Well, the plexiglass case was custom-made by a shop with a laser cutter. As for the hardware: * 7 of these: https://www.gumstix.com/store/product_info.php?products_id=247 https://www.gumstix.com/store/product_info.php?products_id=2... * Each of the Stagecoach boards needs 7 Gumstix boards. Anything in the Overo line should work. * The switch is just an 8-port Netgear. Remove the board from the switch case in order to save space and make for easier mounting. * The power supply is the toughest part. Each Stagecoach board needs a 5V 3.5A power input. I believe they went with a ham radio power supply of some kind. It was fully modular. The stagecoach boards simply stand in little slots cut into the plexi case, so you just unplug the power + ethernet to pull out the board. Once you've done that, it's easy to swap out the individual Gumstix nodes. The switch is just held on under the boards by a couple case screws.
