Centre compartment of a console record player that I'm retrofitting. This encloses the amplifier, a computer and a microcontroller.
The computer, at left on the vertical board, is a Via Epia M10000, lower power mainboard running Ubuntu server. This computer plays mp3's etc and is accessed through VLC's web interface or ssh. I replaced the CPU fan with a nearly silent one.
The microcontroller, temporarily sitting on a cardboard box on the amp is charge of receiving the remote control commands and forwarding them to the appropriate device and also for controlling digital potentiometers in the preamp/mixer. I am currently using an arduino to prototype.
You can also see the massive vibration isolating shelf that the turntable sits on (unstained wood).
