TVBGone/en

TVbgone with two SMD LEDs and two normal 5mm LEDs

This is a clone of the normal TVBGone Kit. TVBGone is a board, that tries to switch off every TV device. This one is build with almost only SMD parts, this board is smaller than the original.

Infrared LEDs

The perfect LEDs aren't found till now. The SMD LEDs have a too big opening angle, so the power is not enough for switching the TV off. On the other hand with 10° you have to target very perfectly... Another problem is that the board haas a bug for the SMD LEDs, if these are solded, they can create a short circuit, but this will be fixed for the next version.
