Propane Systems for Expedition Vehicles

June 1, 2008 – 6:43 pm

Perhaps no other system on an expedition vehicle is as wrapped in mystery or inspires as much outright fear as the propane system.

With its inherently explosive nature and its bewildering variety of connectors, it is easy to understand why the typical overlander avoids the design and implementation of a propane system if at all possible.

Once the propane system is designed and installed the challenges do not evaporate. Instead, the overlander who ventures overseas is faced with the daunting task of refilling their propane tank(s) or bottle(s). To refill, they must decipher a highly regulated supply chain and communicate complex concepts and schedules in the local language.

And, if the refilling quest fails, they must do the task on their own, using materials at hand.

All of this adds up to a lot of motivation to avoid a propane system in your expedition vehicle if at all possible. Unfortunately, the alternatives all present significant challenges and/or downsides of their own, so most of us end up with a propane system in our expedition vehicles.

However, all is not lost. Propane need not be a mystery, propane systems need not be arcane, and refilling overseas need not be daunting.

This document attempts to:

  • Explain the basics of Liquid Petroleum Gas (LPG / LP), commonly known in the U.S.A. as propane
  • Define the elements of a typical expedition vehicle propane system
  • Document the types of materials and connectors used in a typical expedition vehicle propane system
  • De-mystify the utilization and refilling of a propane system while overseas

I welcome feedback, improvements and corrections, especially from propane/LPG/LP professionals.

Field Fix: Garmin MapSource Registry Error

May 22, 2008 – 6:36 pm


Background:

Garmin MapSource (GMS) is software provided by Garmin with some of its map products. GMS is used to create, edit and manipulate waypoints, routes and tracks. GMS is also used to upload and download GPS data to and from Garmin GPS receivers.


Problem Description:

Garmin MapSource (GMS) will not load/start if its registry is corrupted.

Lightroom Edit Capture Time XMP vs. EXIF

May 22, 2008 – 2:50 pm

Scope:
- Lightroom (LR) 1.4.1 and 2 Beta
- Any file that is edited using Metadata:Edit Capture Time
(Note: detail info below may be helpful to those seeking to understand date/time problems/issues with LR and other tools)

Background:
LR allows editing/offsetting of image capture time via the “Metadata:Edit Capture Time” menu option.

Changing the time in LR alters the following EXIF date/time metadata fields as displayed in LR:
- Date Time Original
- Date Time Digitized
- Date Time

Writing the LR metadata to the image file via the “Metadata:Save Metadata to File” command writes the values into the image’s relevant EXIF and XMP date/time metadata fields.

Challenge:
LR writes the correctly edited times into the XMP date/time metadata fields but writes incorrect times into the EXIF date/time metadata fields.

LR uses XMP date/time metadata fields for its displayed time data, not EXIF date/time metadata fields. As a consequence, the user does not know the EXIF time fields have been incorrectly changed unless they check them in a tool that displays or uses the EXIF date/time metadata fields.

Solution:
Use a batch file based on exiftools to copy the LR edited XMP date/times into the EXIF date/time metadata fields.

Rare Rewards

The rewards of travel are many.
 
Some are small and some are big.
 
And some rewards, the rarest rewards, are both at the same time.

How To Create Route Maps

April 16, 2008 – 3:32 pm

Garmin GPS to Google Earth
 
For this task I use GPSBabel, a great little donateware utility, to generate the Google Earth KML files from GPX files created by Garmin Mapsource. The procedure for creating the GPX files from Mapsource is detailed in the next section.
 
 
 
GPS waypoints and associated photos to Google Maps
 
Let me begin by saying there have got to be better, more automated and more professional ways to go about getting waypoints from your GPS and associated photos into Google Maps than my method.
 
Second disclaimer: The days of my putting food on the table by writing code are long past. These days I teach myself as much as I need to get something to work and stop right there. Consequently, my method for this process grew, bit by ugly bit, out of necessity, and was never intended for anything but internal use. My process is, unfortunately, a world class kludge and requires some manual steps.
 
If you do a search on “gpx to google maps conversion” you will get a lot of hits. There are also lots of things that put up geocoded photos into Google Maps, so I would guess someone has built a decent solution for this by now.

Route Map Photos Update

April 16, 2008 – 1:08 pm

 

You can get an idea of the places where we are camping by viewing the photos on the route map waypoint markers.

I added 800 pixel size photos to the route map waypoint markers to make the photos more useful.

To see the large photos:

  1. Access the route map here: http://www.hackneys.com/travel/index-routemap.htm
  2. Click on a South America waypoint marker
  3. If there is a thumbnail photo displayed in the info window, click on the thumbnail photo
  4. The large photo will open in a new window. You may need to expand the window to see the full 800 pixel size image.

We’ve got photos in almost all of the South American waypoint markers. There are also a few on the route from San Diego to the Houston Docks.
