At work the other day, I got the opportunity to teach a class on inductance and resonance in relation to electronic circuits. So of course, I thought a tesla coil would be the most fun visual instrument to instruct with.
Of course, the inexpensive kit I bought off of Amazon came with a small slayer-exciter circuit, which is a little different than the traditional tesla coil circuit, since it finds it’s own resonating frequency, but it was still impressive to watch. We even burnt a few scraps of paper and then used the spark as a plasma speaker, which was pretty fun too.
We also had a few florescent light bulbs around, both straight and round. So the question became: Star Wars light-saber duels, or Tron disc wars?
