I would really like one of his BeoIR cables - http://web.archive.org/web/20140827063221/http://home.swipnet.se/ridax/beoir.htm - but likewise have been unable to contact ridax. It looks simple enough but without knowing what the IC is it's a little difficult to build...

It's likely a small microcontroller (PIC or similar) so you would need the program code in it as well, the schematic alone isn't going be of much use.

Yes, this was my suspicion to be honest. Although not having investigated whether the data is anything more than a duplicate of the received IR from the associated remote, the other possibility was that it was some form of line driver.

I have now managed to obtain a remote for my BM3000, so at some point I intend to get the logic analyser out and take a proper look - trouble is, it's one of those jobs that never seems to reach the top of the to-do list! 🙂

Hi everyone!

I am sorry that you have difficulty in obtaining the cables and stuff.  I hope you can understand that I have had a lot of these kind of projects in the past but that is not much activity from neither customers nor myself on a lot of them.  Sometimes someone mails and request a cable or something else for an old project, but I have no longer any organized stock for the parts needed and have forgotten most of how the parts are built and tested myself.  This doesn't mean that it is impossibe for me to make them, just that it takes a lot of more effort to do so compared to what it was like when it was "new and hot" (if it ever was).

Unfortunately this makes it more expensive and requires much longer lead time, to order the necessary parts and honestly, in the last years under these circumstances, I have spent many times to check up the possibility to make parts, just to receive no interest once it is has been checked.

I have also moved to UK (Oxford-area) for some time, and a lot of my equipment is not with me, but still in Sweden, so I often have to wait to see when I will be back to Sweden to pick up required equipment or to program microcontrollers and so on.

The reason I am even answering in this thread, is that I remembered the last one requesting the BeoPC cable and now I have been temporary back in Sweden for a week and remembered to check my stock for old BeoPC components and just searched the Internet for the BeoPC project to see what the cable looked like and it landed me on this thread.

I don't know if you have already covered your need, or if you are still interested.  I have collected a couple of connectors and components, and think I could do this cable if needed.

I do not remember any recent request for any of the PIC-based B&O projects though.  As mentioned earlier in the thread, duplicating the circuit for a PIC based project is pointless, as the microcontroller contains software which does all (?) the actual work.

Hi Ridax,

I still want one of BeoPC cables if you can help.
