Has anyone seen Lasersabers new motor runs on 1000uf cap

0.2mA yes of coursse    now you see why ou is possible ? just get the electricity by keeping cloe the generator coils..but ! you must have lenz-free coils

lenz-free coils? its a bit like saying i want a square balloon...

but you don't necessarily need a lenz free coil... lets say that for example that due to lenz law the draw increases 100 fold!

100 x .2mA = 20mA

out put  = 21mA

OU!

FYI! in case people are thinking i'm posting real figures, I AM NOT, just exercising my point.. that is all.

I'm sure lasersaber already checked it . My humble advice would to start with air core coils in parallel to tap power from it (less lenz drag). First one coil, adjust to the output voltage then place all around and try to charge another capacitor using fast Schottky diodes and watch how "juice" it can be squeezed out of this assembly without slowing down motor. Then the rest is obvious..

I am writing about this circuit http://www.overunity.com/13523/has-anyone-seen-lasersabers-new-motor-runs-on-1000uf-cap/msg363823/#msg363823 ( video http://www.youtube.com/watch?v=OqQSJjRJ6EQ )

@Magluvin:

No 2.2 nF cap: You probably have seen that the spikes (if the 2.2 nF cap is missing) are almost 16 V (1.5 V power supply to the circuit). This is interesting but not good for turning the rotor. The rotor turns without the 2.2 nF cap, but slower and is difficult to start. The circuit only works around 2 Volt supply Voltage. The rotor can not be started with a supply Voltage of 4 Volt or more.

2.2 nF cap in the circuit: With the 2.2 nF cap (which prohibits self oscillation according to my uneducated opinion) the circuit is switching cleanly and the motor runs nicely, also with higher Voltages (I tried up to 9 Volt, then the rotor starts to act crazy due to imbalance).

@Poit, forest:

1µA versus 200 µA: I am aware that Lasersaber is running his motors with 1 µA and I am trying to match that. So far I am a bit below 200 µA. The main reason for Lasersaber's low power draw is the 1600 Ohm DC resistance of each of his coils (very high impedance). The coils in my motor only have 90 Ohm DC resistance. But I already have coils from relays with 1600 Ohm DC resistance and I am on the way of building a motor with them. See my post http://www.overunity.com/13523/has-anyone-seen-lasersabers-new-motor-runs-on-1000uf-cap/msg363167/#msg363167 . The low power draw can for sure be achieved with the 1600 Ohm coils from relays, but the rotor may not turn with 1 µA due to the fact that it probably will be less precisely built and will have more friction than Lasersaber's motors.

About harvesting electricity with a generator coil: I see that already a little resistance can stop the rotor. It must be a really Lenz-free generator coil to achieve anything interesting. But I believe in having a very low power draw rotor before trying to harvest electricity with special generator coils. It must be easier to harvest µW instead of some Watts. Gently does it.

Remark on DadHav's two transistor circuit: It has some potential because it does not need a Reed switch (yes, I do not like Reed switches) or any other trigger component (like a Hall sensor or a separate trigger coil). The drive coils produce the trigger signal which is sensed by the PNP transistor (which then in turn switches the NPN transistor driving the coils). I am still playing with DadHav's circuit and want to make it work with a MOSFET, it intrigues me. I tried many transistors and resistor values but only the 2.2 nF cap lead to some success.

Hello Conrad, I'm really happy to see you guys using the little circuits. As you know I can't take 100% credit for the idea. The simple circuit is in some of the self start circuits like SmartCreations and a few other have videos of. I agree with you on the LaserSaber motor. Very high impedance, large diameter rotor with strong magnets and almost no friction. Don't forget the the slow RPM's and pulse rate. I didn't pay a lot of attention but how did LS measure the slow frequency pulses. He couldn't have used a meter or did he? The double circuit is a very different story with some interesting output results as you might have noticed on the video. It would really make me happy to see you guys make some improvements and have some fun with something a little different than what we've been doing. The circuit is in the most basic form and needs adjustment for sure. If you notice the very interesting aspect of how it ran the model airplane motor it might show some potential. The down side of the circuit as it would pertain to a motor having some torque is that if you load the shaft and slow the motor you also loose the bias on the driver transistor and in turn the power transistor gives in to the load rather than try to power through the slow down right? Anyway guys I hope you don't mind me hanging around a little bit to see how you're doing. I've thought about making a motor like LaserSaber's just because I think it's really cool and it could be made to be a kinetic work of art. BUT, I've had my motors to the point where adding only a few RPM's charges instead of discharges the capacitor many times, it's on one of my videos. Getting the little extra you need has to come from Unobtania or Unobtainium. Ha, even if the Unobtainium is a Lenz free coil. There has to be an answer somewhere once you get that close. Good talking to you guys.
