Elegant, functional mechanical models don’t need to be large. In their “LEGO Technic Micro Stepper Mechanism” video, Lego Technic Mastery demonstrates how to build a simple, manually-operated stepper motor that can attach to any Technic beam. This stepper machine has four 90° stops, allowing for precise quarter turns in both the clockwise and counter-clockwise direction.
At 0:56 in the video, Lego Technic Mastery provides a shot of all the parts needed for this mcahine plus step-by-step instructions. I followed the instructions and built my own “little stepper” with little difficulty (although I did break a LEGO rubber band in the process).

If conversations about audio equipment have you fondly remembering terms like “45 rpm”, “B-side”, “mix tape” or “VHF” then you’re probably ancient like me. Or you just rented Guardians of the Galaxy. Either way, this LEGO trifecta of vintage gear is far out, right on, and out of sight… Can you dig it?
First up is this 70s kitchen scene from Swedish retro-fanatic LegoJalex, featuring a portable radio and a color palette that practically defined the home décor of that decade. Looks like something right out of the 1973 IKEA catalog (and strangely, the 2010 catalog). It’s groovy, man.
Next, are these super-accurate recreations of turntable / cassette player units from the same era, created by Indonesian builder Yul Burman Karel. I swear, the one on the left looks like the exact one I used as a kid. Ok, time to boogie!
Since creating the air hockey table we featured a while ago, Turkish builder Sinan Bitişik has taken to accurately reproducing all manner of real-world machines using LEGO, including a weed wacker, record player, road paver, AC unit and even an oven. But I particularly love the attention to detail in his latest piece, a brick-built lat machine…
…of course, it’s crying out for a Miniland scale body builder to put it through its paces!
