Obscure vibration dampener material tests for the Rev. III Tricopter

isgif2

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

Tricopter Build Log part three

It’s alive! The tricopter went under a few more revisions and prints before finally taking to the air. My old Rev One Quadcopter has been reduced to it’s (over-engineered) frame and nothing more. Its parts (motors, ESCs, batteries, Crius AIO, etc.) have moved on to become this very tricopter.

Currently (in the picture) it is set up to fly FPV sans-GoPro. There is an optional part available to replace the camera pan/tilt servo mount/hole with an alternative “use-what-you-want” vibration-dampened plate.

Keep reading for a couple closeups and highlights of the tricopter.
