Oh my gosh that is totally charming! The clock i repurposed for ours has a bit too much of a "this belongs in an office" vibe. Fun to see how different the same idea ends up. I had the same concern about kid-proofing, but I took the route of putting mine on the wifi and using NTP instead of an RTC. (Because it knows the date, it plays different patterns on holidays and on his birthday.)

Yes I didn't have the pico w but in retrospect it would be nice to be able to change the wake up time remotely when you want to sleep in a bit!
