* (Unfortunately none of these products are available yet, and probably never will
be. Some of these designs are over 10 years old. There are newer altimeters on
the market from other people that have features mine don't, so my devices wouldn't
sell enough units to make it worthwhile manufacturing them. Also, my host software
was written in Visual Basic 6 (VB6) for Microsoft Windows only (not macOS or Linux),
and Microsoft dropped support for VB6 years ago. I'm reluctant to spend the time it
would take to completely rewrite the host software in another language. Instead, I will
probably eventually just post the schematics and PCB layouts, and maybe the source
code for the microcontroller firmware and VB6 software, in the hope that someone will
find them useful, or at least interesting.)
