I need a high voltage, high amperage power supply

I am in need of a power supply that can give out about 500V @ 13A. I know it's high, but I want it to charge a capacitor(400V, 1000μF, 13A) for my coilgun. I've already tried a flyback charger, but the result was to blow the capacitor up(I think that it couldn't withstand so much voltage, despite the amperege was lower that its threshold). I don't want that to happen again and I want a relatively fast way to charge the capacitor. Also, the power supply needs to be portable. Another thing: the voltage is not mandatory to be THAT high; the amperage also(let's say...1 or 2 amps...)... However I need DC pulsating current, at 20 kHz NOTE: I really hope that I'm not asking too much.......

wiring and grounding high voltage transformer?

i need to add another power cord to my HV Transformer it does not look like it has any difference in which way it is wired could i just connect the power cord to it and in the second picture is the screw the ground to the case or can i just gound the case itself to a pole in the ground for example

Why not get high voltage by boosting 300V to say 2KV ?

Hi, I plan to build High Voltage of 4KV. The output current is very low (say 100uA). I intend to use this as focus voltage in a CRT application. Hence, I am exploring the ways to do so. I have seen people building high voltage (8-20KV) using transformer followed by voltage multipliers. Now a days, MOSFETs are available which can withstand voltage upto 4.5KV. So it should be possible to create boost converter which could boost 300V to 2KV. Then one can further boost the voltage using voltage multipliers. The input voltage of 300V is achieved by rectifying the line voltage of 220V/50Hz. Visiting internet, I do not see anybody doing so. Hence I wonder what could be wrong in doing something of this kind. Could somebody elaborate ? Regards, Hardeep

Cheap High-speed Camera

I was wondering if any of you fellow Instructablers have a high-speed camera that you've lost interest in, and are willing to sell for a low price. Alternatively, if any of you know how to make a cheap, high quality, high-speed camera, could you post an Instructable? Edit: I bought a Casio EX-F1 a while ago, and even made an iBle about it.

Need help. How to ground high voltage.

Hello, I am in need of a little help. I recently purchased a small Holmes fan with filter as I had a coupon, it was normally 15 dollars, but the coupon was $10 off. When I first bought it I intended to convert it into a electrostatic precipitator, then when I got it home I realized it already had a built in ionizer, which simplified my idea as I can use that as the hv power supply. I am going to use alternating high and grounded metal plates in place of the filter. I was wondering what is the best way to ground the plates? The fan doesn't have a grounding wire.

Micro High Voltage

I'm going to attempt to make a super micro tesla coil that is 100% contained (unless it runs off of like 12 volts dc, then I'll use a wallwart). Of course, one of the i biggest problem is the power supply. So this is what I'm asking, what's the best way of ramping up the voltage? A tiny toroid transformer? An inductor that gets pulsed? Voltage Multiplier? Something with static electricity? Some type of Inverter? Using Greinacher Cascades? A marx generator hybrid? Other stuff I havn't heard of?

High Voltage Ground

I'm starting to work with high voltages again, but for real this time. I just built an ignition coil driver, using a 555 (and I got an ignition coil), but my 555 broke (the texas instruments ones can only drive 15mA, oppose to the normal 200mA, oops) so I have to go buy one today. My main question is what to use for ground, whether it be for an old screwdriver for arcing sparks or the secondary of a tesla coil. I was originall just going to use the 3rd prong of an outlet, but somewhere on the internet I heard this could destroy all surge protected power strips and destroy all plugged in electronics at your house. I, of course, do not want this cause... well... I'd be screwed. Is this true or not? Can I use the 3rd prong?

What should I try taking high-speed photos of? UPDATE1Apr10

I took the two photos below last year, and I want to try a few more for a new project. My rig is simply the flash unit out of an old disposable camera, rigged up to a microswitch. For the falling coins, they landed on a tilting platform with the switch underneath, so that the first coin to hit bumped it down into the switch and fire the flash. The droplet was just by setting the faucet to drip and poking the switch manually and getting a lucky shot. I'd like suggestions for what to try photographing next. I'd prefer something that can activate the flash by simply pressing two contacts together (i.e., a switch), as I haven't had much luck building light- or sound-activated triggers. UPDATE so yeah, I totally this in before spring break and forgot to mention it. The project was a magazine cover, don't knock the radd grafics dezine skillz.

Engineering Class Suggestions

I'm part of an Engineering Club at my school and we're looking for future projects that just explore some ideas of Engineering in general. We would like to come up with our own ideas at some point, but for now, a lot of us are inexperienced, so I thought I could come here and find some stuff. So far, we have decided to build a bunch of Stirling Engines and use them for miscellaneous things, but after that, we have no other ideas. Could you guys come up with some ideas (possibly your own or ones that you have done), that are similar to this idea of teaching the basics of making things and stuff like that? Links would be helpful. Guidelines: Because we do this at school, there are certain rules that prevent us from bringing large knives and laser pointers on campus. Power tools and exacto knives are OK, though (IKR?). Also, because we are students, we have to scavenge around for materials, so unless it's less than ~30$, we might not be able to do that either.

I heard disposable cameras use high voltage for the flash. so if you were to take out the capacitor from 2 and plug the lead to the flash from 1 camera into the battery holder for another you could keep putting them together to get higher and higher voltages right?
