i have taken a dead psu apart and found these are any of them any god to use in a pulse motor 2sc2625 or this one 2SC5353

i've used the 2sc2625 in a bedini SG circuit before.

thats god news then i have managed to salvage 2 of them.
is a 250 volt neon ok or dose it have to be a 110 volt neon?.
i have built a pulse motor with a reed switch worked very well on a hdd drive motor and disk 16 6x6mm neo mags but burnt out the reed switch.
so i made my own more heavy duty one but there was to much rf interference been created so hopeing the bedini style will work better.

Hi Dasimpson to eliminate spark in reed put it between BR on AC side with low voltage diodes. Pulse motor have more torque.

what do you mean br ac side they is no ac side the power is from a battery

the set up went + of battery to read switch then to coil from coil to battery -

Hi Dasimpson yes it's from the battery but when the coil is pulsed it have BEMF as AC so put four diodes 1n4001 facing one direction (Bridge Rectifier)
then between them one put the reed switch. One side coming from battery and the other from coil. You can fill a capacitor on the DC side.

so what you mean is wire as nomal but take a connections of ethier side of the reed switch run thru a bridge rectifre to a cap.
lol allready ahead of you there did clench some of the spark but the rf interference was to much.
i was going to say the bemf is pulsed dc but then i relised that the pulse going to the coil would be going the opersit direction so efectivly makeing this ac.
i was also hopeing to run some leds of the cap but when i tried it the motor boged down.
my idea this time is using bedini style circuit an using the hdd motor as the rotor.
i am going to take the old connections run as 3 phase star configuration and see what power i get from that

Found this tread really helpful, thanks too u all!
Ive not got much helpful info too post just a couple of questions if someone
Will help me out?
1. If I was to use a latched hall switch (pulses on both poles) then would
I need to have a transistor for each hall output?
Im a noob so trying too fully understand before I frazzel parts.
Been reading that site totally amped someone posted link back somewhere near page eight, I think?
Brilliant for people like me.
I get whats going on with this dynamic system.
I know how to make a cicuit for a unipolar hall with three legs, ive only got four legged, thus my question would I needto eessentially double up the circuit?
Hope that makes sense...
2. Could I put a non polarized capacitor in place off say the bemf capturing off of emitter and v++?? Just wondering if that would act as a sort of pump timed by when its full and shorts? Giving the rotor like a current boost??
Cheers
