Notes: Enabling NTFS on LG NAS ( N2B1 )

Jotting down some Notes for enabling the LG N2B1 BluRay NAS to read/write NTFS partitioned USB drives using new firmware and the NTFS-3G package.

  1. Flash new N2B1 firmware to enable SSH server so one can get access to the command prompt on the device:
    Tantalus’ N2B1 Firmware
    Author used N2R1 2569t
  2. Enable SSH in the web console and login into the NAS device using a SSH Client.
  3. login as root . See FAQ
  4. if virgin use of apt-get; initialize the repositories using:
    apt-get update
  5. use apt-get to install gcc compiler.
    apt-get install build-essential
  6. apt-get will fail to install libc6 library; use workaround here:

    mv /sbin/init /sbin/init.mv
    touch /sbin/init
    chmod 755 /sbin/init
    dpkg –configure libc6
    apt-get update
    mv /sbin/init.mv /sbin/init

    WARNING: If you execute the first command, you have to execute the last command, before you reboot your NAS-Box

  7. repeat apt-get install build-essential
  8. gcc -v to verify gcc compiler has been installed and is working.
  9. download NTFS-3G from Tuxera.  Author used: ntfs-3g-2010.10.2
  10. untar: tar xvf ntfs-3g-2010.10.2.gz
  11. cd ntfs-3g-2010.10.2
  12. ./configure –prefix=/usr/lib to install to the correct directory. on Author’s system; the system autoconfigured to /usr/local which caused problems during make install.
  13. make
  14. make install as root. or sudo make install
  15. you should then be able to to mount NTFS partitions using:

    mount -t ntfs-3g /dev/sdb1 /mnt/ntfs

Many Thanks to forum.NAS-Portal.org for hosting the information necessary to piece this together.

GTB Black Hole repo-ed fuse cards

While finishing up my Black Hole project; I found the need to replace my rotted fuse cards with some fresh replacments.

Before:

After:

Thanks to Jim (Gott Lieb?) on RGP for helping me figure out the garbled wording. This post has been updated with the fixed WARNING card.

I’ve made the file available in PDF form so Black Hole owners can replace the fuse cards on their machine.

Gottlieb Open Source PopBumper Driver Board?

I just successfully; built my prototype Gottileb PBDB design and have tested them in my Black Hole Pinball project at AustinModders.com. I have decided to release this  design under to the public under the TAPR Non-Commercial Open Hardware License which indicates:

You may make products based upon this design, provided you do not make more than ten units in any twelve month period for your personal use.

The design include the recommended fixes from marvins u-fix it site including both  Power and Fire LEDs. It also features protection circuitry including a barrier diode and a resettable fuse to try an prevent damage to other devices in your machine. The Logic on this board is Low-Voltage tolerant; so it should operate in situations where +5V is low.

The design uses the more readily available and cheaper TIP120 transistor for driving the popbumper coils.

The PCB is designed as a pair; IE you get two boards in the same foot print as the original. I designed it this way to minimize PCB cost, aid in building multiple units, and enabling the boards to be snapped apart after assembly. The board is a two layer PCB with mostly surface mount parts on the top layer to minimize PCB real estate. The TIP120 driver transistor is mounted on the bottom layer again to keep the board size low.

For those without PCB layout tools; a set of two bare PCBs are available from the batchpcb service for under $28. You can purchase the boards from this link:

The Bill Of Materials (BOM) of a pair of boards is available from Digikey for $10.70 (as of the time of this post). A CSV file with the digikey part numbers is here: A8_PBDB.bom.csv

Here’s a package of the materials above as a single download: GTB_A8_PBDB_pkg.zip

Here are some pictures of the prototypes assembled and installed:
