I've been thinking about adding these to a machine. I'm guessing that the best way to wire these in would be to use one of these?

Ya, I understood the service outlet part when I PM'ed you. But the smaller ones for pop bumpers run on 3 volts. The smallest "Wall Wart" (I was unfamiliar with this term when I PM'ed) that I found is a 5 volt. So again, my question - Wouldn't this work best since its adjustable to 3 volt?

I dug through a box of wires and plugs from various elsctronics in my garage and found a 3 volt "Wall Wart." I guess I'm in business. I also picked up 3 2.75 plasma discs. I'll play around with it and see what I can do. I'll need to get just the discs off of the battery unit on each piece. This shouldn't be too hard. Then I'll wire them in series and see if they'll work for me. I think they might look cool on my Tron when I get it later this month.

By the way, thanks for the help!

I'm going to play with them first to see if I can get them to look good after chopping off the basster cases (If they won't just slide off). Then I'll have to wait for my Tron to get here. I'm kinda 50/50 on whether these will work and whether they'll look good in my machine. I'll post when it all comes together and what I could/couldn't do.

Ya, that's what I mean. Thanks again for your knowledge!

Got em and posted what I've found:
