On: Show HN: I made an alarm clock

That's really cool, but a projection clock really saves from having to strain to read the time on the bedside table.

Agreed. Reading the time off the ceiling when it's dark is the way to go. I bought one years ago, and it comes with a normal clock and the projector added to the side, and it reads the time via the WWVB time signal.

I 95% like it, but: the normal clock part I never use, and the WWVB syncing sometimes goes out (happening more after 7 years of use), and it reads a time 1-3 hours wrong.

I LOVE the projector part, it's basically all I use. I've been tempted recently to pull it apart and hook it up to some microcontroller that NTP synced and just ran the projector.

I wasn't aware of projection clocks, thanks! I sleep on my side or in a prone position, so a projection clock wouldn't help me, unfortunately.
