Introduction: Cheap and Simple Arduino Eggbot
In this Instructables I want to show how to make a simple and cheap arduino plotter that can draw on eggs or other spherical objects. In addition, soon Easter and this homemade will be very handy
Step 1: Materials
List of materials:
-2х Stepper motor (28BYJ-48)
-2x Stepper motor control boards (ULN2003)
-Power supply for 12V +
- Plywood (7.5 mm)
-Тires from a toy car
And various tools
Step 2: Case
To begin with, we'll build the case. First of all, you need to cut out billets from the plywood with dimensions: 120x90 and 120x80 and two more blanks with dimensions: 90x70. Then with a 10mm drill, make a hole like in the photo and still need to make a hole for the bearing and insert it there. After that, everything needs to be glued together. After drying, it is necessary to fasten in the indicated places of the stepper motor
Step 3: Mounts for Eggs
Mounts for eggs made with: tires from a toy car, circles of PVC plastic, nuts, washers, bolts and a handle from the handle that perfectly adjusts to the motor shaft. After gluing all the way as in the photo you need to insert a bolt into the bearing and fix it there with the help of a nut. Bolt one more nut (it is used as a lock nut) and then screw one part of our holder. On the engine, wear our other piece with the cap from the pen
Step 4: The Pen Holder and the Second Axis
The handle holder and the second axis I made of PVC plastic. To connect this axis with the stepper motor, I also used a cap from the handle. The servo is screwed to this part as in the photo.
Step 5: Circuits and Software
In detail about the installation of the software you will learn in the video on the 11th minute
Step 6: The End
That's it. Now you need to fix the egg in our plotter and start creating. Good Easter !!!
