Hello All

Just wanted to tell you a little about my high voltage, Tesla coil and general electronics website. 8 years of projects and data

It contains schematics, pictures, instructions and videos of 10 Tesla coils of different topologies, a DRSSTC design guide on how to chose components for building such coils. Another 10 smaller high voltage related projects, 3 tube amplifiers, many online electronics calculators like IGBT gate drive, transistor base resistor, MMC calculator and single layer coils. Theory pages with data lists, file archive with a good collection of application notes. General electronics and everyday experiments.

Thank you very much

A new article has been added that describes the thoughts, design, construction and test of a very high impedance primary circuit QCW DRSSTC, where the voltage ramp is coming straight from half wave rectified mains supply and a mains synced interrupter is used to trigger at the right interval.

The article covers the fall pits and strange behaviour of Tesla coils driven in this manner.

The project is highly experimental and the results were not as satisfying as expected, but problems with switching transients was a much bigger issues than initially thought of.

Read it all, see all the pictures and view all the videos at: https://kaizerpowerelectronics.dk/tesla-coils/kaizer-drsstc-iv/

I made a new channel trailer for my youtube channel, which is more action packed than the old one, what do you think?

It's better now, but since you asked, I'll put in my 2-cents... You look a little rigid and need to loosen-up a bit. Also, stop looking up to your right before cutting forward. Fasten your eyes and maybe experiment to see how a brief mischievous eye works for your style (you may not be comfortable with that so try what works for you - but be sure to hold the eyes till the first cut).

Since HV is kind of risky and exiting stuff, a continuity of background beat music is catchy (volume and edge should suite you not anyone else). Raise and lower background volume to not compete with voice-overs and effects. Since it's short, make sure cuts are fast with some light-flash cuts and definitely in-sync with the rhythm. Maybe some help here.

Lastly you may want to cut down, break-up or even lower the long spark sound at the beginning, since noisy intro's get old pretty quick when returning to the channel (but it could be just me the semi-retired schlager musik fan).

Thank you for the feedback.

I know I am a little stiff in it, I think it comes from English being my 2nd language and maybe a little stage freight, handheld camera as I do not even have space for a tripod in the cramped lab So I spend too much brainpower on keeping camera still enough, to keep my head in the shot etc etc. I never make a script beforehand, I do retake some scenes, I often feel the big disadvantage of being alone to do both experiments and filming, its hard to do both really good.

I do try to be more happy, less dry in my speech and so on, but damn its hard when it gets technical

Problem with music and youtube is that they will almost instantly slam you with a copyright claim, so I just stopped using it, maybe once I build my sequencer/VCOs I can make my own, but it will hardly be any good. Even royalty free music / commercial free music does not go free of this.

I made that splash screen with spark sound as my trademark, as you have seen on many videos, lowering the sound and shortening it to 2 seconds will be tried in the future.

[madsbarnkob]

I did some more experiments and teardowns, I also made a new intro splash which is used in these two latest videos





I have been working on getting better audio (external active microphone on DSLR), unless its handheld smartphone recordings and lightning, but a 10 sq.m. lab that contains 9 sq.m stuff really makes things difficult, but I do not want to let that stop me from making videos

Happy new year to all the readers, followers, subscribers, liker's and users that has to do with reading, commenting and writing on kaizerpowerelectronics.dk or highvoltageforum.net

I have filmed a small new year special video for you all! See you all in 2018 for more high voltage exploration and experimentation!

[Cliff Matthews]

Well done and happy new year to you and your family!

[madsbarnkob]

I bought a house and that is why updates have been rare, as I went into deconstruction/construction mode. I have however made a few small videos along the way to show the progress of moving all the electronics and get settled in a new work shop/lab.

Before moving out


Moving out


The new place


Some kind of order is restored in the work shop

[madsbarnkob]

There has also been a lot of teardown videos etc, you can find that on the channel

Seems that I forgot to post part 5 long ago, so here is both part 5 and part 6





I am operational again!

Part 1 and 2 of a little series on a 750W solar project I am currently testing/building.

[madsbarnkob]

A teardown of a ESAB Caddy 1500i TIG welder, a run down of the current paths in the system and I show which parts I kept.

Datasheet on the unit: https://www.esab.dk/dk/da/products/arc-welding-equipment/tig-equipment-cc/industrial-equipment/caddy-tig-1500i-2200i-ta34.cfm

 In part 3 I test the setup with all 3 panels connected and look at the performance over the last 8 days.

It all consists of:

3x 250W solar panels

1x Victron SmartSolar 100|30 MPPT battery charger

2x Norbatt 12V 150Ah batteries

1x 750W 24VDC to 230VAC inverter

[madsbarnkob]

Teardown of the Siemens Polyphos 30 X-ray head which contains step-up transformers, voltage multipliers and a rotating plate x-ray tube and a lot of oil!

[madsbarnkob]

Teardown of the Siemens Polyphos 30 collimator and image plate. Collimator had an interesting moving blinds design with a lot of gears, pulleys and strings. Image plate has a lead grid and some kind of sensor.

[madsbarnkob]

Teardown of the Siemens Polyphos 30 X-ray systems control panel including computer, safety functions, HMI and high voltage inverter circuit.

I found a old 3.5" floppy drive cleaning kit and tried it out on a defective computer/floppy drive/floppy that I had. It would constantly ruin "new" disks and leave them with few kb of useful space.

Teardown of a Nokia Siemens Networks Flexi Multiradio base station. This have been in service as a 3 antenna system for mobile telecommunications.

GSM/EDGE, WCDMA/HSPA and LTE capable. 3x90 Watt output power.



Flexi RF Module Triple (FXxx)

The Flexi Multiradio Radio Frequency Module (FXxx) or RF Module, is a 3-branch multicarrier,multi-standard radio transceiver module. The module consists of three independent branches, capable of transmitting and receiving signals of multiple radio technologies concurrently:

    Up to 6 GSM carriers with 400 KHz minimum carrier separation
    Up to 4 WCDMA carriers with 4.6 MHz minimum carrier separation
    Multi-carrier LTE signal with 1.4 MHz, 3 MHz, 5 MHz, 10 MHz, 15 MHz, 20 MHz, and 35 MHz carrier bandwidth
    Multi RAT operation with combination of GSM, WCDMA, and LTE

The RF Modules FXDA, FXDJ, FXEA, FXCA, and FXFA/ FXFB are referred to as 70W RF Module variants. RF Modules FXEB and FXDB are referred to as 90 W RF Module variants. Each branch consists of a transmitter and two receiver chains. FXxA and FXFB (70W) variants have front end software tunable filters (STuF). 90 W RF Module variants have fixed full band filters. FXxx is a 3U high module with an integrated, replaceable 3-fan assembly for module cooling. The supported functions are:

    Chaining up to three RF Modules with OBSAI RP3_01
    2-way receive diversity in the receiver chains
    Integrated antenna line supervision
