We all know how useful post it notes are to remind us of the many things we have to do in our busy lives, well now you can build your very own electronic version.

The guys over at Popsci have built an electronic post it note, a very cool idea.

“Pick up milk.” “Feed dog.” “Finish homemade nuclear sub.” Like many people, I can’t function without writing little reminders to myself. But using one paper sticky note after another causes a lot of clutter and can be pretty wasteful. Instead, assemble a bunch of surplus parts into a digital note system for your kitchen or office. Just write out your message with your fingertip on a computer trackpad, and it appears on an LCD screen.

When you’re done, press a button and the screen is erased. Add a rechargeable battery and an enclosure, and you have unlimited (and eco-friendly) note-making capability. The project does require some computer code to drive the LCD; you can copy it here. If you can just remember that, you’ll be good to go.

Head on over to Popsci for full instructions on how to make your own electronic post it note.
