Auto-Feeder (In Progress)

    To keep a consistent feeding schedule for the fish I have attached an auger to a servo motor to provide the rotational energy needed to push out food in a tube. The tube apparatus would be PVC for simplicity and allow for food to exit in both the front and the back (because a servo does not rotate completely around). After that a hopper would be made out of a 2L bottle, or a 20oz bottle filled with fish food pellets. Turns out that the inner diameter of a 0.75'' PVC fitting fits the threaded part of a bottle very well so add some glue to the connection and it would work a very solid joint.

    As seen above I drilled a hole into one side of the auger and then attached it to a servo with some epoxy. Here is a couple videos of it running:

    Unfortunately I haven't been able to finish off these project because I need the help of some real power tools and time to use those tools. This semester has kept me busy between work and school I really don't have time. But once I get some time I'll wrap this project quickly, just need to figure out a way to mount everything. 

    A side-goal was to have a webcam set to record once the food was released into the tank. I'm sure the goldfish would get used to the sound of the motor so that if the camera turned on right when the food was released I could watch the fish eat which isn't really necessary in any way but I thought that it would be cool. One camera underwater and one above, probably in a case like the one I used for the Greenhouse Cameras.
