IMG_3951in this video the resistance of this bifilar coil is about 0.2 ohms. reed switch contacts wear out after 24+ hours non stop running on 2,5 volts. no good deal 😦






IMG_3849viena tokia – 3-4 val. darbo + stikline prakaito. dirbu balkone, apie 40 laipsniu silumos. nenoriu kambary nuodytis kliju garais. y diena, po viena (is viso reiks 32):IMG_3898

there will be two system coils:

system 1 (8 coils on the bottom + 8 coils on the top, all in series)

system 2 (8 coils on the bottom + 8 coils on the top, all in series)

I think resistance of the one system coils will be less 2 Ohms

there will be two reed switches and power supply less than 3 Volts, because of wearing out reed switches contacts.

electric schematic idea looks like this:





I checked ohms on 4.5 coils (another half 5th coils end is on the spool ). It’s about 0.5 ohms, 0.1 per coil, 0.8 ohms – eight coils . When I finish bottom coils I’ll try to run disc on its with 1 – 1.5 volts.

IMG_3954don’t worry I’m on the track. price for this  OU device will be 1 million $. not because of overunity but because of bloody sticky nasty wires. one day left 8]

IMG_3955yes it is 🙂  I think in a few days I’ll put there video how is running   this half of million $ device 😉

from first run I’m disappointed. 3.5V  – about 250 rpm. the fat reed switch keeping too long closed contacts. I can’t adjust:

but I have too much room for improvement (+another half million$ 😉 ). now I’m trying to play with small reeds. they are more adjustable for closed contacts time. or after this I’ll go to transistors, more complicated setups.


it’s still not OU because of  silly test with silly crap reeds and batteries. one battery wasn’t  dropping voltage for about  1 hour but I’m not sure if the reed sw. was working correctly. another battery is dropping voltage much faster doesn’t matter if battery’s places is changed between them.


my next test will be with bridge rectifiers from shotky diods. I’ll put the video with results.IMG_3960

will be updated. I heave some  idea to use low esr capacitors to shorten pulse from reed switch. just don’t know when.

there is my idea how to shorten pulses of red switch by small supercaps by charging them trough the motor coils and discharging back trough transformers low ohmic  coil.IMG_0227
