20,000 Leagues Under the Sea

July 5th, 2018

20,000 Leagues Under the Sea is one of my favorite movies. I watched it repeatedly as a child. My favorite thing in the movie was the iconic Nautilus. The Nautilus was designed by Harper Goff for Disney’s 1954 film. I love the mixture of organic and mechanical design. Even as a child, I thought the submarine was pure beauty.

I’ve attempted many times to capture it’s likeness in drawing. I’m not much of an artist, but I think you can tell what the subject matter is.

I finally decided to purchase a model. I found a highly detailed model from Masterpiece Models for $100. It’s a 16 inch model based off the reproduction fabricated by Scott Brodeen. In the Nautilus community, his is a well-known name. He researched and created master models that are the most accurate reproductions available, going as far as to place all of the thousands of rivets as accurately as possible.

The kit was pretty good. I had a few issues with it as I went. As is common with models, there was a lot of flashing that had to be removed. This is a solid resin casting, and not hollow, so there is some heft to it. A few of the mold lines didn’t seems to be lined up correctly which made some of the smaller pieces less uniform that I would have liked. Specifically, the upper part of the nose, and the support struts for the rear rotor cover.

On the main body, there were some defects. The front of the nose was actually missing. It looks like when they filled the mold with resin (from the tail) the resin never reached all the way to the nose, or there was a large amount of air trapped there. I got some plastic and turned it down to an acceptable approximation and glued it on to the front. Some of the rivets also had bubble problems.

After doing the clean-up and most of the assembly, I did a light primer coat of black.

The interior of the wheelhouse I did a clean steel color. I deviated from what the instructions suggested for colors, and did my own based on memories of watching the movie. The wheel and wheel column are gold.

The lights I painted a mixture of yellow and gold paint.

The remainder was painted using a Modern Master’s Reactive Iron Paint that contains ferrous particles that oxidize using an activator containing acid. Following the instructions, I brushed on two coats of the paint. It comes out as a flat, almost gun-metal grey. A tad darker perhaps.

The magic happens when you apply the activator. I re-purposed a small spray pump that had contained eye-glass cleaning solution. I sprayed it on fairly generously, and then let it sit for 5 minutes. I then applied heat from a hair dryer. You can see the how quickly this take effect form the time lapse footage.

Once everything was painted, I had to apply the bubble domes to the lights and windows. The domes (4) were created using vaccuform, and unfortunately were a bit too large for the openings on the resin model. I ended up using a heat gun to soften the domes in order to place them. Once placed, I tacked them in with super glue.

The lights also needed clear bubble coverings. The kit came with 2 different sizes of googly-eyes. The eyes needed to have the backing removed. I kept dropping them, and they are incredibly hard to see. They too were pretty close in size, but there were a few that didn’t fit as well as I would have liked. I use super glue to place these. Of the entire model, I am most disappointed with how well I executed these, however they are a small enough detail that I think it looks okay from a normal viewing distance.

I assembled the remaining components; Hull, wheel-house covering, upper nose, and observation window structures.

I now have my own recreation of the Nautilus that I can enjoy.

Making USB Bootable Windows 10 Installer

May 3rd, 2018

I needed to update some servers to Windows 10/2016 at work this week, but didn’t have any DVDs large enough to accommodate the 5.8 GB size of the Windows ISO. Normal DVD+Rs are 4.7 GB, so to make use of the ISO I downloaded from MSDN, one needs a DVD-R DL which can hold 8.5 GB of data.

I didn’t feel like going to a store or waiting for delivery, so I used Microsoft’s “Windows 7 USB/DVD Download Tool” (seemingly misnamed since it supports windows 7 and newer).

Once downloaded, the tool is fairly straight forward. You point it to an ISO, and then to a USB drive, and voila, it copies the data.

The annoyance is that I got the error “We were unable to copy your files. Please check your USB device and the selected ISO file and try again.” Trying again, of course, did not resolve the issue.

Fortunately, someone knowledgeable was able to explain the root cause of the error. The USB’s MBR needs to be cleared. This doesn’t happen automatically with the Windows Download Tool.

To clear the MBR and format the drive, follow these steps using the diskpart tool:

diskpart
diskpart> list disk
diskpart> select disk #
diskpart> clean
diskpart> create partition primary
diskpart> select partition 1
diskpart> active
diskpart> format quick fs=fat32
diskpart> assign
diskpart> exit

This resolved my issue and I was able to go along my merry way.

I don’t use Windows a lot in my every-day life, but it is something I use quite a bit at work. Documenting little things like this helps me to remember tricks I come across, and hopefully can help other people searching for solutions to similar problems.

NVidia Web Driver Headless Update

April 6th, 2018

I upgraded my graphics card in my 2008 MacPro to an Nvidia 950. This of course requires the Nvidia WebDriver since Apple doesn’t offer built-in support. I installed the driver, swapped my cards, and it worked like a charm.

Today I had a security update from Apple and thought nothing of it. Unfortunately, after the chime, the video never showed up! I didn’t panic immediately. I SSHed into my computer, and told it to reboot just to see if it was a glitch. No luck… I also tried using screen sharing, alas screen sharing doesn’t work without a GPU.

Luckily it is possible to fix this problem with nothing more than an SSH connection to the troubled Mac. I logged in, and ran the command, system_profiler SPSoftwareDataType, to determine which OS Release I have so I can choose the appropriate WebDriver package.

$ system_profiler SPSoftwareDataType
Software:

    System Software Overview:

      System Version: OS X 10.11.6 (15G20015)
      Kernel Version: Darwin 15.6.0
      Boot Volume: Macintosh SSD
      Boot Mode: Normal
      Computer Name: MikePro
      User Name: Michael Caldwell (michaelcaldwell)
      Secure Virtual Memory: Enabled
      System Integrity Protection: Enabled
      Time since boot: 3 minutes

The helpful people at MacVidCards.com keep a handy list of all the up-to-date releases of the WebDriver. I selected the appropriate one and was able to install it over SSH using the installer command (which I didn’t know existed before today!).

$ sudo installer -pkg WebDriver-346.03.15f13.pkg -target /
Password:
installer: Package name is NVIDIA Web Driver 346.03.15f13
installer: Upgrading at base path /
installer: The upgrade was successful.
installer: The install requires restarting now.
$ sudo reboot
Connection to 10.0.1.12 closed by remote host.

After the reboot, the display popped on just like it used to. Crisis averted!
