Just to outline my actual project (and thank you for your help and patience) I am hoping to make a MUCH simpler version of this:
I like his design, but I need mine to be kid friendly, and easier to modify for various locations.
Instead of MUSIC keyboards, I just want Large Buttons:
Say, 5 buttons to start, and add more later. It would be great if the buttons lit up (not needed in this version), and I could place them as far as 15-20 feet away from the laptop. This is negotiable as well, it could be one wall space with the buttons if need be.
I don't know if that helps with the concept.
