Reducing size measurement for round noticed – Open Electronics

By Bianchi Gabriele on August 2, 2022

If in case you have a round noticed you most likely use a tape measure each time you need to minimize a chunk of wooden and make pencil marks after you discover the specified size. On this mission we’ll see the way to simplify the method by creating a tool that precisely measures cuts each time. You will not want a tape measure or pencil and every minimize can be precisely the size you need.



The system measures the gap a chunk of fabric strikes alongside a information of the round noticed and shows the size on a smartphone display screen by way of an online utility. The space is measured by putting a wheel over the piece to be minimize, it’ll flip as the fabric strikes underneath it. The rotation is translated into horizontal distance and displayed in inches or millimeters. Within the first picture we see the required elements and within the second the wiring diagram, we use a Wemos D1 board (primarily based on the ESP8266).
