An Automated Paper Cutter
Are scissors and manual paper cutters not working for you? Well, “Mr Innovative” has the solution in the form of an Arduino-driven device that cuts paper to length automatically.
As you can see in the video below, a user simply inputs the length of paper and the number of strips needed via a series of buttons and a tiny OLED display, and the automated machine does the rest.
The system works by pulling paper inserted into the machine’s body at precise intervals using a stepper motor and rollers. When in place, a second stepper moves a razor blade over the paper, cutting it into perfect strips for whatever craft project you have in mind. An Arduino Mega controls the device, along with a pair of stepper drivers via designed PCB-shield. Code and PCB files are available here for download.
