I am retiring the existing design, since a major component is no longer available. Since we started selling the sensor kit in 2014, there has been consistent interest in it from makers and researchers working with 3D filament. Commercial and Industrial sensors that do this cost 10X more, and so I want to continue to provide this option to makers out there.
Over the years customers have shared a number of requests for improvements, so I am working on rolling as many in as I can, while keeping the design relatively low cost.
The new design will be Arduino compatible to allow custom programming, and also provide digital I/O, in addition to the standard analog output. I will also work on whether it's feasible to measure the diameter in two dimensions.
I am currently researching new linear array image sensors to replace the existing sensor (TSL1401CL) and building some rough prototypes with two candidate sensors.
My goal is to have the new sensor ready by early 2021.
