Larry, no patent, however, I did post a complete set of instructions on how to build this on the PSR Tutorial site.

Diki, my keyboard is very stable, and the laptop/netbook is held in place with industrial strength Velcro. Additionally, there is room for a plastic beer pitcher, which I used for a tip jar. (Loved watching that beer pitcher get filled with greenbacks!)

I built about a dozen of these for some of my internet friends on music forums, and with few exceptions, they are all still in use today, more than 10 years since I constructed them. The cost of materials was about $60 and I purchased the aluminum from a local welding shop, where I had them bend it into the shape I wanted. The Lexan for the front of the sign, and the top of the console, was purchased at Home Depot, cut to fit, then held in place with 1/4-inch pop-rivets. I painted the aluminum flat black using Krylon High Temperature spray paint. It does not chip very readily and held up well through thousands of gigs.

My foot pedals were also held in place inside using Velcro during transportation, thereby almost eliminating my possibles bag where they were previously contained along with mics and spare cables. I don't think I opened that bag for nearly a decade other than to get the mic out.

Hope this helps,

Gary
