Interesting recycling of this box.

 I've never seen a contrast / brightness, etc. control panel like this, and it gives me an idea for my thelightherder.com project. Controls like this would allow for being able to see at a glance the state of the different parameters, unlike the control knobs, which spin forever. I don't know if something like this exists for HD monitors - maybe something that could be created?

Hi Dave, thanks! What a great machine you build. Nice woodworking too!

I am not an expert here but my assessment is, that since the controls on the panel don't have a range but turn endlessly, they are probably rotary encoders and don't know about their position but can only send increase or decrease signals.

I guess you could use a microcontroller and some variable slide resistors to send GPI signals via the GPI connector but you wouldn't have feedback on the controls.

Thanks!
