This is a simple USB temperature probe that uses the AVR USB library by Objective Development ( It is in large part built upon the EasyLogger example by Christian Starkjohann. Whereas EasyLogger would send the data values over a keyboard interface, this project uses a custom device class and reads values using the ruby-usb library.

This invention is not so new but so I took the liberty of posting my symple version, based on IC 4093. With that, I hope no one more is surprised by the lack of water in the water tank, just as I was.

This project shows how to create an MB Electronics Simon game clone using an 8-pin PIC12F683 microcontroller. The game includes a full emulation of the original Simon ‘game 1′ and the ability to select from 4 skill levels which control the number of colours you must repeat in a sequence in order to win the game.

Jeri (with an I) is back with a new amazing video. This time, she was asked to design a circuit to trigger “artistic” events, when someone approaches. The device had to be inexpensive and small. So Jeri used a PIR sensor to do the job. Watch the following video to see her explaining how these sensors operate and also how can someone use them in a circuit to detect the infrared radiation of our body heat.
