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 created a todo thermal printer so that I can write messages whenever I remember something. For example when I'm lying in bed and I remember that I have to do something or reading a book and think that's a great thought that I should look more into someday.

Basically I have a mobile app that I can send a message to a api. Sometimes it's just a note, sometimes it is a todo item.

Then I have a raspberry pi that polls the api for new messages and prints them onto a receipt/thermal printer on my desk. Then every morning I usually look and see if there is a todo item, or more long term item.

I haven't exactly thought of how to store the messages, but basically when the "receipt" gets to CVS level, I rip it off and store it in in a document shelf organizer. Every few months I'll go through the receipt for any long term touch items.

Thermal paper is nasty stuff. Just sharing it forward.

Hmm interesting. Just looked it up. Seems to be that BPA/BPS is the problem with it. It seems like phenol free thermal paper is the answer to that issue, although there isn't a lot of information on what is used instead.
