Good guide on selecting motors (basics)
Another nice write-up I stumbled on with Adafruit on selecting a motor. Its a multi-page one, but worth reading. https://learn.adafruit.com/adafruit-motor-selection-guide

Another look at the automated hacksaw
Looks like this is version 2. Its on my list to build (bandsaws for metal are expensive). He even has a BOM listing.

Another beer caddy. But easier to make with handtools

FullPageOS, for RPi
Interesting OS, its goal is an OS for providing information displays. It turns off all screen savers, and other functionality so that its always “up”. Could be good for a photo displayer or one of the mirror setups. http://lifehacker.com/fullpageos-automatically-boots-your-raspberry-pi-into-a-1779862376
