In this video I demonstrate the latest and greatest software for the home-made Raspberry Pi Spectrometer with al new features! If you already have a Raspberry Pi, this useful tool can be built for under 100 bucks!

The new software features:

Accuracy has been significantly improved by implementing multi-wavelength calibration and a Polynomial regression data fit to compute wavelengths as precisely as possible across the measured range.

Full screen spectrometer display! On Raspberry Pi systems, the interface is designed to fit 800 x 480 screens, which seem to be a common resolution for RPi LCD's, paving the way for the creation of a stand alone benchtop instrument. (for example the HyperPixel 4.0, etc)

Waterfall display from measuring spectra changes over time

This uses readily available components and easy to use Python software I have written specially for this application.
