If you’ve ever dreamed of building a proper spectrometer, it looks like the ESPROS epc901 CCD sensor is absolutely worth your attention. It’s fast, sensitive, easy to interface with, and at just $24 USD, it won’t break the bank. There’s only one problem: implementing it in your project means either …read more

Digital cameras have been around for forty years or so, and the first ones were built around CCDs. These were two-dimensional CCDs, and if you’ve ever looked inside a copier, scanner, or one of those weird handheld scanners from the 90s, you’ll find something entirely unlike what you’d see in …read more
If you think of a medical x-ray, it is likely that you are imagining a photographic plate as its imaging device. Clipped to your tooth by your dentist perhaps, or one of the infamous pictures of the hands of [Thomas Edison]’s assistant [Clarence Madison Dally].
As with the rest of photography, the science of x-ray imaging has benefited from digital technology, and it is now well established that your hospital x-ray is likely to be captured by an electronic imaging device. Indeed these have now been in use for so long that their first generation can even be bought by …read more
Linear CCDs are an exceptionally cool component. They can be used for DIY spectrometers, and if you’re feeling very adventurous, a homemade version of those crappy handheld scanners of the early 90s. Linear CCDs don’t see much use around these parts, though, which makes [esben]’s Hackaday Prize entry very cool. He’s building a breakout to make using these linear CCDs easier.
A linear CCD module looks like an overgrown DIP chip with a glass window right on top of a few thousand pixels laid out in a straight line. The data from these pixels isn’t output as a series of …read more
