Pulse motor build off time.

@hoptoad: the plunger, if it does rotate as it goes up and down, is doing so because of mechanical effects, not any "magnetic vortex". However I don't think I see any rotation. The plunger shaft in my MescalMotor may occasionally rotate, due to the offcenter striking of the balls on the ends of the shafts, a mechanical effect similar to the way the camshaft will rotate the valve lifter bodies (as designed) by offcenter striking while an internal combustion engine is running.

Here's a scopeshot of the raw piezo output from the MescalMotor as shown in my video above, just for documentary purposes. This is with the FWB/Capacitor/greenLED load in place. The unloaded output has spikes that go over 9V. (18v p-p)

Thanks TK. I couldn't work out if their was a spiral groove on the shaft or it was just the springs that made it look that way.

I don't know if Lasersaber is entering the pulse motor build off or not, but here's another great offering from him on YouTube.

It's interesting, isn't it, that he can use a DMM as a voltmeter to get a voltage reading, then simply change the switch setting and get a current reading, without changing any wiring connections. I sure wish I had a DMM that worked that way, it would save a lot of trouble.

LOL. - As usual, in my Over exhUberance, I didn't notice the little details !
