This is still a work in progress but I have printed and assembled. I created a automatic fish feeder that will use a arduino board that will rotate the auger every 12 hours to feed my fish. I will also have a manual override switch to feed the fish at any time. My old fish feeder was made out of cardboard so I thought it was time to 3D print one.
Added Arduino program for fish feeder. Also new Youtube video on how the feeder works.
Added my source files for editing. You can download them at this link. https://drive.google.com/folderview?id=0B0mS2ccz6lQNQnowYnpEQmZTWkk&usp=sharing
Add Arduino Nano board case to fit the board, transistor, wires and button to look cleaner than having all the wires and board exposed. Added file and picture to project. I just hot glued the board to the hopper case. Working on a way to fasten without hot glue for next update.
Printed out in ABS. The servo motor I used was from HobbyKing. http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=16269 It was a 38 gram servo motor.
For the lid I used a piece of PLA filament and rolled it out straight on the heated bed on my printer and used that as my pin for the hinge. I melted the ends so it is locked in.
Took out the circuit board in the servo and soldered wires directly to motor to make the servo a dc motor. Included arduino program to run feeder. Used 5 volt from arduino board and a 3906 transistor to switch on the motor also need a LED and tactile switch for manual feed. Program feeds fish every 12 hrs on a timer.
