Six Pack Tesla Coil

Introducing the 6-Pack Tesla Coil

I was invited  (and encouraged) to write an article for Make Magazine for an introductory Tesla coil project. This one is a simple spark gap coil using beer bottles for a tank capacitor and a small Neon Sign Transformer (NST).  It doesn’t play music it just makes loud sparky noises.

The article is meant to teach the basic skills and practices to build and tune a Tesla coil using common materials that are readily available. I wanted to provide enough detail and instruction so that a beginner would be successful.  The coil is made to be modular so that the maker can experiment easily and change out bits as they learn how to get bigger sparks out of their coil.  I hope to post a few improvements after the article gets out so folks who wish to, can get a bit more spark length out of their coil.

The print article will be 18 pages and will be in issue 35 of Make Magazine. The web version of the article includes more detailed instructions and is available here.

I hope a few people actually try to build the coil.  The interns at Make built theirs and were thrilled when they got it debugged and tuned up. Here’s a picture of their coil:

Note that they had to add a bottle to tune the coil so its even better than a Six-Pack!

Thanks to Sean, Keith and the rest of the Staff at Make for the opportunity to write an article.  I’m looking forward to the next, maybe simpler, article.  Thanks to Steve Ward for proof reading the article and making sure I got the technical stuff right.

A special thanks to Bart Anderson for his fantastic JavaTC program and his website. Its a great resource for coilers!
