Over at EDN, [Brian Dipert] has been tearing down web cameras. A few months ago, he broke into a bargain basement camera. This time, he’s looking into a premium unit. Although we have to admit from some of what he reports, we are a little surprised at some of the corners cut. For example, it’s […]
Advanced technology played a crucial role in determining the winner of the men’s 100-meter final at the Paris 2024 Olympics. In a historically close race, American sprinter Noah Lyles narrowly edged out Jamaica’s Kishane Thompson by just five-thousandths of a second. The final decision relied on an image captured by an Omega photo finish camera […]
In the late 1800s, the stereograph — sometimes incorrectly called a stereopticon — was a big craze. You’d view two side-by-side images through some lenses and see a three-dimensional image. This, of course, later would morph into View-Masters and, eventually, virtual reality headsets. But if you have an old stereograph, where do you get new […]
Most digital cameras these days come with some kind of electronic remote shutter release. Various solutions exist, using USB cables, smartphone apps, or dedicated remotes. [Steloherd] wasn’t happy with the options available for his Ricoh GRII, though, so built a rig to do things the old fashioned way. The spring plate helps protect the shutter […]
The unarguable benefits of digital photography has rendered the analog SLR obsolete for most purposes. This means that a wide selection of cameras and lenses are available on the second hand market for pennies on the dollar, making them ripe targets for hacking. [drtonis] decided to experiment with a quick and easy digital conversion to […]
Have you built a 3D scanner yet? There’s more than one way to model those curves and planes, but the easiest may be photogrammetry — that’s the one where you take a bunch of pictures and stitch them into a 3D model. If you build a scanner like [Brian Brocken]’s that does almost everything automatically, […]
Those of us who trawl the world of cheap imported goods will most often stay in our own comfortable zones as we search for new items to amaze and entertain us. We’ll have listings of electronic goods or tools, and so perhaps miss out on the scores of other wonders that can be ours for […]
A common measurement for circuits is heat dissipation inspection. While single point thermometers do the trick, they can be quite annoying to use. Meanwhile, a thermal imaging camera is often out of the budget for hobbyists. How about building your own visual thermometer for cheap? That’s what [Thomas Fischl] decided to do, using an infrared […]
Camera traps are a very common tool in wildlife conservation and research, but placing and pointing them correctly can be a bit of a guessing game. Something very interesting could happen just out of frame and you’d be none the wiser. The [Andrew Quitmeyer] and [Danielle Hoogendijk] at DINALABS (Digital Naturalism Laboratories) in Panama are […]
Honestly, we never wondered how those old film cameras used to put the date stamp in the lower right-hand corner of the frame. Luckily, [Ben Krasnow] does not suffer from this deplorable lack of curiosity, and his video teardown of a date-stamping film camera back (embedded below) not only answers the question, but provides a useful […]
