High Speed Chronograph Looks Like Pro Gear

It can be hard enough to take a good photograph of a running kid or pet, and if we’re being honest, sometimes even stationary objects manage to allude our focus. Now imagine trying to take a picture of something moving really fast, like a bullet. Trying to capture the moment a fast moving projectile hits an object is simply not possible with a human behind the shutter button.

Enter the ballistic chronometer: a device that uses a set of sensor gates and a highly accurate timer to determine how fast an object is flying through it. Chronometers that operate up …read more

Hyperspectral Imaging – Seeing the Unseeable

They say that a picture is with worth a thousand words. But what is an image exactly? One way ideal would be a perfect reflection of what we see. But our view of the natural world is constrained to a bandwidth of 400 to 700 nanometers within the electromagnetic spectrum, so our cameras produce images within this same bandwidth.

For example, if I take a picture of a yellow flower with my phone, the image will look just about how I saw with my own eyes. But what if we could see the flower from a different part of the …read more

Interference Scanner with Clear Instructions

Meticulous. Thorough. Exacting. These are all words we’d use to describe this video by [BrendaEM] about her Homemade 3D Optical Interference Scanner which can be seen after the break. The scanner uses 3D-printed parts and repurposed materials you might find lying around in your spare parts bin. An old optical drive tray acts to move the laser-wielding sled while a stripped-out webcam is an optical sensor. Links to relevant files such as 3D models and Arduino sketches will be found in the video’s author section.

The principle of operation is demonstrated with a water analog in the video at 2:00 …read more

Giving a 4k Webcam Special Eyes

It’s a problem as old as photography: your camera is only as good as your lens. As cameras shrink, so do lenses, and so do the options for upgrading to a better lens. And forget about switching to a different focal length or aperture — it’s often just not an option. Unless you make it an option by adding a CS lens mount to a high-end webcam.

We’ll stipulate that at 4k resolution and packed with all sorts of goodies, the Logitech Brio Pro is a heck of a nice camera. And the lens isn’t bad either, as you’d hope …read more

Take a Time-Lapse or Bake a Cake with this Kitchen Timer Panning Rig

Seems like the first thing the new GoPro owner wants to do is a time-lapse sequence. And with good reason – time-lapses are cool. But they can be a bit bland without a little camera motion, like that provided by a dirt-cheap all-mechanical panning rig.

Let’s hope [JackmanWorks]’ time-lapse shots are under an hour, since he based his build on a simple wind-up kitchen timer, the likes of which can be had for a buck or two at just about any store. The timer’s guts were liberated from the case and a simple wooden disc base with a 1/4″-20 threaded …read more

A Compact, Portable Pantograph Camera Slider

Ho, hum, another camera slider, right? Wrong — here’s a camera slider with a literal twist.

What sets [Schijvenaars]’ slider apart from the pack is that it’s not a slider, at least not in the usual sense. A slider is a mechanical contrivance that allows a camera to pan smoothly during a shot. Given that the object is to get a camera from point A to point B as smoothly as possible, and that sliders are often used for long exposures or time-lapse shots, the natural foundation for them is a ball-bearing linear slide, often powered by a stepper motor …read more

Yes, Of Couse Someone Shot the Eclipse on a Game Boy Camera

This one shouldn’t surprise us, but there is something particularly enjoyable about seeing the total eclipse of the Sun through a Game Boy camera.

The Game Boy got its camera accessory back in 1998 when CCD-based cameras with poor resolution were just becoming widely available to the public. This camera can capture 128×112 pixel images in the four value grey scale for which the handheld is so loved.

Having taken part in eclipse mania ourselves we can tell you that unless you did some serious research and prep for photographing the thing, this makes as much sense as pulling out …read more

Live Stream to YouTube by Pointing a Box and Pressing a Button

YouTube has the ability to do live streaming, but [Tinkernut] felt that the process could be much more straightforward. From this desire to streamline was born the Raspberry Pi based YouTube live streaming camera. It consists of a Raspberry Pi with some supporting hardware and it has one job: to make live streaming as simple as pointing a box and pressing a button. The hardware is mostly off-the-shelf, and once all the configuration is done the unit provides a simple touchscreen based interface to preview, broadcast live, and shut down. The only thing missing is a 3D printed enclosure, which …read more

Shoot the Eclipse with a Phone and Do Not Go Blind

So you want to photograph Eclipse 2017 but you don’t want to rush out and buy an expensive DSLR just for the event? Not a problem, if you build this simple smartphone filter and occluder.

It all started innocently enough for [Paul Bryson] with his iPhone and a lens from those cheap cardboard eclipse glasses we’re starting to see everywhere. Thinking that just taping the filter over the stock lens would do, [Paul] got a painful faceful of sunshine when he tried framing a shot. Turns out the phone body was not big enough to blot out the sun, and …read more

DIY Illuminator for UV Fluorescence Photography

The image shown is the mineral Hackmanite, which fluoresces under ultraviolet lighting. However, not all UV is created equal, and that makes a difference if you’re into UV imaging. The image for this article is from [David Prutchi] and shows the striking results of using different wavelengths of UV. [David] goes into detail on how to make your own DIY Long, Medium, and Short-wave UV Illuminator complete with part numbers and wiring diagram. The device isn’t particularly complicated; the real work was determining the exact part numbers and models of lamp, filters, and ballasts required to get the correct results. …read more
