@All,

some udpates: my board is still not functioning (the one Groundloop sent me) but I am working on a new version with more switches (about 14 I think) so that I can do more experiments. It will also use PIC16F690 because I can real-time debug it using PicKit2 Express Debugger straight from the MPLAB IDE.

Groundloop is sending me his latest designed board with relays (wonderful).

And to complete the learning process, I am also en devouring myself into making a pc cooper board using my own design by myself at home (oh boy, I love the chemicals smells).

Fausto.

Wow Fausto; that takes a lot of effort. Give up soon if you run into
problems. That used acid with disolved copper is a toxic material. Also,
plated through holes are done with a carbon powder, not something
easily accomplished at home.

I know, but how much fun it is??? It is lots of fun I tell you. Today I got my board inked but I made a mistake of having it inverted (oh boy). NO problem, tomorrow I will redo the PCB again and finally etch it.

I already purchased a drill press from jameco (only $30 bucks) to make the drill holes. My design (actually it is really Groundloop's design I only changed the PIC and added a few more ports) is going well.

So much to learn and so much fun. I only remember having such a fun when I was a kid!

Fausto.

Today I got my new board from Groundloop. THANK YOU my friend.

Beautiful board. Now I have so much to play and learn all over again.

I also found today this interesting old post http://www.overunity.com/index.php?topic=2118.msg28507#msg28507.

Today I finally finished my new 14 switches board. Tested and read to go.

Fausto.

ps: almost ready. Still missing 2 connectors.

Fausto,

Well done! :-)

That is a good looking board. I am impressed with your handywork.
Let us know what experiments are getting done with it.
Once you find some overunity energy - I'm very sure more will follow.

Hi all
I did a lil experiment this morning that may be of interest.
I have a simple pulse motor setup using 2 AA nimh, a coil, and a reed.
I used a diode and a wire off each side of the drive coil to charge a separate cap, which charged to 25v. Then I used another coil, not near the rotor, a reed, diode and another cap, and the reed is pulsed from the rotor, taking from the first cap, 25v, as a source, and the second cap is at 222v. I havnt tried a 3rd stage yet, but is it possible to keep adding stages?  has anyone tried this?
I tried a 3rd AA added to the other 2 and it went above 300v, my caps are 275v, so I just did it briefly.

@Magluvin

thanks for sharing your experiment. It is indeed interesting. Could you provide a schematic and a picture of your setup, please?

Fausto.

Thanks. Yes I will. Im running up to my shop to get some other caps to try and I will do a YT vid. The 2nd stage seems to have higher current also compared to just a first stage bemf, maybe its just a bigger blast. Also I would think that the first stage bemf would have been higher than 25v but so beit. The rotor makes a great timing/switching for the application.
Be back in a lil bit

Ok Im back with the gidgits. Im just going to clean up the setup so it is easy to understand what is what for the vid and my cam bat is on charge.
Will let you know in a few when im uploading.

@mscoffman

I am impressed with myself too, really! I never done this kind of work before BUT hey I did a huge mistake that I found out today, I used the wrong paste for the soldering and it is very conductive which made ALL my transistor to be on the ON state all the time. I just found out while testing the remaining parts of the board trying to use the batteries again.

Oh boy what a mistake. Now I have to remove the chips and wash the whole thing with soap until all the paste is gone and hopefully make this work correctly. Lesson learned, plan, plan, plan and than plan some more. Make sure to get the ABSOLUTE correct tools for the job, no cutting corners.

And if I ever find overunity, no problem I will share right here with all!

Fausto.

Ok, I uploaded a vid on the 2 stage setup. I had a bit of reed problems and when the rotor is running it covers my voice a bit, but I think it shows what is going on. Ill do a cleaner vid tomorrow if necessary.

@magluvin

I am impressed with your method. But a word to the wise. You cannot run your
capacitors at any voltage above their working voltage even briefly, without potentially
damaging and punching through the dielectric insulation. There need be no margin
above the official WVDC working voltage direct current and so the margin has to
be below the WVDC number.

@plengo

My experience in the PC board stuffing industry in silicon valley...100% removal of
soldering flux was an absolute requirement because as it ages it can cause corrosion.

Fortunately almost all componets on the board are sealed against water.
So guess what?...on the production line they wash and dried the production
boards in a standard dishwashing machine. The high temp water removes it
completely. Certain components are obviously not rated for water immersion,
dip switches, variable resistors, plastic encased relays, transformers etc,
so they leave those componets off the board and carefully solder them
in later. If you let the machine run through a cycle to clean itself first
you can do this too, using standard dishwasher crystal cleaner.

Thanks Mscoffman
One key ingredient is the diode on the drive circuit. I could reverse it and get 240v and store that in a cap, but it will be nill for any current capability. Lets say I put a 10k resistor across the cap, that 240v will end up about .5v, maybe. But having the diode in the direction I have it, Im still turning 2.5v into 25v in the cap, but the current handling is much greater. I can dump the 25v into a very low ohm coil with the second reed and get 270v, put a 10k resistor across it and get 25v and a 1k resistor and still have 5v across it. So it increases the current handling on the second stage very well and no load on the rotor drive.
I have since eliminated the bridge to a single diode like the drive circuit.
I need to get some higher current reeds and some high voltage diodes and caps to try a 3rd stage. It just may go a good bit over 1kv and maybe with some current handling.

Some may see the vid and say, why am I only getting 25v of bemf off of the drive coil when I could get 250v without the 2nd stage, but there is no current capability that way. Try it, it works. =]

Honestly I cant say no additional load on the rotor drive and bat. , there is a bit, But the 2nd stage coil Im running now is .9 ohm, a big audio filter coil. Im getting 270v on the secondary output. If I used it as a drive coil, my battery would be cooking.
Ill do a vid later with the big coil.
