OK, so I've been googling up a storm looking at the options. I think I'm either going to go with a piglow, and use some code folks have already put together. Seems like the three arms can show something like Temp, CPU Load, something else (I can't remember).
But what really looks like it'd be cool is the Displayotron. Seems I could set it up to show the system and ROM running on Retropie. And I figure the backlights could be setup to have a color that'd match the system (like Red for Nintendo or something). And then use the bargraph to show CPU load. But what I'd love to do is use the joystic on the Displayotron as a safe shutdown button. Could I do that? Does it sound at all reasonable?
