Thank me for watching ?.......no no no , More like thank you for sharing that awesome coil with us , that was freaking bad ass !!

Wow, thanks so much for the tour of your laboratory and demonstration of the different drivers. Love to see all the excellent making and doing. Not to mention the collecting of of all the terrific gear!

Those are two amazing drivers and your attention to detail is bar none. Really great performance. One new old technology I just learned existed is vacuum tube drivers.. Really cool with some arcs I've never seen/heard before. You own one?

I literally said it was a B.F.C as the camera approached it. I have no idea what else one could call it lol. Thank you for your content.

Very nice setup. I salute your efforts to try to understand and quantify the different drive methods. I originally (6 year ago) went for a DC resonant charging supply setup with an asynchronous rotory spark gap myself, and have achieved 130cm continuous discharges from a 12x47cm (winding diameter and length) secondary, with a 50nF primary cap, 130kHz Fres, using approximately 2300VA. I used 2 MOTs and a halfwave voltage doubler. I am now thinking abaout reviving the system and changing to a DRSSTC driver... :-)

Glad you like it. Still working on it. Today, just got done working through a problem with measuring secondary first-turn voltage. Will have much more about this project to come.

Did he just say "FULL BRIDGE RECTIFIER"

Eric.... Thanks A LOT for sharing this! I have been wondering if ever electronics will keep up with a real spark gap. You showed the truth! Awesome!

I can't wait to learn everything I can from you you seem like an incredible person to learn from and I am very eager to learn from you

0:12 Meanwhile, old guy in chair in the floor above is wondering why the TV show he is watching is getting so exciting.

That's a great piece of work, well explained. Great to see attempts at instrumentation which as you say is made very difficult by the high magnitude EM interference. Thanks for taking the time to upload and explain, and thumbs-down to those who disliked your video.

lucky to find that sync motor , nice solid build .

Great channel. I had no idea I'd go from watching you hook up an old volt meter with a single resistor to THIS.

nice work man!

my mind is blown..well done

Your build is insane!

Thanks for the informative video!

Loved the vid...and thanks... Just curious about the mouse balls... I'm familiar with these mice and the old mouse balls were a synthetic, (like hard grey rubber) The ones you have in the jar look just as I remember them...different shades of grey. Did just IBM use steel ones? PS I'm an old guy, have been playing with/building PC's since the 80's...Anyway, I liked to play with this stuff ages ago..Was fun! Used 2 811A transmitting triodes to power the tank circuit of my tesla coil, still recall the plates glowing red after a minute or so.. Wonderful memories!

I have no interest whatsoever in the topic, and i have no knowledge either of anything related to electronics and electricity etc, but i'd just like to say that this is an awesome video and this is what youtube is for! I'm sure SOMEONE would find this video highly informative and useful. It's just not me :P Keep on rockin on dude! EDIT: Love the conductor toy figure with his stick(or a wizard with his wand or whatever it is)

I enjoyed this video congratulations

congratulations!!

poor lamp XD nice coils and run good sir !! subbed..

22:46 rip headphones :D Nice, informative :)

The BOP allows energy to bleed out of the system at a steady rate. Without it, too much energy builds up in the primary circuit before the output discharge forms, and could damage the driver electronics. That is what I have read, but not experimentally verified for fear that I might damage it. I may investigate this claim after I finish my primary research, and damaging the circuit would not be less severe.

Nice set up and a LOT of work!. Have you tried lining up the electrodes, leaving the motor off, and running it as a passive gap coil? And most importantly --have you considered marketing your custom Nikola Tesla Breakout point?

nice looking coil. had to stop at12:30 to go to work.

I hope you finished your PhD project by now! Great Job! Any idea what your parts cost was on the H bridge setup not counting what was driving the H bridge. In other words ... just the circuit boards that were under the metal shield.

Well done

Most impressive creation I've ever seen on youtube, does the synchronous motor turn dc to ac , or does it mainly increase frequency?

Awesome !! Thumbs up :D Alex

Best Tesla Coil video ever!

Excellent! Brilliant! Awesome video!☺ tesla rules!

Further more, Quasi-Continuous-Wave DRSSTC's represent a further refinement in Tesla coiling over the last decade. They employ a synchonous buck converter to shape the voltage waveforms delivered to the transistor bridge, allowing accurate control of spark shape, length and energy dissipation: A few QCW-DRSSTC's I've seen also employ a microprocessor to allow full real time adjustment of the input power and waveform during operation.

Hi Eric, Nice job! Congrats 100% Dont you think that Nicola Tesla decoded opposit effect of Coil for power trasmitting? To make it work opposit way thats the goal!

(Mouse balls.... lol!) Great setup and awesome video! Thanks!

Hi mate' Great video' enjoyed ya example to compare the both coils, im more of a fan of mr teslas designs the analog one, I love them coils, you havnt much to go wrong and you can run them for thousands of hours with no thinking somethings going to get too hot and burn out lol, You can definitely see the difference between the 2' when you watch the video over a couple of times" and I do love to see the streamers from the rotary tesla. Thanks again for sharing your video mate' and if ya get time have a look at mine running in my garden @ around 3000 watts Thanks ☆☆☆☆☆THUMBS UP☆☆☆☆☆ high1voltage1rules

Awesome video very detailed well you settled the debate I had with myself I thought the drsstc would output better but not much difference the sgtc is cheaper and easier to build so I'll be going that way thank you for the video again very good job going through everything I know it's older but again thank you oh have you ever tried bifiller primary? Due to the capacitance it creates I'm curious about the effect it would have on the circuit

The spark gap streamers seem to have a bit more meat to them then the solid state driver. Great video though, you got a like from me :) You should do a comparison between the two drivers and a vacuum tube driver on the same coil. Use an electronic grid driver so you don't have to use a feedback coil.

What SPL weighting factor were you using on the dB SPL meter? A, B, or C?

What are the values for the full bridge rectfier?

dUDE YOU ARE GOING TO MAKE IT!! dpdtBI POLAR TC 620KHZ +--

Hello Erik, what did you coat the mouse balls with to get them to have a conductive surface?

how about the ozone generated by the teslas, are you airing the room or how do you go about with the issue of the ozone generation?

would changing the speed or the rotary spark gap change the frequency?

I wonder if the sstc was more twisted and turned because it was weaker and needed to find warm air pockets with less resistance to travel where as the sgtc just bulldozed through the air regardless of temperature? But then again you did say sstc used less power.

I just finished a dc flyback version. Gets bout 250kv but i want 4 ft arcs one day.

Is there a schematic for the DRSSTC?

What capacitor do use in your bank... where can i find them?

I got a nice reading for you: Eric Dollard - Condensed into Tesla Transformers.

I have a few questions. What would happen to you if you touched that 'stream' of electricity coming out the top? If there was no roof there, would the electricity still go straight up in the air since i remember you saying it likes to go straight up and you did something with the roof too, and if it will go straight up, is there any way to weaponize such a device(Ie i wanna be able to do FORCE LIGHTNING!) So basically is the roof 'conducting' anything or is it an insulator? Where is all that electricity going in the end? Or does it just 'disappear' in the air?

Why do most DRSSTCs use a breakout point? One of the things I love about my SGTC is the streamer dance. Can you get a decent output without a breakout point?

How much hertz has had the original Tesla Coil?

With this setup... Are there enough fuses in your house?

Did you change your channel name?

Wonder what your secondary output voltage was,.....maybe 500,000 V?

Yeah Penn State!,

Can you give me part list and diagram

This man has a collection of mouse *balls*

Can I buy your stuff? I am fascinated with Tesla coil but not succesful making one. Please I want to buy it!

Actually the IGBT bridge, along with its controlling circuitry, is far more advanced than anything Tesla ever built. A modern DRSSTC has more in common with a high power radio amplifier, or high frequency induction heater than it does with the traditional "Tesla coil" design. Transistor bridges are a modern circuit topography that do a whole lot more drive a Tesla coil: They are present everywhere, from switch-mode power supplies and audio equipment through to multi-MW motor controllers.

tribute to Mr Nikola Tesla. We owe him everything!

Most of my smaller DRSSTC's don't use a breakout.

Okay I'm at 18 minutes and 44 seconds India video and I'm noticing that I did the same thing a little while ago maybe a year-and-a-half ago but I Had A Little More Voltage I was using just under a 1 million volts, I ended up destroying three of my LED shop lights. And the other thing that happened was ended up leaving lines of conductive paths in my ceiling which kind of destroyed it but it sure looks cool

Oh! very good! tesla impact !!!

Dont set the roof on fire!

Love this video! I've made very small ones with a 5kv primary. Question though... with the cool little Tesla point on the top - is the torrid even necessary? Maybe for capacitance? I had a neighbor who has a bigger coil than this - better than museum quality. Also has a spike on top (a nail). The story was - my gf told me my computer was talking while I was out. Silly girl - that's impossible. My computer is off. This happened a few times. No, no all women are crazy. Until once, when I was home, she said 'you're computer is talking again.' There there silly girl... but i walked out to our computer room. Sure enough it WAS talking but very faintly. :O I plugged a headset into my computer and I could hear what it was saying. Sounded like a nice man with a radio voice who ended with a radio call sign. Via google, I hunted him down. He lived on the other side of my block and a few houses down. I took a walk and went to his house. His wife answered the door. I explained I come in peace but I was just wondering why I can hear her husband over my puter speakers. Initially, they took it as a complaint or didn't know what to make of me, but seemed willing to accomidate. I explained that I was only curious; he wasn't bothering me - just wanted to figure out the mystery. I told him I thought my gf was crazy story which is pretty funny. He was a ham radio guy with a 100 watt TX. I reassured him it was no bother, and that I was in to electronics as well but more digital 5 volt stuff. He took me on a tour of his radio room cause I was genuinely interested. Showed me his receivers and transmitters etc, showed me a working old TV in a plexi box, and a radio - all analog tubes. Coolest evening I've had in awhile - wasn't expecting that at all. I was telling him I really don't know much about vacuum tubes or analog electronics... I tried to make a Tesla once and it nearly killed me but great stuff. He ran out of things to show me - long conversation was winding down. I had made it clear I had not come over to complain and was about to leave. As I was about to say 'okay thanks - I just wanted to solve the mystery.' He said why don't you come into the garage... I've got a bit more radio equipment in here. So the two rooms connected, and I followed him. It was dark until he turned on the lights. When they came on I was standing right in front of the biggest Tesla coil I've ever seen in real life... Even at science museums (which I've seen pretty big ones). I was almost in shock - did NOT expect that at all. A well built machine too. He had a friend he loaned money to who couldn't pay it back. This neighbor guy told his friend - instead of paying me back, help me make a really good Tesla coil (cause he was one of the best makers in the world and I have no idea who that was). Of course he fired it up. Was not using either driver you tested. Was (I think) a 20+ stage spark gap. Not sure what frequency it hit at, but by the sound you could tell it was very constant. Sorry, I can't tell a short story... but it also had a nail on top of the torrid. Is that necessary? :P

Please use a tripod for your next video. It is very difficult to follow with the picture and focus swaying around every which way! Excellent job, on your build sir!

Wow that is a bfc

solid state all the way....

not sure why I watched that whole thing

My headphones lollll

Weston meter stolen from Doc Browns Amplifier .... I will call Marty !

The switch is at the most worst place ever... you can accidently shock yourself from touching the primary side.

My friend, please be careful with your experiments, you know that a little mistake is the difference between the life and death...! i like your videos but i don´t like high voltage...!

cen a smal tesla coil be dedly

Most likely an Edison fanboy ;D

Okay at this point are you just showing off or what
