  • Good !

  • What kind of generator is that?

  • @rocketman221projects It's a Dirod, of the basic Moore design with some TK mods. It can reach 60 kV on a dry day.

  • so how many rpms..

    and.. have you tried magnets on this???

  • @josephdupont I've measured over 12000 rpm on this motor and much faster on others. The currents that electrostatic machines produce are so low that their associated magnetic fields are very weak. They can be detected, but they aren't really useful in interacting with permanent magnets. So sure, I tried magnets in various ways but I never noticed any special effects from them.

  • How did you make the generator?

  • @TheLangfords I gnawed it out of plastic and brass and aluminum with my bare teeth.

    Just kidding! I used a lathe. The Moore's Dirod electrostatic generator general design is available on the internet in many places. If you compare my Dirod with the published designs you will see a few differences; they aren't really significant, except that carbon fiber makes better brushes than anything else I've used or seen tried by others.

  • @TinselKoala Cool, thanks for answering.

    (have you seen Instructables-dot-com? This would go down a storm there.)

  • Very impressive little motor. What is the rotor made out of?

  • Finally!! Free Energy!!! (I didn't pay for anything :) )

  • Other hand in the pocket.

  • Yep, always. Except when stupid.

    I have gotten a very strong conditioned reflex.

    I can't touch these things with both hands. Except when stupid, or when someone's watching.

    What's really "Funny" is when my bodycharge discharges through the soles of my shoes into the concrete floor.

    OUCH!

  • Heck, that was only 10 kV or so. Better than a Venti Espresso from Starbuck's, and cheaper too.

  • @TinselKoala bud did you see the battery of capacitors on the generator?

  • @AKAtheA

    Sure... I put them there.

    For the motor demo I had them out of the circuit, but then I put them in (the fiddling with the knobs) for the NE-2 demo... and that's why I got shocked, the 400pf or so at 30kV packs a bit of a jolt.

  • @TinselKoala so many caps & only 400pf? That would be 0.198J @ 30kV, not very much...

  • @AKAtheA

    Yep. The caps are 400 pF 30 kV doorknob transmitter caps, basically just a solid chunk of barium or strontium titanate with electrodes and insulation. They are in 3s-3p stack, so if I did the math right that still gives 400 pF but raises the standoff voltage to 90 kV, nicely above the max voltage of the Dirod. But I have seen it spark across the stack on occasion... dust or hair maybe.

    It's enough to startle -- as you see -- but not to kill. 15 J across the chest....maybe different.

  • @TinselKoala

    Sorry, correction, the caps were IN for the motor demo and after I zapped myself I took them OUT for the NE-2 demo, to get dimmer but more frequent flashes.

  • ouuuch the lights even blinked :-)

  • Great combonation of a Dirod Electrostatic Generator, Corona Motor, Flashing Lights, and being Bitten by a Spark... Excellent!
