Want to add a degree motion to your GoPro camera without a bulky gimbal? If so, here’s a simple DIY add-on for your multicopter that may only take you a couple minutes to build.
All you’ll need is a spare servo, a 25mm M5 bolt with nyloc nut (for GoPro mount), some double sided foam tape or equivalent, and some other small vitamins.

It’s a simple idea. Just modify the source code from our Arduino IP Webcam project page and add an additional set of AJAX response lines that toggle a couple IO pins on the Arduino. You can have these pins go directly to some headers on your 3D printer and/or to an inline power-switch tail that you can toggle in the event of a problem. All the while monitoring your 3D printer visually with a live image feed from anywhere on the World Wide Web.
Heck, while you’re at it, you might as well add some remote controlled lighting, and a relay shield. Your only limit is
your imagination RAM. Check out this simple user interface:

Over these past few months, I have slowly been testing out various materials for absorbing vibrations in the Revision III tricopter. The goal was to eliminate the rolling-shutter effect (or jello-effect) from aerial video as much as possible.
If you don’t already know, this tricopter has its battery and camera equipment suspended from the main frame with three zip-ties. Dampening materiel is loosely compressed or adheared between these two subassemblies and is ultimately responsible for most of the physical vibration isolation. Usually this materiel is rolled into three separate ~1″ long by ~5/8″ wide cylinders and stuck between each of the three zip-tie loops.
Among the materials I have tested include vinyl furniture bumpons, Sugru blocks, double sided foam (vinyl) adhesive, and latex foams among other things. Most worked pretty well, but others were hard to come by or showed poor performance.
Here is a short list of my findings presented in a general order with the best (so far) near the top. Continue reading Obscure vibration dampener material tests for the Rev. III Tricopter
