Make your own Electronic Post-it Notes
Who needs pen and paper Jot down reminders on a digital screen, using only your finger. A rather complex build, this project uses a few surplus parts and teach you valuable circuitry skills along the way.
Pick up milk. Feed dog. Finish homemade nuclear sub. 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 note-making capability.
