At the moment I do not have a kitchen timer. Not because I do not want one, (they’re cheap enough to buy) but because it seems impossible to buy a kitchen timer with a decent user interface. That means I have to build my own, which I just the kind of stuff I like. The […]

Beamer Control: Schematic Source code I made this project for Henk. He has a beamer for watching movies and a motor controlled screen. The purpose of this project is very simple. If he turns his beamer on, the screen must to down. And if the beamer turns of, the screen must go up again. This

Door Opener: Schematic Source code I made this little project for Hans, yet another brother of mine. (I have 5 brothers.) He had a garage door to control and bought a little RF transmitter and receiver to control his door. Leo made a nice cabinet with relays to control the 400V 800VA motor. They turned

Dimmer: Schematic Source code I made this project for Leo, a brother of mine. We had an old remote control of a video recorder laying around and he wanted some dimmers for all the lights in his house. I didn’t have much experience with programming microcontrollers at that time but I was willing to start

This project describes an automatic light system for kitchen sink where you need sufficient light to properly clean your dishes and vegetables. It uses an ATTiny84 microcontroller with a PIR motion sensor. When motion is detected, the microcontroller turns on the light. The light source consists of 10 bright white LEDs that are driven by

There are numerous posts on Instructables about how to make a flickering LED candle. This is my version. The project requires the following components: 1. Tiny45 AVR Microcontroller (Tiny13 would also do) 2. 1W Warm white (or yellow) LED 3. Perspex tube 4. AA or AAA size batteries- 4 (alkaline or NiMH) 5. PCB stock

I’ve been meaning to make something cool for my dorm room this coming semester and decided that some custom closet lights would look great. In this Instructable, I’ll show you how to make some nice-looking LED lights that will turn on automatically using a hall effect sensor and a magnet. Edit: I’ve noticed a lot

Who wants to go outside to see if the mail has arrived? In the cold winter or rain Iâd rather not have to put on a jacket and shoes, only to find that there was no mail. This project will notify you of the mail carrierâs visit, and as a secondary function it will remind

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