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 […]

Last year I modified a blue LED fan with RGB LED’s to enhance the look of my server case. Last summer I built a gaming computer and ever since I wanted to light it up with multiple controlled lights and fans. I finally figured out an easy interface and designed a simple network (the “fan

Microcontrollers (MCUs) are fantastic little ICs that give an extra element of versatility to your electronics, robotics or other project. But they’re really not much use on their own. To function, all MCUs need some sort of support components, and a board to live on — one example of course being the famous Arduino. These

After testing many systems development for PIC and AVR microcontrollers, none satisfy me. So I created this system with breadboard that has satisfied me. Step 1: More space free In this development system, I put two protoboards turned 180 degrees from each other. The space that is left to just enough space to insert a

after making a usbtiny isp programmer and using it for 6 months, i was looking at making another one for carrying around. i like the simplicy of the usbtiny isp design but would like to make it even smaller and take less parts. one thing in the original design that i want to change is

video Direction Aware Messaging LED Spin Top We recently built a LED spinning top with message display. Its an improved version of a similar top published by Elektor in their December 2008 issue. The Elektor top can be spun only in one direction. The synchronization required to print message on the LEDs arranged along the

Some of the fruit and vegetables we eat can be used to make electricity. The electrolytes in many fruit and vegetables, together with electrodes made of various metals can be used to make primary cells. One of the most easily available vegetable, the ubiquitous lemon can be used to make a fruit cell together with

video Fire-free LED Matchstick I just completed a new project: a fire-free and fire-safe LED matchstick. To light this matchstick you strike it against a normal matchbox filled with neodymium magnets. The LED matchstick has an inductive sensor that detects the magnetic field as you strike the matchstick against the matchbox and it lights up

With a single LED you can indicate the state of something: on or off. That might be a little boring. With an array of LEDs you can display characters or even some simple blocky graphics. That might add a little pizzaz to a small microcontroller project. You could use individual LEDs wired into a grid

Inspired by various LED Throwies, blinking LEDs and similar instructables I wanted to do my version of an LED controlled by a microcontroller. The idea is to make the LED blinking sequence reprogrammable. This reprogramming can be done with light and shadow, e.g. you could use your flashlight. This is my first instructable, any comments
