Hello All,

Back in issue No. 147 of MEW Mike Crossfield wrote an article describing a low cost rev-counter. He used a discs with 60 slots (or the 60 tooth Myford Super 7 bull wheel) to generate 60 pulses per revolution which directly read off as a frequency. Is there a device or a circuit incorporating such a device to allow one pick up ber revolution to be amplified exactly 60 times?

Regards,

Wychwar
