One basic need of a computer scientist is to measure the power that a USB device drains off the PC. This device is plugged between the PC and a USB device and displays the current on an LCD.

After I had a little misshap with my Saleae Logic that ruined the analyzer and parts of my PC it was clear that some galvanic protection needed to be implemented. This ultra compact device plugs directly in the Saleae 8bit Logic and galvanicaly insulates it from the testcircuit.

This is a little Tetris game. It is built with a Nokia 5110 cellphone LCD and a Texas Instruments MSP430G2553 microcontroller. The system without the backlight uses less than 1mA. It is written in C++ with the TI Code Composer Studio.

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++ programm.
