Salvaged power supply for a project box to build my prototype electronic pulse width modulator circuit.

  • I don't mean to nitpick but why did you mount the heatsink on the outside (which seems separate from the mosfet)?

  • @bitsurfer0101 Because it's mechanically desireable and still thermally bonded. This is accepted practice.

  • i just converted my bong into a bubbler

  • Better use for it anyway. Half a lifetime ago I discovered that being straight and thinking clearly is the best high of all. Just wish I had never started down that path in the first place.

  • iv watched two of your videos and learned more about these cells and how i will eventually design mine than i have from any other videos, you describe the components clearly and you dont have southern accent :P

    also you use sodium hydroxide for your electrolyte right, where can i find it?

  • I actually use Potassium Hydroxide now, KOH. Got mine from a friend. I have found it online via mail order though.

see all

  • by the way what is the resonant freakwhency of an 18 plate getup like yours and why cant i take underwater transducers and see if the electrolyte solution likes to disco as the dj beats and mixes in quad or stereo to get those electrons to excite and move faster and while the cell is emitting? what would happen?

  • am now in pursuit of grade 316l steel at .048 thickness at day 6 of cruising the info highway with the turn signal on wearing a hat in a convertible running on rainbows with the green meanie mib in pursuit of my meager assets

  • hey from sc...i consider you the charles fillmore of energy...lol...i gotta good idea...why all the fuss about current...just put 1,2 or three high amp diodes, cheap and dirty in series with the electrodes...that knocks the thermal runaway electron brats (cuts em right off at the knees) ...eh knee voltage.. at .6,1.2 or 1.8 from 13.8 would be 13.2,12.6. and 12 volts supply that backs the nast dreaded knee back in theory...but in practice may mess up efficiency?

  • I love your videos.

    Just a thought...

    Was just wondering when you give a bunch of initials, if you could write what they mean on in the about video. Just to make it easier to catch up. I get that this is Pulse Width Modulator (PWM), but in others you have the VSPB Cell etc, and you don't always mention it. I say this from looking at the about text to decide which to watch etc.
