OneTeslaTS Tesla Coil Kit

[KG7AMV]

Customer dropped off a OneTeslaTS for me to assemble. PCB seems to be good quality some of component's from the kit well could be better for what they charge!

Some of the solder pads are so small hard to tell if getting a good flow some holes for the component leads could be larger some are tight fit! But it is a $400.00 kickstarter project.

I'd be very interested how to get

sparks two feet long

with a 6.5" coil.

No Idea how to get... you may want to contact OneTesla.

Why not? Or do you think that the arc should take shortest distance between the top and ground?

Only thing i have a recommendation for them to fix for a DIY kit is the quality of parts, larger solder pads on some parts, and larger hole diameter's for the diameter of leads some are very tight! SMT on 2 resistors for sure! Or space it out for standard thru hole Mounting!

Yes. Although I suppose it might be possible to insulate the entire unit including power cord but that does not seem to be the case.

Hello, The rather large topload (donut) guides the arcs away from the coil it self. They typically strike the ground a fair bit away from the coil. If you would plot the field strength using femm or something like that you'll see sparks will always start at the side of the donut, not top or bottom. You also notice that the spark is not likely to go to the bottom of the winding.
I build several tesla's but i never got further than 2.8 times the coil winding length. But 3 is doable as far as i know.
Longest arc i made  sofar is 8 meters

So we agree as I originally commented that 2' arc with a 6" coil is impossible. In fact even 18" unlikely.

Yes we agree sort off. The shortest distance across the coil is definitely not the maximum spark length and that's what you seem to imply. No need for insulating the case or cables. electrostatics do the job for you.
This is a dual resonant solidstate tesla coil , drsstc, they usually perform better then the sparkgapcoils i build. so 18 inches sounds good but 2 feet nah.
In the video it only shows roughly 12 inches though.
A reasonably new disign actually does much better as 1:3. The qcw coil 1:5 or so. But they look alot different and they can't do midi music and so on. just very short bursts. Definitely not this coil.

Varnish the coil!! Not a fun task if I were to do it again I would use a sponge brush but never varnished such a large coil.

My Lathe is not set up with a VFD and 70 RPM is the lowest it goes that was a bit to fast and did not want the urethane all over my lathe so I use the BBQ rotisserie and as fine of brush as I could find local HW Store. Now have a headache from the fumes even did it outside.



Interrupter Done and Powerd Up! Case they Provided did not fit.


But the Lower Section is Coming along nicely finish the coil and fire it up.


So far to many hours in this gadget! I guess he has another one also?
