I now have another group interested in the evolution of the Kestrel Computer Project.  In particular, I collaborate on the design and construction of various fursuit/cosplay ideas, and my Kestrel project has come to light there.  We have been having some issues with the Teensie board we've been using in the past (not enough I/Os), and with Raspberry Pis (too slow I/O; the AXI -> AHB/APB bridge is just too costly to keep up sometimes; also, not enough I/Os), and so now they're interested in the possibility of using FPGAs programmed with a KCP53000 or KCP53000B processor for their embedded development needs.

Cool!
