More Capacitive Discharge cutting of household objects

Watch in HD! New controller board, LCD, torroidal transformer, high power bridge/regulating circuitry and Zirconated Tungsten electrodes (since they're pretty consumable in this application, Thoriated Tungsten is a VERY bad idea!)

Cutting through copper foil, the same stuff that used to be used in Tile Flashing as well as artwork/etching, as well as a Tin can that used to contain chickpeas. Note the LCD changes as soon as discharge starts/ends!

did you have plans for building this? or find it somewhere? if so where? this is a great looking build. would like to build one my self, any help on where to find plans would be great. thanks

@1crazyfocker

Hello, thanks for your feedback. The plans (schematics, description, photos and PCB Artwork) are on our website, see the video description for the direct link. I'm afraid we can't provide further support or firmware for this build though, so you'll need PIC/dsPIC programming knowledge to get it going

If you upped the capacitors a bit, could you cut something a bit thicker? Like maybe the door to a bank vault? Or even some plate steel?

[PodeCoet]

Hello,

Haha interesting question, I'd go with "maybe" for slightly thicker plate steel, but no way to bank vault thicknesses. If you doubled the capacitance (ie: placed them in parallel), you'd have to double the current rating on your bridge as well as the power supply. In theory you'd get thicker cuts, but your tungsten electrode would get consumed without an inert shielding gas

A plasma cutter is better suited to that kind of application, as the plasma does the cutting and not the electrode

Very nice machine. But sharing it, your work will

be more recognized. Thanks. Very inspirational video

[PodeCoet]

Thanks for the feedback! I'm working on a pulse-arc version, similar circuit, but different welding style and using argon to displace the oxygen. Hopefully it pans out

@PodeCoet thanks, dont know how i missed that

DUUUDE GLOVES!

BTW AWESOME LOL

Great Job !

Outstanding stuff. It really is. Well done.
