[sdiy] frequency counter

[Gerard]

Hi David,

I built mine 15 years ago, it goes from a few Hz to 1.3GHz.
Nowadays, if you really want something simple, you might want to try a 
PIC or AVR design these only use a few components:
Using LCD display (these go for 4€/±5US$ in NL)

Or with 7 segment display:

Using AVR; http://www.myplace.nu/avr/

Regards, Gerard
