I'm working on a new physical Martian Clock, similar to Pi-Mars v1, but without the Electron framework, without the external libraries (some had developed security warnings as exploits had been discovered), and is much easier to update/maintain. It also works on a smaller form-factor, and handles leap-seconds in an even more intelligent way, reducing the number of calls to fetch IERS data even further. The clock is almost finished, so look for announcements in the next couple of weeks (or earlier!).
Many of the remaining problems have been fixed, and at this stage the program is working as expected on an RPI4 with MHS35 screen (as well as a window on my dev rig!).
The next step is to get it running on an RPI4 with the official 7“ touchscreen. It will, of course, run as it currently is, but I just need to check everything looks as it should.
