Turn your USB wi-fi dongle into a satellite dish
Turn a case fan into a personal cooler
Another classic, the USB casefan cooler mod turns an old PC casefan into a simple USB-powered desk fan. We could tell you all about how to make one out of an old USB cable, a case fan, and a coat hanger, but we'd rather just link to our full writeup .
