Thanks for the info Romero.
Do you have any recommendations for a dc/dc converter?

Just powering one coil with hall circuit, @820 rpm, getting 22v in a 10000 if cap. Running off a 11.2v Lipo needing a charge. No bemf collection yet or coil shorting. Gonna build the self triggered circuit today if I can dig up all the parts.

Thanks!
Now I am using this one http://www.ebay.co.uk/itm/10A-DC-DC-600W-10-60V-to-12-80V-Boost-Converter-Step-up-Module-Power-Supply-UK-/350975904870?pt=UK_BOI_Electrical_Test_Measurement_Equipment_ET&hash=item51b7cb4c66
I have also used this one for low power experiments http://www.ebay.co.uk/itm/New-10Pcs-DC-DC-LM2596-Converter-Buck-Adjustable-Step-Down-Power-Module-1-5-35V-/370844697207?pt=UK_BOI_Electrical_Test_Measurement_Equipment_ET&hash=item5658110277


Thanks for the links!

Nice build there free_nrg, does your coil speed up under load while charging your lipo batt?
What gauge is the wire you used? Any videos? Thanks!

Regards

No speed under load yet. Coil is 20 awg. @442 turns 2.4 ohms. No videos yet. I need to build a better drive circuit. And bemf recovery. Just got it running last night.
For 2.4 ohm coil you will need very high RPM but you can use 2 coils in series to get speed up effect.
Another simple and cheap dc to dc convertor is any laptop charger or power supply for a desktop computer.
Most of them can work fine with input from 90 volts to 240 volts while maintaining the output voltage. Most of them are 18-19 volts  output but you can modify the output power or use it as is. You can apply ac or dc but if used to utilise BEMF from the driver coil then must change the input bridge diodes with fast ones.

Success,
Romero

Thanks, pls. Feel free to share your progress, my setup is slowing down with 12v 10w bulb load, but if i short it out, rpm almost doesn't drop, my coils are thick gauge wires, i get 9v with lots of amps, need to wind a smaller gauge to get sul...more to do.....keep it up....

Some of the parts for my new motor/generator arrived today. One coil ready, lots to go...
I am calling this one SRG4.

The new generator partially assembled, ready for a quick test.

Today I received another grid tie inverter. The previous one (Powerjack 1200) died after about one year of use.
Now I got a serious one EverSolar TL3200. Installed and tested just before being too dark outside and still got some power.

I have just received few flexible solar panels. Each one is putting out 92Watts/ 319volts. This is ideal for all professional grid tie inverters working with input voltages from 125-500volts.

Foarte interesante noutatile de la ROMERO !
Va rog ,daca puteti , precizati numarul de miezuri toroidale din schema cu oscilatorul cu BD139 si BD140 , alimentat de la 1.5 V...
Merci in avans.

chiar ma zapacesti... nu am idee la care schema te referi, am testat o multime. Mergi la pagina la care te referi dai Copy la link apoi dai Paste aici. ? Te referi la miezuri toroidale... la mai multe? sau nu mai inteleg eu bine de atata stat prin strainatati :)

Ref. la miezuri toroidale din schema oscilatorului cu BD139 si BD140 data de dvs.
nu reusesc sa fac copy link samd[probabil nu-i dotat softul meu , ca sa nu zic altceva..]
INTREBARE : 1) pot face un mic clip video pe youtu..  si sa va trimit linkul
                     2)pot trimite un email pe adresa dvs. , daca aveti una
Tank , in avans !
