The Tuxgraphics AVR NTP clock using ATmega168

The Network Time Protocol (NTP) has revolutionized the world. Suddenly one could have anywhere in the world accurate time and date. NTP is a simple UDP based protocol and can be implemented in a Microcontroller. Using the tuxgraphics ethernet board and a LCD display we build a nice clock which gets time and date via […]

Printed circuit board 'Multiuse tiny1' using ATmega8

Project overview This small PCB, which I named Multiuse tiny1 was originally designed to convert NES/SNES controllers to USB. Since there is not a lot of space availabe inside an SNES controller, I designed the PCB to be as small as necessary. The PCB has improved since the beginning, thanks to the many other uses

The Prototino™ using ATmega168 microcontroller

What is a Prototino™?   The Prototino™ is an Arduino clone with a built in prototyping area.   Designed to make a permanent version of your project once you have perfected it on a breadboard but without the expense of embedding your original Arduino into your project. The Prototino also makes your project more reliable

The Game of Life using ATtiny2313 microcontroller

The reason for making this project is that I was always fascinated by Conways Game of Life. It’s a great demonstration of the fact that simple things with a very simple set of rules can do wonderful things: spawn more of them, modify themselves, do logical operations, even create Turing machines. I suspect much more
