No place suitable to store them.
Problem came when CNRC came to visit.
All of us got told about the dangers of storing so many
Sources in a small confined space.

TJ, how long have you had the pulse cap - it'll probably need reforming.

To do this start with say 250V and work your way up. You dont need amps of current to charge a cap of 4uf, so for example, you could (in theory)start with a flash gun circuit. Put a voltmeter across, and let it get to 250V. Then let it sit charged for 15 minutes. Then put a big resistor across it (30+Kohms) and let it bleed down to zero.

Then charge it to 500 V and so on. Once your flash charger blows up (Coz it cant go hight enough, find an alternative method to charge it.

reforming a big cap like that ensures it doesnt do stupid things like blow up when you try to charge it from a MOT with a diode.

Once you get to 1000 volts, try discharging it into a target, something attached to a plastic pole or pvc pipe. make it long - pulse power can send bits of hot metal flying.

I really just want to throw it in the trash. But its full of PCBs so I cant. It was an impulse buy. If I wasnt such a moron with electronics I wouldnt have bought it. I've been trying to give it away to someone who could use for a few years now.

Large priority flat rate box is just over $15.

I'm not sure if parcel post would be cheaper. Its heavy.

Mm.

Damn myself for spending my money so quickly... I've got $3 in my paypal account. Woo. :p

I'd get it if I had more money for shipping. It might be a while though.
