Just finished my power strip and wanted to share. I'm very happy with the results. Special thanks to tastydog in this thread.
First, the parts list:
1 x Relay Board - Found here. This is an 8 port SSR relay board that can handle up to 6 amps per channel. It is also Opto-isolated and supports pwm (you'll see why this matters later).
8 x NEMA 5-15R 15AMP 125v 2-Pole 3-Wire Grounded Receptacles http://parts.digikey.com/1/parts/993...-208697-2.html
8 x SWITCH ROCKER SPDT 10A 125V - SRB24A2HBBNN http://parts.digikey.com/1/parts/970958-switch-rocker-spdt-10a-125v-srb24a2hbbnn.html. 3 position gives me the ability to override each outlet individually (I'll explain later)
2 x terminal blocks (found at lowes)
2 x solderable serial port
1 x serial cable
lots of 14AWG wire (black, white, green)
a little 22AWG wire (red,black)
And finally I needed an enclosure. Ideally, I would have liked to used something like this, however, at $100 a pop this was not realistic. I wound up gutting an old 100Mb/s switch I had in the closet. I used a grinder to cut out the original face plate and replaced it with some 16AWG sheet metal and held it together with some epoxy. If I happened to have a spot welder I would have used that and gotten a cleaner face.
On to some pictures:
Full album here.
The 100Mb/s switch before I gutted it.
The back:
The inside:
The relay board hooked up to my arduino, controlling a single outlet
Cut the faceplate and a new piece of sheet metal to replace it:
New faceplate is epoxy'd in and I've marked where I will cut for the outlets. Also, you can see I've epoxy'd down the terminal bars. One for ground and one for Hot, which has a piece of plexiglass separating it from the chassis:
All the outlets are in!
I made similar cuts to get the switches in place and started wiring everything up. Because of spacing I had to have some wires closer to the heat sink than I would have liked. I am keeping an eye on the heat to make sure it isn't an issue.
