Parametric open-source chopper wheel

pinshape

Summary This wheel is specifically designed for use in optical and optoelectronic experiments. Developed as part of the Open-source Optics project, this component aims to drastically lower the expense of scientific optical hardware by the Michigan Tech's Open Sustainability Technology Research Group. For similar projects see the Open-Source Lab How to Build Your Own Hardware and Reduce Research Costs Instructions Customize the wheel using the OpenSCAD files provided for your specific application. Print on your preferred open-source 3-D printer. Only one number controls the number of slots, with examples including four, ten, and fourteen slot stl files that cover frequencies from low to approximately 1400 Hz. Higher frequencies are also possible if needed. Included is code for wheels with a nut cage designed for secure mounting on a spinning shaft. Find full information here on Appropedia. Thanks go out to Nick for his contribution of the code used in this project. This wheel is part of the Open-source Optics Library: Zhang C, Anzalone NC, Faria RP, Pearce JM (2013) Open-Source 3D-Printable Optics Equipment. PLoS ONE 8(3): e59840. As part of a larger effort to reduce the cost of scientific equipment using open-source hardware, this project contributes to the greater goal of making high-quality tools more accessible to researchers.
