Programming a USB Spectrometer with Python

Описание: In this video, I show how to work with a USB spectrometer in Python, from device connection to high-resolution spectral analysis. Using Python and OpenCV, I process raw spectrometer data, visualize spectra, and modernize an older open-source GitHub project to support higher resolution and cleaner output.

🔬 What this video covers:
Connecting to a USB spectrometer using Python
Reading and processing spectral data with OpenCV
Updating legacy Python code for higher spectral resolution
Displaying real-time and static spectra
Wavelength calibration using a fluorescent light bulb
Comparing fluorescent lamp vs LED lamp spectra
Practical spectroscopy for physics and science projects

💡 Why this matters:
Spectroscopy is a core technique in physics, chemistry, astronomy, and materials science. This tutorial demonstrates how affordable hardware and open-source software can be combined to build a powerful DIY spectrometer system for experiments, education, and research.

📈 By improving the original GitHub code, I explain:
Why calibration is critical for correct wavelength mapping
How to validate results using known emission lines

👨‍💻 Who this video is for:
Python developers and data scientists
Physics and optics enthusiasts
Students working on spectroscopy projects
Makers and DIY scientists
Anyone interested in scientific instrumentation and data processing
