You want to join two shafts. What do you need? A coupler, of course. If the shafts don’t line up, you might consider an Oldham coupler. But what if the …read more Continue reading A Hobson’s Coupler Leads to a Weird Engine
The discovery and implementation of alternating current revolutionized the entire world little more than a century ago. Without it, we’d all have inefficient, small neighborhood power plants sending direct current …read more Continue reading Siphoning Energy From Power Lines
It’s a rare person who can pick up a cheap laser pointer and not wield it like a lightsaber or a phaser, complete with sound effects. There’s just something about …read more Continue reading Properly Pipe Laser Light Around with Homebrew Fiber Couplings
In our vernacular, bricking something is almost never good. It implies that something has gone very wrong indeed, and that your once-useful and likely expensive widget is now about as useful as a brick. Given their importance to civilization, that seems somewhat unfair to bricks, but it gets the point …read more
Interfacing a shaft to a 3D printed gear doesn’t have to be tricky.

The picture above (and this older link) shows everything you need to know: the bottom of …read more
