Requirements

• "Totoro Family" 3D Model by PatrickFanart
• Slic3r to single out Totoro and slice the 3D Model
• Raspberry Pi Zero
• Micro SD Card (UHS Speed Class 1 for faster startup, see ./src/install.sh)
• Micro USB Charger with On/Off Switch
• Adafruit I2S 3W Stereo Speaker Bonnet
• 3W Stereo Speaker Set
• MDF Panel (for easier sanding), screws, glue, paint, tactile switches, led, low-voltage-cable, resistors, kapton tape,...
• Variety of tools
• Lots of time and patience 😉

Process

1. Creating the "slices"

2. Sanding it down

3. Preparing the electronics and internals

4. Glueing it all together

5. Painting Totoro

6. Installation and soldering of the electronics

Using external pull-down resistors as they proved more reliable for long time usage.

7. The finished product

Raspberry Pi Setup

# Setup sd with barebone raspbian and create "ssh"-file in boot.
# Boot the rpi and ssh into it.

# Use rapi-config to change keyboard-layout and disable serial.
sudo raspi-config

# Install git
sudo apt-get install -y git

# Generate ssh-keys and add it to this repo
ssh-keygen

# Clone repo
git clone [email protected]:LowieHuyghe/totoromusicbox.git
cd totoromusicplayer

# Run i2samp install. Twice!
./src/install/i2samp.sh

# Run install to optimize startup, and setup the service.
./src/install.sh

# Add your mp3-files to ./music/

Room for improvement

For this project I started off with what I knew and learned a lot along the way. I enjoyed making it and am very happy with the final result.

As with everything, there's always some room for improvement:

• Even with all the optims, startup time is still 20 seconds.
• Running a complete OS is not really necessary.

A solution for both could be the Adafruit Music Maker FeatherWing with Amp controlled by an ESP8266.
