Development Setup

For developing on your own Ubuntu / Debian machine:

$ sudo apt update
$ sudo apt install python3 python3-dev python3-pip python3-virtualenv libopenjp2-7 git
$ git clone https://github.com/KamloopsMakerspace/MakerHub/makerhub.git
$ cd makerhub/
$ virtualenv -p python3 env
$ source env/bin/activate
(env) $ pip install -r requirements.txt
(env) $ python main.py

Rasberry Pi Setup

SD Card

Format SD card, mount on your own system.

$ cd boot/  # on SD card
$ touch ssh
$ touch wpa_supplicant.conf

Edit wpa_supplicant.conf:

country=CA
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
network={
    ssid="YOUR_NETWORK_NAME"
    psk="YOUR_PASSWORD"
    key_mgmt=WPA-PSK
}

Append to config.txt:

enable_uart=1

Optionally set up a cronjob:

$ cd rootfs/  # on SD card
$ sudo touch var/spool/cron/crontabs/pi
$ sudo chmod u=rw,og= var/spool/cron/crontabs/pi
$ sudo chown pi:crontab var/spool/cron/crontabs/pi

Edit var/spool/cron/crontabs/pi (optional):

*/5 * * * *  # example command that runs every 5 minutes

On Raspberry Pi

SSH into the Raspberry Pi for setup:

$ sudo apt update
$ sudo apt install python3 python3-dev python3-pip python3-virtualenv libopenjp2-7 vim byobu git
$ sudo hostnamectl set-hostname makerhub

Replace "raspberrypi" with "makerhub" in /etc/hosts.

Create "makerhub" user:

$ sudo adduser makerhub
$ sudo usermod -aG dialout makerhub
$ sudo usermod -aG lp makerhub
$ sudo usermod -aG gpio makerhub

Edit /lib/systemd/system/[email protected]:

ExecStart=-/sbin/agetty --autologin makerhub 9600 %I mt70

Edit /etc/passwd:

makerhub:x:1001:1001:,,,:/home/makerhub:/home/pi/makerhub/main.py

$ cd
$ chmod o+rx ~
$ git clone https://github.com/KamloopsMakerspace/MakerHub/makerhub.git
$ cd makerhub/
$ sudo tic -o /lib/terminfo/ mt70
$ virtualenv -p python3 env
$ source env/bin/activate
(env) $ pip install -r requirements.txt
(env) $ python main.py

# Make sure it loads, then press D, then X to exit

Restart getty:

$ sudo systemctl daemon-reload
$ sudo systemctl restart [email protected]
