[Ryan] wrote in to tell us about his partially 3D-printed steadycam mount on Instructables. In the video after the break, the camera does stay quite steady through some basic tests. The base is a paint roller handle, and the device works by using a long arm on the bottom with some weights to keep the camera upright. This handle is attached to the weights and camera through a 3-axis Gimbal system that allows the camera to stay relatively steady even if your hand isn’t. A full bill of materials and the needed STL files are provided.
Of course if you’re “old school” and like to use subtractive manufacturing methods, you can always check out this [camera stabilizer] from [Do-It-Yourself Gadgets]. The device works in a nearly identical manner, but the BOM seems to be: metal, screws, threaded rod. There are some cool animated GIFs of it in action on the site, or check out the video after the break.
As a “camera mount” bonus, check out this super easy [GoPro] (or any other small camera) clamp mount. Really clever. Continue reading “Make Your Own Steadycam Mount”
Electronics are undoubtedly the basis for our modern society. Leaving out transistor-based devices, and a mechanical clock would be one of the most intricate devices man has come up with. As a Mechanical Engineer, I thought it would be a fun challenge to design and build my own gear-driven clock.
Because clocks have obviously been invented, I wouldn’t be starting from scratch, and I don’t think I could have figured out an escapement on my own. I explain my initial clock escapement and gear reduction design thoughts in this post, and originally getting the escapement to work was my biggest fear.
As seen in the first video after the break, the escapement gear is still a big problem, but not really for the reason I expected. The shaft that the gear sits on seems to be bent, so it allows the escapement to “go free” for part of it’s cycle, losing any sense of accurate timekeeping. Be sure to also check out the second video, especially around 1:50 when I show what happens when an escapement gear goes much faster than a normal clock.
