Has anyone seen Lasersabers new motor runs on 1000uf cap

Conrad, would the moment of inertia of your rotor be more than Lasersabers ? I think is the question, if a spinning rotor has more energy than another at the same speed it would make sense that it would require more energy to get it up to speed and keep it there, keep it spinning. MileHigh and Tinsel Koala supplied all info needed to get the MoI of your rotor.

These pages are a great help if you want to find it..

Oh I meant to say that an Earth battery would run LaserSabers motor for free a few times over I think.

I have two dissimilar stakes driven in the ground about 0.5 meter and 2 meters apart one is copper tube the other is a galvanized steel picket. They would last for years, and is scrap metal.
I get at times up to 900 mV with some short circuit current which I don't have equipment to measure properly and don't remember the measurement I got last time but I could try to check, I'll need to find a better meter, I might use the uA meter I have set up as a field strength indicator, I'll just need to disassemble it, i'll try with a multimeter first if I can find a suitable one.

Conrad:

But I rather try to achieve OU with µA instaed of with 1000 A. At least one can fool oneself and others more easily with µA.

The purpose of the scientific method -- based on experiments with thorough measurements -- is IMO precisely to avoid "fooling oneself". 

And a self-runner, for example, keeping a cap charged while driving a load (however small) is a clear indication of tapping previously-untapped energy.

(I prefer not to use the term "overunity" "OU" as this conjures up notions of violating laws of physics; when it is more likely getting energy from a real but previously untapped source of energy.)

Thanks for your research efforts and experiments -- and thanks to Lasersaber for another interesting project.

PS -- recent motor by Lidmotor uses the DadHav 2-transistor circuit.

Also, on my electronics bench:  http://www.youtube.com/watch?v=oeACDx6Ne1w&feature=youtu.be

This little "Slider motor" will run just fine at 0.65V @ 38uA, so about 25uW.

JouleSeeker: My remark "fooling oneself or others" was an attempt at sarcasm, because since ten years I only see OU contraptions which are a delusion or a deception. I try to not fool myself and others, but one never knows what the future brings (again sarcasm).

Do you know how the "dancing-flower circuit" works? If there are four wires leading from the flat coil to the circuit, a trigger coil might be in use?

In the video only one coil drives the rotor, which is interesting. I am not convinced that more coils are necessarily better than fewer coils (with a higher DC resistance).

Once I have tried the coils from the relays which I have found ( http://www.conrad.at/ce/de/product/503614/Miniatur-Print-Relais-AZ943-15-A-Zettler-Electronics-AZ943-1CH-24DE-24-VDC-1-Wechsler-Max-15-A-Max-30-VDC300-VAC, 1600 Ohm DC resistance) I also want to try just two coils with 6400 Ohm DC resistance. One coil at 180° and the other at 360°, and may be 12 magnets on the rotor. Just one coil hurts my wish for symmetry (but I might be wrong).

I am also thinking about using bigger magnets (stronger magnets), because the weight of the rotor is not so important once it has started to turn. A heavier rotor might need a little push to overcome inertia and take longer to accelerate, but the needle bearing can carry a heavier load without developing much more friction.

I like the idea of a longer axle (as in the video) because the top magnet can hold it straight up easier (longer lever). Needles are easy to find and are very strong, but I have never seen very long sewing needles.

I also looked for sapphire vee bearings and it seems the only easy way to get them is from Amazon in the US (as Lasersaber indicates in his forum)? They come from China or India, but I could not find a source in Europe. I was thinking about destroying one of my older mechanical watches or better alarm clocks to salvage the jewel bearings, but this are "hole bearings" not the vee type.

Greetings, Conrad

P.S.: I found very long sewing needles
