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 LCDs, 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.
