@@Zenodilodon It is an honor to hear from you as well! Please keep up the great work! Perhaps with some stacks of sot23 fets etc., you could make a high-power micro ZVS driver, just as an idea. Thanks again!
I don't recommend putting mosfets in parallel, this can mess with things and I have has situations where instead of starting the osculation it turns on on both sides a bit more and cooks mosfets. I would just step up to using a larger mosfet instead for this application.
If this goes well the next one will be equally in depth on making burning lasers out of ANY laser diode form factor. Elias thank you for the input, it's a new thing to try and extremely rough but let's see how everyone responds :P
Zenodilodon This is seriously awesome, I love experimenting with electronics, and you guys just do exactly what I think is cool. Lasers, HV, DIY gadgets, miniaturized tech, etc. It's just perfect and you guys are soooooo underrated.
I watched all the video and you explain everything, but I don't understand how did you connect the zvs driver to the tesla primary and secondary (the tesla pen)
Same as any transformer in the video. You have a primary with 3 legs on for each mosfet out and then the center tap for ground. For use like a plasma pen any high voltage ZVS will do the same thing if you ground yourself placing the " closest wire to primary " of your secondary coil to yourself acting as a ground and then placing a sharp tip on the furthest secondary output. Please also not the pen is NOT a tesla coil, it uses a rewound CCFL inverter transformer. It's just a high voltage transformer and ZVS crammed into a little tube.
Running tesla coils of ZVS can get tricky as they often don't have much magnetic if any for proper ringing on a ZVS, other options like spark gap or other transistor set ups will be better for running an open air core transformer like a traditional tesla coil, The ZVS works great for magnetic transformers.
Did you figure out the differences and find a working solution for a tesla coil? You can also try to play with magnetic transformers more on ZVS. There are Tesla coils that use ZVS + high voltage transformer to charge a capacitor bank for a decent sized spark gap tesla coil. Also did you find the other video I spoke of on Join The Technicians?
Zenodilodon I see the video of the plasma pen one year ago I put a comment on it, it is awesome tutorial but I wanna make the tesla magic marker and after the plasma pen
It's coming, it's a simple n2222 slayer, not much special really. I want to try to make a better set up before I tackle it because I would love to see a little more power out of it, aside from that it's as it is now not much special. Video work is not my forte, it's slow and a side task for me but as I said, it's all coming and more.
Plasma pen was nice work. And I myself wanted to create one, so I made ZVS circuit as shown in your video of plasma pen then I tested it using LEDs as shown in this video , it worked fine but when I connected it to transform then there was literally no output voltage not even small voltage, I think my transformer was also fine as when I connected it with 9V battery then at time of conncting it to battery current jump up and goes down on disconnecting so it had shown a small voltage output just with battery, so transformer was fine. But I think switching was not occuring when I connect ZVS to transformer or may be another problem. Can you tell me a way to fix this issue?
Your inductor is probably the cause. There have been situations where I have tried inductors at random and it makes the circuit not work at all. It's about the only thing I can think of that would prevent it from working correctly. Also what voltage are you using for input and what resistors are you using for the gate pull ups?
@@maniksingh4119 Your resistors should be good. I cannot simply tell you what inductor to use as that all depends on your transformer and configuration. Pairing a transformer and inductor is one of the harder things to do and it can be a bit of trial by fire.
Sir, I had tested circuit with 5-6 inductors but none had produced output, are you sure that it is problem of inductor and you had mentioned inductor in description maybe 4r0 inductor something what does that mean? Please guide me
Tak naprawdę nigdy nie było schematu pióra plazmowego, ponieważ był to projekt darmowej budowy. Mój przyjaciel też je zrobił i razem zamieściliśmy tutaj, jak zrobić wideo. ua-cam.com/video/My_J3xzDaZ0/v-deo.html
At 51 minutes you say "they're gonna be going in opposite ways" but they look like they're a constant direction of rotation, with the centre tap being just being an interruption, in a continuously spiral helix. Am I misinterpreting what you say, or am I misinterpreting what I am looking at? Thanks. This is the best video I have found on explaining the working of a ZVS. The smoke tests really do help clarify things. Great job.
I say that they will be going in opposite ways because I started at the center tapped point. From either side the coils will go the same direction when winding. I hope that clarifies things up. Glad you found the video useful, I wish you the best of luck on your projects!
watched your video! very informative! could you point me to where i could calculate this stuff, or at least what things i should try to search. thanks!
That's the largest problem for ZVS stuff for most people is the calculations. It's not exactly straight forward. It's similar to an LC oscillator circuit in that you have inductance and capacitance in the equation however due to there being 2 magnetic components the inductor and transformer it becomes much more tricky to get the optimal balance. This is why I went through so many different set ups and included both success and failures to show physical correlation and effects of changing parts out. You can try to use JavaTC to do your LC maths quite a bit but it's still a tricky task. Even after a few years of messing around with this stuff it still can be hit or miss with how well something works. I do have planned for 2021 an update on some things I have learned since this video so check back for that every once and a while.
@@Zenodilodon Thanks man! I sure will! I am also planning on laying with this stuff. I know how oscillating circuits work, so i think i will just have to do some good old-fashioned research on this.
Thank you thank you thank you. I am a tinker and a lover of Tesla, you are the best that I have found. Thank you thank . I have accidentally found a circuit. I’d love to share with you.
Can you do a deep dive into the plasma candle circuit ? I can’t find anything close to adequate regarding this topic .? Fantastic work on this one by the way 🙏
The trick with make a plasma candle is that it must be very fast, into the Ghz range and quite powerful. These are often done with large vacuum tubes and isn't something I have any experience with. Tested2Destruction might be able to help.
Very useful video thanks for that. Could you make another video explaining how to build that full bridge configuration transformer driver with coupling cap that u showed on video??
A video on full bridge circuits is in the future, that particular board that I used in the video is a prototype though and has some minor issues. It's based off the SG3525 IC which is analogous to the TL494 and is a dual output IC. We used a totem to drive the P channel mosfets. The issue with the current configuration is in the phasing between the 2 sides and thus the mosfets get hot since there it not a solid off during the 0 crossing.
hello I love your guys videos and got inspired to make something like the plasma pen from your videos. I have all the parts but am having issues with it. a couple days ago I got the circuit running nice and it was throwing about 1 inch arcs running about 2.4amps@9.6v off a homemade zvs but the circuit suddenly stopped working while it was running and started drawing alot more amps and the arcs were gone. long story short I changed every single part on the circuit including 3 different sets of mosfets. and still same thing except I realized that there was actually output on the secondary but I had to short circuit it to get an arc and could only draw the arc out like a mm. while still pulling 3 amps from my batteries. and when I tried making a different inductor with a screwdriver the current dropped to around only 2 amps but still the same size arcs. do you know why this is happening? thank you
Glad to hear you enjoy the content. It sounds like your secondary has failed in an area and this is causing the draw of current and lack of output power. It sounds exactly what happens when we had breakdowns in our secondaries. A good way to manage this is to write the resistance of the secondary down. If that drops lower then you know it's done. There is also another way of doing ZVS which has a center tapped inductor, or 2 inductors of equal size attached to how the transformer is attached in this video. Than you just put a 2 wire primary transformer on the 2 outer taps of the inductor/s It works amazingly well. If you e-mail me I can send you pictures of how this is put together.
@@JotticunChapter2 I watch the messed up subtitles, they are funny sometimes. I have seen them also omit strange stuff, like " None sense " was removed. I was like but why? 16 times smaller? That's like the size of a piece of rice.
Hi... just a quick question..... when connecting the zvs driver to a coil, is it OK to keep the LEDs connected as a visual indicator of status??? Awesome channel BTW
Yes you can keep the LEDs connected, keep in mind that when the transformer is connected that you may have to handle both higher input voltages and ring up on the transformer's primary so I would advise using suitable resistors in series with the LEDs and consider using 3-5 volt zener diodes to protect them. Thanks for the complement and good luck on building your ZVS!

@@Zenodilodon hehe, good stuff mate. Make sure you keep sharing your experiences. I keep zapping myself with capacitors still holding charge, so I'm steering clear of high amp designs for the time being. I figure at least a12 month period of no shocks before I step up the game. Lol. Cheers.
You say the negative voltage flows from the source to the drain... does the mosfet not show a flow from drain to source/ground for a low side npn? I've stopped watching until this is clear to me. I'm thrown off by saying a negative voltage flowing reverse through the source and through the zener.... maybe if you said electrons I wouldn't be so confused right now... what am I missing? (Btw I would have been stoked if you cut the whole face interview and just discussed all that with a bench view... only preference though since I watch so many videos like this.)
In real physics yes electrons flow from the negative to the positive, this is how I speak because it's applicable to other fields of understanding and models. The electrons in this circuit flow from negative into the source through the junction and exit the drain. Zener diodes are only used for gate protection and do NOT conduct until they reach threshold voltage. I also try to speak of negative and ground in context as if they are applied in floating or grounded systems. Ground is not the same as negative. Refusing to watch the rest of an explanation video without an explanation, isn't that like holding yourself hostage for money kind of thinking?
@@Zenodilodon I get your analogy but everyone's situation is different right?. I'm 31 with a new hobby I've invested copious amounts of my savings into and you creators are my professors. If I misunderstand something in a video this long then I can't take in the proper remaining info. My kid just turned 4 years old. so since I first picked up a dmm when she was 2ish I've been limited to night time lab and study time. Since my career is unrelated, I try and use those nights as efficient as possible. That's why I held off watching at the moment... (I meant to delete this so I commented on my active channel I use for electronics.. feel free to delete this stuff and I'll do my response question to your other answer since I feel I asked my question a little more clear there. I'll give you a follow on both channels)
I will try to help out with answers, I am unsure how to format information at times my brain works very well with real time physics but trying to make a format style presentation or answer is nearly impossible for my head lol. In that sense I suck up information like collecting puzzle pieces hoping to eventually put them where they belong. This video is kind of like an attempt to dump out all the puzzle pieces on the topic I have collected. I myself just started getting into this power electronics stuff about 4 years ago in a more serious manor and it's still confuses me to a degree as well. I am by trade an optical/laser tech and have gone into this kind of stuff as hobby as well. Is your other channel Steering Electricity?
@@Zenodilodon Yes. Starting a channel with my couple hours a night is hard. My kids finally about the age where I can get a little free day time sometimes so I just went and bought a nice multi camera setup and editing laptop so I can start posting with some consistancy and less filming struggle.

Any schottky or signal diode with the appropriate voltage rating will work. This is not a very important thing to consider and doesn't have to be exact, most diodes will work.
@@Zenodilodon so please let me ask more. I use mosfet p75n02 smd. input port G = R470ohm. and use zener diode 4.5 or 4.6 vol. is the 5v input port working properly? thank you so much
@@duongbui9621 There is significant ring up on these circuits, figure it can go up 4x when made properly. I typically use ZDs that are 15-19v as many mosfets have a gate voltage of 25v. This cuts down how much current ends up being dumped in the ZD and helps to maintain oscillation. I'd say using a 4.6v ZD is too low for this application.
@@Zenodilodon i want to make a pulse welding machine from zvs circuit. so, I have to use DZs 15-19v, right? and how much voltage the mosfet port will work. Sorry for not having enough knowledge in this field. Could you please help me
@@duongbui9621 Your ZDs must be chosen to closely match the gate voltage of your mosfets. Check on the data sheet for the mosfets you bought for the gate voltage and choose a ZD that is about -3 volts from that rating and you should be fine. If you are intending to use a higher voltage select a ZD that has a decent wattage rating for larger applications.

I'm just saying NASA's MK3 Drive is a 500-pound slab of shit that's 17 x heavier than 3 MK1 drives that would have been just as effective and had the same amount of thrust if they had just used 3 MK1 drive so why spend like 7 to 18 years and probably a couple of million dollars on something that's less effective what the fuck

I hope that helps you grasp a bit more what your options are, how they work together, and how to select/make your needed inductors for this and future projects.
@@Zenodilodon thank you very much, i will look into it :P
Hi, I saw you in join the technicians a few years ago. Glad I stumbled onto your channel. I have a love hate relationship with these zvs drivers lol.
Good to hear! Me too the ZVS is a simple but also tricky circuit. Too bad Join The Technicians kind of died :/ at least I am still going!
I love zvs circuits and arcs ,,, you are hero bro ....great work ....I will try it
i hope this helps you in your designs! Thank you for you comment :) Best of luck.
Thanks man I finally was able to make a zvs driver that doesn't blow up! Much THANKS!
Let the high voltage madness flow!
Thank you for the wonderful video! I especially liked the smallest ZVS supply that you made!
Ethan!, excellent seeing you here. Thanks for the comment, it's an honor to see you've enjoyed it.
@@Zenodilodon It is an honor to hear from you as well! Please keep up the great work!
Perhaps with some stacks of sot23 fets etc., you could make a high-power micro ZVS driver, just as an idea.
Thanks again!
when paralleling mosfets, do you have any advice other than an extra resistor on the gate ? : )
I don't recommend putting mosfets in parallel, this can mess with things and I have has situations where instead of starting the osculation it turns on on both sides a bit more and cooks mosfets. I would just step up to using a larger mosfet instead for this application.
Thank you so much for this video, of course I haven't watched it yet, but I will as soon as I have time to. Looking forward to it!
If this goes well the next one will be equally in depth on making burning lasers out of ANY laser diode form factor. Elias thank you for the input, it's a new thing to try and extremely rough but let's see how everyone responds :P
Zenodilodon This is seriously awesome, I love experimenting with electronics, and you guys just do exactly what I think is cool. Lasers, HV, DIY gadgets, miniaturized tech, etc. It's just perfect and you guys are soooooo underrated.
Prepare to see the smallest ZVS EVER!
If it's not small enough, demand smaller! lol
I watched all the video and you explain everything, but I don't understand how did you connect the zvs driver to the tesla primary and secondary (the tesla pen)
Same as any transformer in the video. You have a primary with 3 legs on for each mosfet out and then the center tap for ground. For use like a plasma pen any high voltage ZVS will do the same thing if you ground yourself placing the " closest wire to primary " of your secondary coil to yourself acting as a ground and then placing a sharp tip on the furthest secondary output. Please also not the pen is NOT a tesla coil, it uses a rewound CCFL inverter transformer. It's just a high voltage transformer and ZVS crammed into a little tube.
Running tesla coils of ZVS can get tricky as they often don't have much magnetic if any for proper ringing on a ZVS, other options like spark gap or other transistor set ups will be better for running an open air core transformer like a traditional tesla coil, The ZVS works great for magnetic transformers.
Did you figure out the differences and find a working solution for a tesla coil? You can also try to play with magnetic transformers more on ZVS. There are Tesla coils that use ZVS + high voltage transformer to charge a capacitor bank for a decent sized spark gap tesla coil.
Also did you find the other video I spoke of on Join The Technicians?
Zenodilodon I see the video of the plasma pen one year ago I put a comment on it, it is awesome tutorial but I wanna make the tesla magic marker and after the plasma pen
It's coming, it's a simple n2222 slayer, not much special really. I want to try to make a better set up before I tackle it because I would love to see a little more power out of it, aside from that it's as it is now not much special.
Video work is not my forte, it's slow and a side task for me but as I said, it's all coming and more.
your awesome . love seeing you work your brain seems to go like mine wen it comes too electronics . everywhere all at once .
Tank you buddy! I got my first zvs thanks to you. I improved the circuit a bit so i could use it as a induction heater. Im a big sub!
Glad you got your ZVS working! Thanks for the sub :P
Plasma pen was nice work. And I myself wanted to create one, so I made ZVS circuit as shown in your video of plasma pen then I tested it using LEDs as shown in this video , it worked fine but when I connected it to transform then there was literally no output voltage not even small voltage, I think my transformer was also fine as when I connected it with 9V battery then at time of conncting it to battery current jump up and goes down on disconnecting so it had shown a small voltage output just with battery, so transformer was fine. But I think switching was not occuring when I connect ZVS to transformer or may be another problem. Can you tell me a way to fix this issue?
Your inductor is probably the cause. There have been situations where I have tried inductors at random and it makes the circuit not work at all. It's about the only thing I can think of that would prevent it from working correctly. Also what voltage are you using for input and what resistors are you using for the gate pull ups?
I am using 333 ohm resistors and 5-9V for input.
Which inductor I should use?
@@maniksingh4119 Your resistors should be good. I cannot simply tell you what inductor to use as that all depends on your transformer and configuration. Pairing a transformer and inductor is one of the harder things to do and it can be a bit of trial by fire.
Sir, I had tested circuit with 5-6 inductors but none had produced output, are you sure that it is problem of inductor and you had mentioned inductor in description maybe 4r0 inductor something what does that mean? Please guide me
Great video thank you, now I know how to tune my zvs circuit!
do you have a link to that earlier plasma pen schematic?
Tak naprawdę nigdy nie było schematu pióra plazmowego, ponieważ był to projekt darmowej budowy. Mój przyjaciel też je zrobił i razem zamieściliśmy tutaj, jak zrobić wideo.
ua-cam.com/video/My_J3xzDaZ0/v-deo.html
At 51 minutes you say "they're gonna be going in opposite ways" but they look like they're a constant direction of rotation, with the centre tap being just being an interruption, in a continuously spiral helix. Am I misinterpreting what you say, or am I misinterpreting what I am looking at? Thanks. This is the best video I have found on explaining the working of a ZVS. The smoke tests really do help clarify things. Great job.
I say that they will be going in opposite ways because I started at the center tapped point. From either side the coils will go the same direction when winding. I hope that clarifies things up. Glad you found the video useful, I wish you the best of luck on your projects!
watched your video! very informative! could you point me to where i could calculate this stuff, or at least what things i should try to search. thanks!
That's the largest problem for ZVS stuff for most people is the calculations. It's not exactly straight forward. It's similar to an LC oscillator circuit in that you have inductance and capacitance in the equation however due to there being 2 magnetic components the inductor and transformer it becomes much more tricky to get the optimal balance. This is why I went through so many different set ups and included both success and failures to show physical correlation and effects of changing parts out. You can try to use JavaTC to do your LC maths quite a bit but it's still a tricky task. Even after a few years of messing around with this stuff it still can be hit or miss with how well something works. I do have planned for 2021 an update on some things I have learned since this video so check back for that every once and a while.
@@Zenodilodon Thanks man! I sure will! I am also planning on laying with this stuff. I know how oscillating circuits work, so i think i will just have to do some good old-fashioned research on this.
Can I use tvs diodes in lieu of the zener diodes??
As long as the clamping range of the TVS diode is at or below the voltage of the gate input you should be able to use them to protect your mosfets
Bro you did not show a zvs without senter tap does anyone or you have link for it I really want it
Thank you thank you thank you. I am a tinker and a lover of Tesla, you are the best that I have found. Thank you thank . I have accidentally found a circuit. I’d love to share with you.
Nice work. Jeremiah is a great soul. He shared my gravinductor here on UA-cam.
Can you do a deep dive into the plasma candle circuit ? I can’t find anything close to adequate regarding this topic .? Fantastic work on this one by the way 🙏
The trick with make a plasma candle is that it must be very fast, into the Ghz range and quite powerful. These are often done with large vacuum tubes and isn't something I have any experience with. Tested2Destruction might be able to help.
Very useful video thanks for that.
Could you make another video explaining how to build that full bridge configuration transformer driver with coupling cap that u showed on video??
A video on full bridge circuits is in the future, that particular board that I used in the video is a prototype though and has some minor issues. It's based off the SG3525 IC which is analogous to the TL494 and is a dual output IC. We used a totem to drive the P channel mosfets. The issue with the current configuration is in the phasing between the 2 sides and thus the mosfets get hot since there it not a solid off during the 0 crossing.
@@Zenodilodon since i don't have an oscilloscope I'm waiting for u to make an explicit diagram for that.good job bro keep it up
hello I love your guys videos and got inspired to make something like the plasma pen from your videos. I have all the parts but am having issues with it. a couple days ago I got the circuit running nice and it was throwing about 1 inch arcs running about 2.4amps@9.6v off a homemade zvs but the circuit suddenly stopped working while it was running and started drawing alot more amps and the arcs were gone. long story short I changed every single part on the circuit including 3 different sets of mosfets. and still same thing except I realized that there was actually output on the secondary but I had to short circuit it to get an arc and could only draw the arc out like a mm. while still pulling 3 amps from my batteries. and when I tried making a different inductor with a screwdriver the current dropped to around only 2 amps but still the same size arcs. do you know why this is happening? thank you
Glad to hear you enjoy the content. It sounds like your secondary has failed in an area and this is causing the draw of current and lack of output power. It sounds exactly what happens when we had breakdowns in our secondaries. A good way to manage this is to write the resistance of the secondary down. If that drops lower then you know it's done. There is also another way of doing ZVS which has a center tapped inductor, or 2 inductors of equal size attached to how the transformer is attached in this video. Than you just put a 2 wire primary transformer on the 2 outer taps of the inductor/s It works amazingly well. If you e-mail me I can send you pictures of how this is put together.
Alright can I get your email?

@@Zenodilodon ok ty
I sent you a email
I ordered a Transformer simular to the one you used in the plasma pen video, it just was about 16 times smaller but looked identical!
when watching this through again, at 39:49 subcaptions picked it up as "holy wow" idk if you did that or its just youtube, but its pretty funny.
@@JotticunChapter2 I watch the messed up subtitles, they are funny sometimes. I have seen them also omit strange stuff, like " None sense " was removed. I was like but why? 16 times smaller? That's like the size of a piece of rice.
@@Zenodilodon ok, ok mabey about 4 times smaller but 4 to th4 power of 2 is 16 soooooo i was really only 2 off
Hi... just a quick question..... when connecting the zvs driver to a coil, is it OK to keep the LEDs connected as a visual indicator of status??? Awesome channel BTW
Yes you can keep the LEDs connected, keep in mind that when the transformer is connected that you may have to handle both higher input voltages and ring up on the transformer's primary so I would advise using suitable resistors in series with the LEDs and consider using 3-5 volt zener diodes to protect them. Thanks for the complement and good luck on building your ZVS!
How many turns 5 0 5?
10 turns total with a center tap in the middle

Very good sharing👍
Sir this was an excellent video explaining all the underestimated facts , but the problem of dying mosfets still persists and if you have provided the circuit for the part where h use only one coil for primary it would be very beneficial.....
I just learned of that style which uses a regular transformer in conjunction with a center tapped inductor or pair of matched inductors.

@@Zenodilodon hehe, good stuff mate. Make sure you keep sharing your experiences. I keep zapping myself with capacitors still holding charge, so I'm steering clear of high amp designs for the time being. I figure at least a12 month period of no shocks before I step up the game. Lol.
Cheers.
Love this comment!
You say the negative voltage flows from the source to the drain... does the mosfet not show a flow from drain to source/ground for a low side npn? I've stopped watching until this is clear to me. I'm thrown off by saying a negative voltage flowing reverse through the source and through the zener.... maybe if you said electrons I wouldn't be so confused right now... what am I missing? (Btw I would have been stoked if you cut the whole face interview and just discussed all that with a bench view... only preference though since I watch so many videos like this.)
In real physics yes electrons flow from the negative to the positive, this is how I speak because it's applicable to other fields of understanding and models.
The electrons in this circuit flow from negative into the source through the junction and exit the drain. Zener diodes are only used for gate protection and do NOT conduct until they reach threshold voltage.
I also try to speak of negative and ground in context as if they are applied in floating or grounded systems. Ground is not the same as negative.
Refusing to watch the rest of an explanation video without an explanation, isn't that like holding yourself hostage for money kind of thinking?
@@Zenodilodon I get your analogy but everyone's situation is different right?. I'm 31 with a new hobby I've invested copious amounts of my savings into and you creators are my professors. If I misunderstand something in a video this long then I can't take in the proper remaining info. My kid just turned 4 years old. so since I first picked up a dmm when she was 2ish I've been limited to night time lab and study time. Since my career is unrelated, I try and use those nights as efficient as possible. That's why I held off watching at the moment... (I meant to delete this so I commented on my active channel I use for electronics.. feel free to delete this stuff and I'll do my response question to your other answer since I feel I asked my question a little more clear there. I'll give you a follow on both channels)
I will try to help out with answers, I am unsure how to format information at times my brain works very well with real time physics but trying to make a format style presentation or answer is nearly impossible for my head lol. In that sense I suck up information like collecting puzzle pieces hoping to eventually put them where they belong. This video is kind of like an attempt to dump out all the puzzle pieces on the topic I have collected. I myself just started getting into this power electronics stuff about 4 years ago in a more serious manor and it's still confuses me to a degree as well. I am by trade an optical/laser tech and have gone into this kind of stuff as hobby as well.
Is your other channel Steering Electricity?
@@Zenodilodon Yes. Starting a channel with my couple hours a night is hard. My kids finally about the age where I can get a little free day time sometimes so I just went and bought a nice multi camera setup and editing laptop so I can start posting with some consistancy and less filming struggle. They won't get many views since I don't do social media anymore but I mainly want to make videos on things I struggle to find on here. Hopefully help just a couple people dedicated enough to scroll through pages of UA-cam searches down to my couple views. Filming lab projects is tedious and frustrating sometimes when you just want to focus on the project. So kudos for the "fuck it, just post it all" upload.
Bom dia toligadinho no canal paulista Pernambuco Brasil
Can you say more accurately and more specifically about the diode you are using.thanks you
Any schottky or signal diode with the appropriate voltage rating will work. This is not a very important thing to consider and doesn't have to be exact, most diodes will work.
@@Zenodilodon so please let me ask more. I use mosfet p75n02 smd. input port G = R470ohm. and use zener diode 4.5 or 4.6 vol. is the 5v input port working properly? thank you so much
@@duongbui9621 There is significant ring up on these circuits, figure it can go up 4x when made properly. I typically use ZDs that are 15-19v as many mosfets have a gate voltage of 25v. This cuts down how much current ends up being dumped in the ZD and helps to maintain oscillation. I'd say using a 4.6v ZD is too low for this application.
@@Zenodilodon i want to make a pulse welding machine from zvs circuit. so, I have to use DZs 15-19v, right? and how much voltage the mosfet port will work. Sorry for not having enough knowledge in this field. Could you please help me
@@duongbui9621 Your ZDs must be chosen to closely match the gate voltage of your mosfets. Check on the data sheet for the mosfets you bought for the gate voltage and choose a ZD that is about -3 volts from that rating and you should be fine. If you are intending to use a higher voltage select a ZD that has a decent wattage rating for larger applications.

Sorry about that Well played. I wish I had a job but I'm happy staying home taking care of my lil girl and running various experiments and working as many side jobs ... any my ion drive with eight stage coil accelerators is coming along with lots of trial error and lots of reiterations because I know there's a better way to help put the thrust without adding 490 lb and only getting 3 times the amount of thrust when the original one was around 12 lb and output 92 million Newtons of thrust that's not bad now they just accelerate it with a multi-stage linear induction motor to accelerate the ions even faster Ergo more thrust im trying to do so all while remaining it under 20 lb trying to show NASA that you can get more thrust without making it 50 times heavier than the original ion drive that's on the dawn spacecraft right now so. any tips on how to get the most effective Corona with out the arc jumping across I was thinking about using an electromagnet to force spread the ark into more of a Corona what's your thoughts
I'm just saying NASA's MK3 Drive is a 500-pound slab of shit that's 17 x heavier than 3 MK1 drives that would have been just as effective and had the same amount of thrust if they had just used 3 MK1 drive so why spend like 7 to 18 years and probably a couple of million dollars on something that's less effective what the fuck
@@numatechprototypes222 Pulse your high voltage, you can get more power/voltage per distance in air and avoid break down discharge/arcs It needs to be fast.
