Moving day

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

SAIA PCDII

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.

One of the output modules

I desoldered the ICs to work out the schematic

Eight output boards in the extension case

 

Unfortunately I just this one picture of the pin out.

out of focus and confusing pin out – sorry

TODO:

  • redraw schematic
  • Figure out connector type

Manfrotto 323 vs. ebay clone


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.

Instagram

As some may have noticed I don’t post often here. Writing here takes time because I want postings here to be a bit more elaborate.
That’s also the reason why it’s been silent here for much of the last year. There is more to come but this takes time
If you want to keep up with my shenanigans in the mean time I would like to point you to my Instagram account where I post more and on a regular basis.

greetings, Chris

Feelworld FW597 Field monitor – DIY AV Cable pinout

I got myself a Feelworld Field monitor since I want to improve my Youtube video game a bit.

But first I needed to build a AV Cable to connect my Olympus Pen camera to the (legacy) 3,5mm, 4 ring AV jack of the FW597 since olympus Pen camera do not support live video HDMI output.

Long story short, the pinout:

1, Ground
2, Video in
3, Right audio channel
4, Left audio channel
(1 being the ring at the base of the plug and 4 the tip of the plug.)
