Spectroscopy seems simple: split a beam of light into its constituent wavelengths with a prism or diffraction grating, and measure the intensity of each wavelength. The devil is in the …read more Continue reading DIY scanning spectrometer is a bright idea
A spectrometer is one of those tools that many of us would love to have, but just can’t justify the price of. Sure there are some DIY options out there, …read more Continue reading Software Hacks Unlock Cheap Spectrometer
A spectrometer is a pretty common lab instrument, useful for determining the absorbance of a sample across a spectrum of light. The standard design is simple; a prism or diffraction …read more Continue reading A Low-Cost Spectrometer Uses Discrete LEDs and Math
[Project 326] wanted to know exactly what gas was in some glass tubes. The answer, of course, is to use a spectrometer, but that’s an expensive piece of gear, right? …read more Continue reading Spectroscopy on the Cheap
Here at Hackaday, we love it when someone picks up the ball from a previous project and runs with it. That’s what we’re all about, really — putting out cool …read more Continue reading An Improved Spectrometer, No Lasers Required
If someone asked you to measure a change in distance at about one ten thousandths of the diameter of a proton, you’d probably assume you would need access a high-tech …read more Continue reading Measuring Nanometers at Home
Here at Hackaday, we love to see projects re-visited and updated after we’ve covered them on the site. It’s always exciting to see what the creators come up with next, …read more Continue reading Pi-based Spectrometer Gets An Upgrade
Here at Hackaday, we love projects that result in useful lab equipment for a fraction of the cost of professional gear. [Lorenz], over at Advanced Tinkering, built his own instrument …read more Continue reading Spectrometer Detects Chemicals by Zapping Samples With a Laser Beam
It’s an age-old riddle: if you have a perfect sphere with a perfectly reflective inner surface, will light bounce around inside it forever? The answer is pretty obvious when you …read more Continue reading Cannonball Mold Makes a Dandy Integrating Sphere for Laser Measurements
A Bayer array, or Bayer filter, is what lets a digital camera take color photos. It’s an array of tiny color filters that sit on top of a camera’s CCD. …read more Continue reading Using a Laser to Blast Away a Bayer Array
