Another very interesting project Andrei. Thanks for taking the time to create and share it. I'd be interested to see what improvements you come up with in the future.
Just a thought to increase the number of turns: Create and stack several boards. The coils would start on the inside of the top layer and spiral out to the edge, cross over, then spiral back in to the center on the bottom side. There would be a hub at the center on each side of the boards. So, now you could just stack the boards in series, with a metal separator joining the hubs. For this, I'm imagining a nylon threaded rod, with metal nuts between the boards. The primary could be on a separate board or just a plain wire winding.
I've actually reverse engineered the original Chinese pancake Tesla coil, and I've found that it and a lot of other similar coils use a push pull class E topology to push high pulse powers to the primary and create large arcs for their input voltage. The only hard part about this circuit is tuning it since you have to control 2 capacitor values in order to get a nice class E waveform and high power output. I still haven't figured out how to tune it mathematically so how did you tune the circuit?
So I'm working on a project and about to make my first PCB order. Struggling to understand when I should used SMD vs THT. Also are there options from PCB way to have components mounted or solder pre applied? Concerned I don't have the fine motor skills for soldering SMD's by hand. (Love the content... keep them coming and thank you!
@@ELECTRONOOBS I think gold is used not for the Conductivity but for the protection of Cu pads from atmospheric oxidation corrosion otherwise Cu is above than Au in electrical conductivity table.
No, but it will help with heat and current handling. . The exposed tracks can be covered, or you can just have a clear mask used on the top of the board fully over the mask and using a screw apx 3.8-4in long with a 3/8's nut on top will add just enough capacitance to pull the resonator into tuning and max out the arc. I built something like this a few years ago at a much much higher base frequency of 40khz and honestly the resonator on this is pretty low. The advantage of the 40khz I used was very clean and clear audio. The downside was that the ozone production was pretty high with 6in plus arcs. I do a lot of planners magnetics for power supplies and filtering at work
@@orphax1925 if they leave the PCB with only copper they would oxidize very fast. So they bath them in tin or other materials to keep them from oxidize. Usually tin, silver or gold. That's why the PCB pads are not copper colore but metalic.

Hello, I watched your Nixie Tube hand watch video and now I'm wondering where the second part is?
Please make new contests in your website, it was very fun to participate back then
It was very bad for me. It got full of spam accounts .. :(
Hi, I like your staff
@electoboom you may like this Tesla coil
Sir please make powerful like online products please 🥺
Men if you can make project of mini injection molding machine !?
I wonder if u can make a reciever to turn it back to music? Xx

Eyeball it trying different values. Is not perfectly tuned but works ok...
How did you add the loops...it must have taken a lone time

Generally THT is good if you're just starting out or if you don't have tools like a hot air station that are good to have for SMD
Why gold instead of silver since silver is good conductor!
Gold immersion is a bit cheaper :=)

your video upload is connected with great scott's?
it is the first flat tesla coil
its good but not the first.
Check this out from @PlasmaChannel from 1 year ago
"⚡Building This Tesla Coil CHANGED EVERYTHING (HUGE 3D Lightning)⚡"
do we need to expose the tracks on coil pcb?
Yes, the PCB has exposed tracks otherwise they would be covered by solder mask
@@ELECTRONOOBS Thank you
@@ELECTRONOOBS is it necessary to be golden track?

Great 👍.... Thank you for providing information
7:58 That's not the right type of thermal pad to apply onto a mosfet. They have their dedicated type
True, it was just to show an example.
gold is not more conductive than copper
Bur is better than tin which is usually what they use for the surface finish :)
@@ELECTRONOOBS oh ok I didn't know that, thx !!

First
Gold is a WORSE conductor than Copper and Tin. Only Silver is a better conductor than Copper.
Actually gold is better than tin which is what they usually use for the cooper finish. Yes, silver finish would be better but is a bit more expensive
