Now it's time to bring everything together.
Trim one corner into a semi-circular curve. Cut the opposite corner off at about a 45 degree angle.
These two cuts will allow the cardboard to rotate inside the box without colliding into the floor or walls.
Add a piece of double sided tape to the rounded corner of the cardboard. Trim any excess tape that extends past the cardboard edge.
Now it's time to mount the servo motor inside the box.
Make sure to give the lifting arm enough clearance!
Place the servo inside the box and use a pen to mark exactly where you will place it.
Press it firmly into place. Motor mount complete!
Poke two hole in the top of the box, about an inch away from the front edge.
Feed the two ends of the string or fishing line through these holes and tie them off.
Two simple knots are sufficient to hold Blinka in place.
Check Blinka's placement within the box, ensuring that her tongue doesn't get caught as the box lid closes.
Now you can hook up your Circuit Playground Express, connect to power, and test your snake charming abilities!
