Excellent work Finn!!
and thanks for posting and documenting all the stages of your project!
this is truely a great thread with some much needed additional DRSSTC info
into why and how delays can cause 'spike' problems in high powered coils.
Your 'Predikter' circuit seems to over come this.
once again.....well done Finn and Daniel too!

Thanks, Mel.

I learned this approach from Terry Fritz. He said it was the easiest way to keep records of the progress of a project.
Other good reasons are the valuable, and at times indispensible, input from other coilers, as well as being part of a big rush towards the holy grail of solid state tesla coiling: zero current switching.

We will meet in Cambridge this year, I think?

Cheers, Finn Hammer

Nicely documented. Great to learn from and maybe even find a way to improve on. Think it will be sure some variation of your driver will end up driving my quad CM-300 coil. So yes you'll have a coil to compete with in the EU tongue
