Should a camera build start with a sand mold and molten aluminum? That’s the route [CroppedCamera] took with this thoroughly impressive camera project.
When we think of cameras these days, chances are we picture the ones that live inside the phones in our pockets. They’re the go-to image capture devices for most of us, but even for the more photographically advanced among us, when a more capable camera is called for, it’s usually an off-the-shelf DSLR from Canon, Nikon, or the like. Where do hand-built cameras fall in today’s photography world? They’re a great way to add a film option to your camera collection.
Cast lens body before machining
[CroppedCamera] previously built a completely custom large-format view camera, but for this build he decided that something a bit more portable might do. The body of the camera is scratch-built from aluminum, acting as the lightproof box to hold the roll film and mount the leaf-shutter lens. There’s an impressive amount of metalwork here — sand casting, bending, TIG welding, and machining all came into play, and most of them new skills to [CroppedCamera]. We were especially impressed with the shrink-fit of the lens cone to the body. It’s unconventional looking for sure, but not without its charm, and it’s sure to make a statement dangling around his neck.
It’s tough to find non-digital DIY camera builds around here — best we could do were these laser-cut plywood modular cameras. Then again, you can’t beat this wearable camera for functional style.

[Glitchmaker] loves photography and wrote in to tell us about his newest project. He has a Canon 1000D camera but, unfortunately, it does not have time lapse capability. So, instead of shelling out a chunk of change for a new camera [Glitchmaker] decided to make an external shutter control device that can continue to instruct the camera to take photos at predetermined intervals. He calls his project: SHTTTRRR. You didn’t think that meant something else, did you?
You can see the unassuming box above, there is just enough stuff packed in there to get the job done, nothing extra or fancy. Luckily, the Cannon camera has a remote shutter input jack that only requires connecting one pin to another in order to take a photo. Inside the box is an ATTINY45 microcontroller. It reads the button pushes from the single panel-mounted button and calculates the time between two button presses. That time between button presses determines the frequency of the photos taken. At the appropriate times, the ATTINY45 signals a transistor to connect the two appropriate pins on the camera’s remote shutter input jack. The device continues to tell the camera to take photos until it is shut off. The result is a series of time-lapse photos that was previously not possible on that camera!
This is a simple project that solves a problem and gets the job done. What’s better than that? [Glitchmaker] is proud of the SHTTTRRR he made and also learned a bunch about programming the ATTINY45 along the way. Check a video of it working after the break.

[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.
Just the other day we were reading a Reddit thread asking about how to control a television with a smartphone. The conversation started by talking about adding an IR LED to the phone. Then it was suggested that there should be standalone Bluetooth devices that convert commands to IR, and came around to the ideas that TV’s should ship with native Bluetooth hardware. We couldn’t agree more but we’re also not about to replace our TV just for this option. That’s why we were delighted to find this project waiting on our tip line. It’s a method of controlling a camera shutter from a smartphone using Bluetooth. But the technique will work for any device which uses an infrared remote control.
The video after the break shows two different devices controlling the camera shutter. As you can see in the diagram above, the iPhone is the master controller, connecting to a Bluetooth headset mounted on the camera. That headset was altered to feed the speaker connections into an IR LED pointed at the camera’s receiver. The iPhone plays an encoded audio track matching the IR remote command, resulting in the properly formatted message flashing on the LED. The watch doesn’t have the ability to playback audio, but it can send a message to the phone, which then plays the proper audio track through the headset.

[Fotoopa] keeps churning out new iterations of his laser-triggered camera rig. This is his latest, which he calls the 2011 setup. Regular readers will remember that we just covered a different version back in November; that one was the 2010 rendition. It had two DSLR cameras offset by 90 degrees with mirrors to face forward. This time around he has gone back to the single camera setup which was what he used on the first and second versions seen way back in 2008.
Whew, that’s a lot of links to specialty DSLR hardware. Let’s bring it back to this newest model (the link at the top). The biggest improvement is the shutter delay between when the laser beam is tripped and the image is take. [Fotoopa] reports that he’s managed to reduce that time down to 3.3 milliseconds. This is thanks to an external shutter replacement which improves on the stock shutter’s 52 millisecond delay.
For those that are seeing this for the first time. [Fotoopa] uses this rig to photograph insects in motion. A laser trip wire is responsible for triggering the shutter, and it does so with stunning results!
Since most DSLR cameras now have an IR communication port, [Julius] thought it would be a good idea to build an IR shutter release remote. He has released the plans for two versions; a single sided hand etched one, and a double sided one to have made professionally. He notes that it should have a range of at least 10 meters thanks to the 100mAh Li-Po battery and a reasonably high power IR LED. You can download the source code as well as the etching mask and eagle files from the wiki page. He does note that you may have to change the pattern sent to match your camera.
If you’ve been keeping up with our featured stories this year you’ll remember the post about using your own eyelids as 3D shutter glasses. Throngs of commenters called this one as fake and they were right. But we still enjoyed the experience… it’s more fun to be trolled when the trolls are skilled and idea is original. The perpetrators have released a follow-up video that shows how it was done. It’s not just an electronic trinket and some acting. There’s well executed post-production which maps out the area around this gentleman’s eyes and edits in the rhythmic blinking that made the farce somewhat believable. Check it out after the break.
