I have a pretty good stash of various parts so I'll be aiming to build the first prototype mostly out of gear on hand. This means it will probably look pretty ugly or be using obsolete transistors or whatever but it will get the job done.

I'll be using a Carambola2 for the Fencepost Station prototype because I have one on hand, and it runs OpenWRT, which will migrate well software-wise if I end up choosing the
WRTnode I am currently considering to drive the whole thing. And so-on.

This should mean that pretty soon there should be a cobbled together system actually running, then it will be time to look at spinning PCBs or making a well-designed enclosure. Perhaps some sponsors reading this might be able to help out at that point ;-)

Also there may be a lead time on some parts but I don't want that holding up prototype development.
