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.
Urban Cricket is a small circuit that imitates the call of a cricket, only being powered by a small solar cell. The idea comes from Reinhard Gupfinger a Linz based artist I met during the Ars Electronica Festival 2011 in Linz. This circuit here is a altered version of his original circuit. He distributes this little sound bugs all over the world. Until early 2013 on was in a tree at the Schwedenplatz in Vienna.
