[It’s on my MIND] designed a clever BB blaster featuring a four-bar linkage that prints in a single piece and requires no additional hardware. The interesting part is how it turns a trigger pull into ...

That table fan next to you is more interesting than you think! I've taken mine apart to show you how it works. The “four-speed mechanism” releases any other button that was previously pressed. Once a ...

Ever wonder how a tabletop fan moves side to side? A simple 4-bar mechanism, hidden gears, and a clever pin system make it all happen with the push of a button. This video has been dubbed in over 20 ...

The synthesis of four‐bar mechanisms and the generation of precise motion have long been central to advancements in mechanical design. Recent progress has integrated advanced optimisation algorithms, ...
