The local mom-n-pop electronics store closed recently, taking with it my source of project boxes. So I built the enclosure and base out of wood which really suits the retro vibe of Morse code. It's great when two hobbies collide.
The details of the project are presented below, but first here's a look at the end result:
Time-lapse photography is cool, and I like both photography and cool things, so I made my own time-lapse camera based on a Raspberry PiZero W. That's a little computer that's half the size of a credit card with built-in WiFi -- it's very similar to what's in your phone without the telephony or the screen, but with a good camera available as an add-on.
I finally figured out some of the mojo necessary to get some good out of gdalwarp. For me the key was to understand the "spatial reference system" (SRS) parameters. Key to understanding that was grokking the "+proj" notation used in the proj program.
This site was lost when the version of WordPress and/or PHP being used got to be too old. I still have access to the database containing the old articles and will be using that to restore some that I found most useful. There may be a new article posted from time to time, also. Just be aware that months or even years between posts doesn't necessarily mean that this site is moribund.
