Gah, so many different things, but I'm guessing that few of them will be pertinent . If it's with regard to your DT projects, then I'd probably go down the case route (I like a combined stool and stand, but there's little I can think of that would improve on products already out there, so if you decide on that, copy what's available). A robust, yet lightweight case that securely holds your instrument, pedals and bits and bobs is something I'd look at (individual, customisable compartments for the pedals and accessories would be a nice touch). Good luck with your project and don't forget to share some photos when you're done.
