Bedini SG

transistor may be damaged?

[Jetijs]

The buzzing sound is normal, that is because at higher base resistance the coil and the transistor starts to self oscilate. I can do this with my SSG if I increase the base resistance to about 900 Ohms, then there is that high pitch sound, the wheel is not turning but the charging battery still charges up while the primary battery discharges. You can run your setup also this way, but that is not as efficient as when the wheel is turning

ah ok thanks, good to know.

as i was playing with my sg i accidently kicked my output wire off, resulting in a fried transistor so put a new one in with a neon bulb this time, Then what, a short in my coil. Trigger and power wire touching eachother
well fine fixed that. Connected everything up, started it woohoo! went into self resonance with the bulb lighting up, accidently touched the wrong wire. DAMN! that hurts ive had some nasty shocks before, but nothing like this one! my chest still hurts.

so not having my day today.
now its running again, trying to revive a 50amphr car battery.

i also have the buzzing sound when my sg is not spinning if i disconnect the charge battery it gets louder !? is it really normal?

oscillating sg

When disconnecting the charge battery on the output, it is like having a larger diameter exhaust allowing the motor to turn over faster and with more ease. There is less back pressure in the circuit.

Reduce the resistance at the base to get rid of the oscillation. You don't want this effect if you're using a rotor. Otherwise, you can tune the oscillator if you want it to oscillate and don't want to use the rotor.

well i tried reducing it and even tried it with no resistor could the buzzing be due to a short in the coil?

[gabriolaman]

i have found with a single strand tightly wound slave coil i get higher voltage collapsing spikes would this be a desired effect meaning a better voltage potential to a quire my radiant energy??

Bedini Battery ?

Hello to the group,

My name is Mike, I started researching these materials very recently, glued to the computer, reading and watching experiments from so many of you for the better part of the last two months. I feel like I just woke up.

Am I understanding these behavioral concepts right ?

The collapse of the pulse triggers a higher voltage potential in the exciter coil. This potential is then opened against a dense receiver of charges (the battery).

The charges rush into this potential from everywhere it can, from the wires, from the battery, from the air, from the ground.

The polarization of the battery's relatively large reaction cross section draws much of the charges into this space. The effect can also be seen outside of the battery as well, acting like a gas, drawing charges into it.


If this is correct, what sort of battery would be the most efficient at receiving negative energy, of being a conduit for these charges?


This question may be off-topic but is anyone working in this area or interested in it?

[gabriolaman]

well i really wanted to get my second coil hooked back up so took apart an old power supplies i had and found two npn transistors that seemed to be compatible wired them up in my energizer and im getting double the charge i was before and only using 90 ma i can not understand but im using 2 thirds the power i was when i had 1 coil hooked up now i got 2 hooked up
the transistors im using are here 2SC2625-T3P-T pdf, 2SC2625-T3P-T description, 2SC2625-T3P-T datasheets, 2SC2625-T3P-T view ::: ALLDATASHEET :::

Temp OU?

Hey All!
I'm Rod from Ohio. (Please don't hold that against me!)
So far I've built 2 working SGs, one mini and one full sized. The full sized is currently being upgraded with a new rotor & more magnets.

Anyway...
If you all don't mind, I'd like to ask a question. Might be a dumb one, but I just can't seem to figure it out.

First the setup..
Capspan rotor with 8 double stacked neos, 150 ft. of 22 & 26 wire with r60 welding rod core. A 1K ohm (986 actual) resistor on the trigger. The 1 ohm test passed with .16 volts and no NE light up.
Primary bat is a converted 200 watt PSU putting out 12.46 volts.
Charging battery is a worn out 12 volt cordless drill pack showing 3.688 volts.

K...now the good stuff!
Input from PSU....75ma
Output to battery....105ma!
(I've charged up at least a dozen batteries and have never had these numbers)
About an hour or so later....
Charging battery 5.91 volts
Input 87 ma
Output 87 ma?

I load the battery down to 3.60 volts (after an hour of resting) and start charging it again. This time using a 630 CCA 12 volt starting battery on the back end.
Input 80 ma
Output 110 ma.

So the questions is...
What is it about this old drill battery that causes the SG to be in over unity at low voltage?

Thanks in advance!
The cornfused noob!

Hi guys,

Posted a couple of vids on youtube about the bedini motor for beginners.

YouTube - How to Build a Bedini Motor ... Part 1

YouTube - How to Build a Bedini Motor ... Part 2

If you notice any absolutly horrible errors could you let me know and I'll edit the vids before too many people see them!

Cheers!

edit: oh yeah, and some of the images can be found here:

Thanks, thanks, thanks!!!

Since I've been struggling with the Bedini SG for a while and just gathering the required components it was will real pleasure that I viewed your videos to at last learn about how it all goes together!

I guess I'm just too dumb to figure out how it is done from all the other recipes.

Glad you liked it

for my first circuit i built it exactly like the schematic so there were wires everywhere but little by little eliminated them all and ended up with that layout.

[wizzle]

Sephiroth, that was a top notch "how to" vids!
The numbered wiring was a VERY nice touch. Keep em coming!

i came across this neat bedini energizer YouTube - Micro_SG - fastest, lowest power SG on the planet!
