temp solution - an error during torrent download - edit sysctl with

Code:
sudo nano /etc/sysctl.conf
and insert following at the end of the file:

Code:
net.core.rmem_max = 4194304
net.core.wmem_max = 1048576

then
Code:
sudo nano 50downloadHDD.sh
and

and replace code with content below:

Code:
#!/bin/sh

# name of torrentfile = name of directory in torrent
torrent="raspiblitz-hdd-2018-07-16"
# size of a valid download (run on seed directory 'du -s ./[TORRENTDIRECTORY]')

    # HDD has already content
    echo "It seems that HDD has already content. Try to continue with ./finishHDD.sh"

        downloadsize=0
      fi
      # add some tolerance for checking

      #
      ./00mainMenu.sh
      exit 1;
    fi
    echo ""

    echo "*** Moving Files ***"
    echo "moving files ..."
    sudo mv /mnt/hdd/$torrent /mnt/hdd/bitcoin
    echo ""

    # set SetupState
    echo "50" > /home/admin/.setup

    # continue setup
    ./60finishHDD.sh

  fi
else
  # HDD is not available yet
  echo "*** Mount HDD on /mnt/hdd first ***"
fi

fix permissions if needed:

Code:
sudo chmod +x 50downloadHDD.sh

then reboot and init the blockchain drive

Raspberry Pi 3 B+ is recommended for this setup. Have you managed to set it up? I would like to know more details such as RAM and CPU usage. I don't intend to run anything else on the Raspberry Pi; however, it would be nice to be able to use it like a normal computer without any problems. I was thinking of trying this out, but I am afraid that it might be a bit overkill for me. I would be glad if you could answer my questions.

With so low cost, only approximately (140-150 USD) as an added value, looks like a great solution based on RaspberryPi. The amazing aspect is,  its hardware ecosystem, providing a lightning node which also gives an opportunity to building your personal apps based on LApps. Great step taken, and seems to have very promising future ahead.

running b+ as well - waiting for new power adapter, first one couldn't deliver enough juice for hdd. should have more data in couple days. for standard station usage you might want to do some custom tweaking to get back wifi and local network ssh logins, this might be added later in options or ill post the guide if it works well locally.

if you want to use a regular ubuntu/other os - you could just take off the LCD display, burn standard os image and its ready to go

A nice post for them who wants to start the lightning network with RaspiBlitz. Hereby seeing, I found in detail info from what to till what I need in order to set up a network node of my own. A good post to have knowledge about hardware and software and how to set up, in detail information.

Looks like a very promising solution based on RaspberryPi. The best part is, it provides a hardware lightning node and also lays out the path to building your own apps based on LApps. Moreover, it is very low-cost (150 usd) setup and has an amazing hardware extension ecosystem.

the setup is simple, but its recommended to have some basic command line skills. also this could be a great way to learn linux without installing it on windows machine

Wouldn't it be better for you to synchronize with the mainnet on your computer and then copying all the files to your Raspberry Pi? Once you manage to do it, can you post here if everything is working correctly?

my nodes are working good, 0.16.2 over wifi
you could copy synced blockchain on hdd as described here https://github.com/rootzoll/raspiblitz#copy-the-blockchain
