The PIC based Infrared receiver can be used to control your PC with any remote that you have (TV, VCR, CD or Stereo). The component used by project is very simple, minimal version uses only 3 components : PIC16C84, SFH 506 (infrared receiver sensor) and 5V1 zener.
But for safety, it’s recommended that you replace 5v1 zener with 78L05 regulator. Original hardware and software was designed by Martinus and Ties Bos and has been improved by Srdan Milostic. You can use almost ANY Microchip PIC microcontroller, but firmware only available for PIC12C508/509 (512B/1024B OTP) and PIC16C84/F84 (1K FLASH, C84 is old version).
