I carried the miniCard for a morning, and I noticed it was tricky to set the heading properly. Since I had a physical switch, I had to position the device and press the button. Unfortunately, I had to twist and turn to reach it, and I couldn't have it inside anything, like a case. Maybe I will need to change the delay between the press and the calibration to ten seconds. That should be enough time to press the button, stow it, and face north. I realized this battery only lasted three hours, whereas the previous one ran for twelve.
I keep a few drawers with empty containers, like old pill bottles, mint tins, and candy jars, so I always have project holders. This time I found an acrylic box. Acrylic doesn't like cutting or drilling, so I used a hot soldering iron to make a hole in the bottom, then a drill bit to chip out the slag. I had to relocate the vibrating motor and battery, so it fits, but I got it all in. Now I can carry it without snagging in my pocket.
