Hi all, this is shrad, migrated from 4hv to here since the place was not alive anymore...

To introduce myself a bit in this new place, I'm an IT guy, electronics guy since the young age, I have had enthusiasm for high voltage for many years, I'm a science enthusiast and self learned in many subjects like lasers, spectroscopy, valve amplifiers, etc...

I'm interested in all technical aspects of all domains, active in local associations and launched some local things like a collective vegetable garden and a repair café in my village

Last but not least, currently workin at a major grid management company in Brussels as a contractor, which is somewhat related to the interest I have in HV :)

Hi Shrad and welcome to HVF

Got any high voltage projects going on for the hobby or professionally?

Not for the moment, except maybe some tube amplifiers which are waiting to be designed and built (some GU50 would be glad to go out of their box)

Right now I'm distilling ideas on a guitar amp based on a mosfet follower with high amplitude preamp to experiment on a more qualitative approach of guitar amps

Hello everyone. I've been doing electronics on and off for about 10 years. I've been in the power supply industry for 5 years now.

I made a small solid state tesla coil in college in 2010. Ever since then I've been trying to design something new, but could never keep up with Steve Ward and everyone else- especially on such a low budget. Between that and life taking me through many twists and turns, I never really got anything else done.

Now that I have worked a few power electronics jobs, including high voltage and radar, and my life has stabilized, I'm ready to get back into it! The catch is that I don't have much time, but I have a pretty good budget. Not to mention, I'm actually knowledgeable about the stuff, now!

My first goal is to make a handheld lightning gun, like Steve Ward's. I can't wait to post my progress here.

Hi there. I'm another shiftee from 4HV.org.  Came looking for a more active forum.
I've been a professional electronics engineer for over 30 years now, but I've been messing with electronics since I was about 8. I'm also interested in physics and chemistry, PC gaming, gardening and sea fishing from my kayak.
I live in New Zealand with my wife, two daughters, three cats,  two rabbits, 7 frogs, and however many wild ducks my daughter is feeding at present.

Hi All,

So I am Jeff and I live near to Bristol in the UK.

I have always been interested in electronics but decided to go for Chemical Engineering as a career, now I try to keep the hobby going with a handful of projects.

I found this forum while looking for info to help with my 2500w induction heater project - lava maker as my 6 year old son calls it!

I have attached a picture of my latest induction heater setup, this used 8 off 750W 12V server PSU (2 in parallel and 4 series) to give a de-rated 3kW unit operating in 12, 24, 36 and 48V increments. The first unit with 4 PSU in series needed to be de-rated and didn't survive!

I also included a solid state relay for simple on/off control, 50A RCD for over current and a bunch of 4mm RC bullet connectors and 10AWG silicone cable.

Looking forward to many interesting discussion.

Jeff B

Welcome to all new members on HVF, good to see you pop inhere and give a word or two about yourself.

@Johnf, I hope we get a share of your huge experience, that is a serious business end you are in where high voltage/current/frequency is actual in commercial use.

@Coupling, A portable handheld QCW is no easy task, looking forward to see how you execute that project!

@Twospoons, do you have any projects going on that we will get to see?

@Jeff B, the induction heater threads have really taken off with experiments with the, now so cheap, Chinese units, so good to see another chime in with more experience on using these.
