Having retired recently I am going thru my tons of toys/tools/junk trying to sort into sell, throw away, keep, ect.
I have a bunch of these little circuit boards with an electronic oscillator chip and a speaker and battery connector (std 9V) on them. I have used some for all kinds of applications requiring a oscillating AC signal/tone.
One thing I did was to use it as a device to tell when the mags points opened and closed when checking timing of the engine ignition on the airplane.
I got a batch of them REALLY cheap and was just figuring if I would be willing to send them to anyone that wanted one because of the time and effort required for packaging and shipping.
What it does is tells you the difference between points closed and open because it changes tone when across the coil verses across the closed points.
The fancy device for doing this is not all that expensive, but I'll put this in prospective by telling you I only paid $1.00 each for these, but I hate to throw them away.
Mind, you would have solder on two wires and a connector or some clips yourself (I don't want to start a business by doing that myself) but I am putting this out to see if anyone is interested in these things.
Well, enough, anyone think they could use such a thing, let me know. We could use 3rd class shipping and such to minimize cost ect.
