GuGaplexing is a new LED display multiplexing technique. Compared to Charlieplexing, GuGaplexing allows you to control twice as many LEDs, with just a few additional components. GuGaplexed Valentine LED Heart project has 40 LEDs arranged in an ‘Arrow Piercing a Heart” arrangement using only 5 pins of a microcontroller. The project uses an AVR ATTiny13V […]

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

With Google announcing the launch of Voice Search for desktop, we couldn’t help thinking that there was even more fun to be had with talking to a computer. So, we went ahead and built an open source dev board to inspire people to build their own useful and wacky contraptions to take Voice Search to

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,

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.
