So, i decided to make a simple DIY pencil sharpener with very few components that can be arranged easily.

Step 4: Let's Get Started
- Using Hot Glue, paste a manual sharpener inside a bottle cap such that the sharpener hole is almost at centre of the cap.
- Fill Hot Glue inside to make the bond very strong but make sure to leave the blade uncovered.
- Attach the bottle cap to the servo motor accessory as shown in the images above.
- Cut a plastic bottle into half.
- Mark and cut a cavity of the size of servo motor at the lower part of the plastic bottle.
- Insert the Servo motor in the cavity and secure it with Hot glue.
Step 5: Make Electrical Connections
- Cut a piece of cardboard that can cover the bottle opening.
- Using Hot glue, paste a toggle switch on the cardboard.
- Connect a battery connector clip to the motor terminals and the toggle switch, such that switch can be used to control the operation of motor.
- Using a Stationary knife, cut the lower base of the bottle which will be then used to collect the waste. (Note: Make sure to refer the video to get more clarity about the procedure.)
- Using Hot soldering iron, make a hole at the side of the bottle such that it coincides with the sharpener hole.
Step 6: Test the Electric Sharpener
Connect a 9v battery to the connector clips and our simple homemade Electric Pencil Sharpener is now ready.
