The most recent undertaking video from Carl Bugeja cleverly combines a number of strategies to create a electrically actuated flexure bearings utilizing supplies and processes obtainable from PCB distributors.

A flexure bearing is part with two inflexible constructions joined by a skinny space that acts as a hinge. For instance, consider a container with an hooked up plastic lid that snaps shut. Bugeja mixed that concept with versatile PCB actuators to supply an electrically-controlled bearing that deforms to generate movement.

As with earlier initiatives, the video paperwork the preliminary design concept, a number of variations, and the necessity for iterations. Initially, Bugeja made 5 totally different flexure designs. A PCB fab manufactured the bearing body, flexure hinge, and adhesive. The one materials Bugeja had so as to add was the magnet.

A number of designs, just like the spring model, had been too fragile to be reliably assembled or used. Nevertheless, what Bugeja calls the “zig-zag design” carried out the very best of the 40 variations examined, which results in the query of what might such a tool do.

Bugeja explored 5 potential functions for the flexure bearing. Essentially the most sensible possibility is a sound technology gadget, which is unsurprising because the whole construction resembles a speaker.

Essentially the most eye-catching try was a pop-up show that emulates a seven-segment show. Sadly, Bugeja encountered issues putting in the magnets, so the video doesn’t present a whole digit as practical. As a substitute, solely two parts had been loaded. Much more unlucky, the consequence was not a flipping mechanism.
