 So here I am, a physicist who got bitten by the color science bug. What started as innocent curiosity about how light works has turned into a full-blown obsession with spectrometers, colorimeters, and now... laser power meters. You know how it goes - you start with one simple question and before you know it, you're knee-deep in soot-covered copper plates and differential amplifiers at 3 AM.

 After successfully reverse engineering the CR30 colorimeter, I found myself wanting something more versatile - a device that could not only measure reflected light but also handle transmittance measurements with fiber optic coupling. The result is this compact, portable visible light spectrometer built around a Raspberry Pi Zero 2 W and some clever optical engineering.

 I've always been fascinated by the intersection of hardware and software, especially when it comes to understanding how devices communicate. Recently, I developed a need for monitor calibration as well as properly color correct my photos. I've been looking at X-Rite, Datacolor and other calibration devices and am on the path of acquiring one of those. However, in the meantime I got this idea of creating a simple color chart that could substitute one of those ColorChecker24 cards for simple color correction. For that I needed to print an accurate replica of one of those charts so that Darktable and/or Davinci Resolve would recognize it. Of course it is impossible to do due to various reasons, but it is possible to produce one close enough for regular use(not scientifically accurate at all). For that purpose I have an old sublimation printer that only has CMY colors. Clearly not enough to produce the full gamut, but close enough. Or so I thought...
