You might have noticed the Slaveflash I built with an Attiny 24, the instructable can be found here: Slaveflash-trigger-for-digital-with-Attiny24 After building the first prototype I collected all my old flashes I got over the years and had four more slaveflash-triggers to built. I already figured out an PCB-Layout for the SOIC-version of the attiny 24. […]

This is the last one of my ‘Things that make life easier’ series, I published in the last few days. It’s very simple, but most of the time the simple things are the most helpful. I always used the big 10 pin jack for programming my AVRs because my programmer also had the 10pin jack.

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 radius of the top is achieved by

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

This instructable will show you how to read the number on a binary pushwheel or thumbwheel switch using LED’s or an AVR microcontroller (I’m using an ATmega328p but this can be adapted for any AVR or probably another microcontroller of your choice). Multiple thumbwheel switches can be strung together to make an electronic combination lock,

This instructable will show you how to make a thermometer that displays the temperature of the air. It’s not the most accurate thermometer in the world, but for this price and the fact that it was homemade… This instructable will show you how to make a thermometer that displays the temperature of the air. It’s

The Arduino — and AVRs in general — have a wide range of power supply options ranging from around 1.8V to 5.5V. The choice of voltage is usually determined by the desired clock speed or power consumption requirements. The Arduino and its many variants have power jacks that allow connections from big, clunky “wall warts.”
