows users to connect to the system and monitor activity from anywhere using a smartphone, tablet, or desktop computer. You don’t have to wait to review the footage because you already have access to live footage, and you can therefore alert the authorities as soon as an alarm is triggered.
Finally, wireless security systems are also less prone to physical damage like fraying, corrosion, or rodent bites, which can quickly escalate into technical malfunctions or become fire hazards.
Wider and Continuous Coverage
Having fewer wires to work with means you can install cameras and other surveillance devices almost anywhere, even in areas where running wires could prove difficult. This means that you can virtually eliminate blind spots in your surveillance system.
Wireless surveillance systems also mean you can easily incorporate a variety of devices in one network, depending on your needs and without worrying about overloading. Among these are motion detectors, night-vision and infrared cameras, 360-degree cameras, and varifocal cameras that have remote zooming and focusing capabilities.
Continuous monitoring, without worrying about recording over previous footage, is also a benefit of wireless surveillance system. The records are easier to keep, review, and reproduce as they’re all digitally stored either in large-capacity drives, the cloud, or both. This is especially important when you have something or someone that you want to keep an eye on all the time—like confidential documents at work or young children and elderly individuals at home.
Beginnings of a Smart Home or Office
The concept of smart homes and offices is quickly gaining popularity. With the help of a wireless surveillance system, you can begin automating your home or office in small ways by integrating other functions. Automatically turning the lights on and off depending on the level of activity is a good place to start. It’s a simple method to save on energy costs.
Other features include locking and unlocking doors (especially in high-security areas), automatically adjusting the thermostat as you receive weather updates, and arming or disarming part of or the entire security system. Best of all, these features can be integrated into your personal devices so you can activate them anytime you need.
Wireless surveillance systems are not without its limitations, however, and these include issues in signal quality and network interference. However, the benefits far outweigh the disadvantages, which in themselves can also be addressed with structural planning. Wireless surveillance systems also go beyond preventing crime; it can also give you peace of mind and promote an atmosphere of safety, peace, and security among family and personnel.


Because so many people use mobile phones, there is concern among medical researchers that any related health consequences, even small ones, may cause serious public health issues. It’s important to know the risks and potential effects of using your mobile phone and make your own mind up about how you’re using your mobile. There is a lot of discussion about the potential health effects of using cell phones. Through understanding what the risks are and how to avoid those, people can avoid health hazards.
Mobile phone health concerns:
Using radiofrequency (RF) radiation, mobile phones communicate with base stations. It has a’ thermal’ effect if RF radiation is high enough, which means it raises body temperature. There are issues that low RF radiation levels released into the atmosphere by mobile phones may cause health issues such as headaches or brain tumors.
Radiation for the use of mobile phones:
Radiation is an electrical and magnetic energy combination that travels at the speed of light through space also known as electromagnetic radiation (EMR).
Ionizing radiation (IR) – which can cause changes in the body’s atoms or molecules that can cause tissue damage such as cancer.
Non-ionizing radiation (NIR)–not causing these changes, but prompting the vibration of molecules. This can result in temperature increases as well as other effects. For instance, ultraviolet sunlight radiation, visible light, light bulbs, infrared radiation, microwave and radiofrequency energy are examples of NIR.
Small text and bright screens may strain the eyes of users of mobile phones. Since smart phones, mobile, ipads and other mobile phones for seniors are intended for short range reading, the eyes of users must continuously refocus and realign to process on-screen visuals and text.
Precautions to reduce exposure to mobile phones:
We can prevent mobile phone radiations by taking some good steps;
-Selecting a cell phone model with a low particular absorption rate (SAR) referring to the amount of RF radiation consumed by body tissue
-using a landline phone if you have one
– phone calls are kept short
-Be careful that claims that RF radiation exposure can be decreased by sensitive devices or’ shields’–there is no evidence to show that these devices work. They can actually boost RF radiation because the phone will immediately increase its RF output to fight the shield’s impacts to get the best communication level.
