here is my finished buck converter design.
seems to work very well.
electrolite was used
i will test it further
consumes 18 amps @ 12 volts constant
very little heat in the circuit and no cooling fan is needed
does make a little noise.
points do wear out over time, but can be easily changed.
points can be replaced with dual mosfets, but heating will acure with the need for a fan
@H2Truckers
its the same as i posted here.
youtube email me your other email. i will send a clear schematic and help.
its easy to build. i made it that way..... and give it freely....so everyone could join in.

@irondmax Ok yes I would like a diagram on how you do it cus I have ben using a ATX power on the 5.5v at 15 amps .
I have a no curent los dry cell that I have ben working on.

@poprock4me irfp260 46 A .
should be good.
irf640 is 18 amps.
you should figure your length of wire. important not to splice it.use pie R squared x 100 turns. then add a little. 2 coils also.
less amps carried means you can use smaller wire if you like. but mine seems to work well, good idea to do that way.2 colars wire for 2 coils , solid wire not , NOT,stranded.and rubber insulated. we call it romex. for the house.

@H2Truckers i found a supplier that has most sizes availible any length. 304 or 316 stainless. stainless is mostly nickel.
i will check though.
still not decided on my gap.
i used the relays because no fan needed to cool them. and if they go bad. easy to replace. plus i think points give a much sharper power spike.
also relays will work for pos and neg. and if i want say 200 amps....i just add more relays. still no fan needed.
if you need clearer circuit diagram let me know

@irondmax i am not familiar about the irf chip , is this a mosfet ? how about
irfp260 mosfet . . later i will buy haft kilo of copper wire gauge #12 , then follow your
instructons , the only i need ampheres i think to increase maybe until 10 amps or 15 amps , because my battery is only 5 amps for my scooter . is it possible for 3 volts we can raised the current more than 10 amps . i post last nigth im using 5 amps battery then direct connect to pwm to cell , i start to 5 amps ,

@irondmax Pipes are good, Have you looked in to nickel pipes I have seen them at home-depo for about $35.00. HHOPOWER made some goog steps with it (nickel) and I think that with your buck converter it will work very well.
I am going to buy the parts to build a buck converter like yours I think you did a good job on it thou I will use dual mosfets.

@H2Truckers
pipes all the way.
i have another test to run to see what spacing i want on my pipes, these you see are 1/8 spaceing........toooooo far.
i want to end up with 20 or 24 inches long. 9 sets.
meyers said the pipes are better because heat is controlled by the shape at the end of the pipe. also the wire connection should be at the bottem. this aids in the voltage burst out the top.
also i have a theory about something meyers did not say,but i noticed in his video. noone else sees it

@poprock4me i will check rod diameter and number for you tomorrow.
you can try you pwm with the inductor.
i think its best to use the irf chip to drive 2 car relays. you can drive the pos and neg wires that way, or you can add more relays and inductors for more amps.
easy to go from 5 amps up to 200 amps.
if something melts it will be the relay.....cheap fix.
i have many more ideas for this circuit......many more

@irondmax Ok I will so if you can PM me for some help I will like it.

Are you going to us a wetcell or a drycell after you are dun with your testing?
