Jarek tipped us with his latest project, an E-paper screen shield kit for Teensy. He writes: E-paper screens have been hacked out of Kindles and store price tags for a while, but this is the first ( to my knowledge ) open-source project which offers a simple and cheap interface for...

Ham radio is the use of radio frequency spectrum for purposes of non-commercial exchange of messages, wireless experimentation, self-training, etc. Developing a ham radio project may requires using an antenna analyser, a device that is used for measuring input frequency and...

"Tau" is a new board in the world of embedded systems, designed by Rabid Prototypes.  It is powered by a 32-bit ARM core, but Tau's main strength is full compatibility with the well-known Arduino Zero,  yet in a very tiny package. What is the Tau? The Tau is an extremely...

The DIPFORTy1 is a powerful Xilinx based FPGA board with small form factor and many programmable I/Os. It is popular for its high performance at most competitive price. Introduction: The TE0722 is based on the Xilinx Zynq-7000, a System on Chip. It contains a FPGA and a Dual Core...

Hi! Today I'll explain you how to recover your bricked ATtiny microcontroller using your Arduino board. ATtinys are very popular due to their small form factor yet very powerful. While working with them you may accidentally brick the ATtiny. As arduino is extremely popular and really...

Paweł Spychalski build a photoresistor based daylight meter sensor connected via I2C bus using ATtiny85: I love AVR ATtinyx5 series microcontrollers. They are cheap, easy to use, they can be programmed just like Arduinos and comparing to their size they offer great features. For...

rik @ riktronics.wordpress.com show us how to program AVR microcontrollers using an Arduino board. Advanced hobbyists like me (and you, of course 😉) love to play with microcontroller. And the most famous microcontrollers for beginners are AVR series from Atmel™.  Almost...

Dziku discuss how to configure a cheap 433MHz wireless module for serial communication: HC-12 are cheap 433MHz wireless serial port communication modules with a range up to 1800m in open space. Each costs about $5 when bought from China, and 2 of them can create wireless UART link...
