Overview

Feather M4 & PropMaker

Build a Time Baton inspired prop from the Disney+ series Loki. Use a Feather M4 and PropMaker FeatherWing with CircuitPython to make a motion activated prop with lights and sounds!

Different sounds are triggered depending on threshold and the LED changes brightness and color!

Accessible USB

Hidden inside the handle are the electronics. The Feather and PropMaker are fitted in a holder that can easily pull out for easy USB access.

3D Printed Prop

The diffuser is removable much like a lightbulb, you can unscrew it from the assembly.

Parts are designed for support-free 3D printing and fit on beds of most 3D printers!

Time Stick

Capable of altering the flow of time, this weapon is wielded by the Time Variance Authority. This SciFi inspired baton has the power to prune individuals by incapacitating variants. It features seven light tubes arranged in a circular group.

Circuit Diagram

The diagram below provides a visual reference for wiring of the components. This diagram was created using the software package Fritzing.

Adafruit Library for Fritzing

Use Adafruit's Fritzing parts library to create circuit diagrams for your projects. Download the library or just grab individual parts. Get the library and parts from GitHub - Adafruit Fritzing Parts.

Wired Connections

The Prop-Maker FeatherWing is fitted on top of Adafruit Feather M4 Express via female/male headers. The speaker is connected via a molex pico blade connector.

Powering

The Adafruit Feather M4 Express can be powered via USB or JST using a 3.7v lipo battery. In this project, a 2200mAh lipo battery is used. The lipo battery is rechargeable via the USB port on the Adafruit Feather. The slide switch is wired to the enable and ground pins on the Prop-Maker FeatherWing.

3W RGB LED

red pin (R-) to red pin on Prop-Maker FeatherWing
green pin (G-) to green pin on Prop-Maker FeatherWing
blue pin (B-) to blue pin on Prop-Maker FeatherWing
voltage pin (V+) to V+ pin on Prop-Maker FeatherWing

Speaker

Voltage and ground to Prop-Maker speaker port

Slide Switch

Middle pin to enable pin on Prop-Maker
Far left or right pin to ground on Prop-Maker

Note the RGB LED can get H-O-T HOT! Be careful to not touch it or allow flammable materials around it if it is very hot. This is how these parts are designed, to be so bright, and it is not a part design issue.

3D Printing

Fusion 360 Tutorial

In this tutorial I chat about my design for housing the PropMaker FeatherWing and Feather M4 Express in this prop inspired by the TVA Time stick from the Disney+ show Loki. I really like using threads to make this type of assemblies easy to take apart and put back together. By making the pommel removable from the handle, the USB port from the microcontroller becomes easily accessible. I managed to design the PCB holder so it doesn’t require any supports when 3D printing.

CAD Parts List

STL files for 3D printing are oriented to print "as-is" on FDM style machines. Parts are designed to 3D print without any support material. Original design source may be downloaded using the links below:

TVA_Baton_Drawing.pdf

Build Volume

The parts require a 3D printer with a minimum build volume.

150mm (X) x 150mm (Y) x 140mm (Z)

Slicing Parts

No supports are required. Slice with setting for PLA material.

The parts were sliced using CURA using the slice settings below.

PLA filament 220c extruder
0.2 layer height
10% gyroid infill
60mm/s print speed
60c heated bed

Printing Diffusers

The 7x diffuser tubes are printed using clear translucent PLA filament. Use 0% infill to make the model hollow. Using a brim can help with good bed adhesion. Printing a single diffuser at a time is suggested for best print quality.

Design Source Files

The project assembly was designed in Fusion 360. This can be downloaded in different formats like STEP, STL and more. Electronic components like Adafruit's board, displays, connectors and more can be downloaded from the Adafruit CAD parts GitHub Repo.

CircuitPython on Feather M4 Express

CircuitPython is a derivative of MicroPython designed to simplify experimentation and education on low-cost microcontrollers. It makes it easier than ever to get prototyping by requiring no upfront desktop software downloads. Simply copy and edit files on the CIRCUITPY drive to iterate.

The following instructions will show you how to install CircuitPython. If you've already installed CircuitPython but are looking to update it or reinstall it, the same steps work for that as well!

Set up CircuitPython Quick Start!

Follow this quick step-by-step for super-fast Python power :)

Download the latest version of CircuitPython for this board via CircuitPython.org

Click the link above and download the latest UF2 file.

Download and save it to your desktop (or wherever is handy).

Plug your Feather M4 into your computer using a known-good USB cable.

A lot of people end up using charge-only USB cables and it is very frustrating! So make sure you have a USB cable you know is good for data sync.

Double-click the Reset button next to the USB connector on your board, and you will see the NeoPixel RGB LED turn green. If it turns red, check the USB cable, try another USB port, etc. Note: The little red LED next to the USB connector will pulse red. That's ok!

If double-clicking doesn't work the first time, try again. Sometimes it can take a few tries to get the rhythm right!

You will see a new disk drive appear called FEATHERBOOT.

Drag the adafruit_circuitpython_etc.uf2 file to FEATHERBOOT.

The LED will flash. Then, the FEATHERBOOT drive will disappear and a new disk drive called CIRCUITPY will appear.

That's it, you're done! :)

Upload the Code, Sounds and Libraries to the Feather M4 Express

After downloading the Project Bundle, plug your Feather M4 Express into the computer USB port. You should see a new flash drive appear in the computer's File Explorer or Finder (depending on your operating system) called CIRCUITPY. Unzip the folder and copy the following items to the Feather M4's CIRCUITPY drive.

lib folder
sounds folder
code.py

Your Feather M4 CIRCUITPY drive should look like this after copying the lib folder, sounds folder and code.py file.

Audio Files

The sounds used in this project are from the Motion Pulse BlackBox pack from VideoCopilot. The pack contains various sounds that are already in the supported audio format.

Adafruit CircuitPython supports 16-bit, Mono, 22.050kHz .wav audio format. See this guide to help format any audio files you might want to use in this project besides the files provided.

In the main loop, the swing and hit modes randomly choose from a list of sounds. For example, swing1.wav, swing2.wav, swing3, etc. This makes the motion effects feel much more varied and sounds less repetitive.

Power on – on.wav
Idle looping noise – idle.wav
Swing whoosh – swing.wav
Crash strike – hit.wav
