Maybe you've created your own AR program for wearables that shows the definition of a word when you highlight it IRL, or you've built a personal calendar app for your family to display on a monitor in the kitchen. Whatever it is, I'd love to hear it.

I made a safe-to-wake light for my son out of a Raspberry Pi. It serves up a responsive website on the local network so you can manually change the lights or update the schedule.

Been running like a champ for over 3 years now, which has been the most pleasant surprise. I'm used to ecosystem entropy causing things to break.

I documented my adventures in a 6-part series: https://ajpierce.com/2020-01-04_safe-to-wake-pt1/
