Comment Sheevaplug + usb cdrom (Score 1) 258

I use a sheevaplug with a usb cd-rom drive to close the air hatch on my wood burning central heating system. Of course it also has some fishing line and duct tape. The idea is that i can close the hatch with a timer or remotely at will. I've built a website for this purpose. I have two raspberry pis working as cameras for the system. If I leave the hatch open the air getting through the system will cool down the system much faster. I just eject the empty drive and the fishing line gets "longer" and closes the hatch.

The trouble with doing something right the first time is that nobody appreciates how difficult it was.
