Interest in all in one button interface and LED controller?

[engg100]

I have been looking at button interfaces and LED controllers trying to decide what to use for a two player setup. I want to have RGB lit buttons and joysticks. I would have 2 joysticks plus ~20 buttons (22 RGB LEDs = 66 LED outputs). This would mean I would need a joystick/button interface (~$40) and at least two LED-Wiz (32 port) ($45x2 = $90) LED controllers. That would cost $130 just for controllers and consume 3 USB ports.

I am an electronic engineer and was thinking of designing my own all in one board which would scan 20 buttons plus 2 joysticks and be able to drive the 22 RBG LEDs (PWM each color of course). I would be able to build the boards for ~$80-$90 each (a savings of ~$40-$50, and they would only use ONE USB port and take up MUCH less space! One board as opposed to 3!)

If I were to design this board would there be any interest in anyone else purchasing one? Also, what other features would you like to see in its design?

32 inputs, yours proposed would have 28. make it have a shift feature or shazam for admin stuff. everything else sounds good

Take a closer look at the popular encoders (iPac, GP Wiz) the LED modules (from both the same companies) and improve on them. A combined and improved board would certainly sell like hot cakes, especially if you keep the prices LOW and you ramp up the inputs. And like Lanman (above) says, a shift function would make it even more popular.
