Hi All of you EE and electronic buffs:
I have an older tachometer I would like to alter it to read higher values. As it is now, it reads 2,400 and 12,000 rpms. I would like to perhaps double those readings.
This is a hand held tach that has a photo cell to read light pulses. It has an analog meter to give the readings. The instructions in the case says that one puts reflective tape on the object to be tested. Could I also increase the sensitivity with a better photo cell? The meter has a pc board and is all solid state so it can't be too old. It was manufactured by The Pioneer Electric and Research Corp Foresrt Park, Illinois
As a gadget guru, I would like to get this thing working.
Anybody out there have any suggestion, or would like to play with this thing?
Stay well,
Franchi
