We bet you have all some cool part in your bin that is just gnawing at you to build something cool. That doodad, possibly from a garage sale, surplus store, or clearance rack deserves a project fitting of its near-infinite potential. [isaac879] finally marries a giant ball bearing with his passion for photography in the form of a pan-tilt camera mount for his Canon DSLR. The problem with tossing your golden-ticket part into a project is that not everyone has a MacGuffin, or a brand new one might be bank-breakingly expensive, so he does us a favor and makes a drop-in replacement that you can print and fill with 6mm brass bbs. This sort of thing is why we love hackers.
The camera mount has the features we expect to see in a robust stepper mount, such as infinite spinning, time delay, and an Xbox controller interface. Inside the base is the industrial bearing or its plastic replica, and that wide base won’t be tipping over anytime soon. Gearing all around is of the herringbone style, of the type you find in classroom pencil sharpeners because they transfer power smoothly. Speaking of things going smoothly, we enjoyed his assembly montage where every part fits together perfectly and there is not a naughty word to be uttered. Just like real life.
If you like homemade bearings, check out this slew bearing that looks like it was made with Perler beads, and we have a self-aligning camera tripod mount for the photography buffs.

When working with cameras or other tools, it can often be useful to have some manner of stand or tripod to hold things in position, freeing up one’s hands for other tasks. Unfortunately, when it comes to smaller cameras and devices like smartphones and tablets, there are few standardized solutions. [yyh1002] has skirted the problem by creating a customizable modular mounting system, and it’s taken the 3D-printing world by storm.
The system was inspired by GoPro mounts, which are a system of plastic arms and screws that can effectively position the small devices in all manner of orientations. [yyh1002]’s system is GoPro-compatible, using the same fasteners and similar geometry, and tons of other modelers have added on.
The parts are 3D printed and consist of a series of arms, clamps and joints that can be configured to suit the task at hand. Source files are available, which allows custom version to be made. This is useful for modifying parts like phone holders to suit different models, to avoid fouling buttons or interfering with camera placement. Thus far, the community has contributed parts as diverse as G-clamps, camera mounts, and parts to mate to Playstation controllers. (Editor’s note: I’m actually printing out a Pi Zero case from this series as I edit this post. Coincidence!)
It’s a useful system, and we look forward to seeing more parts uploaded in future. Meanwhile, don’t forget – it’s remarkably easy to tripod mount just about anything.
[Enginoor] is on a quest. He wants to get into the world of 3D printing, but isn’t content to run off little toys and trinkets. If he’s going to print something, he wants it to be something practical and ideally be something he couldn’t have made quickly and easily with more traditional methods. Accordingly, he’s come out the gate with a fairly strong showing: a magnetic Maxwell kinematic coupling camera mount.
If you only recognized some of those terms, don’t feel bad. Named for its creator James Clerk Maxwell who came up with the design in 1871, the Maxwell kinematic coupling is self-orienting connection that lends itself to applications that need a positive connection while still being quick and easy to remove. Certainly that sounds like a good way to stick a camera on a tripod to us.
But the Maxwell design, which consists of three groves and matching hemispheres, is only half of the equation. It allows [enginoor] to accurately and repeatably line the camera up, but it doesn’t have any holding power of its own. That’s where the magnets come in. By designing pockets into both parts, he was able to install strong magnets in the mating faces. This gives the mount a satisfying “snap” when attaching that he trusts it enough to hold his Canon EOS 70D and lens.
[enginoor] says he could have made the holes a bit tighter for the magnets (thereby skipping the glue he’s using currently), but otherwise his first 3D printed design was a complete success. He sent this one off to Shapeways to be printed, but in the future he’s considering taking the reins himself if he can keep coming up with ideas worth committing to plastic.
Of course we’ve seen plenty of magnetic camera mounts in the past, but we really like the self-aligning aspect of this design. It definitely seems to fit the criterion for something that would otherwise have been difficult to fabricate if not for 3D printing.
The workbench of the typical electronics hobbyist today would probably be largely recognizable by Heathkit builders back in the 60s and 70s. But where the techs and tinkerers of yesteryear would have had a real dead-tree SAMS Photofact schematic spread out on the bench, today you’ll get more use out of a flat-screen display for data sheets and schematics, and this handy shop Frankentablet might be just the thing to build.
Tablets like the older Nexus 9 that [enginoor] used as the basis for this build have a little bit of a form-factor problem because unlike a laptop, a tablet isn’t very good at standing up on its own. To fix that, they found a suitable silicone skin for the Nexus, and with some silicone adhesive began bedazzling the back of the tablet. A bendy tripod intended for phones was added, and with the tablet able to stand on its own they maximized the USB port with a right angle adapter and a hub. Now the tablet has a USB drive, a mouse, and a keyboard, ready for perusing data sheets online. And hackers of a certain age will appreciate the eyeball-enhancing potential of the attached USB microscope.
[enginoor]’s bench tablet is great, but we’ve seen full-fledged bench PCs before too. Take your pick — wall mounted and floating, or built right into the workbench.
Thanks to [ccvi] for the tip.
[Punamenon2] wanted a soldering station with integrated helping hands. He couldn’t find one, but he decided it would be a good 3D printed project. In all fairness, this is really 3D printing integrating several off-the-shelf components including a magnifier, a soldering iron holder, a soldering iron cleaner, a couple of “octopus” tripods, and some alligator clips. Total cost? Less than $30.
In addition to holding the Frankenstein monster together, the 3D printed structure also provides a storage tray with special sloped edges to make removing small screws easier.

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?
