So, would anyone be interrested in a cheap ($15) open source USB control adapter

Keyboard hack is easy enough. Its how I started. If you need only 3 keys, its super easy to solder on that board for three keys.
Keyboards are cheap and plentiful. What jukebox program are you running?

BadMouth:
So far, your best selling point is having one device that can cover a trackball in addition to both players.
That's a pretty common setup and I can see people preferring a single device.
This hobby is a small niche market though and full of cheap people, myself included.
So finding 100 customers up front is a tall order.

Kickstarter would probably be your best bet.

I'm all for more open source solutions in our hobby.
Cool hardware choice, I'm looking at using a launchpad to control the SMD reflow oven I'm building for some new KADE stuff we are working on.
If you ever want to chat about stuff like kickstarter or maybe contributing to the project, drop me a note.

I'm not really looking to turn this into a business, just wondered if anyone else besides me would be interested in a cheap all in one board that includes trackball/spinner support. I didn't like the fact that none of the devices on the market could handle keyboard or gamepad input and trackball/spinners on the same board. The Tiva uC had the hardware QEI support necessary to do this without lag, and nobody else seemed to be using that chip yet for this purpose, so I figured I'd give it a go. Took me a couple of weeks to nail down the firmware, but I don't feel that's too bad for a chip I've never coded for before.... I haven't even maxed out the GPIO pins on the chip yet. There are a few pins that are muxed on the dev board that there just isn't any easy way to access. The custom board would support a few more buttons beyond what the current firmware supports.

Let me draft up a PCB so I can estimate the build cost. The only reason for the 100 count run preference is that's where component price breaks really start to kick in and I don't have the spare funds (not the time and interest in dealing with kickstarter) to do more than a handful at a time at the much higher small quantity component pricing.

I'd be interested in what you come up with, sure! Subscribed.
