How to create pulsed DC?

[z.monkey]

Howdy Y'all,

Pese, yeah I did have to flip those caps over.  They got hot and I blew up one.  Let the magic smoke out...

Fritz, there is nothing like an oscillating relay, buzzz....

jadaro2600, that is roughly 7 watts so at 17 V_DC That is around 400 mA.  You need mo power.  See if you can find a car audio booster.  Use a audio tone generator, feed it to the audio booster, then run the output into your rectifier circuit.  If not that then you can always build a protoboard circuit to run the electrolyzer.

A really simple way i would of thought, for testing purposes only, a small electric motor on its on power with a controller so you can adjust the speed at which it rotated... then just a disk for connections. you can adjust the speed the amount of connections the size and or length of the connections ect ect... simple efftective... CHEAP you can adjust everything.

i beleive we can do it using relay set as a vibrator mode.

I understand that real a PWM's effectiveness arises out of the
sharpness of the rise and fall. I suspect that, on an oscilloscope,
the relay method will give a "Mars bar" like shape, rather than
properly vertical rise and falls.

IMHO Creating pulsed DC is only the first step.  There are brute force electrolysis guys out there who use PWMs to control heat, but I think we should be interested in attaining and sustaining resonant pulse frequency.

A Meisner (or Armstrong) setup uses a pickup coil to switch a transistor.  Theoretically this is an automatically self tuning resonant pulse frequency generator.

Since it seems like a lot of experts have posted on this thread, I'll pose the question -- can anyone figure out a way to incorporate the Meisner circuit into their DC pulsers?
