Only $5 for 10 PCBs and every new member get $5 bonus. + Express 24 hour / 48 hour service on pcbway.com ➠ ➠ ➠ In this video, I present the an improved version of my decade resistor box using inexpensive 11-position rotary switches. These switches are much more robust and, having 11 positions, offer a ‘0’ position on either end, making them more practical to use.
To make this as self-standing a project as possible, I include the entire process, from designing the custom PCB to creating 3D-printed enclosures for two versions of the box: a compact 3-range model and a full 9-range version. I also designed custom knobs for the switches, ensuring both functionality and aesthetics.
The video covers the assembly and testing of the resistor box, demonstrating its practical use and accuracy. For those interested in making their own, I’m providing all the necessary files, including 3D print files, a schematic, a BOM, and Gerbers for the PCB, at the following link below.
Whether you’re a hobbyist or a professional, this affordable and customizable tool could be a great addition to your bench.
