The Alternator was a good choice because every thing is all ready made for you.
I am going to insert magnets into the rotor
and remove the second battery.
the back EMF from the coil when the transistor shuts down can give you a real good shock.

Thanks toranarod …
Thanks toranarod putting up the schematic would be great if you can .

Hi , looks great ? …
Hi , looks great ?
So you not using a bedini circuit , your using a reed / transistor pulse motor setup .
reed triggers the transistor which fires the stator coil which in turn spins the rotor ? is that right ?
Id like to replicate , if you could provide some details on circuit , also have you done any modifications to the alternator besides putting magnets on the front ?
because seems to spin pretty easily .Well done you may be onto something.

The Alternator was a good choice because every thing is all ready made for you
just remove the Diode packs and drive 12 volts
straight in to the brushes.
and connect a transistor switched by a reed switch. The only thing is the coil resistance is very low so you need Darlington pair transistors to get the gain up if people want I will put a schematic up .

Looks like fun, …
Looks like fun,surely the alternator is 3 phase,dont you have to alternatly switch the three pahses on/off and provide power to the armature to make it a magnet for the the feild windings to repel and turn the shaft?Bear in mind I know nothing of pulse motors,well not much.

ok i fread about a way to surpress emf to stop short but i forgot were so stop the emf and you will be more safe

Interessante démarche, vaut la peine d’être d’experimentée.
