a majior newbie here  please help. when i see the symbol  on schematics, with the vr A jumped from one side of the three poles, is that what i means  or is that a special v resistor?

thanks, peace out,
joe

Variable resitors generally have three poles...Just wire them the way
that is shown in the schematic.

ok  thanks mscoffman,  that is what i thought  but i needed confirmation.   thank you again over and over again to infinity, and beyond.  (big grin)
peace out,
joe

Forgive me for my impatience as I have not managed to read the entire tread, yet, but have you managed to continually run a motor with a load (air resistance and friction is a load) without loosing voltage on your drive battery/capacitor?

If you have, then I bow to you Jesus

There is a problem with resonance unsolved.
The circuit used to run well a long time then it suddenly began to discharge the battery.
Replicators of the circuit reported that the problem was the resonance.

It was explained that the resonance changed when the battery had a different higher value on voltage after running awhile.
The resonance affected by the voltage changes caused the circuit to misbehave and adjustments were needed every now and then to keep the motor running in resonance.

Then comes a greenish mold or rust and damage the soldered connections and the motor stops without apparent reason.
When you check continuity the rust has damaged the connections... etc.

A way to keep the rust out of the connections and to keep the resonance constant is needed.

Oh, that sounds really odd....
Greenish mold you say, makes me wonder if it is the same stuff I get on my battery when I charge it... Also it could just be copper oxidation, which basically is a form of green rust on copper.

I wish you the best of luck in trying to work out this problem...
