i built this circuit last nite. http://www.simplecircuitdiagram.com...your-digital-voltmeter-to-inductance-meter/ i was just wondering if it is possible to modify the circuit to increase the range of it? if possible what would i have to change? TY
What does this have to do with the OP project? If you are really interested you need to start a new thread, I don't see any connection here.Inductance or the induced Voltage as a magnet passes a Ferrite core with wire wrapped around the core.
So if the Rpm is slow, the Scope would see one sine wave, if the Rpm is much quicker, the sine wave would be shorter in amplitude and shorter in pulse width. IMHO!
So the faster the Rpm, or frequency, the less Voltage the Scope would see at the output of the inductor.
Thats how I see it...am I even close?
