Mini infrared remote

I had some space left on a panelized PCB I wanted to etch, so I decided to fill the remaining space with a small project I had in mind. The idea was to make a small infrared transmitter, controlled by a PIC microcontroller, that could run off a single lithium cell (CR2032).

LIRC transceiver

The image below shows the general purpose infrared-transceiver I’ve built to control all kinds of devices remotely with the help of a computer. It is fully compatible with LIRC and has a long operating range due to the power transistor and buffer capacitor. Another advantage of this design is the low-drop regulator
