You've inspired me on this one and I'm vaguely looking at setting up something similar here.
I have a 4 port relay, but it's not directly controllable by USB. They are fairly trivial to control by way of an Arduino though and I have a few Nano's here - cheap clones - 5 for 15 euros kinda things - so happy to sacrifice one as it may work out quite well for some lighting in my basement.
Unsure about the control of it though - it would be nice if it were kinda self contained (ie: no requirement to add a fixed computer into the mix), so vaguely considering infrared, bluetooth or network (would prefer one of the latter as it doesn't require line of sight and could be controlled from my tablet/phone). Alternatively, I could probably use a Raspberry Pi (preferably a Zero if I could get hold of one...). Also been toying with the idea of just hacking up a clap clap switch of some sort to do it - having a working prototype of that, but it's not very reliable at the moment.
I didn't find double sockets like you have them though - all rather clumsy single sockets, so I suspect it'll make a larger box to shove it all into
, but I might give it a crack.
The current set up uses
Chacon Dio's and while they work OK, I'm constantly searching for the bloody remote
. Controlling it from the phone, tablet or even hacking my media player to incorporate the functionality somehow would be kinda fun at least and it would free up the equipment for another use which I had in mind.
The room in question kinda looks like this:
and it's the lights (Ikea Dioders) which are obscured by the white paper which I would like to have more control over.
Also need to replace the white paper with some 3D printed thing
- they're there to keep the light from the shelves bleeding on to the projector screen, but don't do a great job.
