This project is particularly amusing. It doesn’t have a whole lot of practical use, but it makes up for it in style. They have an SD card with Wikipedia from 2003 downloaded to it. This is accessed with a Parallax propeller microcontroller based system and displayed on a small retro looking screen. We like it. We don’t think we would ever actually use it, but we would definitely keep it around.
[William] sent in this project where he’s using his iPhone to control his TV lift. He’s made a custom PCB with a pic18f122 microprocessor to communicate with the lift. He says it connects to the lift controls via a serial port. You can see a video of it in action after the break. We really think the shadow turning into an arrow is cool. That was a lucky accident.
