1 🧘‍♂️ Tools and Preparation

"A beard well lathered is half shaved." 🪒

1.1. Preparation

Prepare a clean desk and some small boxes to unzip the package. Take a picture of the kit contents in case you lost something later.

It’s better to work in a room without carpet or textured mosaic. Little screws and springs can magically hide themselves if dropped onto the ground.

1.2. Tools and accessories



Utility knife

Cut the tabs holding the wooden puzzle pieces

Sanding paper/foam

Remove pointy fibers

Flat and Phillips screwdrivers

For M2 (diameter = 2mm) screws

Computer with Arduino IDE

USB to mini USB cable

Connect the uploader to computer. Not micro USB

2 x 14500 3.7V Li-ion batteries

Don’t mix with regular AA batteries (1.5V)!

The capacity should be around 800mAh.

Wrong charger may cause danger!
