Although it might seem like there was a sudden step change from analog to digital sometime in the late 1900s, it was actually a slow, gradual change from things like record players to iPods or from magnetic tape to hard disk drives. Some of these changes happened slowly within the same piece of hardware, too. […]
These days, everyone’s got a million different devices that can take a passable photo. That’s not special anymore. A camera that draws what it sees, though? That’s kind of fun. That’s precisely what [Jens] has built—an instant sketch camera! The sketch camera looks like a miniature drawing easel, holding a rectangular slip of paper not dissimilar […]
Medium format cameras have always been a step up from those built in the 35 mm format. By virtue of using a much larger film, they offer improved resolution and performance. If you want a medium format film camera, you can always hunt for some nice vintage gear. Or, you could build one from scratch […]
There is a point where taking technology for granted hides some of the incredible capabilities of seemingly simple devices. Optical mice are a great example of this principle, using what are more or less entirely self-contained cameras just for moving the cursor across your screen. Don’t believe us? Check out this camera made from an […]
The advent of the mobile phone camera has caused a revolution in film making over the last couple of decades, lowering the barrier to entry significantly, and as the cameras have improved, delivering near-professional-grade quality in some cases. Mobile phone manufacturers hire film makers to promote their new flagship models and the results are very […]
Hyperspectral cameras aren’t commonplace items; they capture spectral data for each of their pixels. While commercial hyperspectral cameras often start in the tens of thousands of dollars, [anfractuosity] decided to make his own with the Waverider. To capture spectral data from every pixel location in the camera, [anfractuosity] first needed a way to collect that […]
You can get all kinds of great wildlife footage if you trek out into the woods with a camera, but it can be tough to stay awake all night. However, this is a task you can readily automate, as [Luke] did with his DIY trail camera. A Raspberry Pi Zero 2W serves as the heart […]
These days, surveillance cameras are all around us, and they’re smarter than ever. In particular, many of them are running advanced algorithms to recognize faces and scan license plates, compiling ever-greater databases on the movements and lives of individuals. Flock You is a project that aims to, at the very least, catalogue this part of […]
[Curious Scientist] has been working with some image sensors. The latest project around it is a 6K camera. Of course, the sensor gives you a lot of it, but it also requires some off-the-shelf parts and, of course, some 3D printed components. An off-the-shelf part of a case provides a reliable C mount. There’s also […]
A new kind of ‘camera’ is poking at the invisible world of the human body – and it’s made from the same weird crystals that once shook up solar energy. Researchers at Northwestern University and Soochow University have built the first perovskite-based gamma-ray detector that actually works for nuclear medicine imaging, like SPECT scans. This […]
