Trying to build a cheap Arduino data glasses for everybody. It's working, and now it can even help to avoid accidents.

A big and heavy alarm clock made from an old tea can, a big red button and a few other parts.

Holiday is always a good reason to make something cool. This time I wanted to play with Pro Minis and an RTC module.

Nokia 5110 and Arduino mini make a great serial monitor that can easily be battery powered at 3 Volts.
