I made a box that includes elements that you can touch, which leads to shell opening. I wanted to create something that gives the sense of accomplishment, especially for children.

Lasercut the plates. Remember to have space removed from the plate, to add the wires and electronics. The big box: 340x110. The small plates on top: 220x40.

Soldering and Neopixels

Add the neopixels, but here you might have to solder the wires together, to make the pixels connect.

Servo and Shell
