# Lucio Blaster 2020 - CircuitPython for Advanced Prop Making
## Overview
https://www.youtube.com/watch?v=Bg6SUQ9hZ2c
It's time for a modernized prop blaster! This guide is an overhaul of the Lucio Blaster project from 2017 (The original was a three part guide [here](https://learn.adafruit.com/overwatch-lucio-gun-pt1/overview), [here](https://learn.adafruit.com/overwatch-lucio-gun-pt-2/blaster-circuit-integration?view=all), and [here](https://learn.adafruit.com/overwatch-prop-gun-lucios-blaster-pt-3).) You can also use this as a leaping off point for any prop or cosplay element that requires lights, music, and triggered sound effects.
A lot has changed in three years, and the project has been greatly simplified, thanks to advances in hardware and software! We'll now use the Feather M4 Express running CircuitPython and a Prop-Maker FeatherWing.
Thanks to dual-stream, native .mp3 playback in CircuitPython, we can eliminate the need for multiple pieces of hardware previously required to play music and sound effects at the same time, and the power, amplification, and NeoPixel driving circuits have been similarly simplified.
And speaking of NeoPixels -- the LED animation library makes it astonishingly simpler to create highly awesome lighting effects!
This guide shows how to connect all the electronics you need to make your own Sonic Amplifier, or modify them to any prop need.
A future update will show all of the guts fit into a new 808-themed 3D printed blaster! Download the [model files here](https://www.thingiverse.com/thing:2034258) to make your own.
Here's some demo video of the original version to get a feel for the project:

# Lucio Blaster 2020 - CircuitPython for Advanced Prop Making
## Build the Blaster Circuit
We'll build out the circuit starting with the NeoPixels. These will plug into the JST port on the Propmaker FeatherWing which can drive them with more power than a bare microcontroller on its own.
A pair of toggle switches will connect the Propmaker for powering the project on and off via the Enable pin, and for switching song/color modes.
To drive the four speakers we'll connect one to the amp built into the Propmaker and then add three 2.5W class D amps for the remaining speakers.
We'll plug the Feather and Propmaker into a quad FeatherWing kit which gives us plenty of prototyping area to connect the amps and the trigger buttons. Adding Feather terminal headers make it easy to connect the buttons.
Here's a Fritzing diagram of the complete circuit:
## NeoPixels
We'll create a single circuit of all the NeoPixel strands, rings, and jewel so that they share a single data line, ground, and power.
First, solder together the four quarter segments into a single ring. When doing so, be sure to solder all of the power and ground pads, and three of the four Data In/Data Out pairs.
On the un-soldered Data In segment, solder a JST wiring interconnect cable so that the ring can be connected to the rest of the NeoPixels -- this will be the last set of NeoPixels so it doesn't need an out cable.
## And More NeoPixels
Solder a pair of in/out interconnect cables to each ring, jewel, and strand so they may all be joined.
It's important to be consistent with polarity of interconnects so all of the Data In sides can only be connected with Data Out sides.
## Connect the Strands
I decided to wire the two VU meter strips directly to each other, and use the interconnects at either end for connecting to the Propmaker FeatherWing and the rest of the circuit.
Plug them all together and they're ready for use!
Primary:
## Quad Board
Solder female headers into the top two positions of the Quad board.
Solder male headers to the underside of the Feather and the Propmaker so they can be attached to the Quad.
Then, solder the terminal blocks to the bottom quad area.
## Add Amps
Use three sections of male header pin rows to solder the three amps to the prototyping area as shown, pushing the long ends of the pins down into the board so they can be used as posts for soldering the wires.
We'll wire the circuit connections as they're shown in the Frizing diagram, except we'll do it underneath the board.
Solder a set of wires from the Quad board GND to the GND posts of the two bottom amps as shown in the first wiring picture here.
This is followed by running a circuit from the +V rail to the appropriate posts.
Then, run the A0 pin to the A+ (audio in) pin on both bottom amps and the A1 pin to the A+ of the top amp.
## Connect Speakers & Switches
Connect two of the small speakers and the large front speaker to their respective amps as shown using the terminal blocks.
The third small speaker will connect to the speaker output on the Propmaker. Do this by grafting in a [Molex "Pico-Blade" connector](https://www.adafruit.com/product/3922).
You'll use the Feather terminal headers to connect the trigger buttons to ground, A5 and A6.
The toggle switches are connected to the **En** & **GND** pins on the Propmaker wing and the **SW** & **GND** pins, also on the Propmaker. You can solder these directly or add a couple of 0.1" terminal blocks first.
## NeoPixels, USB, & Battery Power
You can now plug in the LiPoly battery as well as the USB panel mount to extend the Feather's USB port to make it accessible from the exterior of the prop. The USB will be used both for programming the Feather as well as charging the battery.
Plug the NeoPixel mega strand into the JST socket on the Propmaker FeatherWing and the blaster is ready to go!
# Lucio Blaster 2020 - CircuitPython for Advanced Prop Making
## CircuitPython on Feather M4 Express
[CircuitPython](https://github.com/adafruit/circuitpython) is a derivative of [MicroPython](https://micropython.org) 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](https://circuitpython.org/board/feather_m4_express/)
**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! :)
## Further Information
For more detailed info on installing CircuitPython, check out [Installing CircuitPython](https://learn.adafruit.com/welcome-to-circuitpython/installing-circuitpython).
# Lucio Blaster 2020 - CircuitPython for Advanced Prop Making
## Code the Blaster
## Text Editor
Adafruit recommends using the Mu editor for using your CircuitPython code with the Feather boards. You can get more info in [this guide](https://learn.adafruit.com/welcome-to-circuitpython/installing-mu-editor).
Alternatively, you can use any text editor that saves files.
## Installing Project Code
To use with CircuitPython, you need to first install a few libraries, into the lib folder on your **CIRCUITPY** drive. Then you need to update **code.py** with the example script.
Thankfully, we can do this in one go. In the example below, click the **Download Project Bundle** button below to download the necessary libraries and the **code.py** file in a zip file. Extract the contents of the zip file, open the directory **Lucio\_Blaster\_2020/** and then click on the directory that matches the version of CircuitPython you're using and copy the contents of that directory to your **CIRCUITPY** drive.
Your **CIRCUITPY** drive should now look similar to the following image:
https://github.com/adafruit/Adafruit_Learning_System_Guides/blob/main/Lucio_Blaster_2020/code.py
## Audio Samples
You can get started by using the Lucio music and sound effects .mp3 files. (Of course, you're free to use any files that you like, see below for more info on that.)
Download the .zip file linked below and then uncompress the file. Drag the **/lucio** directory onto the root level of your Feather's **CIRCUITPY** drive.
[lucio.zip](https://cdn-learn.adafruit.com/assets/assets/000/092/934/original/lucio.zip?1594179939)
## Make Your Own
To make your own .mp3, use audio software such as [Audacity](https://manual.audacityteam.org/man/mp3_export_options.html) to save them with these settings:
- bit rate: anywhere from 16 to 320 kb/s (lower will be smaller, higher is better quality)
- sample rate: 22050Hz or 44100Hz are recommended, although 16kHz, 24kHz, and 48kHz should also work
- channels: mono or stereo
- must be DRM free
## What It Does
These are the main features of the code:
- Play one of two background music song files depending on the mode switch position
- Play NeoPixel LED animation to the beat, the base color changed depending on mode switch position
- Trigger button plays shooting sound effect file and flashes all NeoPixels white
- Alt trigger button plays alt shooting sound effect file and flashes all NeoPixels white
- Tilt "up" of the unit (Propmaker FeatherWing's accelerometer) plays reload sound effect
- Tilt "down" of the unit plays "ultimate" sound effect
Look through the code and you'll see places to tweak and modify the behavior. You can use the **led\_animation** library's `PixelSubset` code to send entirely different animation and color to the different logical groupings of pixels, for example.
