Mr Innovative’s resistor cutting machine is ‘reely’ awesome
If you need some help separating out lots of resistors, then Mr Innovative’s latest automated rig is the perfect solution for you. At the heart of his homemade device is an Arduino Nano, along with a multipurpose PCB for electrical connections and a touchscreen user interface.
The machine advances the reel of resistors through a slot via a stepper-driven rod and o-ring friction wheel assembly. When properly positioned, it cuts off the correct number of resistors using a pair of razors, set in motion by two stepper motors and corresponding linkage systems.
You can see the project being constructed out of wood, extrusion, 3D-printed parts, and more in the video below.
