Is there a lamp dimmer module I could interface the RasPi with? Preferably UL certified. Google turns up lots of home-brew stuff, but I'd rather not burn my house down.

What about a ultrasonic range sensor mounted on the ceiling? Or use the upside down bottle, but put the float sensor in the bottle.

The Automator posted:The machine has to have a user interface. It has to include a card swiping mechanism, and it has to give the student money. I couldn't think of a better way for it to give out money than to have a couple bills in a tray that has a door in front of it. I mean, if its easy to spit out cash into a tray, I'm all ears, but I think a small sliding door to reveal cash would be easier. You keep saying motion sensor. A beam break sensor or micro switch will be much more reliable. For the door, a solenoid might be easier to use than a motor. Turn on the solenoid, door is open. Turn off the solenoid, door is closed. With a motor, you have to worry about how long to run it for, what position it is in?, or use home sensors.

Mantle posted:How does one access the data on the SD card without being able to boot into Linux? I ran into an issue recently where running an OpenELEC update script corrupted my Linux installation. I wasn't able to boot into Linux again, so the data was irrecoverable and I just reimaged the SD card. Take the card out of the PI and put it into a card reader. You might need to boot your computer with a linux live CD.

Check the server (probably apache) error log.
