![]() They added a camera to the display’s frame which lets it mirror back whatever is in front of it. But we’re glad that didn’t stop them from forging ahead and even building on the idea. Now of course the project was well under way before discovered a similar display from more than a year ago. All 48 Arduino boards receive commands from a Raspberry Pi which is running openFrameworks to generate the animations. Each module is driven by its own discrete Arduino (driving 28 LEDs as they’re apparently not connecting the decimal point). To make things easier, four-digit modules were used, although we still couldn’t resist showing you the well-organized nightmare that is the wiring scheme. ![]() In total there are 192 digits in the display. When you see the video below it’s more than obvious what you’re looking at… partly because the device is being used as an electronic mirror. But the only reason you have to look twice is because it is a still photo. ![]() You can pretty much tell that this is an outstretched hand shown on a large grid of 7-segment displays. ![]()
