I’m starting a company that makes campfire scented cologne, and to solve a problem in my production process, I built a transmissometer. Here is the video Aaron Kowalski and I made with Element 14‘s support:
Transmissometer from Pumping Station: One on Vimeo.
Here are more details on the device, including photos, schematics, and source code.
Thanks to everyone who helped out with the build and filming!
