Automatic Fish Feeder with micro servo control V2

This thing is based on the model made by Cory Oberdas (http://www.thingiverse.com/thing:301532). Thank you Coberdas for sharing the sources

I have made some modifications as follows:

The hopper now attaches to a sera food container;
I´ve made a cap fot the auger tube, so i think it will mantain the food dry;
The servo is now a Micro 9gr servo from hobbyking (http://www.hobbyking.com/hobbyking/store/__38024__HXT900_9g_1_6kg_12sec_Micro_Servo_UK_Warehouse_.html)

The yellow can if from a tetra fish food (http://www.tetra-fish.com/Products/aquarium-fish-food/best-tropical-fish-food/tetramin-tropical-fish-food-flakes.aspx)

V2 Update: Added gears on the auger to allow use of a kind of mixer to force the feed down when using flakes food. Use a long threaded screw with nuts and bolts to fix them as shown in picture.
