Hello all,
I've been a 4hv member since.. 04? Figured I would venture to this forum to see whats new. I studied electrical engineering in college, then went to work for a medical device manufacturer designing buck converters and digital circuits. Done a lot of microprocessor design and written a lot of firmware and some computer software.
I got into electronics when my dad showed me a magazine article of building an electric fence. Been hooked ever since. Played with HV and coil guns for a number of years. Now trying to start my own business off an energy storage idea. I look forward to contributing, learning, and helping others learn.

Good to see you.Oh, hi Alan – I know this good fellow. :D
Hi everybody!
I am 17 years old, and have taken an interest in the electronics hobby since I was about 6. I am from Australia, and have just completed year 11. I have previously built a small SSTC, and am now working on my first DRSSTC. I've joined the forum primarily to seek advice on the DRSSTC (not going quite to plan at this stage... :P), but I also hope to stay around, and help others. :)
I look forward to getting to know you all.

Hi black.yang and welcome to HVFThanks for your warm welcome.
Impressive coils, outstanding work on the digital driver and great to have someone on the forum that understands Chinese, as you could see in the aliexpress driver thread, we do have a hard time when all we have available is google translate and sometimes a lot of text comes on pictures.
Please do make a thread or two to show some of your best coils, I took a look at your youku account (Chinese pendant to youtube?) and you have a good variety of work there.
Hi, everyone.
I am a 24-year-old Tesla coil hobbyist from Wuhan, China.
My job is Chip Technology Support Engineer.
I have 11 years of Tesla Coil hobby experience.
The first Tesla coil was made by winding the coil with a mineral water bottle. The arc was only 2 cm. ;D
At present, I have done DRSSTC, QCWDRSSTC and some CLASSE design experience.
I just finished the design of "Yunbao" jump pulse driver the year before last, see it

Recently, I am developing UD3.3A for full digital signal input phase shifting.
At present, I am completing the work of writing the hardware logic of the phase shifting part of the alternating hard switch bridge arm.
Hope to share with you more! Thank you! :D
Hi Shrad and welcome to HVF
Got any high voltage projects going on for the hobby or professionally?
Hi All,
Looking forward to many interesting discussion.

Hello, I'm a Tesla coil enthusiast from Lanzhou, China. I like electric arc.
Hello all, well I just read thru all the "Welcome new members " posts and have now understood why 4hv hasn't
replied to my registration, a few of them are here!! 8) To start with, I am 56 yo service tech for Phenix Technologies in Maryland. We manufacture High Voltage, High Current, High Power test equipment and components. Started learning about electronics about 9 yrs old, spent a lot of time at Radio Shack and reading their books, then more formal study in high school. Went into the military and got more formal study at TOFTOY
at Redstone Arsenal Huntsville, AL. My MOS was 27E, TOW/Dragon missile guidance technician. After military
I went to College and got my Associate Degree in electronics. My passion is HV and working on a frankenstein
SSTC that is mix of Steve Wards SSTC-5 and a few others. As I mentioned I am a service tech, I travel a great
deal around the world, and COVID has put that to a halt. So lots of time to get frankenstein spitting lots of PD ;D. I hope to learn more from you guys and contribute to this forum. It's great to be here!
I tried to log onto 4hv but couldnt happen, I tried change pass word arghh got a new connection so old email has gone,
anyway Im here , Paris form NZ
see familiar names on here
Hi Daniel
Welcome back! It is a pleasure to see you here on HVF!
I also have wife and two kids now, but still managed to keep a good 50 sq.m. of work shop / laboratory, the only problem is always running short on time :)
Hi Matt
Good to see a old familiar face here on HVF :)
I've seen your latest magnetron videos, been a subscriber for very long! It is nice to see that you use a faraday cage on it, not many people driving magnetrons take that care.
Welcome to HVF Matt!Well thank you so kindly! It is truly great to be amongst other 4hv members. I started 4hv when I was 13 and I am so incredibly thankful for all fellow enthusiasts for getting me so deeply interested. I need to get on the IRC channel again! I used to spend hours speaking to others on there, thanks for letting me know!
Its nice to see some more people from the old days when I was first getting into electronics. The IRC channel is still active.

We need help because we don't know ANY of it when it comes to DRSSTC's. But we both learn extra fast (we are pretty much Indigo persons i guess) and we are really smart if we really focus on something. This said. Thx to everyone who is gonna help us out, and i'm sowwy if my english suc*s... But we are from Italy so we try our best over there.. Love You All 💗✌🏻🏳️🌈Welcome! Since you are interested in learning, I suggest learning an analog circuit simulator. There are free online versions and free ones to run locally on your computer. My favorite is LTSpice. Testing circuits in simulations allows much more experimentation without burning out real parts. Any voltage or current can be plotted. Easier than connecting real scope probes. Then, when you construct a real circuit and probe it, you can compare measured waveforms with simulated ones. That helps with figuring out issues with real circuit (such as excess wire inductance that isn't in the simulated circuit). Simulation is not a requirement to make a working DRSSTC. We can help interpret issues from scope traces. You will learn more about electronics, however, if you run your own simulations.
Recently I launched website devoted to my projects: https://huntergroundmind.wordpress.com/Wow, impressive projects! Thank you for sharing.
Hello everyone.
I'm Andrea and I live in the north of Italy. This is my first post on this forum after spending something like 5 years reading it without ever being a member.
Tesla coils always had a place in my heart and I now have a working (and excellent performing) DRSSTC. I'm planning to make a thread in the future about it to show my progress and to thank everyone that helped me.
I hope I didn't break any rule as this is my first forum ever :)
Best regards,
Andrea
Thanks Mads, as a huge styropyro fan i feel like it's pretty important to document the build process of my coils, as it helps people who are not into the niche hobby of tesla coiling and somehow found my videos start to understand what the heck a tesla coil is and how it works. also it gives me an excuse to make sick build montages with dubstep music lol
Also btw where should i go on the forum to discuss induction heating?
Greetings all
My names Kevin, and I have recently retired, and am the creator of the biggg Tesla coil of Oklahoma. Last Fall I retired the coil after running it 23 years, it was time. It produced hot 26 foot sparks {point to point} thanks to its 14 gage secondary wire. I miss it already. This Winter I will be looking into its replacement. I have been building coils since 1992 in Oklahoma on a 5 acre homestead.

I seem to be in a very similar boat as you, finding the HV hobby in my teens and wanting to return to it with more experience/resources.
Your nuclear hobby sounds interesting and I would love to read your blog and/or paper once released. I am currently riding the nuclear fusion startup wave that has high demand for pulsed power engineers. No background in anything nuclear before this though, so I am curious to learn tidbits of history along the way.

I've since purchased a cheap oscilloscopeAlmost any issue can be figured out with proper scope captures. Much harder to guess what an issue may be through just pictures and DMM measurements.
I plan on building a Plasma Toroid circuit, and after studying quite a bit of the works of people who have built, and designed similar circuits, I figured this would be a great place to document and share these designs.Yes, there are certainly active members and discussions here. Would love to learn about your build. Plasma toroid experimenting is on my list of future some-time projects. At least initially I'll use argon because it is cheap and I can easily play with pressure. Do you have a good source for a glass globe filled with xenon or other gas mixture?
Hopefully, this is a good place for this and there are still active members.

I purchased my globe from Wayne StrattmanLooked at that web site. Didn't find any specs other than xenon and 2-liter. Is fill pressure listed? Glass thickness? If you have a scale, weight would allow an estimate of average glass thickness. I gather that typical xenon pressure for toroids is 15 to 50 torr.
https://strattman.com/
I ended up going with a 2-liter Globe filled with Xenon.
Which forum would be best for my project?Good question. Hope others will respond here. I don't see an obvious fit. Some previous plasma toroid posts are within the SSTC topic.
But I plan on doing a lower-power version and using Mosfets / IGBT.Frequencies for plasma toroids are generally far too high for IGBTs. Most use either standard Si or faster SiC FETs. I'm planning to use an SiC FET when I eventually get around to experimenting.
Eventually, I'm gonna power it with tubes.Tubes are more forgiving of mistakes. They don't fail as instantly as do FETs. Might be less frustrating to use tubes from the start if that is final goal.
And if it is allowed, I would love to involve the community in a discussion of the theory involved.Yes, definitely. There are physicists on the forum, at least one besides myself, probably more. There is some theory discussion in this existing plasma toroid thread:
I have so many wild questions, and don't mind being corrected, especially by competent engineers, who can teach me how to do it properly.Yes, the forum is definitely for questions, not just display of projects.
