Off the top of my head I break it down like this:
--Locate the (or the best) "found" box
--Hyperdyne for the electronics
--RussRep for the pistons
--Remainder of the guts would be fairly easy to knock out in pretty much anyone's workshop
That would really nice on my shelf. I don't have a clue where to begin as far as making one though. Someone here could I'm sure. The digital area would be tough to replicate I think. Anyone willing to try?
