Summary of TAPE CUTTER MAKES SHORT WORK OF THROUGH-HOLE RESISTOR REELS
This article describes an automated machine designed to cut resistor tape reels into predetermined lengths. Built by [Sandeep], the project utilizes an Arduino microcontroller, stepper drivers, and a custom PCB to control three motors: one for advancing the resistor reel and two for operating motorized knives that slice both tapes simultaneously. The system is housed in a wooden frame with 3D-printed components and features touch screen control, offering a precise solution for handling through-hole wire-ended resistors.
Parts used in the Automated Resistor Tape Cutting Machine:
- Arduino
- Stepper drivers
- Custom-designed PCB (multipurpose board)
- Three motors (one for advancing reel, two for knives)
- Motorized knives
- Wooden frame
- 3D-printed parts
- Touch screen
As the world of electronics makes its inexorable movement from through-hole parts to surface-mount, it’s easy to forget about the humble wire-ended resistor. But a stack of them is still a very useful resource for any experimenter, and most of us probably have a bunch of them with their accompanying twin strips of tape. We’re entranced by [Sandeep]’s automated resistor tape cutting machine, which uses a fearsome looking pair of motorized knives to slice the tape into predetermined lengths.
At its heart is an Arduino and a set of stepper drivers, and it uses a PCB that he’s designed as a multipurpose board for motor-based projects. One motor advances the reel of resistors, while the other two operate those knives that simultaneously slice the two tapes. The whole is held in a wooden frame with 3D-printed parts, and control is through a touch screen. This feels more like an industrial machine than a maker project, and as can be seen in the video below, it makes short work of those tapes. Full details can be found on his website, including code.
We’ve not had so many through hole tape cutters, but we’ve seen at least one SMD cutter.
