Find Cheap Gas with Google Maps

Mashing up Google maps and Gasbuddy = locations of cheap gas in your area on a Google map (map or satellite view). Just choose a city- then the data on the right side is updated cheapest gas prices. If you have mobile high speed access you could add a GPS and have this running while you drive. In the future, maybe our cars will do this for us. Via Robotwisdom. Link.
This project consists of retrofitting a vacuum cleaner to fire a projectile through the usage of air pressure (or lack thereof). The parts: Vacuum cleaner, obtained from a garage sale, 12″ wooden dowel, 10 feet PVC pipe, and Tee fitting for the pipe. I’ve seen bigger versions of these do some amazing things like send a ping pong ball through metal cans.
Great use for that old drive! MuCoP allows you to play your favourite music CDs on an “old” PC CDROM drive, instead of throwing it away. It consists of the bare essentials: a PIC microcontroller (16F877), 6 push-buttons, stereo audio amplifier (TDA2822M) and a few discrete components, not forgetting the IDE CDROM drive.
