Katja & Guido at Tuxgraphics sell a very affordable little AVR controlled power supply. That power supply can be controlled by sending it commands by I2C. Because I already have a pretty universal network connected to my PC it seems very logical to me to modify the software for that power supply to accept commands […]
An Atmega128 microcontroller has got 4K of built in static RAM, which is pretty enough for small and medium range projects that do not involve huge amount of data processing. But if you think you need more than that for your application, you can expand it by adding an external RAM chip. This article shows
If you are a computer technician and want to avoid the need of a PC on your desk to generate test rasters, this is something you need to build. This is an embedded monitor tester that you can use to test if a VGA monitor is working or not. You don’t need a bulky computer

There have been several Instructables dealing with outputs from the ATtiny2313 and similar AVR devices. For example, http://www.instructables.com/id/Ghetto-Programming%3a-Getting-started-with-AVR-micro/, http://www.instructables.com/id/Drive-a-Stepper-Motor-with-an-AVR-Microprocessor/. Working on the latest one from The Real Elliot, which showed how to control stepper motors, I found that it would be really helpful to be able to run alternate sections of code in the same

Have you played with Arduino’s and now have a taste for microcontrollers? Have you tried to go beyond Arduino but got stopped by the dense datasheets? This is the instructable for you! I was working on an instructable for the epilog contest which would wirelessly link two smoke alarms. I wrote all the code and

This instructable shows how to control a group of led’s with one microprocessor output. The micro I will be using is an Atmel Attiny2313. Step: 1 Parts and Tools Parts: Attiny2313 (got 5 free samples from Atmel) 20 pin socket Resistors (any size will work, depending on your setup. I will explain later) 5v regulator

Do you currently have an Arduino and want to make it smaller for cheap? The Quasi-duino is for you (Italian for almost-duino). This makes a functional “almost” Arduino, in a very small form factor using the narcoleptic library for pico-power operations on a pico-space breadboard. This ‘ible will use Arduino 1.0. All of your Arduino

I have seen plenty of Instructables showing how to work with microprocessors, but they all assume that you have worked with them before and know what you are doing. I have not seen an Instructable that takes you from nothing and builds on each step. What we will do here is to start with a

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
Duino tagger– General introduction Duino tag is a laser tag system based around the arduino. Finally a laser tag system that can be tweaked modded and hacked until you have the perfect laser tag system for office ordnance, woodland wars and suburban skirmishes. Laser tag is combat game like paintball or airsoft without the pain,
