Ever wanted to be “logged in” to your AVR microcontroller? Ever thought it would be cool to “cat” a register to see its contents? Have you always wanted a way to power up and power down individual peripheral sub-systems of your AVR or Arduino in *real time* ? Me, too, so I wrote the AVR […]

Introduction Ever fancied building your own camera controller? IMPORTANT NOTE: Capacitors for the MAX619 are 470n or 0.47u. The schematic is correct, but the component list was wrong – updated. This is an entry into the Digital Days competition so if you find it useful, please rate/vote/comment favourably! If you reallly like it and are a stumbler,
You know it, in the winter time it is hard to get up, because it is dark outside and your body just won’t wake up in the middle of the night. So you can buy an alarm-clock that wakes you up with light. These devices are not as expensive as few years ago, but most

Microprocessors are so cheap these days. If only there were a way to program them up just as cheaply… *wavy dream-sequence lines* In this instructable, find out how to build up a complete AVR microprocessor toolchain: compiler, programmer software, programmer hardware, and some simple demos to get your feet wet. From there, it’s just a

Do you know this classic wooden labyrinth game with two knobs for X and Y rotation? So, I’ve decided to modify one by connecting two standard servos to the knobs and let a microcontroller (ATmega32) play the game. Credits: – To CarlS www.instructables.com/id/Servo-Controlled-Marble-Maze/ for inspiration. – To the AVR freaks www.avrfreaks.net especially Dean (aka abcminiuser)

We’ve all seen LED fans that you can put in your computer to make it look cool. They usually come in blue, sometimes red or green and consist of a basic PC fan with 4 bright LED’s mounted in the 4 corners. They source their voltage from the fan’s power input, so if you’re using

This instructable walks you through programming and using the Boston Android Xmega evaluation board to work as a simple arbitrary waveform generator taking advantage of the integrated 12bit DAC and high speed DMA controller. I have provided precompiled firmware as well as source code which can be loaded onto the device and configured via a

This is merely an instructable to explain how this device operates. I hope everything is not too obfuscated. This prototype consists of three 8×8” modules. Each module operates independently of each other. Each module consists of 4 “pixels”. Each pixel is 4 inches square and consists of 21 LEDs, two IR emitting diodes, and two
