Step 1: What you'll need...
-3 wall outlet sockets (about a buck each)
-1 normal power strip ($10)
- 6 3A 120VAC relays (at DigiKey here $1.8 each)
NOTE: 3A at 120VAC is 360 Watts per socket. If you are interested in remotely controlling a microwave or hair-dryer think about investing a few extra bucks in bigger relays.
- 1 SIS-7C chip from the nice people at Simerec ($19.95)
- 1 IR receiver from Simerec. ($2.99)
- 1 universal remote. I used this one (2$)
- Solid 18AWG hookup wire.
- Any kind of small AWG signal wire.
- 12 ft of insulated wrapping wire.
- Some sort of housing big enough to fit all your stuff. I used a generic Radio Shack one.
- 1 120VAC to DC 5-6 volt converter that outputs at least 400mA.
- if you are adventurous you can build your own power supply! See step 4 for parts and schematic.
My total: $40-50 depending on what you can scrounge.
- Soldering iron and solder
- Protective eye wear!
- Wire cutter/stripper
- Electric tape
Optional but HIGHLY recommended:
- "Third hand" to help with soldering
- Some sort of digital logic board or similar proto-board/breadboard
