That does suck!. Can I recommend that when you get your new transistors get a pcb style board with the holes all punched in it. mount your transistors on it and clean up your circuit as much as possible, keeping connections as far away from each other as possible. Perhaps there is a short somewhere and this makes things easier to track down. Nice setup otherwise, bet that rotor gets up to speed!

Hang in there, I know how you feel, I have a pile of toasted components here too Consider moving up to the mjl21194 transistors as well, or though you'll be crying harder if you fry them at 5-10 bucks a pop. If your local store doesnt have any more 2n3055s there are other similar subistutes.

*Warning! Frustration being vented!*

i am getting really p'd off now! I set up my dual coil motor about a week or two ago (3 transistor circuit) and have rebuilt it three time now because every time i turn it OFF all the transistors mysteriously (and subtly) fry! I don't get it. It runs great for hours with no heat in the circuit but then as soon as i swap the batteries for the first time (always disconnecting the primary battery first) it stops working! After investigation i find all three of the transistors are dead! The neons are hooked up and i have never had any problems like this before. It only began happening once I started using a higher guage wire to connect the batteries and balanced the circuit though i don't see why that would do cause it to fry from being turned off.

well, now there are no more 2n3055 transistors within 50 miles of here so have to buy them online. Hopefully theyll be here before the weekend!



sniff sniff... my poor baby...

Something you might find interesting, at least I did.
With your wheel shut down, hook up an "analog" ohm meter to the coil, power or trigger, check the ohms while the coil is "between" magnets.
Now spin the wheel by hand and watch the meter.

If you have a spare magnet, try passing the South pole over the coil.

cheers! that sounds like what it is doing!

though the motor can produce multiple pulses per magnet which doesn't really make sense so I thought there must be something turning the transistor off to produce pulses instead of one large pulse.

then i thought about a transformer... when a magnetic field is formed in one coil a current is created in the other coil in the opposite diretion (assumung they are both wrapped clockwise or anticlockwise... lens law or something, lol ) so i wonder if this is this is what rapidly turns off the transistor and causing the current to pulse rapidly instead of gently like a sine wave and allowing multiple pulses per magnet.

I just noticed that you don't have the D1 diode marked in the schematic??? I was just wondering cos I have got my dual coil working fine now but have included a 1N4001 per transistor...

I can't find any where that says what this diode is for but am i right in guessing that when the power coil fires, its magnetic field induces a current in the trigger coil in the opposite direction to the current induced by the magnets and thus quickly turns off the transistor as soon as it opens which creates the sharp pulsing? So this diode allows the "backwards current" to flow freely while forcing the induced current from the rotor into the transistor.

im not positive about the full function of that diode but i did see a schematic with it being called a flyback diode to stop current from damaging the transistor

heres wiki Flyback diode - Wikipedia, the free encyclopedia

voodoo, I too am searching for ricks schematic to apply to a fan I have already modified. I need to grasp the basics of the scr and how it wires up correctly. I emailed him and despite being very busy he answered promptly. He said that the schematic would come with all the kits he sold, and that it was just another way to wire it up. He told me to go ahead and just do the 555 timer as it is just as if not more efficient.

So if anyone has a better understanding of the scr and its function I would be greatful, otherwise I will probably just move on and figure out a mechanical switching like Aarons with the copper tabs or step up and try and replicate the 555 timer.

Ren,
all my transistor bases have their own 100 Ohm 2w resistor and are connected to the 1k pot. The resistors are on the other side of the plate. All the emitters are connected together and to the "-" terminal of the primary battery. I attached a circuit diagram:

So this diode allows the "backwards current" to flow freely while forcing the induced current from the rotor into the transistor.

If that is the case then only one of these diodes should be needed even if you are using multiple trasistors. Is there and advantage or disadvantage of having more than one diode?

and while on the subject of diodes... the 1N4007. I noticed in one of bedini's diagrams that he had a "diode cluster" (about 3 i think) going to the positive of the charging batteries from each transistor. Is this to reduce the impedance of the radient? Has anyone else used more than 1 diode coming from the collector?

and somebody mentioned in another thread about using a ground wire connected through a diode to the positive of the main battery. Cant remember which thread it was. I don't have the luxury of a garden (living in the penthouse! lol) so I have connected an 18" radio antenna to the postive in the same fashion and it pulls .024V from the air into the battery... Tried a 4 foot antenna as well but the voltage was the same so just using the smaller one. Do you know how many volts were coming from your ground wire?

A ground wire seems to make sense since , as bedini found out through his pendulum, radient energy alone can't keep batteries charged so a ground wire could possibly feed the batteries the extra electrons. Again this is all guess work!!! Anybody have some insight on this?

well i made a new coil waiting on my transistors to see what this puppy can do
its 3"long the core diameter is 3/4" and its windings are 1 5/8" thick, its around 450 windings 4-24 awg power and 1-26 awg trigger

after i made it i thought it seemed too long now im wondering how the shape effects the system so my next coil is gonna be a bit shorter and fatter i got the same amount of wire left that i used in this one so why not the ****ty part is it took me like the hole day to make :O my neck is soar from looking down for so long

cap discharger

Hi,

Not sure about Rick's schematic.

Maybe this will help...this is what I did with an oscillator:

You can check out my youtube vid on basically the same circuit with an SSG:
YouTube - Bedini Negative Energy SG capacitor discharge

and more details on this SSG:
YouTube - Bedini Tape Motor SG -

If you do find Rick's schematic on this, it would be great if you can post details in the cap discharger thread:

Hi Aaron,

Thanks for your patience. I found the thumbnail but i already have this. I was looking for the capacitor discharge setup that uses an SCR/NEON or SCR/555.

Hi, this is the direct link I provided that goes to the post with 1 thumbnail:

[voodoo_chicken]

Hi Aaron,

there are 4 different thumbnail in your post, not sure what i should be clicking on .. i clicked on all of them but could not find what i was looking for. Any chance of a direct link?

Thanks

brushless fan sg diagram

Thanks!

You can click on the thumbnail pic in this post in this same thread:

I believe that is the fan diagram.

Brushless Fan Schematic

Hi all,

I have just joined and was wondering if anyone has Rick's schematic for the brushless fan setup with capacitive discharge on the negative side? Aaron, interesting youtube video

Thanks.
