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 a fan […]

This Instructable will walk you through the steps needed to make a stained glass pendant with anLED that blinks in a pattern using a microcontroller. The blink pattern is an actual firefly song of a type of Japanese firefly. It is a scaled down version of the Jar of Fireflies code that my partner wrote. I have

The Swiss AVR Knife bundles a number of AVR programming projects together in a single convenient Altoids Gum Tin. Because of the flexibility afforded by microcontroller programming, it also provides a starting point for any number of projects based on LEDs and sound output. The SAK can contain as many programs as the 8K of memory permits and

There has been a lot of interest in muscle powered electronic devices, due in large part to the success of Perpetual Torch Perpetual Torch, also known as battery-less LED torch. The battery-less torch consists of a voltage generator to power the LEDs, an electronic circuit to condition and store the voltage produced by the voltage generator and high efficiency white LEDs.

The game Mastermind has been around a long time, and I remember getting a board version with colored pegs when I was a kid. I love this game, as it is solvable simply by pure logic. One player (or a computer/microcontroller) chooses a sequence of colors from a pool of available colors and then the other player

As most guys I don’t tell my wife that “I love you” as often as I should, but this little gadget will at least improve that situation as bit. So by combining a nice box and some hardcore electronics nerdiness I’ve made a nice christmas gift for my wife. The LoveBox is a small box

This project uses green surface-mount LED’s along with an AVR ATTiny45 microcontroller to simulate the behavior of fireflies in a jar. https://youtu.be/UeL0LC2IgpQ (note: the firefly behavior in this video has been greatly sped up in order to be easier to represent in a short film. The default behavior has significantly more variance in its brightness and delay

When I ran across the Jar of Fireflies Instructable sometime this past summer, I knew I had to build it. Full credit to Keso for an excellent set of instructions! I wouldn’t have gotten to the point of developing the firefly behavior without such a solid base for building the hardware, as well as firmware to start it out with.

Gotta love microcontrollers.They do lots of stuff … you can find them in computer mice , traffic lights , toys , and almost all electronic devices nowadays. Well , this is a project that pushes an 8-bit ATMega32 microcontroller to the limits. As you guessed from the title , it is a game system. Here

Play a prank on your friends (enemies?) by hiding a high-pitched beeper which sounds off at random time intervals. This instructable uses minimal parts. All that is required is: battery microcontroller speaker Why don’t I just use a 555 timer chip? You certainly could. I like this method because: 1. The ability to beep at random intervals 2.
