Description
"Lego felt tip 110" printer connected to an Apple Mac. This is not mind storms, I designed/built/coded it all from scratch including analog motor electronics, sensors and printer driver, the USB interface uses a "wiring" board. This is into a sampled analog input as I couldn't get full enough saturation to trigger the ext interrupt pins. There are also push buttons built into lego bricks for left and right end stop detection.
