Recently I found a broken HP elitebook 820 in the electronics junk at work. The notebook was already cannibalized for parts but the display still looked good.
In the upcoming days I will move this website to a new hosting provider.
This means it will not be available for some time
Looks like it’s done now
Main goal was to enable https which seems to work now
Disclaimer: This posting is a work in progress. I’ve mode this some years ago and was asked to provide some documentation:
I have parts of a SAIA PCDII that I wanted to make use out of. The ourput boards have 6 relais each and 8 of them are connected to a backplane connector. This makes 48 mains voltage (low current) switchable channels.
Confusing what I mean? Have a look at this video
I’ve found some of the pictures I took while working on this and just a few days ago I found the box with the hardware itself.
For now the old pictures.
Unfortunately I just this one picture of the pin out.
- redraw schematic
- Figure out connector type
- sketch pinout of PCD2.A220 board
- sketch pinout backplane

I got both a genuine Manfrotto 323 and the 12$ ebay clone and took some pictures for you to compare. The Manfrotto one looks more valuable. The release lever of the clone is a bit loose bit holds the plates in very well. The Manfrotto plates fit the clone very well too.
I think the clone is good enough for what I’m doing with it so I will stick with it.
I needed to make an AV-Cable for a monitor but the vendor did not supply an appropriate cable so I had to make my own cable.

What is this all about? Many old video camera (VHS era) are equipped with tiny black and white CRT screens as viewfinders. It is exactly these this posting is about. Many of them can be hooked up to a BAS or FBAS (Yellow RCA connector). Such as CCTV cameras or a Raspberry Pi to be used as a tiny screen or with the magnifying viewfinder assembly you can put it close to your eye and have a much larger image.
I made another Infrared vs. RGB comparison but this time with different wavelength Infrared-cut filters.
I took this pictures on 14th Nov. 2015 at the Alte Donau subway station in Vienna/Austria.
You can click the knob (< >) and move the slider. By clicking the buttons you can load different wavelength images and their description texts to compare.
