Finished my musical ZVS driver after 8 months of designing and learning! from electronics
I decided to start studying electronics at the start of the pandemic, with one of my main fascinations being high voltage. I wanted to make a taser, and thought all I would need was a capacitor. I quickly realized how little I knew, and started studying incessantly in the free time I had in between shifts at my regular retail job. Since then, I’ve learned so much, and it honestly is thanks to you guys knowledge, expertise, feedback, and encouragement!
This project has been a little over 8 months in the making; I was first inspired by Franzoli Electronics and what he was doing (the circuit was not copied from him, but I didn’t know you could make sounds with arcs). In pursuit of high voltage, I found lots of info pointing towards a “ZVS” circuit. After building a couple, I decided I wanted to try and design my own ZVS driver using a FET driver instead of just using the natural oscillation. After lots of trial and error, I FINALLY the design right for the purple PCB with the LEDs on it. When I was adding a button to turn the enable pin on the FET driver on and off, I forgot to add a debounce circuit; this caused the circuit to oscillate on and off at an audible frequency very briefly. I hadn’t realized I could oscillate the entire circuit on and off, with it still being audible, even though the ZVS oscillation is well above audible (100Khz). So I decided to design a zero cross detector to test it with a 3.5mm jack, and it worked! After refining the zero cross detection circuit for about a week, this is the final result! It is extremely efficient; none of the components heat up at all and all of the 80W it draws appears to go into the arc. I couldn’t be happier.
Thanks again, everyone! Hope you enjoy!
I would love to see something like a piano made out of these, health concerns be damned.
i want this
Si cool, Which is the song ?
That’s bad ass! I love the way it sounds!
The smooth camera work of the video made me think it was a sim or VR at first.
This is even better than a basic tesla coil great work
What’s the original song’s name ?
I wonder how much O3 this generates.
To OP and anyone else who worked on this, make sure to bring this to any interviews you go for. Bring it, demo it, and talk about it. If you are able to properly describe the steps you took when designing this, what worked and what didn’t, why something didn’t work, how you designed that PCB, what assembly looked like, and pictures of it, you will be above and beyond a vast majority of other applicants very early on in your career.
Plenty of ventilation please!
what camera are you using to record?
Your local ham radio neighbours might like a word!
Now play Daft Punk – Aerodynamic
At first I thought this was in a video game lol, what resources did you use to learn?
I’ve seen comments where you need to be careful of RF burns. Is that a thing?
MegaMan time!!
I could probably put something like this together. But I have worked as electronic engineer on a professional level for 22 years…
This is an amazing result efter 8 months! This type of progress and capacity to solve problems and find a way forward is what I always look for when hiring people. What you know when you start is not very important, but how you develop that’s important.
Great work!
this is very cool

What song is it? Also, REALLY cool. I now want one
I’ve always wanted to build one of these! That’s awesome!
