Demo video Smoke & Fume Absorber A Long History The ancient Egyptians produced lead and other important metals like gold and silver as early as 5000 BC. In the Roman era, lead was used for coinage, jewelry and other everyday items including the production of Lead pipes for the transportation of water. Remarkably, many of […]

The ZIFduino, for all intents and purposes, is an Arduino with a ZIF socket. It’s geared toward those that want to do prototyping on the platform, but then move the ATMega chip to a stand-alone environment. The pin layouts are exactly the same, so it should be compatible with most shields designed for the Arduino.

Not long ago the Atmel company came out with a great tool for use with the AVR line of microcontrollers called the AVR Dragon. This small USB device provides professionals and hobbyists alike the ability to use: In System Programming (ISP), JTAG, Debug Wire, and High Voltage Programming. Unfortunately the device itself doesn’t include all
This is a fun speaker timer I made for some upcoming conferences. It uses a 4-digit charlieplexed LED (pseudo 7-segment) display and is driven by a AVR ATMega328 or an Arduino. It allows a default time to be set, can be paused, and will put out 5 Volts on several IO lines when 10, 5,

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,
