Hi, I'm trying to make a small tesla coil for my science project. I'd like to make something with at least 10 inch sparks but stay under my budget of about $100. I'm looking at buying a 6kv 21ma neon power supply with an AC input for $40. What are like they key parts I need and could I get recommendations on where to get them. I'd like to know if what I have planned is plausable. Also, the project is due in ~10 days so I have to work quickly. I don't understand what kind of capacitors and how many coils are needed for it to function.

I dont think you'll make it on that budget, after buying the NST the $60 probably wont get you far, unless you have stacks of electronics stuff around the place you could get components out of. If you have to start from 'scratch' I'd say you wont have a chance of making it with <$100.

I think you could make it for a hundred bucks, but 10 days may not be realistic, assuming you have other things to do in that time ie. school, homework. Parts can be taken from scrap. Wire for secondary from microwave fan motor, primary coil from an old fridge, caps from...mmm...lots of old monitors or TVs? Or of course there are always salt water bottle caps. Toroid can be a baby's toy wrapped in foil, or a couple of bowls. A junk coil is easy enough, it's the time spent to make it then tune it that is lacking. How about making a fly back driver, or you could just get the transformer and make a Jacobs ladder.

How important is tuning? Do you have to tune it for it to work at all or to maximize spark length and such? I was planning on obtaining parts through out the week and spending the entire weekend putting it together. How many old computer monitors would I have to break into to have enough capacitors with my transformer?

Thanks for the replies guys. You were right, the transformer I planned on buying won't work for my tesla coil. Where would I get a small iron core transformer?
