X-Ray Imaging Camera Lens Persuaded to Join Micro Four Thirds Camera

Posted on by

Anyone who is into photography knows that the lenses are the most expensive part in the bag. The larger the aperture or f-stop of the lens, the more light is coming in which is better for dimly lit scenes. Consequently, the price of the larger glass can burn a hole in one’s pocket. [Anthony Kouttron] decided that he could use a Rodenstock TV-Heligon lens he found online and adapt it for his micro four-third’s camera.

The lens came attached to a Fischer Imaging TV camera which was supposedly part of the Fluorotron line of systems used for X-ray imaging. We …read more

$8 3D Printed Photo Turntable uses Upcycled Parts

Posted on by

Whether you’re selling a product or just showing off your latest project, a photo turntable makes video shots a lot easier.  360° turntables allow the viewer to see every side of the object being photographed, while the camera stays locked down. Motorized turntables are available as commercial products costing anywhere from $30 to $150 or so. Rather than shell out cash, [NotionSunday] decided to create his own turntable using a few parts he had on hand and 3D printing everything else.

The motor for the turntable came from the eject mechanism of an old DVD-ROM drive. An Arduino Pro Mini …read more

Microscope DSLR Mount Using PVC & Heat

Posted on by

Microscopes are a great way to see the mysteries of the universe hidden at the smaller scale. When they were first developed, scientists had to rely on illustration to convey their findings through the lens. Thankfully we can  now rely on photography to help us out instead. Many microscopes come with a special port — often called a trinocular port — for mounting a camera. Using this, [Brian] developed a DSLR mount for his microscope using a hacker staple: PVC pipe.

The virtues of PVC pipe are many and varied. It’s readily available in all manner of shapes and sizes, …read more

Gliding To Underwater Filming Success

Posted on by

If you are a fan of nature documentaries you will no doubt have been wowed by their spectacular underwater sequences. So when you buy a GoPro or similar camera and put it in a waterproof case accessory, of course you take it with you when you go swimming. Amazing footage and international documentary stardom awaits!

Of course, your results are disappointing. The professionals have years of experience and acquired skill plus the best equipment money can buy, and you just have your hand, and a GoPro. The picture is all over the place, and if there is a subject it’s …read more

Talking Arduino Tells GoPro What To Do

Posted on by

It’s 2017 and even GoPro cameras now come with voice activation. Budding videographers, rest assured, nothing will look more professional than repeatedly yelling at your camera on a big shoot. Hackaday alumnus [Jeremy Cook] heard about this and instead of seeing an annoying gimmick, saw possibilities. Could they automate their GoPro using Arduino-spoken voice commands?

It’s an original way to do automation, for sure. In many ways, it makes sense – rather than mucking around with trying to make your own version of the GoPro mobile app (software written by surfers; horribly buggy) or official WiFi remote, stick with what …read more

Motorized Camera Dolly Rolls With the Changes

Posted on by

Over the last semester, Cornell student [Ope Oladipo] had the chance to combine two of his passions: engineering and photography. He and teammates [Sacheth Hegde] and [Jason Zhang] used their time in [Bruce Land]’s class to build a motorized camera dolly for shooting time-lapse sequences.

The camera, in this case the one from an iPhone 6, is mounted to an off-the-shelf robot chassis that tools around on a pair of DC motors. The camera mount uses a stepper motor to get just the right shot. A PIC32 on board the ‘bot takes Bluetooth commands from an iOS app that the …read more

Custom Zynq/CMOS Camera Unlocks Astrophotography

Posted on by

Around here we love technology for its own sake. But we have to admit, most people are interested in applications–what can the technology do? Those people often have the best projects. After all, there’s only so many blinking LED projects you can look at before you want something more.

[Landingfield] is interested in astrophotography. He was dismayed at the cost of commercial camera sensors suitable for work like this, so he decided he would create his own. Although he started thinking about it a few years ago, he started earnestly in early 2016.

The project uses a Nikon sensor and …read more

Mod Your Camera With ModBus

Posted on by

Industrial hardware needs to be reliable, tough, and interoperable. For this reason, there are a series of standards used for command & control connections between equipment. One of the more widespread standards is ModBus, an open protocol using a master-slave architecture, usually delivered over RS-485 serial. It’s readily found being used with PLCs, HMIs, VFDs, and all manner of other industrial equipment that comes with a TLA (three letter acronym).

[Absolutelyautomation] decided to leverage ModBus to control garden variety digital cameras, of the type found cluttering up drawers now that smartphones have come so far. This involves getting old-school, by …read more

Instant Camera with This Year’s Hottest Dithering Technique

Posted on by

Digital cameras are great, because you can take thousands of pictures without running out of film. But there’s something to be said for having a tangible image you can hold in your hand. The Polaroid cameras of yesteryear were great for this, but now they’re hard to find and the price per photograph is ludicrously expensive.

Over the past few years, a few people have sought a way to create printed photographs at a lower cost. One of the best ways to do this is to find something much cheaper than Polaroid film — like thermal paper.

[Fabien-Chouteau]’s thermal printing …read more

Raspberry Pi Camera Flash

Posted on by

The Raspberry Pi Camera is a great tool; it allows projects that require a camera to be put together quickly and on a budget. Plus, having a Linux back end for a little processing never hurt anybody. What can be difficult however, is imaging in low light conditions. Most smartphones have an LED flash built in for this purpose. [Wim Van Gool] decided to follow suit and build an LED flash for the Raspberry Pi.

The project consists of a custom PCB with surface-mount LEDs in an attractive concentric layout. This is a good way to get a nice even …read more
