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.

PCB

P1:

1 - Reset

2 - GND

3 - Vcc

4 - SCK

5 - MISO

6 - MOSI

P2:

1 - Vcc

2 - GND

Infrared LEDs

The perfect LEDs aren't found till now. The SMD LEDs have a too big opening angel, 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.
