Hi all!

Do you like my new capacitors bank?

this beauty is able to store a maximum of 2800 joules and have a very low ESR, the following video shows the MAGNEFORMING of an old 5.25" HDD platter at about 2200 joules.

very nice! One thing i would suggest though, is make a scr triggering circuit because triggering it with a 9v battery alone may ruin it. Especially at those powers the battery doesn't supply inough pulsed current to trigger the gates properly. Trust me, i have lost several scr's that way.

My total collection of electrolytic caps to date. I'm thinking either big discharge bank for wire exploder, can crushing/magnaforming, or multistage coil gun. I picked up these big beefy lytics today, $12/piece, and they are the biggest caps I've seen yet. These sized caps are hard to come by especially up in Toronto.

Nice caps!

I just scored 12x BHC 4700uF 400VDC caps from England at only 25 euro, then another 25 euro in shipping to Denmark. So ended up costing me merely 6$ a piece, came in factory box with screwset and all :D

$#@^$ Why does *EVERYONE* have access to cheaper caps in their country >_<

Anyway, whee, more pics. SCR + a pair of salvaged heatsinks from some P2 processors, and my supposed layout for the cap bank....

YAY! I finally got my coat of arms from the Disneyland Armory.

Now I know some of you will say ... but Unicorns.. you should have gotten Lions.. Unicorns aren't very masculine. Well, you might think that, and that's fine, but Unicorns mean a very nasty fight to the death, they were regarded as the most ferocious creature on a coat of arms, and I think it's just perfect.
