Hi, Everyone,

In this video, we learn about the engineering and story of the QCW Tesla Coil Gun designed by Steve Ward and Phillip Slawinski, and built by Cameron Prince of ‪@teslauniverse‬and then we see it in action! Big thanks to those three guys for making an incredible device. It's challenging enough to make a QCW Tesla coil but to make it portable? Nice. Let me know what you think of this video in the comments below. This video has been on the shelf of my computer for a long time, edited off and on with lots of my time spent being intimidated by the task of editing all this footage together into something informative and entertaining. Well, I'm so glad with how it turned out. Check out the resources below to learn more about tesla coils and the fascinating history and people that made the tesla coiling hobby what it is today :) All music in the video was made by my good friend, Jason Palafox and it was me rapping in the PCBWay ad haha.

Thank you to PCBWay, use my link below to order PCBs and it also supports my channel!

Appendix by Steve Ward:
"
5:30 the blue block component identified as a "relay" is in fact (not a relay) a DC current sensor board that feeds the realtime battery current information into the UD3 controller. FYI, the peak battery current is ~150A on this design despite the smaller fuse and breaker ratings.

11:50 the precharge relay is controlled by the UD3 which has voltage measurement capability it automatically switches out the resistor based on the % charge of the bus cap versus the battery. It also stops the gun from working if the battery voltage is too low.

16:55, they are 33nF 1600VDC Metalized PP Film caps. They are arranged 14 series by 4 parallel strings so the total tank cap is 9.428nF.

~23:00 , Cameron misspeaks and says I made the gunmounted controller (not so). This is actually just a modified version of Phillip's "MPTCC". The trigger signal for the UD3 was a special feature for the gun and is specific to QCW mode so that you could trigger the sparks instantly. The gun is actually capable of regular DRSSTC operation, but it's not recommended to use regular mode because the sparks will branch and shock the crap out of the operator. The high pulse rate sparks really hurt...

Also, yes, the cooling system was absolute overkill! The only benefit was that it allowed the IGBTs to be packed tighter together which provided better electrical performance, slightly."
