23,000uF caps
« on: July 09, 2014, 07:24:32 pm »
Stopped at my local scrap yard today and they had a bunch of 23,000uF 75VDC caps, I think made by UCC. All sitting on top of a skid, looked new. Probably 50 to 100 of them. What would they be useful for?
I didn't inquire about them but they may be available for cheap. Give me a reason to pick a few up if I can. LOL

Audio people like them for smoothing out linear supplies and as tank caps so that when the amp "hits" it has a resevoir to draw power from.

Well, you could put them all in parallel and vaporize random bits of metal  >:D

you can make a circuit with boost converter(over 50v under 60v) and make your high power discharge system.Then you can explode whatever you want.

See if you can bum them for $1/lb or less (it's not like they have much if any scrap value -- they are literally 50% oxidized aluminum!).  Keep a few and eBay the rest in small lots.

You could build a nice battery tab spot welder...

Please tell me they're in Arizona!

Sorry, but there in NJ. If I get a chance, I'll stop by and see what kind of deal I can manage. Can't they be used to make a small rail gun? Be something neat to try.

Build some big flash guns and sell them to photographers. Many laser systems use large capacitor banks as well, went to a hospital once and there was this heavy thumping going on upstairs making the whole floor and ceiling jump, I inquired as to what was going on and was told it was the laser in the operating theater.

I could use a few if shipping was good, as general buffer caps on batteries.
