B16S22 tube info
A guy on a forum I visit wanted data on this tube. Note: it's only a pinout, and similar tubes to illustrate the functions and meanings of various pin names.
The Nixie Power supply
WARNING: This device deals with high voltages. It is very unwise to build it unless you fully undestand it and are aware of the risks. I take no responsibility for whateever you may inflict upon yourself and/or others directly or … Continue reading
The nixie clock V0
As a fan of retro electronics I found it very nice to have a nixie clock. So I'm building one. It will have a few Z560 nixies and will be driven by 2x HV5630 chips. Ofcourse, it will be AVR … Continue reading
The RETRobot – the first robot with a CRT tube
The RETRobot is a robot I designed. You may have noticed something odd on it – it’s got a CRT tube on it. I always wanted to play around with one. I didn’t need an oscilloscope – I already have … Continue reading

The IBM 7864: A data collection terminal. While looking for something else I came upon these buggers. They've all got a 8088 processor, a barcode scanner and fail to boot up. Only 1 of 3 was functional, the rest had broken … Continue reading
Old storage media
I've collected some interesting storage devices over the years. Behold 🙂

Soviet C-112 scope
The C1-112 oscilloscope: A simple soviet scope. AFAIK it is a copy of a french scope. I have the manual. The schematics part is available for download. It is very large, namely 10MB. So be careful when you decide to … Continue reading
Czechoslovakian mystery keyboard
I got this device from my school, from a friend. It looked interesting and I needed (OK, maybe not needed, but was very interested) to know what it actually was. So, here's the thing: write into the guestbook what you … Continue reading
Soviet missile punch tape interface
I like cool stuff. I can't resist exotic electronic vintage parts, and what's more exotic than a programmer for a military rocket? On my frequent visits to a local electronics fleemarket, a guy who sells radioamatuer stuff offered me this … Continue reading
