I thought of a WiFi+NTP variant, but I haven’t played with the various ESPxxxx WiFi modules that are in vogue for Arduino and the like. From what I know about those, it’d probably be easiest to ditch the board’s ATTiny841 and just add support for the bit-banged SPI display controller directly to the ESP itself.
That said, you could probably add that same support - or even support for *proper* SPI - to the Pi as well. I’m using the MAX6951 for this, and I like it a *lot*.

I hate the alarm clock that I have since to change the time or alarm you have to hold a button and let the time cycle around until it gets to where you want it. If you go too far, you have to do it all over again. It takes a couple of minutes to change a time. Luckily, I seldom use an alarm clock.

I'll probably run it off one of the $5 Sirf-III GPS modules... those things can track GPS down in darkest bowels of Heather's dungeons.
> Heather has the GPS, time zone, DST, alarms, clock display (analog and/or digital), etc already in there. The next version can run keyboard scripts if you press F1 .. F10 so you can set common alarm times and configs in the scripts and call them up from the on-screen touch keyboard. Plus it can sing the quarter hours, crow at sunrise/sunset, sound church bells at solar noon, etc.
