hello all,
first of all sorry for asking help in this project as it has been already asked .but i coudn't resist.i searched the forum lot of times but most of the tachometers are for CARS and they were not clear.i want to built one for my bike.i did a small search over net and found this ckt. **broken link removed**
this is exactly suited for me.
every thing is ok except the input for the circuit.its given coil -ve lead in the ckt.i know input for this ckt is pulses from the spark plug.but how to get them? can i directly connect the spark plug output to the ckt....this dosen't feel good to me,spark means thousands of volts.
iam stuk at this place.
