A new article has been added that describes the thoughts, design, construction and test of a very high impedance primary circuit QCW DRSSTC, where the voltage ramp is coming straight from half wave rectified mains supply and a mains synced interrupter is used to trigger at the right interval.
The article covers the fall pits and strange behaviour of Tesla coils driven in this manner.
The project is highly experimental and the results were not as satisfying as expected, but problems with switching transients was a much bigger issues than initially thought of.

Learn how to build your own Tesla coil and how to make it play music through a MIDI interrupter that can connect a computer to your Tesla coil in order to play music from just the sparks alone. It can be a hard start to build a Tesla coil if you have no prior experience in doing so, I recommend that you watch my video on how I learned to build Tesla coils and the history of how I started by building small Tesla coils up to my very large Tesla coil that can make 4 meter long sparks and play music while doing so. Besides the guide that I have listed here above, I have also developed a good deal of tools that can help you design and check if your components can be used in a Tesla coil. It is important to stay within the physical and electrical limits of the components, else you are at great risk of damaging them due to Tesla coils pushing the components beyond their specifications in order to get the longest sparks for the least amount of money.
