I just got a plasma ball and want to put it in my case. It says that the power adapter has an output of 12VDC @ 1200mA. Can I just wire it to the 12 volt wire of my psu? Thanks, I wanna be sure what I'm doin before I break it
I meant how do I tell which wire is ground and which is power on the circuit of the plasma ball. Any ideas?
What does the power adapter jack look like? I am assuming it looks like a hollow tube, with the plasma ball having the "male" center plug? If so, that male center plug will be the positive while the outer portion of the jack is the ground. You can verify this with a multimeter on the power adapters jack. Don't have a multimeter? Stop what you are doing and get one.
Test it and whichever combination doesn't result in a shock or explosion is probably your best bet Have you taken the ball apart? If you open it up, there might be some labels on the PCB or something. EDIT: Shadowspawn posted right before I did! His informational post came before my slacka$$ed answer. My fun is ruined!
Don't forget to sheild the plasma ball from the rest of the PC Use a wire mesh, or foil connected to ground behind the plasma ball.
Dammit Zap you're no fun. I was waiting for the cries of "OOOH my plasma ball fried my hard drives " No seriously thats a good idea
Depends. You have to make sure said mesh is a reasonable distance from the ball surface (say, about an inch), else all the pretty glowy tendrils emanating from the central bulb (anode) will make straight for the mesh. Sort of ruins the optical effect.
Thanks cpemma, i had that same idea....workin on it now. not like so many others say and havent actually thought of it. I'll get to the point u absolutely ruined me, i thought i had such an original idea and when i saw that link not only is it the same idea but its the same friggin case! i couldnt believe it. anyways, i thought the yellow wire was 7volt? i hope i didnt juss wire my 6volt plasma ball to 12v.
Hey, I have the high-voltage circuit that I ripped out of a 4" plasma ball. Its connector jack for the wall transformer has 3 pins -- one is ~12VDC, the other two are 0VDC. Does it matter which of the two 0VDC pins I use for ground? I'm an electronics n00b, so please be gentle! Thanks! Oh yeah: I'm in the US. But I don't think it really matters by the time you get to all that fantastic DC stuff from the computer's PSU. Ah, what do I know?!
