Hi guys in this forum gadetmall posted this schematic. Can anyone explain me these components please especiallly where there is FSMR parts cause I need to build a battery swapper?
Thanks

That circuit has not been explained by the author, I asked him but got no answer.
If you like to try asking him on his topic go here and post your question:

Thanks NievesSoliveras
Did you ever build a battery swapper for bedini or other chargers?
Thanks again

I built a battery swapper with a DPDT switch But it did not do the job. I mean it did not charge properly the batteries. Or my batteries were damaged already.
I moved to try an automatic one, because that one was manually switched.

Regarding @gadgetmall's circuit, I was looking at it yesterday and that fsmr seems to be a single post double throu relay.

I think that to swap properly the two batteries the relay must be DPDT.

I think that it works by using the negative output of the 555 timer. I dont see it using the positive output.

@all

I made this composition from a circuit posted by @mk1 from the youtube video he posted here:

I do not have the triac 600v 40a needed
The capacitor betwen the transistor and scr can be a flash capacitor from a camera circuit.

If any one wants to try it and report, it would be well appreciated. I am short on funds to experiment.

I posted the circuit on the joule thief thread first because it is a joule thief and @mk1 posted his circuit version there. I made this one from his.

There is a forum member that has had success with the self charger circuit. He is known as @resonanceman.

My circuit has been failing me, but it seems that it is working for him.
Look what he did:
