USB Thermometer
While we are on the topic of USB devices, I happen to come across an interesting USB project which is a thermometer, pressure-sensor and relative humidity sensor dubbed the USBTenki. The device is made using a MCP9803 sensor for temperature or a Sensirion SHT75 sensor for temperature and humidity.
The tutorial comes complete with a full set of schematics, hardware list and firmware. This seems like the perfect little project to get back into the lab. Check it out yourself http://www.raphnet.net/electronique/usbtenki/index_en.php
