Giant Bearing Is At The Heart Of A Camera Mount

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.

Microscope DSLR Mount Using PVC & Heat

Microscopes are a great way to see the mysteries of the universe hidden at the smaller scale. When they were first developed, scientists had to rely on illustration to convey their findings through the lens. Thankfully we can  now rely on photography to help us out instead. Many microscopes come with a special port — often called a trinocular port — for mounting a camera. Using this, [Brian] developed a DSLR mount for his microscope using a hacker staple: PVC pipe.

squareThe virtues of PVC pipe are many and varied. It’s readily available in all manner of shapes and sizes, and there’s a wide variety of couplers, adapters, solvents and glues to go with it. Best of all, you can heat it to a point where it becomes soft and pliable, allowing one to get a custom fit where necessary. [Brian] demonstrates this in using a heat gun to warm up a reducer to friction fit the DSLR lens mount. Beyond that, the mount uses a pair of lenses sourced from jeweller’s loupes to bring the image into focus on the camera’s sensor, mounted tidily inside the PVC couplers.

PVC’s a great way to quickly and easily put a project together — so much so that there are fittings available specifically for using PVC to build stuff. Video below the break.
