Every now and then I think about small spectrometers (my university final year project was one). Today I'm thinking about ways to have a battery-powered spectrometer communicate with a smart device.
The way I did it in the project was to host a web server on the spectrometer and have it act as a WiFi hotspot. This seems massively overcomplicated and gave me an intense dislike of creating webapps.
@piggo Yeah, exactly! Mine had a raspberry pi inside, so another whole load of complexity (plus keeping it updated and dealing with certs and stuff). Just yeah, a big stack of nonsense.
