@drwho and very yes on your concept - @jjg has a similar project underway, @iliana has a project for racking pis, and everybody's looking over that risc-v event horizon ;)
Related: I inched (millimetered?) closer to getting my chassis modules dialed-in over the weekend. Got some printer time and laser cutter lessons at a nearby hackerspace.
I've also secured the funds needed to procure the remaining components, so I may have a #raiden Mark II prototype running before the end of Q1 2018.
