The ESP32 keeps finding new jobs in my house.

Spectroscopy seems simple: split a beam of light into its constituent wavelengths with a prism or diffraction grating, and measure the intensity of each wavelength. The devil is in the details, though ...

Gamma spectroscopy with a Raspberry Pi Pico 2 Using a small custom PCB, a Raspberry Pi Pico 2 microcontroller, a scintillator (typically NaI (Tl)) and SiPM you can build your own gamma spectrometer!

Spectroscopy is the study of the interaction between light and matter. From testing whether a fruit is ripe to space exploration and determining atomic structures, this field of study is widely used.

Play around with optics long enough and sooner or later you’re probably going to want a spectrometer. Optical instruments are famously expensive, though, at least for high-quality units. But a useful ...

Visible absorbance spectroscopy is a widely used tool in chemical, biochemical, and medical laboratories. The theory and methods of absorbance spectroscopy are typically introduced in upper division ...
