A project log for Micro TV-B-Gone

The Micro TV-B-Gone is based off of Adafruit's original TV-B-Gone kit, except made to be as small as possible, using an LIR-2032 coin cell.

Improvements for future iterations

In the future, I would like to add a battery life indicator light to let the user know when the battery is nearing the end of its life. Currently I just keep a mental note of how many times I've used it, and double check with a multimeter. 

I would also like to remove the two caps from the bottom of the board, as they are scarily close to shorting out from the coin cell. By removing the 3 unpopulated IR emitters on the top, I can make room for this and the battery life indicator.

The final improvement would be to build the battery charging circuit into the board, and add a micro-usb connector so you don't have to purchase an external LIR-2032 charger.
