LCD demo kit - VSWR meter / Frequency counter

This project was designed to demonstrate the use of an inexpensive surplus LCD display, the kit contains just a backlit LCD display, programmed PIC16F818 and if available a 10MHz crystal.

Note - Firmware is now at version V2 which has much improved frequency counter accuracy, if you purchased the kit at Loughborough 2009 please post the PIC16F818 back to me and I will return another device programmed with the latest code. If you wish to have a go at programming it yourself the latest data is on this page along with a link to a suitable programmer. All kits purchased after October 2009 are OK.
