I needed to be able to control an AC outlet with a FEZ board. I mounted a GHI Gadgeteer relay module in the bottom of a deep 4" electrical box on 1/4" standoffs. Since I needed a longer cable to run from the outlet back to my FEZ board I soldered an eight wired cable to an extender module and plugged the extender module into the relay board. All of this fits inside the standard 4" AC outlet box.
The other end is a bit messy at this point as I did not have another extender module so I used a Duinoproto. It was good enough to test that everything works. Well almost everything, the 8 wire cable I used was junk so I’ll have to replace it.
Here is a quick video:
This gave me an idea for a module that I call the Gadgeteer LRE (Long Range Extender). Picture a small module with a DB9 and a Gadgeteer 10-pin header. A DB9 actually has ten connections, the 9 pins and the shield. A decent quality DB9 cable will have 9 wires and the shield so you have all ten connections and can easily move a Gadgetter module several feet away from the processor board.
I’ll get a board laid up by tomorrow and start another thread for it.
