Where do I get the bobbin for the transformer and does anyone know a good source for the magnet wires?
Also, what constitutes high voltage wire? Can I just use some thick wire?
I'm gonna build this as a project for my physics class.

capacitor values for C3 and C4
Sorry about the typo in the article.
The correct values for C3 and C4 are actually .01 uf at 1.5KV DC or higher, ceramic disc.
Take care, Karl

re: original poster
Hey there all,
I'm building this project and am glad to see the original author chimed in.
To the original poster, the article mentions that you can find transformer parts in common items such as these new "green" incandescent light bulb-replacements. Each one of these fluorescent units have there own power supply.
The power supply methods and component methods vary from unit to unit and size to size. I had to take several different kinds apart to find the right size transformer.
In the end, I went with this bulb, a large one I found at wallmart.

Re: Coil Launcher Parts
I had to search hard for HV wire too, until I realized that standard multimeter lead wire usually has a higher voltage rating than regular 600v hookup wire. The deal is that heavier insulation is needed for higher voltages, larger gauges for higher current. You can take apart a TV or something to obtain a short length of 30kV rated stuff, but that has its own dangers.aerohoff wrote:Where do I get the bobbin for the transformer and does anyone know a good source for the magnet wires?

Just find a meter lead wire with a tolerable rating, maybe 1500v for this design.
Concerning magnet wire, if you live in the states there are several onine distributors of such wire.
If you're still looking for it, I'd give you a link or two..
Re: Coil Launcher Parts
afarawayland, I'm glad to hear someone else is trying this one. Did you get it to work? I found all the parts, but I didn't get it to work -yet. I tried to assemble the circuit on a crappy protoboard from radio shack, which was a horrible mistake. It was very difficult to follow the layout without a plan and the pads on the board didn't survive the quickest of soldering. This was the first circuit I've attempted to build this way and probably will be the last.
I haven't gotten around to it yet, but my next attempt will be to solder the circuit together directly on top of the schematic from the magazine. Once I get that working I will design a pcb for it. It's about time I get back on this project so I'll post some picks of my failed attempt later this week and keep you updated.
Please let me know how yours turned out.

I forgot. THANK YOU KARL! for the great article.
