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/

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.

DRSSTC III update

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/

6P45S tube amplifier prototype

I have completed building and initial testing of a new tube amplifier prototype using the Russian 6P45S tubes in the output stage.

This prototype will be used for testing, tweaking and a way to perfect the amplifier before building the final version.

Read more about the amplifier, the progress and see the pictures at http://kaizerpowerelectronics.dk/audio/100w-6p45s-monoblock-tube-amplifier/

TL494 flyback driver

It took some years and someone recently bumping up my old thread about this project for me to write up a article, find the pictures, make a video and get it on here.

Read all about the design and construction of the TL494 flyback driver here: http://kaizerpowerelectronics.dk/high-voltage/tl494-flyback-driver/

DRSSTC III update

Being the lucky person to suffer from having a work, there is little time to maintain building on all the high voltages apparatuses. None the less there is still progress and here is some of it for the large DRSSTC currently under way.

All the pictures can be seen at the bottom of the page: http://kaizerpowerelectronics.dk/tesla-coils/kaizer-drsstc-iii/

Royer induction heater – first test

This is the first test run of a royer induction heater running at 650 Watt, there is heavy voltage sag on the DC supply. The heated bolt is a M10x20mm. More to come when improvements are carried out.

Another TV lives again!

I received a broken 27″ LCD TV and repaired it. Read the whole article in order to see how it was done and how cheap it was done.
