Each maker wants a set of digital calipers, even when they’re the $20 variety that actual engineers and machinists scoff at. Sadly, all of these $20 calipers are 6” fashions and a few issues occur to be longer than 6”. To handle that mismatch, Matty Benedetto of the Pointless Innovations YouTube channel constructed these gargantuan digital calipers which are sufficiently big to measure virtually something.
Benedetto participated on this yr’s YouTube Maker Secret Santa alternate and drew Austin Bradley. These ridiculously outsized digital calipers are Benedetto’s present to Bradley.
This construct was really simpler than you would possibly besides. The large calipers show the measurement in inches on two scaled-up seven-segment shows (precision wasn’t a priority). An Arduino UNO R4 WiFi board measures the space between the jaws utilizing a ToF (Time-of-Flight) sensor.
Many of the mechanical elements had been 3D-printed on ELEGOO OrangeStorm Giga and Bambu Lab H2D machines, with laser-cut acrylic panels for diffusing the show LEDs and for the dimensions. The markings on that scale had been made on a sticker printer.
Now Bradley can measure particularly huge issues to the closest inch!
