1) 3D print and post-process the mechanical enclosure

2) apply brush on coating for all 3D printed parts (optional)

3) push in the skateboard bearing in to the back of the wheel.

4) Epoxy 2 magnets in to the magnet holders with their polarity in the opposite directions (Note: it doesn't matter what direction each magnet is facing as long as their polarity is in opposite directions).

5) Epoxy 4 suction cups to the back of mount

5)  Clip away stack-able headers on the bottom of the photon battery shield

6) Solder the following wires:

PIR Digital out --> Photon Digital Pin 4

PIR Power --> Photon 3V3 Pin

PIR Ground-->  Photon Ground Pin

Hall-Effect Signal (Green) --> Photon Digital Pin 2

Hall-Effect Power (Red) --> Photon Digital Pin 5

Hall-Effect GND (Black)  --> Photon Digital Pin 3

7) Connect all jumper wires to the appropriate PIR header pins

8) Secure PIR sensors using 4 #2X1/4" screws

9) Secure Hall-Effect sensor to the mechanical enclosure using 2 "Nylon Slotted Flat Head Screws" and "Low-Strength Steel Hex Nut"

Connect the photon shield to a 3.7V battery

Provision the Photon with your internet credentials and create an app for tracking data. (Instructions here)

Upload this code to your Particle photon.

Place electronics in to the wheel mount

Attach wheel mount to the wheel (using the bearing).
