Hey thanks somebody else!
I don’t want to appropriate the thread but I think it is an interesting subject, so let me explain a bit further my view.
I still don’t see it is any easy (not for me at least) to make a working remote volume knob. The first link in post #26 describes how to build the IR receptor, fair enough, but besides the programing, I consider the receiver side the easy part. I use a flirc dongle that is very small, available and very cheap, probably cheaper than the parts needed to build any diy solution. The second link in post #26 describes how to build in the knob, but I still see a cable there. If the solution needs a cable (the guy in the link in post #24 explains this further), well, there are many options available already built and not expensive. I think the objective here is a remote and wireless solution.
So far the only complete solution is that in post #24, that is great, but a couple of levels beyond my skills. The guy even printed his own PCBs…
I am still aiming for an easier solution. So far I have gathered:
- Bluetooth based: there are available knobs (i.e. the surface dial), and for instance raspberry pi, that can run many different streamers and players, already has the receptor built in. So all the hardware is there, it is a matter of making it work. But besides what minidsp did with the SHD and a “DIY/commercial” solution available only for Roon, I am not aware of an easy way of making one of these work with any other streamer/player.
- IR based: the problem here is the sender. Again, I am not aware of any existing IR volume knob. Post #24 looks great, I would instead print a round and as small as possible PCB and have a good quality round enclosure 3D printed, but that is definitely not something I know how to do or get done. But hey, if someone is up to a shared project, I am in!
