Can do.
No online store, each design I do is pretty much custom.
I accept payment via paypal.
I'll send you a PM with e-mail address.
Measured my wife's baby grand, it is indeed 4 feet from edge lower to edge of upper key.
I'll use 4.5-5 feet wire so the box can sit on the edge, or be left to drape over the edge.
Box will have panel mount connectors for power cord & USB mini-B connector.
Got an idea for the boards, think 8 of them with C# thru C on them, about the limit of the lenght I can do with the license I have, and keeps the boards within 160 x 100mm.
You mention Red & Green - please explain more.
How small do you envision for "little micro LEDs"?
