    BIG capacitor bank

    This is what happens when 5kJ discharges into a transformer: http://i.imgur.com/finFJ.jpg Turns out all the damage was confined to the core, which pretty much exploded. Super glue fixed that up though, and it should work fine until I can find a replacement core from TSC international...

    BIG capacitor bank

    Diodes failed and the caps discharged into my new transformer. ...there ain't nothing left of it anymore.

    BIG capacitor bank

    Reasonable meaning...? New transformer done now. It's 220 turns of 24ga wire on the secondary, with a 16ga 4+4 turn primary, insulated with only the best masking tape I could find. There was a huge improvement in charging power: half wave rectified it charges the 24800uF 700V bank from 0 to...

    The hell is electricity?

    I thought about using water, but then I'd have to stick with it the whole way through. Second guide is done, thhis one is all about wire. Teravolt.org - Wire

    BIG capacitor bank

    $30 worth of solid bar got me one bank made, total capacitance is 24,400uF at 700V (5.4kJ!!!). And, I still have 40 something unused caps. I realized though, I'm going to need something to switch the bank! I don't want to splurge on a puck SCR because I'd probably kill the thing anyway, so I...

    BIG capacitor bank

    Almost done with the busbars on bank #1. Total is 48 capacitors, and I have about 42 good ones left to make another bank with. I ran out of aluminum to make that one with though, and I'll need to sell another tritium tube to afford it. I think I'm going to make a pneumatic contactor to switch...

    Trit tubes for sale

    Check OP to see what's left, and sorry I only take google checkout or usps money orders.

    BIG capacitor bank

    I don't have any SCRs... Hell if you were interested in x-rays I'd trade you a coolidge tube for that puck at any moment, or a neon sign transformer. My bank would explode a stud SCR so I need a puck, while yours could be used with a stud. @Cyparagon Correct. Skin effect applies to pulses too.

    Anyone have a a pair of 512MB SODIMM PC133 ram sticks?

    Think about it like this: How long have they been sitting on your shelf, and how long has it been since somebody came asking for something like that? :whistle:

    I still need ram guys... my computer is slow!

    BIG capacitor bank

    I ended up getting some aluminum stock at tractor supply. It cost me $30 for enough to make 80% of the busing, and I need to go back and spend another 10. Not too bad really, but more than I'd like to have spent. As for copper stock, that stuff can't be found anywhere. @Cyparagon Remember...

    BIG capacitor bank

    The hardware stores arounf here want $20 for an 8' section of 1/2" pipe! And no trevor, normal sized wire will likely explode, and I don't have 2ga wire. Hrm, maybe tractor supply has reasonably priced aluminum stock...

    BIG capacitor bank

    Well the stockyard won't sell me any aluminum or copper because "people can make bombs with it." I fear for the future of this country... ..but now I have 90 capacitors and no way to connect them :(

    BIG capacitor bank

    Well seems like all my metal is gone. :-( I have about 80lbs of lead left over from an x-ray experiment, maybe I can take that to the scrapyard to get some copper pipe.

    BIG capacitor bank

    I still need to build the busbar system and charger. I planned on designing my own flyback mode charger, since uzzor's boost converter would charge the bank a little too slow for my taste.

    No, there are actual photodiodes meant for x-ray detection! http://sales.hamamatsu.com/en/products/solid-state-division/si-photodiode-series/x-ray-detector.php

    Arrests?

    I'll admit that I will occasionally shine my laser into the empty sky, and I've received no hassle for it. I did however receive a warning from the police once, for shining a laser in my yard to adjust the focus. Fortunately since it was on my own property they couldn't do anything about the...

    Randomly recieved a free Arctic in the mail.

    Three rights make a left, and if you made a left you went the wrong way. :eg: I say keep the laser, knowing that company they'd have you send it back at your expense.
