[Eddie Zarick] is at it again, modding his Jeep Wrangler into something that makes us all properly jealous. This time, he managed to acquire and mount the FLIR camera from an old Cadillac. It truly is an FLIR thermal imaging camera, and not just a near-infrared hack. Cadillac used this technology with a HUD, but [Eddie] decided to connect it to his in-dash screen. He also didn’t settle for simply facing it forward, but mounted it to a Golight searchlight base. He mounted the joysticks under the screen, giving him directional control.
[Eddie] spent about $500 on the project, which seems like a lot, but not when you consider the cost of a new FLIR camera. We would love to know where he found such a great deal! Maybe he hit up a local salvage yard? If you know of a good source for parts like this, let us know in the comments!
Previously we covered [Eddie’s] pressurized water tap, weatherproof keypad entry, and other assorted hacks. We look forward to seeing what he adds to his Jeep next.

[Kevin] has made an interesting camera shutter mechanism using an Arduino and a solenoid. To keep it extremely simple, he is only controlling a single leaf. In the linked video, you can see him take it through its paces from 1/125 seconds up to infinite. This is, of course, a proof of concept, and [Kevin] mentions using smaller components to make everything fit easily inside a Holga-like body. As he points out in the video’s comments, digitally controlling the flash would be a simple matter as well.
A basic camera is incredibly simple to make, and [Kevin’s] design certainly isn’t complicated. That said, if you look at the big picture, [Kevin] is demonstrating how feasible it could be to build an entirely custom camera with a standard microcontroller as the brain. We can’t help but think of all of the possibilities when you are able to control the entire photo taking process.
Interestingly, [Kevin] is also behind this twin lens reflex Kickstarter project from earlier in the year. It will be interesting to see what other camera-related hacks we will see from him.
A jarring pan with your tripod can ruin a shot in your film, and tilting up or down usually requires some loosening and tightening kung fu to keep gravity from taking over. The “Power Panner” is a remote-controlled device that fits between the tripod and the camera, handling pans and tilts with ease. When [NeXT] found one at the Capitol Flea Market for $5, he didn’t care about the missing remote. He bought the Panner, dragged it home, and hacked together his own remote with a Sega Master Pad.
After researching similar devices online, [NeXT] had determined the original remote’s pinout: essentially a D-pad with adjustable speed control. He decided to ignore the speed pins and to instead search for a suitable replacement controller. A Sega Master Pad offered the most straightforward solution, so [NeXT] went to work separating out the wires and soldering them to a DIN connector. He couldn’t find the right plug to fit the Panner’s DIN-7 jack, so he substituted a DIN-8 with the extra pin snapped off.
Rather than use the remaining two buttons for speed control, [NeXT] chose to feed them directly into his camera to drive the focus and shutter, but the Master Pad’s wiring posed a problem: the camera would have to share the Power Panner’s ground, and the Panner plugs into the wall via a 6V adapter. Fingers crossed, he decided to push ahead and was relieved that everything worked. We suspect the shared ground won’t be a problem as long as one device uses a floating power supply, which the Panner can provide either through the proper wall wart or by using its 4 AA battery option.
If you’re in the mood for more camera hacks, check out the sound-dampening and waterproofing build from last week.
The D-SLR “crunch” sound can be pretty satisfying. Your camera has moving parts and those cell-phone amateurs can eat your shutter actuation. If you’re a professional photographer behind the scenes on a sound stage or at any film shoot, however, your mirror slapping around is loud enough to get you kicked off the set. [Dan Tábar] needed his D800 to keep it down, so he made his own sound blimp to suppress the noise. As an added bonus, it turns out the case is waterproof, too!
[Dan] got the idea from a fellow photographer who was using a prefab Jacobson blimp to snap pictures in sound-sensitive environments. Not wanting to spend $1000, he looked for a DIY alternative. This build uses a Pelican case to house the body of the camera and interchangeable extension tubes to cover lenses of various sizes. [Dan] took measurements and test-fit a paper cutout of his D800 before carving holes into the Pelican case with a Dremel tool. One side got a circular hole for the extension tubes, while the other received a rectangular cut for the camera’s LCD screen and a smaller circle for the viewfinder.
Lexan serves as a window for all of the open ends: LCD, viewfinder, and the lens. [Dan] snaps pictures with a wireless trigger, saving him the trouble of drilling another hole. You can hear the D800 before and after noise reduction in a video after the break, along with a second video of [Dan] trying out some underwater shots. If you’d rather take a trip back in time, there’s always the 3D printed pinhole camera from last week.

To take a color image, modern digicams have something called a Bayer pattern – small red green and blue filters, one color for each pixel – that drastically reduce the resolution if all you’re doing is taking black and white pictures. [Lasse] is an astrophotographer, and doesn’t exactly need color pictures, so he decided to swap the color sensor in his camera with a monochrome CCD.
Most DSLRs have CCD sensors on strange surface mount packages or put everything on flex PCBs. [Lasse]’s Olympus E-500, though, features an 8 Megapixel CCD on a ceramic DIP that is actually fairly easy to remove given the right tools and just a little bit of mechanical encouragement.
After putting in a new monochrome CCD, [Lasse] had a much more sensitive sensor in his camera, and processing the RAW files off the camera gives him a great improvement for his astrophotography.
This isn’t [Lasse]’s first adventure in tearing apart DSLRs for astrophotography. Earlier, he uncovered the secrets of the Four Thirds lens format with a logic analyzer, making his Olympus camera a wonderful tool for looking into the heavens.
While most of us are familiar with pneumatic transport systems by their use at drive-up bank windows, these systems are also commonly found in hospitals ferrying samples around. When [Aidan] was in the hospital, he asked how this series of tubes routed samples from many different floors to the lab and back again. Well, give him an old tube to play around with and he’ll eventually come up with a way to record the inside of one of these pneumatic tubes, giving some insight into how this system actually works.
When asked, a tech that uses this system on a daily basis described it as a very basic physical Ethernet that sucks and blows through rotary junctions and physical hubs to route packets to different areas of the building. [Aidan] wanted to record a tube’s travels, so he wired up a small HD camera, a bunch of LEDs, and a few batteries. Sending this recording sample container revealed some of how this pneumatic system works; the containers will travel forward and stop before reversing through one of the rotary switches. You can check out the flight of the container in the video below.
Of course there are other glimpses of how stuff travels through the unseen world of getting from point A to point B. Here’s a time lapse camera going on a trip via DHL just for kicks.

Here’s a quick tip on capturing the output of oscilloscopes that don’t have that native feature. [Paulo Renato] used a cookie tin as a camera cowl for capturing CRT oscilloscope screenshots.
We figure if you’ve got any kind of functioning oscilloscope you’re lucky. And although it’s nice to pull down the measurements to your PC on the newer models, the results [Paul] gets with this rig are still satisfactory. The plastic cookie box he used blocks out ambient light while holding the camera at a consistent focal length. He used some flat black spray paint to make sure the obnoxious yellow plastic didn’t interfere with the image, then drilled a hole which fits tightly around his camera lens.
You’ll need to monkey with the exposure settings to get the best image. But once you’ve got it dialed in it should be the same every time you want to take a picture of the screen.
