    If you do make this a full ible, you should mention that you used a peltier unit instead of a PN junction. Just so viewers can understand what they're looking at. And if you use a PC, make sure the port will allow you to pull all 500mA. You can either add pullup resistors to the data lines to simulate a PC connection, or use a self powered hub. which can provide much more that 500mA in some cases.
