Thanks Jay, I just hope the end product turns out alright!

@@LabCoatz_Science Any update? Just found this channel, really enjoying the content!

@@StormBurnX The coil itself is mostly complete, but the driver has given me some trouble. The driver I designed ended up failing, so I'm switching over to the UD2.7C by Loneoceans. A friend of mine is doing the PCB assembly, since I have little experience with SMD and don't want my first attempt to be on such an important circuit, lol. It should be arriving in the next few weeks, and once it does, it should be pretty smooth sailing!

@@LabCoatz_Science Here's to hoping things go well! Your consistent dedication to quality is delightful

I just hope it works properly, haha! By all accounts, it should, but you can never know for sure the thing is built and tested!

@@LabCoatz_Science that's for sure haha!! I'm sure you will get it 😁⚡️⚡️

I looked into the UD+ when I was designing this coil, just because freewheeling sounded like a cool addition with the 1ms+ on-times, but $150 was just WAY too expensive for a single driver in my opinion. I could probably build the same circuit for $100 or less, if I had the schematic. Without counting the fiber optic units, which are like $30 a piece, my driver and interrupter combined should cost less than $60 to build (that's including the PCBs and shipping) and perform almost identically to the UD2.7C. The IGBTs and capacitors, however, take the total up well past $300, lol!

​@@LabCoatz_Scienceyeah I completely understand that. My driver was the most expensive single part for me. I don't really regret it though. Eventually I need to assemble the ud2.7c pcbs I have and use the UD+ for a large coil I have in the back of my mind. I'm excited to see you get this thing running though. I hope it lights up with no issues 🤞

Haven't tried QCW yet, but I did finish this coil, and I'm hoping to have the final video out sometime this week (assuming the sponsor cooperates, lol)! The coil ended up around 60kHz, and with 680VDC on the bridge, it can easily crank out 4' arcs. It seems happiest around 100us and 200 BPS, and I'm sure if I plugged it directly into a 240V outlet instead of my 240V transformer (which probably gets really loaded down) I could hit 5' or more! I had to use the UD2.7C though, since my driver failed to operate. Overall it's a fairly solid DRSSTC!

@@LabCoatz_Science That sounds awesome. You kind of reminded me that I need to rethink the lowest freq possible with bricks. Any idea if the ones you used were like "legit" from a distributor or maybe more like ebay specials?

@@Magneticitist I just bought them second-hand from "All Science", who has built his own DRs with them before. I looked up the part number and they seem like legit Mitsubishi CM300s!

​@@LabCoatz_Science Man you know it's a really tough one cause the only real way to know you're getting a legit half bridge module that can handle something like 300A+ continuous is by dropping like $300+ on just one module. China has gotten so good at counterfeits that I'd bet people with their aliexpress deals are simply not pushing their builds far enough to where the counterfeit smaller die size etc can't take it. If one were to assume like a 1/2 size reduction then I suppose just buying two $50 bricks vs one $300 brick is still a better deal.

@@LabCoatz_Science I keep forgetting the strides in semiconductor advancement these days 😂. For your next build I recommend trying something like new miniblocs. I'm going to try these out instead of using older slower bricks I grabbed from old VFDs. IXXN110N65B4H1. Like 30 bucks a piece ain't bad and that's from legit sources.

You have to order it for yourself using the Gerber files provided by Loneoceans. However, there are a few pre-made ones floating around on places like eBay.

Loneocean's writeup for the UD2.7C is really good for that. I could've gone into it, but the video would be well past 20 minutes at that point, and there isn't much you technically need to understand in order to get a DRSSTC running with it (besides what I already mentioned about the feedback windings, OCD setting, etc).

Styropyro actually made an excellent video talking about why Tesla coils don't kill you! Some people say it's the "skin effect" (that the high frequency electricity travels along your skin and doesn't penetrate deep enough to hurt your organs), but this isn't actually correct. Same for the low current myth: many modern Tesla coils can actually output hundreds of milliamps of current! The short answer is that high frequency electricity doesn't tend to affect your nerves very much, so it's almost impossible feel (unless a Tesla coil is interrupted, in which case you might feel a bit of a buzz, but nothing dangerous). You can touch many Tesla coil's safely, but larger coils can still hurt you: interruption kinda makes high frequency electricity "appear" like lower frequency electricity to your nerves, so there is some risk of shock. Additionally, if you touch a strong enough coil for long enough, it can lead to burns. In general, most Tesla coil arcs less than 24" long are fairly safe to touch. I say that because I personally know people who have been zapped by coils with that kind of output, and it caused no serious harm. But with arcs longer than about 1 meter, it's hard to say what would happen...you probably wouldn't die or go unconscious, but it wouldn't feel very good! Hope that answers your question!

@@LabCoatz_Science Appreciate the info. I've watch some of StyroPyros stuff but must have overlooked that vid. Yeah I've touched em in lab classes etc, but learning about some stuff it seemed like the kind of thing to ask. With TCs can they only output electricity, or can they take it in via some sort of daisy-chaining of one TC to another nearby?

@@djdrack4681 If you have a coil nearby (especially one with the same resonant frequency), it will indeed develop a voltage! I've actually seen demos where somebody places two coils next to each other (one power and the other not), and the unpowered coil produces sparks! However, for wireless power purposes, it's not a very good option: only part of the energy actually makes it to the other coil, and then you have to worry about stepping it down again with another tuned primary circuit (which would technically be the secondary in this case...it's weird, lol).

@@LabCoatz_Science it isnt just skin effect. make a tesla coil from a ZVS driver. just a little one. touch the coil. i guarantee you wont ever let that arc strike you twice. not too worry, they barely make any lightning. what they do do when they draw an arc, is pump as much power as the supply can deliver into that arc. volts and amps mean nothing, its all about impedance and the amount of power that can be transferred. the voltage across the arc is only quite low, but the power is what makes it so spectacular... a ZVS is a parallel resonant circuit, it always stays in resonance regardless of changes in inductance or capacitance, and its power draw is only limited by the loss, which in this case is the arc... with no arc, the resistance of an open circuit is huge, and then its multiplied by the turns ratio squared. a tesla coil usually being about 100:1 or higher, that makes for 1:100 from secondary to primary, and the square is 10,000... so the resistance the power supply sees is huge, and barely any power flows. you dont get amazing light shows from a ZVS driven tesla coil. you do get extremely hot, painful arcs that give you RF burns and melt secondaries. they do work fine when used as a power supply to drive a spark gap. just dont use them to drive the secondary directly. when the secondary is shorted, the resistance drops to nearly zero. and now, the power supply sees nearly zero resistance, and will try to deliver everything its got into that resistance. as an arc is drawn, voltage creeps up to some low value, and the arc makes lots of heat as lots of power is flowing through it... this is much the same as what is happening in a microwave transformer as well... theyre unregulated, and when you short the secondary, all the power supply, in this case the main grid, sees is this resistance... at the multiplied (or divided by!) the square of the turns ratio.. it means that if you accidentally bridge the gap with say, your finger, that at 2kv is a few mm or so of air, then as soon as the air ionises and an arc forms, the power will only be limited by the resistance of YOU. (ignore the coil resistance. gets weird when its higher... usually its orders of magnitude lower...) whereas i will happily let a spark gap coil play its display over my fingers without so much as a whiff of singed hair, despite it spitting out 1meter arcs. in this case, the neon transformer is specifically designed to only deliver 30mA when its shorted out. it will only deliver 15kv when open circuited. its voltage drops right down when it shorted. the conductive gas in a tube is a very low resistance, offers no impedance to current flow... so the transformer must limit it. the current will never exceed 30mA, and as it does, the voltage simply sags, so applying ohms law, everything still ends up balancing out... neon tubes are intended to be run 24/7.... and the tesla coil... it again, is so looslely coupled, that teh energy just doesnt transfer from primary to secondary, and with a spark gap type... the supply CANT just deliver power into the load, all it ever sees is the need for the capacitor to be recharged on every cycle to make good the losses.. so, the MOT... its tightly coupled, designed specifically to deliver power, and lots of it. it has the potential to reach 2kv (usually) but when shorted that voltage drops and the current soars... like wacking a nail with a sledgehammer. effective. whereas the tesla coil... as soon as it draws an arc its over, the energy being transferred is irrelevant. an impedance mismatch. like trying to hammer in a nail with a ten gram hammer with a two metre handle made from noodles.

@@paradiselost9946 I already said it wasn't due to the skin effect. My point stands: the reason it doesn't shock you is because the frequency is too high to effect your nerves, but it can burn you if you aren't careful. This is why you could touch hundreds of milliamps of high frequency electricity (from a Tesla coil, flyback transformer, or other HF ferrite-core transformer) and only receive burns.

Glad you liked the video, but a thousand-foot spark would require a VERY tall tower to keep the arc from grounding out prematurely, as well as several hundred kilowatts of power. It also wouldn't really vindicate Tesla's wireless power system, since the Tesla coil by nature can only transfer about 20-50% of the input power to the secondary coil (as indicated by the coupling coefficient). This makes it wildly inefficient, even with the best theoretical receiver, hence why nobody had properly implemented it into the power grid.

@LabCoatz_Science with all your knowledge and skills intact, all I'm saying is Tesla designed his system to NOT radiate out, (obviously there is some activity nearby it from high oscillation or breakout).. But he said in a formal courtroom questioning among stenographer, You would get only 10% of the current energy by ether disturbance... but 90% by direct waveguide connection. To add, he remarks that what he termed the dampened wave, (either quenching spark, which he could interrupt higher than needed, or breaking the resonator to ground) Said that 1kw could yield 5000 kw, whereas the continuous wave would only yield 1kw. It's said that using the Extra coil resonator beyond 1 kw input is where the 3rd coil acts beyond normal operation, which acts as its own series resonant circuit, but tuned as a topload object. Giving 2 separate 1/4 wave rises. Not 1/2 wave. I don't yet have that ability, and my objectives are different. See Kapanadze 100kw 2007 demonstration Turkey. I can give you all schematics. And I must say, Electra runs just so nicely, you're very skilled
