Intro[edit]

Raspi-Mobile is designed to run as a Mobile Device together with your Tablet or Laptop, prepared for conditions such as in a Train, Flight, Hotel and so on.
The project has its focus to run as a Streaming Server next to common features like Wireless and Internet-Routing support.

Two major Raspberry/Linux issues are solved:

  • True automatic mounting of USB flush drives
    • Plugin any USB sticks, supporting the filesystems ntfs, vfat and exfat
  • Graceful shutdown
    • This solves the issue of preventing disk damages in case of losing electricity power.
    • No need to login or connecting a keyboard and monitor to shutdown, just plugin the shutdown usb device to initiate a graceful shutdown

Features[edit]

  • Easy to setup
  • Supporting the Raspberry4. The project was developed on Debian Buster with the kernel version 5.10.17-v7l+
  • Slim image file download, the image size is less than 2GB
  • Automatic mounting and un-mounting USB flash drives
    • Supported file systems: ntfs,ext32 and vfat
  • Graceful shutdown using a special prepared USB flash drive labeled with RASPI-CLEAN-SHUTDOWN
  • Wireless support, the device has a mangement web to customize WiFi settings like SID and password
  • Routing support together with ethernet connectivity, all interfaces are using DHCP
  • Support OpenVPN
  • Support of common protocols for streaming:
    • SMB/CIFS
    • WebDav

Easy Installation[edit]

  • Get the 2GB image here
  • Write the image to a Micro SD Card with the size of equal or better greater than 2GB, there is no limit, use any size of your Micro SD Card
    • To write the Image you may use tools like DiskImager
  • Insert the Micro SD Card to your Raspberry and start it
    • The disk will get automatically expanded to the maximum size during the first boot
      • Optional you may check the disk size by logging in via ssh and then run raspi-config, goto advanced and then expand filesystem, finish and reboot
