With how cheap they’re getting, everyone seems to be jumping on the resin printer bandwagon. They may not be able to fully replace your trusty old FDM printer, but for certain jobs, they just can’t be beaten. Sadly though, creating those smooth time-lapse videos of your prints isn’t quite as easy to do as it is on their filament-based counterparts.
Not as easy, perhaps, but not impossible. [Fraens] found a way to make time-lapses on any resin printer, and in a wonderfully hacky way. First, you need to find a smartphone, which shouldn’t be too hard, given how often we all tend to upgrade. [Fraens] recommends replacing the standard camera app on the phone with Open Camera, to prevent it from closing during the long intervals with nothing happening. The camera is triggered by any readily available Bluetooth dongle, which is connected via a simple transistor circuit to an Arduino output. To trigger the shutter, a light-dependent resistor (LDR) is connected to one of the microcontroller’s inputs. The LDR is placed inside the bed of the resin printer — an Anycubic Photon in this case — where light from the UV panel used to cross-link the resin can fall on it. A simple bit of Arduino code triggers the Bluetooth dongle at the right moment, capturing a series of stills which are later stitched together using DaVinci Resolve.
The short video below shows the results, which look pretty good to us. There are other ways to do this, of course, but we find the simplicity of this method pleasing.
Camera shutter speed is an essential adjustment in photography – along with the aperture, the shutter moderates the amount of light entering the camera. Older cameras (and some newer ones) use mechanical shutters that creep out-of-spec over the years, so [Dean Segovis] built a handy shutter speed tester.
With just a handful of basic components, this project is a great one for beginners to sink their teeth into. The tester is based around a photoresistor that measures light from another source (a flashlight) that travels through the camera body. When the shutter on the camera is released, the shutter speed can be measured and displayed on the OLED screen. An Arduino naturally handles all the computational duties. The whole thing can be easily assembled on a breadboard in just a couple of minutes.
The original project by [hiroshootsfilm] is over on Project Hub, however [Dean] takes a deeper dive with some code troubleshooting, as well as trying out a variety of old film cameras with the breadboard tester. His testing revealed that the photoresistor was better able to detect shutter speed when the camera lens was removed, which is a hot tip for anyone else that wants to try this.
While it’s not surprising that these older cameras are having trouble with their mechanical shutters, this little tester would be an invaluable tool when it comes time to start tweaking shutter mechanisms. The full video is after the break and more details are scribbled down here, but make sure to check out the follow-up video where [Dean] prints a neat enclosure for the electronics.
If your favorite person has a love of video or photography, a camera may be the best gift they’ll ever get. Some may want to capture their adventures with an action camera, while others may desire a mirrorless camera for portraits, movies or artistic shots. The technology is better than ever as camera makers try to stay ahead of smartphones with faster shooting speeds, sharper video and incredible autofocus. We found the best models for budgets ranging from $400 to $2,500, along with top accessories to complement their existing gear.
GoPro Hero 10 Black
Will Lipman Photography for Engadget
For the adventurer on your gift list, there’s no better action camera than the GoPro Hero 10 Black. It bests the previous Hero 9 Black model in a number of key ways, thanks mainly to the faster GP2 processor. That helps it deliver improved image quality, with higher resolution at up to 5.3K/30fps instead of 5K as before. It also offers improved noise reduction, smoother stabilization, more faithful color reproduction and better handling.
Sony’s A6100 is a great gift idea for budding photographers, as it offers the best features of its APS-C mirrorless camera series at the best price. Chief among those is the incredibly reliable autofocus system with eye-detection and other AI tricks. Even with fast-moving action, the A6100 will nail focus for video or photos most of the time thanks to the extremely rapid tracking system. It also offers accurate colors, good low-light performance and a flip-up display that allows for selfies and vlogging, with sharp video capture at up to 4K. It’s also one of the best mirrorless camera deals around at $748, or $848 with a 16-50mm kit lens.
A gimbal is a great gift idea for video shooters, helping them boost production value with smooth tracking, panning and other shots. If your loved one has a mirrorless camera, the best option is DJI’s Ronin-SC model. It weighs just 2.4 pounds, 41 percent lighter than DJI’s original Ronin-S — making it easier to use for longer periods. It can stabilize just about any type of video as well, thanks to the ActiveTrack 3.0 mode and AI that can lock onto and track human or other subjects.
If your gift recipient is into making YouTube videos, the Panasonic GH5 has been the vlogging camera of choice since it first came out . The 20-megapixel Micro Four Thirds sensor delivers pin-sharp 4K video downsampled from the full sensor at up to 60fps, with a 10-bit high-color option that makes editing easier afterwards. It also includes other necessities for vlogging like a flip-out display, in-body stabilization and dual high-speed card slots. With the arrival of the $1,700 GH5 II, the original GH5 is cheaper than it’s ever been at $1,300, giving your loved one a lot of camera for the money.
If your giftee is starting to get serious about video, the Magnus VT 4000 is the best budget tripod option out there. It’s lightweight at 8 pounds, but the anodized aluminum construction is strong enough to handle a mirrorless camera and accessories weighing up to 8.8 pounds. The lack of heft makes it practical for travel, while the fluid head allows for smooth tilts and pans. Other features include a middle spreader to keep things steady and legs that extend up to 64 inches so you can match the eyeline of your subjects.
For a serious camera gift that’s around $2,500, Canon’s 20-megapixel EOS R6 is the best hybrid model out there. It delivers up to 20 fps burst shooting speeds while the Dual Pixel AF nails focus on nearly every shot, whether in bright sunlight or dim lighting. It’s also a solid pick for video, letting you shoot 4K supersampled video at 60 fps with 10-bit log and HDR options for maximum editing flexibility — again, with Canon’s Dual Pixel AF system that’s second to none. The caveat to that is overheating, which limits use for things like weddings and journalism.
Some of the most useful gifts out there for vloggers are Joby’s famous mini-tripods, and the best one for the money is the GorillaPod 3K. Attaching your camera using the secure clip-in mounting plate is dead simple, and you can ensure that everything is even with the built-in level. The flexible legs let you set your camera anywhere to shoot or even wrap it around a tree or other object. The most common usage is as a vlogging handle, as vloggers can bend the legs forward to fit themselves into the video and steady out their shooting.
Your favorite camera nerd can never have enough memory cards, but they can be a pretty pricey gift. SanDisk’s ExtremePro UHS-I SD cards are cheaper than UHS-II cards, but the 90 MB/s read/write speeds are fast enough for most types of photography and video. If your loved one needs that extra UHS-II speed, Lexar’s UHS-II SD 1667X (250MB/s) and 2000X (300MB/s) SD cards are solid picks.
If the vlogger in your life doesn’t already have one, Rode’s wireless and shotgun microphones are solid, affordable gifts. The VideoMic Go is ideal for interviews and run-and-gun shooting, thanks to the crisp directional audio and relative ease of use. It comes with a shock mount to eliminate bumps or vibrations that could interfere with sound and doesn’t require a battery, unlike past Rode models. Meanwhile, Rode’s Wireless Go is one of the most popular wireless lavalier mics out there, functioning as both a microphone and wireless transceiver. It offers a reliable connection and good audio quality, or you can maximize clarity by connecting an external 3.5mm microphone like Rode’s $40 SmartLav+, the Sennheiser Pro Audio ME2 or others.
A good light is an awesome tool in your favorite photographer or videographer’s arsenal, and a relatively affordable gift to boot. One of the best all-around models is the Nanlite LitoLite 5C RGBWW Mini LED Panel. It weighs just 4.8 ounces, but offers dimmable lighting across a range of colors, with adjustments either on the fixture or via a smartphone app. It mounts on any wall or light stand via a magnet or quarter-inch threads, has cordless operation and a battery that runs for 1.5 hours at full power (charged via USB). The most interesting feature is special effects that range from a cop car’s flashing lights, flames, candlelights, a lightning storm and more.
Backpacks are life for photographers and video shooters, so they make great gifts — if you get the right one. Peak Design’s Everyday Backpack 20L is a good choice, thanks to the stylish weatherproof design, internal dividers for laptops, cameras, lenses and more, a wrap-around zipper and a protected laptop sleeve. It offers excellent build quality and Peak Design backs that up with a lifetime warranty.
As someone who used to use Adobe’s Premiere Pro CC exclusively, I never thought I’d switch to another app. I did, though, and can’t recommend Blackmagic Design’s DaVinci Resolve 17.2 enough (either the free or $295 studio version). You get a lifetime of updates, so it’s far cheaper than Adobe’s subscription program that runs $630 per year. Resolve is slightly trickier to learn, but far more powerful than Premiere for key tasks like color grading and effects. Most importantly, I’ve found Resolve to be far, far more reliable than Premiere on a wide range of computers, which is easily the most important “feature” on an editing app.
There’s an old joke where you ask someone what’s the most important thing about comedy. When they get to about the word “important,” you interrupt them and say, “Timing!” Perhaps the same thing can be said for photography. [Ted Kinsman’s] students at the Rochester Institute of Technology would probably agree. They built an Arduino-based rig to do inexpensive stop action photography.
As Arduino projects go, it isn’t very sophisticated. The circuit contains a sound detection module and an optoisolator. The code would easily fit on a piece of notebook paper. When a loud sound occurs, the Arduino triggers the flash. Simple enough, but the resulting pictures are amazing. It also looks like a lot of fun to destroy perfectly good things in the name of art.
If you are interested in photography, there are enough photos of their setup to give you some ideas about lighting, reflectors, and camera angles. If you are not a photography fan, you still should check out the post to see more of the pictures the students took.
Interestingly, [Dr. Harold Edgerton] at MIT pioneered this technique starting back in 1937 and you’ve probably seen some of his famous photographs like the bullet through the apple or the milk drop crown. He used the same techniques to take photographs of the atomic bomb tests in the 1950s and 1960s.
You don’t have to use sound as a trigger, by the way. We’ve seen lasers do the trick. And while the Rochester group’s build was simple, we’ve seen some even more bare-bones.
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 you know. [Jeremy] decided to pair an Arduino Nano with the ISD1820 voice playback module. This was then combined with a servo-based panning fixture – [Jeremy] wants the GoPro to pan, take a photo, and repeat. The Arduino sets the servo position, then commands the ISD1820 to playback the voice command to take a picture, before rotating again.
[Jeremy] reports that it’s just a prototype at this stage, and works only inconsistently. This could perhaps be an issue of intelligibility of the recorded speech, or perhaps a volume issue. It’s hard to argue that a voice control system will ever be as robust as remote controlling a camera over WiFi, but it just goes to show – there’s never just one way to get the job done. We’ve seen people go deeper into GoPro hacking though – check out this comprehensive guide on how to pwn your GoPro.
If you’ve ever seen a TV commercial for any fast-food chain, then chances are you’re familiar with the burger drop shot–you know, that scene where ingredients like lettuce, tomatoes, onions, bacon, beef patties and sesame seed buns fall from above and then stack themselves upon landing. Well, photographer/Maker Steve Giralt wanted to try capturing a shot like this on his own without the use of CGI or an expensive post-production process.
To accomplish this, Giralt created a rig with an Arduino-based timing control system (named P.A.T.R.I.C) that triggers the camera motion, as well as the drop of the burger’s ingredients so that everything falls perfectly.
As he explains:
The final video is a synchronized work of art. In the half second of real time, multiple Arduino controlled servo motors with custom 3D printed scalpel blades cut through elastic bands holding up the top bun, pickles, onions, lettuce, tomato, bacon, meat, and lower bun while a 3D printed air powered catapult launched ketchup and mustard blobs into each other.
This all happened while the Phantom camera was moving down on the motion control robot arm at high speed, adjusting focus, as it raced the ingredients and gravity down to the landing.
When we got a perfect landing of the burger, I had a hand model slam down a freshly poured beer down next to the burger to finish off the shot. It was so much fun!
