3D model description

This is my open project of big dog feeding system.

Parts involved :

  • 1x PVC T joint element with 48mm inside diameter & 66mm outside diameter.
  • 1x Nema 17 stepper motor.
  • 1x Arduino Uno board
  • 1x RTC time like DS3231, but can use as well DS1307 or others, to keep accurate timing for years to come :), and avoid Arduino rollover of variables for time

  • 1x Stepper Driver. I used UI robot driver model : UIM24002 .. but you can use any other type as long as it is at least 1.6A for the most common Nema17 motor.

  • 1x 3d printed Augere that is attached here, to fit inside the Pvc T joint.

  • 1x 3d printed Pcv lid and Nema 17 motor support.

  • 1x M4 nut & bolt

  • 3x small fixation screw like M3's to fix the holder of motor on the pvc pipe

The program to feed the dog at 3 time intervals is placed in the attached zip.
Movies can be seen as well here :

If inventor drawings are required please request them.. trough messages.. and as well drawings of the complete enclosure..
This is still in work. Currently I'm attaching a servo to steer the food before moving it out as otherwise it would block.. and it really works as you can see in the last clip movie.
