Project Idea: Replacement Sony MiniDisc remote

A project idea to exercise the brain - replace the RM-MC38EL remote control on my Sony MiniDisc recorder with a larger unit.

It would use a larger and easier to read 16x2 LCD and buttons controlled by an Arduino. This will make it more like a component unit and make it easier to use in my workshop than the fiddly little controls it has now.

Sony never made a component HiMD.

The hardest bit will be the plug - either cannibalise a remote or somehow simulate it? Two pins are used to send commands to the MD (different resistance for each command) and the other two for sending data to the remote's display (will need to figure that out!). It does appear easy to acquire Sony RM-MZ3R remotes on eBay, giving me access to a source of the plugs. It would be nice to have just the four-pin plug, leaving the headphone socket free.

I did find a similar project that pre-dates Arduino. In this case it was to allow the use of infra-red remote controls.

Might turn out to be another dead-end ... but it is fun to experiment!
