The Case Against Calibration Cubes

Calibration cubes have long been a staple for testing and adjusting 3D printers, but according to [Stefan] of CNC Kitchen, they’re not just ineffective—they could be leading us astray. In the…

MAUI UPDATE: Pentecostal Church "Cut In Half" By Precision Laser Beam? | WLT Report

I debated whether or not to run this article because there isn’t a lot of mainstream coverage of it (yet), but there are plenty of photos and videos.

Over-the-Top Programmable Resistor Looks The Part And Performs

Every once in a while we get wind of a project that we’re reluctant to write up for the simple reason that it looks too good to be true. Not that projects need to be messy to be authentic, mi…

Learn How Impossibly Close-fitting Parts Are Actually Made

Most of us have seen those demonstrations of metal parts that mate together so finely that, once together, they have no visible seam at all. But how, exactly, is this done? [Steve Mould] has a vide…

Metric And Inch Threads Fight It Out For Ultra-Precise Positioning

When you’re a machinist, your stock in trade is precision, with measurements in the thousandths of your preferred unit being common. But when you’re a diemaker, your precision game need…

The Inner Machinations Of The Arduino Are An Enigma

Arduinos have been the microcontroller platform of choice for nearly two decades now, essentially abstracting away a lot of the setup and lower-level functions of small microcontrollers in favor of…

Animate Arcane Protocols With Interrupt-Backed Bitbanging

We often take our “SoftwareSerial” libraries for granted, and don’t investigate what goes on under the hood — until they fail us, at least. Would you like to learn how to ha…

Time And Accuracy In Las ATMegas

Do you ever have to ensure that an exact amount of time passes between two tasks in your microcontroller code? Do you know what’s the difference between precision and accuracy? Today, [Jim Ma…

Books You Should Read: The Perfectionists

After pulling late hours in my school machine shop for a few years, I couldn’t help but wonder, who measures the measurement tools? How did they come to be? I’d heard anecdotes from oth…

WIST - Vauvenargues, Luc de | Reflections and Maxims [Réflexions et maximes] (1746) [tr. Lee (1903)]

It is of no use to possess a lively wit if it is not of the right proportion: the perfection of a clock is not to go fast, but to be accurate.

Tricky Screw Heads Have Disappearing Slots

Perhaps you’ve seen them, demonstrations of a machined piece of metal that upon further inspection is actually two pieces machined so perfectly that they appear as one. With extremely tight t…

Printable Caliper Jaws Increase Precision, Deflect Derision

If you’ve watched as many machining videos as we have, no doubt you’ve seen someone commit the cardinal sin of metalworking: using caliper jaws to scratch a mark into metal. Even if it&…

Beginning The Machine Shop Journey With A DIY CNC

Building a good quality machine shop may seem to present a chicken-and-egg problem, at least for anyone not willing to mortgage their home for the money needed to buy all of these tools new. Namely…

The Devil Is In The Details

If you’ve taken a physics class, you’ve doubtless heard tales of mythical beasts like the massless string, the frictionless bearing, and the perfect sphere. And if you’re designin…
