Schematic

The schematic I used to build this is a slightly modified version of the one found on Ladyada`s site.

 

The Differences are:

- It only has 2 IR LEDs, as opposed to 4.

- The IR LEDs used are the High Power TSAL6100s.

- The resistor values were changed from 120ohm to 47ohm.

- A blue LED was used instead of red.

- 2N2222 transistors were instead of 2N3904s.
