• Store up to 12 banks of 12 clips via web interface

• create alias for running python scripts with sudo and passing env variables to the virtual env
  • `alias supy='sudo -E env PATH=$PATH python3
• added this line to /boot/config.txt
  • dtoverlay=gpio-shutdown,gpio_pin=21
• create/enable system services to start web-app and clip player so they start on boot
• create .env file at repo root
• reboot pi, web app should be at http:https://clippi.local:5000/ once that's complete

player.service (the actual clip looper):

[Unit]
Description=clippi.player

[Service]
User=calvin
ExecStart=sudo -E env PATH=$PATH /home/calvin/env/bin/python3 /home/calvin/App/app.py
StartLimitIntervalSec=8
StartLimitBurst=1
Restart=always

[Install]
WantedBy=multi-user.target

app.service (the web-app):

[Unit]
Description=clippi

[Service]
ExecStart=/home/calvin/env/bin/python3 /home/calvin/App/web/RaspWebInterface.py
Restart=always

[Install]
WantedBy=default.target

I more/less followed instructions here to set up the system services

the content in the .env file you created should look like this:

WEB_APP_SECRET_KEY=your_secret_key
BANK_COUNT=number
BANK_SIZE=number
APP_PATH=path_to_root_of_application
BANKS_PATH=path_to_banks

for my working prototype the values (outside of the secret, lol) are:

BANK_COUNT=12
BANK_SIZE=12
APP_PATH='/home/calvin/App'
BANKS_PATH='/home/calvin/App/__CONTENT'

theoretically they should be able to be defined as whatever but the .gitignore importantly include the __CONTENT directory that is my BANKS_PATH. An important but unenforced coupling so just make sure whatever you use as your BANKS_PATH is in your .gitignore consoleblank=1 vt.global_cursor_default=0 was appended to /boot/cmdline.txt to remove boot splash image and console/cursor
