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 […]

My last visit to the dentist convinced me that I should really brush my teeth at least two minutes. I decided to build a special toothbrush timer: it would detect when a brush is taken out, measure two minutes and notify when the time is up. I chose to use Atmega328p, a weight sensor, brass cups,

In this Instructable, I cover modding the store-bought Deluxe Identity Disc to an upgraded version with 64 leds, controlled by an AVR MCU. The upgraded version is costume-ready and would be an excellent addition to your Tron costume – it’ll also look great on your desk/dresser/etc. My 7 year old daughter watched Tron:Legacy with me

Ever wanted a robotic liquor server?I purchased a Lynxmotion robotic arm last year and an Arduino (deci) to play around with. I had it serial controlled with a joystick and it was a great way to start in robotics. More recently I wanted to take on another micro-controller related project for a university science fair.

This tutorial will show you how to build a jacket with turn signals that will let people know where you’re headed when you’re on your bike. We’ll use conductive thread and sewable electronics so your jacket will be soft and wearable and washable when you’re done. Enjoy! A version of this tutorial is also on

Shift registers are a very important part of digital logic, they act as glue in between the parallel and serial worlds. They reduce wire counts, pin use and even help take load off of your cpu by being able to store their data. They come in different sizes, with different models for different uses, and

The Siemens DLO7135 Dot matrix LED is one amazing piece of optoelectronics. It’s billed as a 5×7 Dot Matrix Intelligent Display (r) with Memory/Decoder/Driver. Along with that memory, it’s got a 96-character ASCII display set with upper and lower case characters, a built-in character generator and multiplexer, four levels of light intensity, and it all

A while back I saw an EMF (Electromagnetic Field) Detector at makezine.com that used a led bargraph. I decided to modify it to use a 7-Segment LED Display! Here’s my project. Sorry I don’t have any pictures of it in use. Hopefully I can post some soon. Credit goes to Aaron ALAI for the original

Or, an exercise in input and output multiplexing, and working with bits. And a submission for the Arduino contest. This is an implementation of a tic tac toe game using a 3×3 array of bicoloured LEDs for a display, a simple resistive touchpad, and an Arduino to tie everything together. To see how it works,
