The dual rotary encoder is a type of knob that is used on several places in the Boeing 737-800 cockpit. Especially on the pedestal where eight of them are needed. You can buy them professionally produced, but for a price from 8 up to 25 dollars.
It was never a question that I want to make a creation by myself. And here it is. A really easy to make version of a dual rotary encoder - already with push button functionality (If you use a rotary encoder with built in push button).
I have cut out the needed gears on my laserbut you can try to 3D print them as well. The needed files are included.
- 3mm acrylic
- 4mm acrylic rod
- 6mm aluminum tube
- 2 rotary encoders example
The download package contains all the 3D print files that you need as well as the dxf files for the gears and a PDF with measurements to include the encoder into your panels.
