Kaizer DRSSTC III – progress update

Mads Barnkob — Thu, 12 Jan 2012 22:22:32 +0000

Here is a small update with some of the work that have been done on the large DRSSTC. This is my first project where I will post information and pictures about the progress as the project goes along. Normally I finish a project before doing the write-up for the homepage.

This update will show you the secondary coil that is almost done and the primary supports that was a failure.

MMC calculator added to the online calculators

Mads Barnkob — Fri, 25 Nov 2011 13:56:55 +0000

I have made a calculator for easily and quickly doing the initial design of the capacitor tank for SGTC, VTTC, DRSSTC and other Tesla coils with a resonant primary circuit. There is 4 basic inputs like capacitance, voltage rating and how many capacitors to use in series or parallel. Advanced inputs is detailed capacitor ratings and a few primary circuit values from your Tesla coil.

I hope you will enjoy this tool as much as it helps me do the quick calculations in the every day Tesla coil design where a online calculator is a little bit closer than all the spreadsheets that are deeply buried somewhere on your hard drive

2x 30 Watt EL34 tube amplifier done

Mads Barnkob — Tue, 11 Oct 2011 21:37:53 +0000

After about 2½ years, the amplifier now is connected to the destined Isophon BS35 speaker set and fulfil my dreams of beig able to listen to the real tube sound.

Kaizer DRSSTC II – upgraded and kicking!

Mads Barnkob — Sat, 17 Sep 2011 14:04:40 +0000

After driving the small TO-247 IGBTs so hard that they eventually failed, I have now upgraded the half bridge with a couple of IXGN60N60C2D1 isotop IGBT bricks. It is tuned much better now and is giving a fair amount of spark length, but I will need to spend more time tuning it for maximum output, but I am getting there.

So get in here and see the latest videos on the revived little coil http://kaizerpowerelectronics.dk/tesla-coils/kaizer-drsstc-ii/

Kaizer DRSSTC II – built, abused and broken

Mads Barnkob — Tue, 06 Sep 2011 19:30:34 +0000

I made a small DRSSTC which only lasted a couple of runs before the TO-247 IBGTs have to give up.

It gave a good 24 cm sparks will get upgraded in the near future with some heavier silicon for larger sparks

How to repair a LCD TV

Mads Barnkob — Sun, 04 Sep 2011 13:25:39 +0000

In this article I show how I repaired a broken LCD TV. A few bad capacitors in the power supply is enough to ruin a large expensive TV.

Read the article and gain inspiration to repair your own TV.

The Spark Killer!

Mads Barnkob — Sun, 04 Sep 2011 12:52:14 +0000

Salvaging electronics do not only work for supplying your hobby with cheap parts, also cheap laugh

Here is a on/off switch from a 1980′s transistor radio, having a capacitor across the AC terminals is not strange and will protect the circuit in some degree from surges on the power distribution network.

But naming such capacitor a Spark Killer on the PCB is something new to see for me

Have a nice weekend, I certainly have one

Isophon BS35 speakerset complete

I have finished the speakerset built for my upcoming valve amplifier and you can read all about the construction in the article by following this link:

homopolar motor

Mads Barnkob — Thu, 04 Aug 2011 10:17:17 +0000

This morning I made the simple experiment first demonstrated by Michael Faraday in 1821, the homopolar motor. It is a simple electric motor that anyone should be able to make from common household items.

Enjoy

Kaizer DRSSTC I, updated with schematics

Mads Barnkob — Fri, 22 Jul 2011 11:48:12 +0000

I have uploaded the bridge section schematics for the Kaizer DRSSTC I Tesla coil. The driver section will have to wait for me to find time to draw them on the PC, for now they exist only on paper.

Progress on the Isophon BS35 speakers is going smooth without problems.

A TL494 inverter and current monitor is giving me some trouble at the work bench

4 weeks of vacation ahead of me!
