@thomasgodwin3184 i actually have no exact answer to this when im honest🤔 Im using wastewater tubes, the are called here in germany "HT Rohr" and the material is polypropylen. I read many times that PVC tubes just work fine too.. When you work with extremely high frequencys, or Just have the materials laying around, cardboard tubing, glass or ceramic are really good i heard.
@ I think I’ll do the polypropylene pipe for now until I find some glass or ceramic for the primary coil does it matter how far away it is from the secondary?
@@thomasgodwin3184 the primary pipe Material is not that important. It is more important on the secondary (the long one). Yes the distance and height of the primary to the secondary is one of the most important things! This is known of "coupling". Especially At VTTC's (especially low power VTTC's) you have to try to get a really high coupling, that means you want to have the primary as close as you can to the secondary, and really high. But with a strong coupled primary, there is also a really high risk for arcing betwen the coils. So in reality you want to find the ideal Spot, where you not have any arcing but also have the highest coupling you can acchieve.
Cool demo. Thanks. Would be interesting to see some air pressure, temperature and humidity tests and readings. Seems like it's hard to replicate many HV effects properly, cause it's so sensitive to the air.
@@Kangsteri thanks too🙂 Unfortunately i have nothing to measure the exact humidity and pressure of the air... but yeah probably in the future😁 I found out, that in the last 2 days, it was very foggy outside.. In that time, the coil was running a bit better.. Also the arcs got straighter with the double electrode. So i think today the air is more dry, and my secondary coil has a bit higher frequency because of less loaddown. When i add the long double electrode, maybe i load the secondary a bit more.
@@bassmaster9781 thanks🙂 No not at this coil. But this would not work properly, because of the very low coupling to the secondary coil. Vacuum Tube Tesla Coils need a really strong coupling betwen primary and secondary for maximum energy transfer🙂
Awesome build - very cool, you must be on or approaching a max output - 👌 I wonder if also humidity plays a part in your different out put characteristics 🧐
@@Jonodrew1286 thanks mate🙂 Yes im now absolutely aiming on the biggest output possible in this "small" application. The humidity/temperature/pressure of the air plays actually a role into that! Because this changes actively the load on the secondary coil. Now in this video, the air is more dry than the days before. In that case, the topload and arcs do load down the secondary less, than before.. so i have to retune the primary circuit just a littlebit to a higher resonance frequency.. A good indicator for that was also that the coil was running just smoother with the double breakout, because the two big arcs plus longer electrode load the secondary down a bit more (Just my theory in my head, but makes just sense to me)
@Jonodrew1286 i drive the MOT's also on the primary in series with 2 phases 400v So im capable to push 8kw. But i dont know, what the MOT's actually draw... maybe 3-4kw🤷♂️ didnt measured it
An interesting thing to try would be burning a red road flare outside upwind of it, so that the arcs travel through the smoke and maybe change color along their whole length. I'm not sure if that's possible, though, since you'd have to assemble and operate the coil outside. A very fine saltwater mist (like from a humidifier or something) might work inside, except that has a risk of contaminating the electronics.
@@odincauzza2509 haha crazy cool idea with the flare!😃 Unfortunately its not possible for me here in the city🙄 That saltwater would be too hard on my copper/aluminium parts, sorry😬
@@edgarw5919 no, the weight depends of how much Material is needed, or Just used. And that depends on what your tubes impedance, power supply impedance, resonance frequency, primary diameter, cablediameter and avaiable primary capacitors are🙂
@@benjaminlockhart99 thanks🙂 Yes, i was trying different DIY toploads, but they didnt work that great. Now the topload is 40×160mm I think a slightly bigger and well made topload like 50×200mm should be good.
@egg99 es kommt auf die beschaltung an. SSTC's gibt es sehr viele unterschiedliche. Ich glaube dass tesla spule die mit "mains ramping" arbeiten, sind die leisesten, weil sich die entladung bzw. Der Blitz langsam mit der ansteigenden sinushalbwelle der spannungsversorgung bildet und größer wird, und nicht plötzlich mit voller Power entsteht.
😮, a Faraday cage would possibly protect your electronics (copper mesh) I would be interested in the effect of a Chladni Plate (pattern) configuration through your output (modulated) possibly with salt instead of sand etc... ❄️🔉
@@redloki_53 yes, i think it is getting time for a faraday cage😅 but this is not that easy in my room. I have actually no big problems with electronics. Only with my Smartphone, when i'm really close. Also the W-LAN data rate is a bit less while running the coil. With my SGTC i had actually really worse problems, but not with my VTTC. Interesting idea with the modulated pattern! Unfortunately i would have to make quite some changes, to do some (really good) audio modulations with that coil. i want to do that too and it got requested a lot😀 I need some time for that (and money) to build one. But i will make that in the future🙂
@ effects of some of this specific patterns would have possible astounding properties . Interesting also would be the effect of a fast rotating (output) Antenna.🙂 🤞🏼
@@redloki_53 yes, i want to try a ion rotor too, but everytime it dont want to turn because its too heavy, or it is just melting in seconds because its too thin wire😅
eion Tip.wir wissen von Ionenantrieben das plasma sich bevorzugt zu magneten hingezogen fühlt.heisst,wenn du über dem ding am alu ein kleines magnet anbringst wird das plasma das magnetfeld finden und du kannst es glaub noch höher hängen.
@ oder mal einen lautsprecher an die decke nach unten gerichtet.sound sind ja auch magnetische wellen,die dann nach unten gesendet werden und das dürfte doch auch wie eine treppe für das plasma sein.zumal ja musik unterschiedliche frequnezen hat tanzt vielleicht das plasma nach der musik die von oben kommt. wenn di durch die alufolie oeben eine kleine spannung fliessen lässt,also zwischen plus mit batterie und glühbirne wird das Alu noch attraktiver fürs plasma weil ein Strom fliesst.
oder ganz krass,du baust dir einen helmholtzcoil und montierst den horizontal um deinen teslakopf so,das der blitz genau da ist wo in einem helmholtzcoil halt die mitte ist. mit helmholtzcoils kann man ja etwas an einem punkt berührungslos fixieren. also mal den Plasmaüberschlag in einem etwas grösse geratenen helmholtzcoil fixieren.
Это уже даже страшно, были бы интересны замеры потребляемой мощности (или вывести отдельный амперметр, и параллельно с образованием дуги, попадать краем кадра на амперметр.)
This setup is more comfortable than the other. Congratulations.
Sometimes the arc hitting the target tin foil... Impressive and funny experiment. :)!

Good job man, I’m just getting into this and learning about it and building one, your channel is helping me understand thanks keep it up

What always interest's me is, should the weight of the copper in primary and secondary coils be the same?

Tig welding wolfram sticks, rhodium coded for spark discharge point . let the discharge spark turn at the top.
@@edgarw5919 i actually have some tungsten TIG welding sticks! But not rhodium coated... but I will try it anyway😁
Great work, I suggest trying a larger topload to reduce the effects of arcs pulling the secondary out of tune.

Yes, i was trying different DIY toploads, but they didnt work that great. Now the topload is 40×160mm

Ozone? Can i also suggest a fire blanket and fire extinguisher.....just to n case.
@@clintmichigan9112 had all my Windows open to get rid of all that ozone and other byproducts of the arcs
Increase the ground cable gauge to the input of your secondary output will be bigger.
@@edgarw5919 actually not🙂 everything is gronded properly already.
👍 wie laut ist es?

for me its only possible to measure the current draw from the MOT's.
Yeah an analog amperemeter would be awesome!
