Watson Heirloom
March 15, 2024
A project to build a 3D-printed "Telemetry Receiver Module" for the Apex Legends character "Watson".
Table of Contents
Wattson is a character from the video game Apex Legends. This is a project to build a 3D-printed version of her "Telemetry Receiver Module" Heirloom, with functioning electronics (not a real radar, thought).

Parts Info
These are all of the parts that were bought to build this project. There were some odds and ends that I already owned and cannot find a good link for (plugs, wires, etc).
Filament
I used Prusa PETG for all of the filament. The colors used were Orange, White, and Anthracite Grey.

NeoPixels
The four rods on the end are each covered with one 28-pixel strip. The rods are all wired in parallel.

Perma-Proto Board
This board is meant to be used with a Raspberry Pi, but after looking at its size and layout, it proved perfect for mounting the QTPY ESP32-S2, MCP23017, and EEPROM.

QTPY ESP32 S2
The main MCU.

MCP23017
An I2C I/O expander. I likely could have used less inputs for the buttons, but this seemed simpler.

EEPROM (24LC32AT-I/SN)

Haptic Vibrator
Placed in the grip, just under the batteries.

2-Axis Joystick

I2C Rotary Encoder Breakout
In hind-sight, this was more difficult to work with than just a standard rotary encoder. Reading and clearing interrupts over I2C was a lot of unnecessary overhead.

Other
Generic Capacitors, Resistors, BPJ transistors, springs, magnets, screws, LEDs.
3D Models
If you want to print the objects yourself, here are the 3D models in .step format.
Printable Parts
These represent the parts that are printed in PETG.
Non-printable Parts
These represent the electronics and other parts that cannot be printed. These were used to measure/build objects around.
Schematics
The schematics were built with KiCad.
