I Have A Plan ;-)

[medunaweb]

Does anyone know where I can get a 20 to 30 KV PSU or generator? hehehehe I am aware of all the dangers involved but I have this great plan for a science project that my friends and I plan on doing in one month ( we sort of put it off for some time ). But I need to get 20 to 30 KV of power from something. I don't have too much money but I am willing to put money into this so anyhelp would be helpful.

edit
I was told that if I take a monitor apart the wires that go to the cathode tube can generate roughly 20 KV (20,000 volts) is that true?

lol... nice.. what are you planning on doing?
and i'd say that you could test the tube with a multimeter... but you'd need quite the multimeter to handle 20000 volts.

how many watts do you plan on generating?

this site basically shows what we are going to try to replicate but we are modifying the design to more of engine style that can hover vertically. Using a program that we have been developing we are going to try to make it so that it can stabalize itself without any help. So you could push it down and it will compensate for that on its own. That is the current plan but it might be a little to far for our time limit.

hmm... i don't have the time to read all that.. maybe tomorrow...
looks fun though ;)
and can you ever have more fun then when you're playing with thousands upon thousands of volts? i think not ;) :D ;)

Please don't post anything if you can't add to this thread. At least wait till tomorrow when you have the time to read it and then maybe add some insight to my question.

After that last post I doubt anyone will help.........
including myself

I can't stand the stupid responses I get from people who just want to up their post counts. I don't see how your post adds either.

[Korndogg]

i wasn't trying to just up my post count. though i admit it didn't add much to the thread. Dasenergi only has 67 posts... doesn't appear he's too desperate to get his posts up... and how did that last post of yours add anything to the thread?

[medunaweb]

I said atleast wait till tomorrow when you have time to read it all but I am trying to defend my reasoning for saying that and I could say the same about your last post as well.

I'm not sure but I think the voltage can be amplified within the monitor to produce 20KV. Why do you need such a high voltage? DO you need more voltage than current? Is there a target watt rating for this project? At 20KV I'd imagine you'll be using a current close to nothing, unless this thing sucks a bunch of energy.

If you want this to be somewhat inexpensive you could try looking for a bunch of broken TV's in a landfill or something and conduct the experiments with the charge left in those. Dangerous stuff though, but that's never stopped anyone :D.

yeah i want to try to keep the amperage low and I was going to try to use several monitors and connect them in a series but I beleive that will increase the current by doing that as well as the voltage. I will see if I can get some old TVs and try them too.

Just make sure you don't put the monitors and/or TVs in parallel or you'll get more current than voltage per unit.

posts in completely custom don't add onto your post count.

nice attitude :rolleyes:

the monitor flyback transformer output would give u a pretty high positive dc voltage (20k-30k if i recall correctly). you can find circuits on the web for driving flybacks (just search for flyback driver on google) if you dont want to use a whole minitor. most flybacks these days include an internal rectifier/voltage multiplier.
