Re: Frequency counter, Pace MBT solder and extractor

I'm building a freq counter as a learning experience with PIC controllers.

http://204.210.50.240/techref/default.asp?from=/techref/microchip/../piclist
/&url=weedfreq.htm

There is a discussion that this is only accurate to 20 Mhz range when built
with a 16F84 pic but use of a non-flash pic can make it faster.

It will probably be udpated in the future. But 20 Mhz will cover me for now
(Pac Man has 6 Mhz signals).

One warning don't try to use an OPTIX 16x1 display as they are actually a
8x2 so now I'm stuck rewritting code....

What is the freq of that counter on E-bay?
