Parametric Automated Filter Wheel Changer by jpearce

Last crawled date: 3 years, 1 month ago

This Arduino-controlled open-source automated filter-wheel changer is set up to move to 8 different filter positions. Normally these devices are used in scientific experiments that need good optics. Commercial versions cost over $2,500 and you can make this yourself for less than $50. So if you make just one -- you more than justify the purchase of your own open source 3-D printer!
This component is part of the Open-source optics project, whose goal is to radically reduce the cost of scientific optical hardware:by the Michigan Tech's Open Sustainability Technology Research Group.
