A NTP server synchronized to the above GPS receiver. I developed this partly as a learning platform for Internet-enabling microcontrollers, and partly as a dedicated system for keeping my various networked computers on time.
I've converted the entire NATMAP Raster Premium "250K Mosaic", "1M Mosaic", "5M Mosaic" and the 20M small-scale map into PathAway maps. The NATMAP exporter allows individual tiles to be exported. I exported each map at 50% and reduced to 256 colours using the palette included with the PathAway software. The maps fill the exported bitmap up to the edge and the fact that they use an equirectangular projection makes for easy calibration.
In total, the NATMAP maps are a touch under 2GB (565 files). They easily fit on my 8GB SD card, but I suspect they, plus the PathAway software itself, would all be able to (just) squeeze onto a 2GB SD. The breakdown: "250K Mosaic" (514 files, 1.45GiB), "1M Mosaic" (49 files, 337MiB), "5M Mosaic" (1 file, 17MiB), "20M" (1 file, 1MiB).
I also do a bit of cycling for exercise. For that I had scanned the Perth Bike Maps. I finally finished that in the middle of November 2006. Murphy's Law then dictated that freely downloadable electronic versions would be published two weeks later! Exporting the PDFs at 200dpi and converting them to the PathAway 256-colour palette results in file sizes totalling 213MiB (between 21.8 and 35.9MiB each).
I've recently had the opportunity to plant two geocaches:
Don't know what geocaching is all about? See http://www.geocaching.com/ for more information:
So far I've visited six confluences. I didn't know this project existed when I went on a trip during March-April 2002. There were several close to where I had been.
During a two-and-a-bit week trip in April 2003, I visited the following confluences:
