So I had a better idea… and as far as I know there is no restrictions on entering twice.
This time, I needed some thing more impressive. I’d been tinkering with a demonstration of lighting a bulb with a single connection for a while, so I tied it in with that. Unfortunately the only (working) tesla coil that I have that has enough power (actually RMS current at the topload) is the Aetheriser. So that is the coil I had to use.
A quick test with a long filament lamp proved the idea workable, but the free connection got a bit warm (e.g. too hot to touch) so I added a brass ball protection to the free end
The large ball on the other end gives stability and stops the lamp from falling over.
Earlier this month it was my great honor to be invited to demonstrate the PI zero tesla coils at the Royal institution Christmas lectures.
The Christmas lectures were a Christmas institution when I was growing up and they formed a great part of my education, especially the ones by Eric Lathwaite. This year is their 80th televised Christmas Lecture, I’m sure in that time it has inspired the lives of many many children to investigate science, and long may it continue to do so.
Behinds the scenes at the lectures was incredible, the organised chaos that was happening was untrue. There were 20+ experiments in the lecture (the first of three) and moving them in and out of the theater was a very well choreographed scientific dance.
I have every admiration to the RI and Windfall Films that produce it.
Walking in to the theater and standing where Faraday and not to forget, Tesla himself had lectured, I can’t explain the feeling. Oh, and the 350+ kids watching you… No Pressure…
The theater is incredible, it’s so much smaller than it looks on TV, add three cameras, a lecturer and 10+ support staff (dressed in black), it doesn’t leave much room for demonstrations that need a couple of meters exclusion zone for safety.
What will be featured on the lecture on Boxing day, not a clue, as is usual with any filming, its down to the final edit.
Even if I don’t make it on to the show, watch anyway well worth it for kids of all ages.

If you wire two boards together (wire the two sounders together with a long bell-wire cable, be careful to get them both the same way around) you can make a telegraph system with a button and sounder at each end. Then you can practice sending and receiving for real….
A test of breakout points made almost entirely of Strontium. The idea is that rather than containing the Strontium in a tube that needs to withstand the heat of an arc, we make a breakout with as much Strontium as possible. Of course Strontium is quite a good insulator so we need to add in a conductive component and something to hold it all together. This test uses PVC glue as the binder and bear conductive ink as the conductor.
Initial tests on a large rotary classic tesla coil
Some effect, but not as strong as Id hoped. Although the one on the chicken stick wasn’t bad.
SSTC 1Kw Much better results.
A great improvement on any other methods that I have used, and better still, the breakouts seem to be quite resilient and can be used multiple times.
