Cambridge design consultancy Plextek has re-created two GaAs ICs for a US company with an obsolescence issue. The chips, described only as “GaAs control ICs”, were being dropped by their original manufacturer. “I suspect they are obsolete because of the MESFET process no-longer being available,” Plextek director of RF integration Liam Devlin told EW. “The […]
By Marcel’s Workshop I spend a lot of time on Genealogy with subscriptions to many services.To make it efficient I copy, paste and refresh pages often from one database to another.I use 3 monitors so I can go from screen to screen to compare data, all while evaluating what I’m looking at.While doing this I […]
This is a keystroke injection device (also called badusb). It is similar to a well-known USB rubber ducky made by hak5, but has much extended functionality, lower price and is also completely open source. It looks and feels like an ordinary USB flash drive, but acts as a keyboard that types in a preprogrammed payload. This payload […]
Here is an easy(enough) project to introduce you to the Arduino microcontroller, as well as Processing. This is my first Arduino and Processing project and I didn’t have too much bother getting it working. This is my entry to the Sparkfun Microcontroller contest so if you think it’s good, please vote!!(voting starts the 14th feb). […]
These are the RFID readers I used. http://www.parallax.com/product/32390 Taking a snack brake while prototyping. 🙂 I think this code works, but I can’t seem to find the last version I made. AND YES I KNOW THE CODE IS REDUNDANT, I was just trying to make it work, I didn’t care how pretty it was. #include […]
The Adafruit Feather nRF52832 has a BLE (Bluetooth Low Energy) functionality that has a lot of potential to be used in many different projects. In this Instructable, I will be stepping through a project where I created an iOS application that would receive data sent from the Feather and graph it. Just a few things […]
Advantech, a leading embedded computing provider announces its latest fanless embedded system EPC-U2117. The palm-sized system uses the latest Intel® Atom® E3900 processor technology to give a 30% CPU performance enhancement and a 45% graphic performance boost. EPC-U2117 is designed with dual display output, multiple I/O, and wide range 12-24V DC power inputs, which target smart […]
I originally started this project because I wanted to recreate the scene in the movie the Close Encounters of the Third Kind where the humans are communicating with the Mothership via a huge color organ. So I glued various bits of software together and made some prototypes and before I knew it I was talking […]
If you’ve always wondered what makes your favorite devices tick, then it may be worth getting down and dirty with electronics. The idea of tinkering with circuits and wires is understandably intimidating for beginners, but there are many resources out there that teach you the basics of electricity and physical computing under the guise of fun, hands-on […]
This example shows you how to read analog input from the physical world using a potentiometer. A potentiometer is a simple mechanical device that provides a varying amount of resistance when its shaft is turned. By passing voltage through a potentiometer and into an analog input on your Arduino, it is possible to measure the amount of […]
