Desk Light that Adjusts Depending on the Angle of the Head

When you're looking up, you want the light to not hit your eyes. You want the light to always shine from over your left shoulder. How hard can this be?

Door Knock Detector and Reporter

Device that you attach to the viewhole. When the door is knocked, the device, if armed, will take a picture through the viewhold and make it available on the internet through upload or email. How hard can this be with linux? Should take a shot at this sometime.

After attending Maker Faire 2009, I have renewed interest in this one. Question is - how does one recognize a knock on the door electronically? My mind came up with a sensor that detects vibration - you decide how soft of a knock you want to detect and build a sensor accordingly - it's this shallow cuboid filled with oil or some other viscous fluid, and in it, you have springloaded wires with weights - speaking microscopically of course - at their ends. Knock - weights move - and complete an electrical circuit and you detect a knock. This is probably a MEMS problem.

Other way is to look at the output of a microphone and use that. But, now you're into preamp/no preamp, etc.

Yogic Abortion

aka psychosomatic abortion. Surprised no one's thought of this before. Once this becomes standard, the politicians will be irrelevant in this sphere. Mind over matter. You'd need real thought police to prevent this.

Damn! Just Deleted this One!

How's that for an idea - have an undo button on blog management.
