Twitter Remote Control
Control Lights with Twitter from Justin Wickett on Vimeo.
I can't tell you in great detail how exactly this works, but here's what I got from the video:
1. Twitter account
2. Cell phone
3. Texting capabilities
4. You need a INSTEON switch
6. Cable leading from computer to wall outlet that communicates to the switch.
Often I feel other ideas come from learning new technologies. So even if this doesn't seem completely necessary I could imagine other uses for something like this. Like if you forgot to turn your lights off, now you can. Or for secuirity reasons you could have turn them on from anywhere.
