Hackaday will launch cool projects that may stimulate others to expand and enhance it, and even move in a completely new direction. This is the way the most advanced technology continues to evolve.

 


This DIY spectrometer project is a great example of this spirit. It comes from Michael Prathofer, who was inspired by Les Wright's PySpectrometer, a simple device pieced together by a pocket spectrometer and PiCam. As we pointed out at the time, [Les] added many complex instruments to the software, but this does not mean there is no room for improvement.

Michael's goal is to make his spectrometer easier to build and improve the calibration process and overall accuracy. To help solve the former, he performed software calibration on the color filter array on his Fuji X-T2. The advantage of doing so is that it does not require high-power lasers and precision micro locators to ablate CFA, and avoids the possibility of damaging expensive cameras. For the latter, Michael delved into the theories behind spectroscopy and camera optics to develop a process that associates the intensity of light in the spectrum with a specific wavelength at that location. He also conducted some machine learning during this process and trained a network to optimize the response function.
