Maxwell's (copper) hammer

[WizardG]

This a little toy I've been working on. Not laser related, more like industrial power electronics, but fun anyway. Maximum output is ~1kW. It runs off of an 18.5V LiPO pack and if you stick a 1/2" iron pipe in the coil it'll pull over 60 amps. Enjoy! (bonus points for identifying the background music) MVI 3598 - YouTube

Working good... Pink Floyd?

Half points for the band, now name the album:yh:

Is that like wirelessly shorting through the metal and causing it to heat? If that is way off forgive me. I am unsure what that was, just trying to make sense of it.

Its a form of induction heater looking at it , so High frequency AC in the work coil induces eddy currents in the piece in the coil causing it to heat up

What driver system is it ?

It's induction heating. There's a resonant current at 112 kHz in the coil of about 100 amps. The eddy currents set up in any conductive (metal) item placed inside the coil heat the object.

It's a royer topology. The finished unit will be a handheld pretty similar in size to a commercial product called the mini-ductor. But mine is cordless

Thought it was something like that : D , I'm guessing its the type with 2 inductors linking each side of the work coil to the DC supply ?

It's the cordless part I like

Right you are :beer:

It's alive! Not pretty I know but I can make the case a little smaller and I think a steampunk theme would work to dress it up

Induction heaters are awesome, but the best part about this is that you are using it to heat your titanium nail! :shhh:

Also your voice sounds like some sort of cold war video narrator haha
