Hey Everyone,
I hope you all enjoy this video as much as I enjoyed building and designing the thing itself! There will be a few more videos coming out about this tesla coil because I felt like making multiple videos that illustrate the build process rather than one that just shows off the end result. I've always been very entertained by build processes. Also, I know this is not a very educational video, but that is because I want to leave the teaching to the experts listed below. They have made very in-depth videos on this topic, so I highly suggest checking out their videos as well if you are interested in high voltage! Please feel free to leave any questions you have about the MOTs or the MMC in the comments below. Stay tuned for more videos about the primary coil, secondary coil, and lots of high voltage tests!

Glad I could help on your journey into the high voltage realm! I'm sure part two will be a big hit. Thanks for the recognition at the end there, I'll take second place to "Mom and Dad" any time, lol!

Not bad! If I was you and had only 5 MOTs, I'd use 4 in series and 1 for ballast though. The orientation of spark gap is questionable. I'd oriente them upwards so that the hot plasma from the spark gap rises upwards and quenches plasma. You should also install fan to quench better because otherwise, it will only run for few seconds.

i considered using that MOT configuration too, but I saw styropyro had to put the transformers in oil to prevent secondary-self-arcing that occurs at that voltage, and i didn't want to deal with oil or replacing the transformers. and i actually do have a fan installed!

Hi ! Really cool video, I've just seen part two but I still have one question about your MMC. I guess you used the formula C = I rated/(2π * V rated * frequency) But how did you measure I rated ? It must be different than what's written on the MOT because you are using a ballast ( but the thing is I don't quite get how inductive ballast works yet). Any welp would be appreciated 👍
@BackMacSci
@BackMacSci 2 года назад
Hi Thomas! I'm glad you liked the video! You can buy a device called an ammeter to measure the current being drawn by the tesla coil. Most of what you need to know about an inductive ballast for tesla coils is in this video. I hope that helps! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-zo1TYNwWjJo.html

I have seen diagrams online that use some sort choke on the HV side to protect from back emf (?). I was wondering if you considered this and what your thought process was behind including/excluding it. Thanks

Hey man, great work! When you wired the MOTs in series, did you disconnect the secondaries from the iron cores? I have 3 MOTs I'm trying to stack but I've already ruined several by trying to isolate the cores
@theVHSvlog
@theVHSvlog 10 месяцев назад
Re-watched the video closely and looks like you kept the secondaries connected to the core. I'll do the same!

is the EMI filter wired to the input power ??? what size bleeder resistor did you used ??? I'm looking for capacitors , the 15k capacitors you used , seem to be unavailable. any suggested replacement ??? do you have a good source for capacitors ??? Thanks.
@BackMacSci
@BackMacSci 10 месяцев назад
EMI is wired in series with the input power, i used 1Megaohm, 1W bleeder resistors, you can use these capacitors but you’ll need to wire them together differently to make a 45 nF MMC : www.aliexpress.us/item/3256802731782973.html?srcSns=sns_Copy&spreadType=socialShare&bizType=ProductDetail&social_params=20802194008&aff_fcid=1acb08e301d9492f91719e4dbb6af610-1674627601628-05913-_mNKGFnC&tt=MG&aff_fsk=_mNKGFnC&aff_platform=default&sk=_mNKGFnC&aff_trace_key=1acb08e301d9492f91719e4dbb6af610-1674627601628-05913-_mNKGFnC&shareId=20802194008&businessType=ProductDetail&platform=AE&terminal_id=121a42d3352340728d01413f64ecb578&afSmartRedirect=y&gatewayAdapt=glo2usa4itemAdapt&_randl_shipto=US

What does the bleeder resistor do?
@BackMacSci
@BackMacSci 2 года назад
it converts the dangerous charge stored in the capacitors into heat once the tesla coil is turned off. without the bleeder caps, the capacitor bank could give you a nasty or lethal shock if you touched it after turning the tesla coil off. thanks for the question!

200,000V $200 capacitor bank? I thought 3 times the transformer voltage was good, in your case 20,000V is plenty. 2700nF? I thought 50 was good.
