The next giant leap for mankind is to the stars. While we are mostly earthbound — for now — that shouldn’t stop us from gazing upwards to marvel at the night sky. In saying that, if you’re an amateur astrophotographer looking to take long-exposure photos of the Milky Way and other stellar scenes, [Anthony Urbano] has devised a portable tracking setup to keep your photos on point.
When taking pictures of the night sky, the earth’s rotation will cause light trails during long exposures. Designed for ultra-portability, [Urbano’s] rig uses an Arduino UNO controlled Sanryusha P43G geared stepper motor coupled to a camera mounting plate on a small tripod. The setup isn’t designed for anything larger than a DSLR, but is still capable of taking some stellar pictures.

[Hackett] calls it a “transmission problem.” You’ve scavenged the pieces for your build, but nothing fits. Metric and standard hardware clash, a successful weld is as reliable as duct-taping. You’ll hear about plenty of these obstacles as [Hackett] tries to tackle a tripod build in this video.
He was contacted by a group looking to make a bicycle-mounted portable projector. Their request: build them an easy-to-use tripod on a shoestring budget that is strong enough to hold a 30-pound projector. Garbage and scrap turn into a functional device as [Hackett] grinds and welds the tripod together.
The video’s greatest contribution, however, is the advice near the end.
You need to retrain your eye, so you’re not looking at a thing as to what it is, what it’s branded, what it’s originally intended for. What you’re looking at is what it is at the core, and once you start looking at things for what they really, really are, you have the power to completely remake the world.
A desire to re-contextualize everyday stuff is probably the reason you’re a Hackaday reader. Hopefully [Hackett’s] succinct advice strikes some chords and encourages you to keep abstracting and re-purposing the world around you. If you’re new to hacking and need somewhere to start, why not build a robot?

Want to try out aerial photography, but can’t afford a quadcopter? [Jeremy] rigged up a low cost GoPro Slingshot and took some pretty nice flyover shots of the lake.
The slingshot itself is meant for water balloons, but easily has enough power to fire the camera. In order to get good video, some stabilization was needed. [Jeremy] made a stabilizing fin out of packaging foam, and used an eye bolt to connect it to the GoPro’s threaded tripod mount. The simple tail fin made of out foam and zip ties actually did a good job of stabilizing the camera.
This looks like a fun experiment to try when you’re at the lake, since you can probably build it with stuff lying around the house. For [Jeremy], it also proved to be a way to keep his dog entertained since she retrieved the camera after each shot. After the break, check out the video footage from the GoPro slinging rig.

We’re used to seeing hacked camera mounts but [CroBuilder] mentioned to us that nobody is really making plain old tripods themselves. He loves to work in his shop so he spent about ten hours building this tripod for himself.
We’d say it’s built to last, but that comes at the cost of weighing a lot. He used square tubing for the legs, which are tripled up in order to allow them to telescope. Each leg has two pipes mounted to the central hub that he fabricated out of hexagonal pipe. A bolt and wing nut acts as hinge and clamp. On the bottom section of the leg there’s a tab spanning the two pieces and another clamping mechanism to hold the adjustable bottom portion of the leg in position.
He finished up the project with black paint on many of the pieces, with the legs themselves polished until shiny. Will rust be a problem if he doesn’t use a clear coat?
The nice thing about a quality tripod is that you can use them for more than just cameras. For instance, add some components to make your own laser level.
[Shawn] wrote in to tell us about his extremely simple method he used for mounting a webcam on a tripod. His article explains it better, but the basic premise is to glue a 1/4 – 20 nut onto the bottom of it. The hack-worthiness of this could be in question, but the technique could come in handy at some point.
After seeing this tip, I was reminded of a slightly crazier, if effective mount that I made for my
state of the art Env2 phone. Referenced in a links post in March, it was made of a 2×4 with a 1/2 inch slot milled in it. After some thought, it was drilled and tapped for a 1/4 – 20 bolt in the other side to mount it on a tripod. So this could be an option in very limited circumstances.
On the other hand, if you want something a bit more hack-worthy, why not check out this motorized camera rig that we featured in July. Sure, it’s more complicated than gluing a nut onto a webcam, but at least it still uses 2 x 4s in it’s mounting hardware!
Where some people might see a pile of junk, Hackaday reader and budget-conscious photo nut [FantomFotographer] sees inspiration. He was in search of a rig that would help him take better panoramic photos and found all that he needed to build one right around him.
He had an old tripod kicking around, which serves as the base for rig. At the top sits a pair of servos [FantomFotographer] attached to the tripod with some scrap wood, screws, and glue. The servos are driven by an Arduino Nano, which sits comfortably in a plastic enclosure he scavenged from trash heap. He uses an IR receiver to control the whole thing, which allows him to not only change shooting angles, but camera settings as well.
While it might sound like all is well with his upcycled camera rig, [FantomFotographer] says that like every project, there is some room for improvement. He’s keeping the source code under wraps at the moment, but once he gets everything working to his liking, he says that he’ll release it.
In the meantime, be sure to check out the cool panoramas he has put together.
It looks like [Renate] has been pounding out hack after hack on her Nook touch. It stands on its own now thanks to a tripod bracket hack which is the most recent work she’s done. But there are bunch of other modifications, all of which are linked after the break.
We believe that this is meant for displaying lyrics as she sings and plays along. To that end there’s a foot pedal attachment that lets her control the device. It connects to the Nook via a USB hub that allows her to interface multiple devices at once. This in itself is also a hack, as host mode isn’t an out-of-the-box feature for the device. In order to avoid having to disconnect everything in order to top off the battery, she also manged to get the thing to charge from the USB hub. In fact, with all this in one package she’s basically got herself a desktop computer.
