Automatic feeding machine



An automatic feeding machine and surveillance system for a guinea pig.

You're going away for the weekend, and your guinea pig is left at home. Who are supposed to feed it? A "normal" person would probably just ask the neighbour to do it, but a budding engineer would of course do something unnecessarily complicated in a situation like this. The solution was an automatic feeding machine which can be remotely controlled. A spindle with six chambers made out of cardboard, rotated with an RC-servo certainly did the job. The servo was simply controlled with a Basic Stamp 2 connected to a serial port, and the servo position was changed by logging on the computer using remote desktop and starting a serial terminal program. A web camera was also installed, and was easily streamed with the integrated streaming server in VLC media player.
