- After spending the last seven years working my way up the Tesla coil food chain, I've finally completed my very first true DRSSTC, and now it's time to test it!
Coil specs:
Secondary coil: 6" acrylic tube, 16" winding height composed of 34AWG magnet wire coated in epoxy. Roughly 60kHz with the 16" topload.
Primary coil: flat "pancake" coil with 8.75 turns, 16" outer diameter, 8" inner diameter
Resonant capacitor: 0.25uF/6kV bank of fifteen 942C20P15K-F Cornell-Dubilier capacitors (five parallel rows of three in series)
IGBT inverter: CM300 full-bridge, 1uF/800V snubbers on each module
Bus supply: 680VDC voltage doubler made from two 3300uF/450V electrolytic capacitors and an IXYS 1kV/30A "mini-brick" twin diode. Takes 240VAC (or 120VAC for 340VDC on the bridge).
Driver: Loneocean's UD2.7C, powered by a 24V/5A power supply.
Interrupter: based on Steve Ward's burst-mode interrupter, but without the burst mode. It can reach 280us pulse times, but I never push the coil beyond 150us. Typical BPS frequency is around 100-200Hz.

That's impressive arc length from a coil of that size, but CM300s are beasts of igbts. You can definitely set the current limit to at least 1kA, and crank up the on time as high as you can go without tripping the OCD for some insane arcs. Great coil!
Congrats!! The coil looks pretty and neatly built. The output is AWESOME!
Despite I have dropped the research on the Tesla coil and most other physics projects decades ago (To all-in in chem), the Tesla coil still remains the most fascinating physics project in my heart.
It truly is a fascinating piece of history but it's also science and one of the greatest inventions in the world!
awesome project. The fire and electric arcs looked amazing.
this was probably the most fun tesla coil video i have watched in a while. the experiments are so cool. especially the fire breakout point and igniting propane! Also nice that there is no music blasting on the background when you are talking.
That's too cool maestro!
i knew you had something like this in the works. nice dude.
wait you did this while in college..... @15:16 I am pretty sure i have dyslexia and have to work really hard to get good grades so i really cant build anything rn :(.
That thing is an absolute beast. Very well done man.
Still kinda wish it performed better honestly! Loneoceans had a smaller coil with what should've been a weaker setup (half-bridge with 1875uF bus capacitors, a 0.15uF MMC, peak current at roughly 400A, and a 13" coil), and he got up to five-foot arcs, while I only ever hit a bit over four feet. I might tweak it eventually...the primary coil could probably be raised a bit and have another turn added. Maybe a larger topload and even more primary turns would help? Hard to really say why it's not as good without more testing!
@@LabCoatz_Science I know literally nothing of the solid state versions of this but I will say I was immensely surprised by the effects of swapping out secondaries. One was wound with scrap wire that was slightly finer than 36 AWG but not by much and was 1.5'' x 8'' .This gave me nice 1" sparks once tuned, with medium coupling good current output, had decent Q, and was a little finicky about tuning; so much as placing a large grounded object near managed to change the resonance drastically causing brush discharges to kinda dim out a little then pick back up once it got close enough to arc. The other secondary I never managed to film that one but it was from a failed bigger one. The aspect ratio of that one was really bad (beginners mistake) but it was varnished and conveniently 1.5" so I sawed off a 4" segment from it. This was wound with 38 AWG (this was a nightmare to wind as it's literally as fine as hair.) Q was noticably lower as the band width went up (less picky about the environment) and coupling was clearly higher as it had the same voltage but the arcs from this were not the same at all, they came in intense pulses that had a tendency to ablate anything they struck leaving pitting and often showing incandescent bits getting thrown from where it hit. Not much retuning was needed as they had roughly the same inductance but that just shows the difference between the two. Sorry about the long rant hopefully this was somewhat useful though.
It's great to see you find your voice and comfort on camera!
The Florida pool pump motor repair guy 32750 approved ! that was good info
Amazing as allways brother !! I like the fire trick , looks like some wizzard trick
Amazing!! That’s a pretty damn low resonant frequency too. Definitely would be nervous being shocked by that
I love the build. We seem to have similar looking coils lol. I have never tried touching my arcs but i forgot to hook up my earth rod connection one night and i got a pretty nasty shock through the metal case of my variac. Never going to forget that again
This is amazing! I've got some laser-based videos to finish up first but I'm actually planning to build a drsstc of my own soon!
It's beautiful man, definitely a show piece. The car idea is great lol, quick and easy way to get that perspective of oh crap they're coming right at me lol.
exactly what i subscribed for! Awsome!
That coil is a beast!
Video deserves way more views for the effort you put into it brother
Thanks man, I appreciate it! Tesla coils just aren't as popular as chemistry it seems, haha!
Such a fun (and scary!) piece of technology.
I’m fairly sure that you really p155£d off anyone listening to fm radio in a 5 mile radius
I'm guessing not. FM runs at such a high frequency that I don't think it matters. Like thousands of times higher.
An amazing display! Great presentation! I want to build this. Where can I go to buy all of the PCs, components, and schematics to make this beast? Thank you for sharing this scientific work of art!
ive been waiting for this
Nice man
propane balloon was an instant sub.
Amazing Tesla Coil,
Is there a place you can share the schematic, any additional information you have from building your first DRSSTC including more information on the GDTs connections/placement, and could you provide
information on the supplemental parts you and Allscience used in building LoneOceans UD2.7C, the parts list he has from Mouser has discontinued parts, as I would like to build it from scratch, or do as you did with Allscience if he allows.
Thanks again!
Sooooo awesome!!!!
Okay I think that's the most complex project you've dome on your channel
Holy &%@# that is awesome! Nice work...
.. So all you need to do is connect your base of the resonator to your transmission waveguide. And push Pull your primary into different modes of operation.
Over to an opposite wound receiver of identical tuning.
Electric fire 🤯
Absolutely fantastic! That is insane it only draws the power of a toaster. What power does your Spark Gap tesla coil draw?
Roughly the power of three microwave ovens (over 2-3kW most likely).
How did you handle the current draw? I am making a dual MOT tesla coil with some friends at school and when shorting one MOT we drew around 60 amps according to our ammeter. Do you think a ballast or a variac will be enough to allow it to run off of a 20 amp circuit? @@LabCoatz_Science
Is this at all close to the impact of an EMP or CME?
Would it be possible to simulate either of those events and test the "EMP proof" gadgets for vehicles etc. (Also: test DIY faraday cages to see if they'd hold up in a real event)
I see the faraday cage at 10:20. That is cool. However, i'm wondering if the trashcan 'cages' etc would actually in real world scenarios, to protect your phone and stuff when you know the sun might be spittin' out some nasties._
Honestly, EMP weapons usually utilize ultra-high magnetic fields instead of electric fields, but the concept it fairly similar. Even a thin layer of aluminum foil should be enough to keep out almost any sort of EMP!
try using a wire to disperse the electricity to other unit's , small light bulb's will be the preferable use , as with more output will require a larger unit
Whoa! How did I miss this???
UA-cam just hasn't been recommending my Tesla coil content very much recently!
@@LabCoatz_Science Excellent output too! What's your mmc rating?
@@KDewees91 it's a 6kV/0.25uF bank of 942C 2kV/0.15uF Cornell caps (five parallel bands of three in series for a total of fifteen capacitors). So far, it has handled pulse duties up to 200us and 200Hz with flying colors!
Excellent!
God help you if you ever need to use your home owner's insurance haha.
Have you tried using an scr to control the main power input?
Nah, don't really need to. The Variac does a good enough job, and if that weren't an option, turning the pulse times down on the interrupter naturally decreases the arc size.
Can't wait to see what new toys you get to play with in college
"Why worry? Each of us is carrying an unlicensed nuclear accelerator on his back."
I remember my salt water bottle capacitors and taking a fairly large discharge 😂 worse than a stun gun
Video idea: show what happens when you replace that copper rod that sticks out of your tesla coil with sparkler.
Amazing coil!!
Now all you have to do is make a MIDI interrupter and make your coil play DOOM.
2:48. I DO!
Zappy bread goes brr 🍞
So the only thing is Tesla designed his system to not radiate out in to space but to be connected by one wire or ground and realize the full energy at the receiver virtually.
hi might you car start to rust where the arc's hit it?
Nah, the paint protects the metal fairly well, and the arcs weren't hot enough to remove it.
Did your dad do a lot of projects with you when you were younger? I want my son to be as interested in STEM as you are.
We did some projects, although they were usually ones I came up with, lol! I would say the most important thing is to allow kids to try things and experiment. If your son has an idea for something he wants to build, see if you can make it possible! And if he's not currently interested in STEM, don't worry, it's definitely not for everyone. But there are lots of areas in STEM, and it's possible he simply hasn't found the right one for him. See what he's interested in and figure out if there's a way to mix science with it!
Make obscure fragrance molecules that are less known/ no one made before
Build an EMP next.
Anyone remember that top gear episode?
How much did it cost to build it?
In the end, roughly $500.
I would love to see you extract capsaicin from the world's hottest pepper pepper X
I just bought some of the Last Dab "Xperience" sauce, with 91% pepper X (nobody can buy the peppers themselves yet, otherwise I'd be growing some along with my Carolina Reapers and other peppers, lol). Not sure how much I'll actually be eating though, so it might be fun to try extracting the heat and purifying it!
I wonder if zapping a car is potentially dangerous to the electronics, I'm a mechanic and I've seen cars hit with big shocks and ruined completely, but I've never heard of a car hit by a tesla coil, I bet there is probably a specific amount of electricity where a car might start having stuff ruined, it probably also depends on where and how it gets hit and if exceeds the rating of everything or because it somehow zapped a computer dead. Mostly just curious because I figure you probably thought about the risk and determined it wasn't that bad before doing this
Styropyro special guest? 🤞🙏
Maybe whenever I finally film my 40W single-beam laser...
OK testing the electrical conductivity of fire was definitely different.
Nica and impressive build, but you were lucky not to fritz your car stereo or engine controle module with that thing....
MMmmmMmM tesla toast
Now make a VTTC
Petitio Principii
Damn
11:20
This is how Tesla wanted his cars to be charged.
Besides for scaring the s-ht out off cats and dogs, as well as wet party tricks ... what is the use? 🤣🤣🤣
Absolutely nothing!
@@LabCoatz_Science that just makes it even more fun to do if the practical use for it is absolutely nothing in my opinion , just like the practical use for throwing chunks of alkali metals like sodium and potassium in water and watching them explode violently is absolutely nothing but it's still so much fun to do it as long as appropriate safety measures and safety equipment like a full face shield are used. Is the electrical discharge from a Tesla coil a high voltage and high amperage electrical current and therefore capable of causing serious injuries or even death if someone gets too close or is it like a van de graaff generator which builds up a lot of high voltage static electricity but which has little to no current and therefore is capable of delivering a painful electric shock but one that is unlikely to cause injuries ? Glad you know what you are doing as well that looks like something that should be left to experienced people like you who know how to do it as safely as possible.
no tesla coil vs tesla car...i am disappoint. i have a g6 too
Can your DRSSTC Tesla coil power a microwave oven 😋
I wish I knew wtf was going on
