Spooky Eye in action

Written by tommyho510@gmail.comVersion 1.0 (October 2019)

simple script to proof the idea and work

Project media:

spooky eye in a foam pumpkin

How-to:

Prepare M5Stick-C (1), pumpkin (1), 1" clear acrylic half sphere lens (1, available at Tap Plastic), carving knifes (2, long and short ), Scott tape, fine black Sharpe marker.

Program the M5Stick-C for UIFlow. Connect to the stick and upload all photos.

Program the M5Stick-C with the M5-spooky-eye.py

Use the fine marker to outline the cut hole for M5Stick-C

mark the hole

Use the carving knifes to cut thee hole for 2" deep

carve the hole

Extract the foam or pumpkin flesh.

Use the marker to mark the center of circle 1.25" from bottom and use the acrylic lens to mark the eye hole.

Use the carving knifes to cut the hole. Make sure to cut the hole 1/8" smaller so the foam or flesh can hold the lens.

Insert the lens. Insert and use your finger to adjust the lens via the stick hole

Use a Scott tape to make a puller for the M5Stick-C. This will allow you to pull and extract the M5Stick-C from the pumpkin. You can also use tape and marker to darken the edges of the screen,

Turn on and insert the M5Stick-C into the pumpkin.

Enjoy the show!

To extract the M5Stick-C, pull the tape.

Coming Soon:

Add speaker
IMU function to control eye movement
Allow to change eye by shaking the pumpkin
Layers of eye iris, pupil, lip to simplify the images
Use mic to wake eye
