Introduction: Cheap and Simple Arduino Eggbot

About: My name is Alex and I like to do it all with my own hands. I'm fond of arduino and I like to invent different constructions on it.

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:

-Arduino Uno

-2х Stepper motor (28BYJ-48)

-2x Stepper motor control boards (ULN2003)

-Power supply for 12V +

-Servo (sg90)

- Plywood (7.5 mm)

- Bearing

-Bolts

-Nuts

-Тires from a toy car

-PVC plastic

-Pen

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 !!!

    Check whether you have installed the entire library correctly. And why in your sketch instead of the library "VarSpeedServo.h" is declared the library "Servo.h" and in the tabs of skews you do not have the Auger code VarSpeedServo.h (it is in the folder and should open with everyone). Also, you may have an older version of the Arduino IDE and need to install a newer version

    This would have been cool for Easter, I guess there is next year!
