fc-enail

This project is inspired by the FC Community and a desire to have a better E-Nail product, with ease of use, advanced features, and wireless connectivity.

Highlights

• Easy temperature adjustments with rotary dial
• Easy on/off of heater both on device and remotely
• Quick temps from mobile screen to go to a temperature with 1-click
• Save/Load profiles (PID settings and coil temperature offset) for different devices (can use auto-tune to generate)
• Run scripts for fancy up-temp procedures and the like
• Full mobile access including:
  • Remotely start, adjust temperatures, and monitor
  • Run scripts
  • Manage/create/edit scripts with the script editor (drag/drop GUI)
  • Manage profiles and launch auto-tune to generate
• Ability to connect device to WiFi network through device UI
• Automatic discovery of device on local networks, but ability to configure if not found or on different subnets

Installing

• install Raspbian
• install NodeJS 14.x
• npm install -g fcenail --unsafe

1. Update d:\config.txt

   start_x=0 enable_uart=1 dtoverlay=disable-bt gpio=15,16,18,22=pu dtoverlay=audremap audio_pwm_mode=2 hdmi_ignore_edid_audio=1

2. Create d:\wpa_supplicant.conf

   ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev update_config=1 country=CA

   network={ ssid="" psk="" }

3. Boot and run raspi-config a. Hostname: fcenail b. Set localization options: America/Toronto, en-US c. Enable SPI, I2C d. Disable serial console, enable serial

4. Install NodeJS

   • Download unnofficial distribution for ARMv6
   • Create folder: /usr/local/lib/nodejs
   • Uncompress to /usr/local/lib/nodejs
   • Create symbolic link to /usr/local/lib/nodejs/current
   • Update profile/path (Add to /etc/profile) NODE_PATH=/usr/local/lib/nodejs/current PATH=$NODE_PATH/bin:$PATH
   • Run visudo and remove "secure_path"
   • Create symbolic links for node, npm, and npx:

     sudo ln -s /usr/local/lib/nodejs/current/bin/node /usr/local/bin/node
     sudo ln -s /usr/local/lib/nodejs/current/bin/npm /usr/local/bin/npm
     sudo ln -s /usr/local/lib/nodejs/current/bin/npx /usr/local/bin/npx
     

5. Install NetworkManager

   sudo apt-get install network-manager

   Create connections, wifi-wlan0 and Hotspot:

   • /etc/NetworkManager/system-connections/wifi-wlan0.nmconnection

     [connection]
     id=wifi-wlan0
     uuid=ccaac89e-a2db-4412-ba51-b551d75712f0
     type=wifi
     autoconnect-priority=100
     autoconnect-retries=3
     interface-name=wlan0
     permissions=
     timestamp=1608730297
     
     [wifi]
     mac-address-blacklist=
     mode=infrastructure
     seen-bssids=74:83:C2:3A:E3:AA;74:83:C2:2D:62:6E;
     ssid=Linamar
     
     [wifi-security]
     key-mgmt=wpa-psk
     psk=L1n@m@r+23
     
     [ipv4]
     dns-search=
     method=auto
     
     [ipv6]
     addr-gen-mode=stable-privacy
     dns-search=
     method=ignore
     

   • /etc/NetworkManager/system-connections/Hotspot.nmconnection

     [connection]
     id=Hotspot
     uuid=9be42a41-2c0a-42f4-a646-c9bd3b380874
     type=wifi
     autoconnect-priority=1
     interface-name=wlan0
     permissions=
     timestamp=1608320053
     
     [wifi]
     mac-address-blacklist=
     mode=ap
     seen-bssids=B8:27:EB:24:83:71;
     ssid=fcenail
     
     [wifi-security]
     key-mgmt=wpa-psk
     psk=1234567890
     
     [ipv4]
     address1=10.20.30.1/24
     dns-search=
     method=shared
     
     [ipv6]
     addr-gen-mode=stable-privacy
     dns-search=
     method=ignore
     

   sudo nmcli c add type wifi con-name wifi-wlan0 ifname wlan0 ssid <ssid> wifi-sec.key-mgmt wpa-psk wifi-sec.psk <password> 
   

   Edit /etc/NetworkManager/NetworkManager.conf

   [main]
   plugins=ifupdown,keyfile
   dhcp=internal
   
   [ifupdown]
   managed=true
   ````
   
   Reboot and add hotspot
   
   nmcli c add type wifi ifname wlan0 con-name Hotspot autoconnect no ssid hotspot-ssid
       
   set priorities to 100 and 1 for wifi-wlan0 and Hotspot respectively.
   eg. sudo nmcli c mod wifi-wlan0 device.autoconnect-priority 100
