IR Receiver

Notes:

Q1 is a NPN Photo transistor that responds to IR. Q2,3 and 4 are 2N2222 transistors. High-Z headphones should be connected to the output of the transformer state at PHONEJACK1. This project is to be use with the IR Transmitter listen on the schematics page. It can also be used to listen to IR remote controls (i.e. TV Remotes) and natural IR (the sun, etc.) . Adding a lense to Q1 will increase the range of this device, but alignment will be dificult at best..

If you build this one, let me know at NJ95K@HOTMAIL.COM. I would love to know how it went and will place any info you have on this page. Thanks!
