The receiver is simply the LCD display example in the picbasic pro manual, with a 4MHz crystal and uses 4 data lines to the LCD. The serial input is on pin 10. The transmitter is a 16F84 with 4MHz xtal, pull up resistor on MCLR and the serial output on pin 10. Power for both modules is a battery pack and 7805 regulator.
I am thinking of replacig the wire linking the tx to the rx with one of those 433MHz tx/rx modules so I can use the display remotely.
