There are many universal remote controls out on the market. None of them have the style of a GameBoy Advance fitted with a little infrared transceiver and a functional C++ program. The name AIR comes from Advanced IR. It was published in the Make blog. Read more

This is a little HTTP Web server and a FTP file server. It is built around an 8bit AVR and a Wiznet LAN module. Once a year I get it out of the box and connect it just for the nostalgia and the delight, that it still works. Read more

This is an automatic video switch (AVS). With this device you can connect a DVD player, satelite receiver and a game console to your TV without repluging.

Sometimes when handling AVRs something happens that is known as "bricking" a device.

Using LED or character LCD displays is quite simple. However 7 segment LCD displays are very nice too and look just that bit more professional and use far less power.

My first attempt using an AVR together with the USB port. It's an HID keyboard device featuring a num lock LED and num lock key.

Sooner or later I had to make one of these. A binary clock.

I made these blinking hearts for my girlfriend.
