TeslaCoilBuilder, That's a scary capacitor bank.

I didn't notice any discharge resistors in the setup.

yes, but the pic is not up to date, I have some discharge resistor on it now

I think those guys got their capacitors surplus, from some huge industrial inverter drive that was scrapped in Germany. I've seen photos of guys dismantling it with cordless drills and stuffing the back of an estate car full of capacitors, but I can't remember where I saw them.

The caps are from the German Railways.
Possible you have seen it on the CTC-Labs forum

Wow I have never see so many capacitors in my life, that is a truly amazing sight!
Were the capacitors heading for the bin? Did you get them for free? I'm curious now...

Hmm, well I haven't had much experience of buying MTB parts on Ebay, but it has been interesting.

Well, my brother is an MTB addict. If his wheels aren't bent yet, they will be by the end of the day. He's constantly trying to buy new parts, and very often, you'll find the seller bidding themselves under another name in order to crank up the cost they get for it.

I myself am not interested in mountain biking for any more than actually getting somewhere or casual riding - the act of hurling onesself off things doesn't appeal to me.

Here's a neat picture. I'm sure a lot of you know exactly how I did it, but it looks nice anyway.
There's no photoshopping, glue (or other adhesives), they're not soldered/welded together, nor are there unseen supports round the back.

I also had a very nice picture of a frozen spider's web somewhere, but I can't instantly find it. It was a touch out of focus, but that actually made it work well.

Bingo. There's a neodymium magnet out of a scrapped hard drive under the sheet of paper.
Most people don't realise that (modern) 1p coins are magnetic, which makes it an excellent photo for confusing people.

The magnet in question wasn't quite powerful enough to hold the top coin in place as well, so that one IS actually balanced on everything else.

I'm still trying to find the one of the spider web on this computer, but if that fails, I know where I have a copy of it.

"260 6000ÂµF 385V caps"

That is 115 KJ worth of energy storage!! You should build a PPDRSSTC(pulse powered DRSSTC) with those caps and generate a monster arc.

I'm guessing with that much energy that wouldn't classify as an arc anymore it would be more like a lightning bolt, haha.

High voltage rectifiers, 2X2A and CV1290. Glass components truly are beautiful. Producing x-rays should be no problem with these tubes.
