nerd alert
Jesse Morgan
I pride myself on being a geek, but every once in a while I do something that can’t be described any way other than “Nerdish”. Today I think I crossed that line again.
1) A while back I hooked up my old PC speakers (kinda nice) to my server in the basement, then streamed music through it. Well, this was fine and dandy for me, but jackie wanted “her” music.
2) I set up a web interface with several radio stations that jackie could select from with HTML “radio” buttons. This worked great, but it still required a laptop to hit the web interface to change channels.
3) A few years ago I bought a nice soundcard to attempt to record my guitar playing on my workstation- that never panned out, but the card came with an USB IR receiver and a dinky little remote for watching DVDs… well, I got the remote working in linux (on my server) with lircd. I then have irexec listening to the lircd socket for buttonpushes, and executing commands based on my config in /etc/lircrc which liiks like this:
<br></br>begin<br></br> remote = Creative_RM-1500<br></br> button = Vol_Down<br></br> prog = irexec<br></br> config = amixer -c 0 -- sset Master playback -1dB+<br></br> mode = order<br></br>end<br></br>begin<br></br> remote = Creative_RM-1500<br></br> button = Vol_Up<br></br> prog = irexec<br></br> config = amixer -c 0 -- sset Master playback 2dB+<br></br> mode = order<br></br>end<br></br>begin<br></br> remote = Creative_RM-1500<br></br> button = Mute<br></br> prog = irexec<br></br> config = amixer -c 0 -- sset Master toggle<br></br> mode = order<br></br>end
The end result? it raises and lowers the volume and can mute the audio on the server… what’s next?
4) get Next and Previous to change stations.
Oh, and it’s all running as an unprivileged user rather than root, which makes me feel warm and fuzzy.
btw, here’s my /etc/lircd.conf:
