I've been using computer power supplies for my chlorate cell, and it works just fine.But i'm going to make a bigger cell with a rewound micowave
transformer, rectifier bridges, and some capacitors.The voltage is 5.5, but since it has no regulation there is a small ripple.Is this ripple too
prejudicial in a chlorate cell? Will it reduce efficiency?Do i really need a regulator circuit ?

I never had any problems. I tried with and without caps and a filter choke, don't recall it made much difference.

I never used smoothing caps either and they apparently weren't needed.

I'm doing the same thing except I'm using a cheap welder (exactly like Len did in 'Illustrative guide to sodium')
I have a couple of questions. First apparently my pulsed DC isn't regulated enough for a volt meter to show it. It shows fine with a DMM, but it won't
show at all with a voltage LED. It bought a battery cap for a 9v battery and it shows voltage from than OK, but not from my meter. I have the same
problem with my amp meter.
I'm also interested in getting a 'low pass filter' 10 hz. so that I can see my amperage at the RMS, not the 'useless peak' as Len mentions. I've
looked for a filter on ebay and can't seem to find anything. Since it's only measuring amps across a shunt, I wouldn't think it had to be built with
much copper at all.
Does anybody know of a cheap way I can measure voltage and amps using my existing voltage and amp gauge, some way to smooth or regulate good enough
the current so it shows?
And I'm just as confused with the low pass filter, I know what it does, but not where to get one or the specs really either.
Thanks in advance.
