[CADCAD_CAM_EDM_DRO] RPM Meter

If any is interested I posted a simple design for a 4 digit RPM meter at
my web site. It uses an optical sensor and a PIC Microcontroller.

The entire design can be built for about $20.- . If anyone needs to PCB
layout files and HEX code let me know. However a PCB is not needed as
it's such a simple design it could be wired on a perf-board.
