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

I made this project as a side quest for a company. It was used in the production for fast and reliable testing at the end of line.  Read more

A nother commom issue is timekeeping. This little module contains a DS3231 (or DS3232 with RAM) and the backup battery. Read more

Measuring current in a design used to be a bit tricky. But with modern semiconductors this is no more effort than a tiny module with an I2C bus. It only needs three resistors and two capacitors. I used this IC in the Read more

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. Read more

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

This is a micro Tetris. It features a fully functional Tetris programmed in C with the free TI Code Composer Studio. Read more

This project is a small board containing a CPLD and a SRAM IC. It has an SPI interface to utilize the SRAM. The CPLD is used to implement the SPI interface and address the SRAM. Read more
