Rock your Rainbow - Building an Open source Spectrometer
summary
An open-source modular spectrometer platform called Rock Your Rainbow pairs with an OpenDrop device or runs standalone, using a diffraction grating + webcam to capture JPEGs and convert pixel intensity to spectra. The prototype reproduces a compact fluorescent lamp’s mercury peaks, supports chromatographic pigment analysis (chlorophyll, saffron, lycopene extraction protocol) and claims nanometric precision for lab-grade quantification. Hardware needs refinement but the build works, enables soil/water/endocrine-disruptor testing, and standardizes procedures across contributors as an open modular platform.
