Open source color video game development system based on AVR

This project describes an open source color game development platform based on an AVR microcontroller. You can code a color, high resolution, smooth video game, like Super Mario Bros or Commander Keen on this system. All video processing is done by software in background using interrupts, with no external active components. You only need to connect the AVR to a RGB monitor. AVRs don’t have enough RAM for di ...

AVR based remote controlled fan regulator

This project is from Extreme Electronics that describes an AVR-based (Atmega8) remotely controlled fan regulator. The control commands are received through a DVD player remote control. With three buttons on the remote control, you can turn the fan On and Off and also conotrol the speed. You can also purchase the PCB for this project too. For more detail: AVR based remote controlled fan regulator ...

$10 ATtiny85/45 POV display!! (works really well)

Hey guys! This is an Instructable for making your own ATtiny85/45 5 LED POV (Persistence Of Vision) display! This is my second Instructable, also for the Elemental LED contest, so drop a comment and vote it up! The total parts cost for this POV display is under $10! (If you get the parts from a wholesale supplier, like Mouser or Digi-Key) I apologize for all the horribly blurry pictures, I'm using my iPod t ...

$1.50 Arduino TV Annoyer!! (Turns TVs on when you want them off) using microcontroller

Hey Arduino fans! Here is an 'ible for making a device that turns TVs on when you want them off, and off then you want them on! If you hide it in something inconspicuous, it would make a great April Fools joke or gag gift. And the best part is that the total parts cost is less than $1.50!! (Assuming that you already have an Arduino and the tools) This is a contest entry for the LED Contest with Elemental LE ...

Turn a TV-B-Gone into a super camera remote!

Intro: My Nikon DSLR has an infrared remote function (remote sold separately) that is really handy, but fairly limited in range. A while ago, I bought a TV-B-Gone Kit from it's inventor Mitch Altman, and it can turn TV's off from a great distance. I thought, "Hey, this thing is open source! I can hack this!" So follow along for replacing the firmware to create a super-powerful camera remote. You could even ...

Laser Tripwire takes a Photo, Uploads it to Twitter

This instructable will show you how to construct a laser tripwire that can twitter and grab an image from a webcam, as well as execute any command you can put in a bash script. This instructable is actually quite simple and is even suitable as a beginner arduino project. It requires a GNU/linux (or possibly Mac) operating system with the arduino IDE and Processing IDE working properly. This project could al ...
