Writing process and site updates

I am currently working on a DRSSTC design guide where I try to put together best practises, lessons learned and explanations to the different solutions used by many people. It is not a from A to Z guide on how to go from ebay to 4 meter sparks, but a hole bunch of snips and snaps of interesting theory hand picked for just DRSSTC use.
It is currently at 10 A4 pages and I expect it to end at around 20.

Updates to the site.

Interesting datasheets and application notes have been added to the file archive.

Aerovox RBPS snubber capacitor data added to the good MMC capacitor list: http://kaizerpowerelectronics.dk/theory/good-mmc-capacitors/

Wire table updated with 100% skin depth frequency values: http://kaizerpowerelectronics.dk/theory/wire-size-table/

Transistor base resistor calculator updated with PNP transistors: http://kaizerpowerelectronics.dk/calculators/transistor-base-resistor-calculator/

Happy new year!

I hope to learn even more about electronics in 2015, I hope I get to build more projects and I hope that I have the time to publish it all for you to read, comment and build for yourself.

Happy new year 2015!

4kJ capacitor bank videos

This is the first test of short-circuiting 1800VDC from a 2500uF capacitor through a mini circuit breaker to see what kind of damage a high energy surge current do to the protective equipment in electrical installations. 4kJ of energy released in 200uS.

You can see all 4 new videos at: http://kaizerpowerelectronics.dk/pulse-power/4000-joule-capacitor-bank/

File archive added to the site

Through this hobby I get by many interesting papers, documents, calculations, manuals, datasheets, designs etc.

I do also find stuff, take pictures of stuff and do all kind of other stuff that never really gets big enough or done enough to get its own article on the website.

I have so many spreadsheets with calculations for all kinds of electronics that I was designing. Small tools that could help others, but need a little shining up first.

Instead of just having all this information on my own hard-drive, I have started sorting it out in a file achieve on the website so it all becomes accessible to others.

I hope that someone will find something useful among it all, but please be patient, it takes time to prepare all the random notes and spreadsheet for publishing

You can browse it like any folder structure or use the search field.

Project updates #3

The radiation monitoring is back up and running after a small upgrade of the 400V inverter choke which should make it run completely stable again.

I repaired my 15 year old Texas Instruments TI-83 calculator and it is almost as good as new, taking its hard life in a school bag into account this is really doing well after so many years and a small repair is the least that could be done for it.

The large DRSSTC is currently on a bit of hold while I am waiting for some laser cut parts for the topload construction, so unfortunately nothing new to add here.

I have received new enclosures for building a set of two mono tube amplifiers out from my 6P45S tube amplifier prototype and already have the power supply and mono stage circuit boards etched and half way populated with components, this will get its own update later.

I am also working on a couple of new online calculators for secondary and primary calculations for designing Tesla coils.

Kaizer DRSSTC III tested at 1500 Ampere peak

A static load test was conducted with the large CM600 DRSSTC inverter, a container with water was placed instead of the secondary coil and inverter was running at 320VDC at 1500 Ampere peak current.

uRADMonitor live from Odense, Denmark

uRADMonitor is a network connected monitoring station, focused on continuous Environmental Radiation Surveillance. This capability is delivered by a digital dosimeter constructed around the highly sensitive Geiger Muller tube SBM20U.

This is a uRADMonitor that I have installed outside of my appartment in Odense, Denmark. The system is currently under development by Radu Motisan from Romania.

To see the 4 other graphs from this monitor see the article: http://kaizerpowerelectronics.dk/everyday-science/radiation-monitoring/

To read much more about this project, visit the projects development page http://www.pocketmagic.net/2012/10/uradmonitor-online-remote-radiation-monitoring-station/ and the official site can be visited at http://www.uradmonitor.com/

100 Watt output from 6P45S tube amplifier

The latest update to the 100 Watt 6P45S tube amplifier is the measurements of frequency response from square waves and bandwidth measurements.

The prototype is now considered done as it has proved itself capable of outputting 210 Watt peak before clipping. At 100 Watt peak it have its -3dB points at 11 Hz and 72 kHz.

Due to a busy work year and not many days at home the progress with the large DRSSTC have been very limited. I have however updated the article with the testing progress and fault finding that have been done. New video and pictures can be seen here: http://kaizerpowerelectronics.dk/tesla-coils/kaizer-drsstc-iii/
