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.

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

Live measurements: Counts per minute
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:
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.

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:
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.

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.
