I picked up some arduino boards a few months ago and built a simple digital thermometer with a 4 digit 7-segment LED display. This worked reasonably, aside from some poor connections caused by prototyping on a breadboard.

Unfortunately, the poor connections meant that the temperature did not update reliably, so I replaced the project with a $2 off-the-shelf unit.

But after stumbling across this Printer project I think I might have found my next job for the boards I have.

I imagine this would be fun to have and perhaps even a little useful. I would like to add a knock sensor to the project to trigger a print, so I could knock on the desk and have my schedule, reminders, weather forecast and whatever else printed.

Project Goals:

Project steps:

  1. Build a parts list
  2. Inventory my parts
  3. Build a shopping list
