It looks like it would be pretty easy to motorize a display like this by adding rack-and-pinion gearing and steppers - something like that could make an interesting clock. That’s good, because this looks ripe for hacking. has shared the library, and it looks like you can get the build files for the mechanism from the original project. He also built an Arduino library to read the current state of the segments it supports the full hexadecimal character set, or even duodecimal if you like. The sensors are connected to an Arduino Nano via a 74HC165 parallel-load shift register, which lets multiple modules be daisy-chained together. Next, he embedded rare earth magnets in the slides and installed seven Hall effect sensors in the frame. ’s take on this theme started by building his display from laser-cut plywood pieces, which is a nice choice because of the good contrast between the white wood and the engraver segments. By sliding these strips up and down relative to each other, the standard nine digits, plus a few other characters, can be composed. The idea for this comes from the “DigiTag” display, which we covered back in October, and divides a standard seven-segment character into three vertical strips - two skinny ones for the outside vertical segments, and one wide strip holding the horizontal elements. Perhaps, but we like where is going with “InSlide,” the seven-segment input device. Using them as inputs would just be crazy talk, right? But what all these displays have in common is that they’re, you know, displays. We’re used to seeing all manner of seven-segment displays, be they mechanical, electronic, or something in between.
