Begginer advice needed

Thank you Tinselkoala. That's very informative. So, I could do with catching that extra energy and feed it back?

You're welcome, and thank you!

To capture or "siphon off" the inductive collapse spike you can connect a fast diode, like UF4007 or BYV26E or similar, with its anode at the Collector of the transistor (junction of coil, transistor and neon) and its cathode to the Positive terminal of an electrolytic capacitor of, say, 22 uF 400V. The negative terminal of the capacitor connects back to the battery negative.  The capacitor will then charge up to the peak voltage value of the inductive collapse spike. You can monitor this voltage with a DMM set to the right voltage range, across the terminals of the capacitor.  Be careful doing this, don't exceed the voltage rating of the capacitor, and also beware because the capacitor can store a lot of energy and release it all at once if you let it. The more capacitance, the slower it will charge but the more energy it will build up. The neon probably won't flash until the voltage on the capacitor starts exceeding the threshold value of the neon.

You could also put another battery in place of the capacitor, and "spike charge" this second battery directly this way.

The only problem with this whole scheme is that all the energy comes from the main "run" battery in the first place. It's not really "extra" energy at all. But normally it is just wasted in heating components or flashing neons, and it may be put to better uses than that by using some kind of "siphon" circuit like I've described above.

You may find this short video of interest. It's part of a longer series of videos developing, testing and describing the "MHOP" better-than-Bedini pulse motor.

oh wow, i didn't know people still play with Bedini gadgets.....

I like your neon circuit pulse idea. Bedini's older motor that had a secondary wheel that would fire a mechanical switch after a
capacitor had taken several hits from "bmef". This is because the back emf pulse may not be what voltage the battery is looking
for in terms of recharge.

Well, when there's no football on the telly, what else is there to do?
