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 …read more Continue reading The Case Against Calibration Cubes
If there’s anything more viscerally pleasing than seeing an eight-digit instrument showing a measurement with all zeroes after the decimal point, we’re not sure what it could. Maybe rolling the …read more Continue reading Upgrade Puts a Lot of Zeroes on Kit-Built Frequency Counter
Ah, the beloved Commodore 64. The “best-selling computer system of all time”. And hobbyists are keeping the dream alive, still producing software for it today. Which leads us to a …read more Continue reading Commodore Datasette Does Its Own Calibration
3D printing bearings with an FDM printer can be an iffy endeavor, but it doesn’t have to be that way. [Matvey Kukuy]’s Ultimate 608 Bearing with Calibration Kit is everything …read more Continue reading 3D Printable Bearings That Actually Work, No CAD Tweaking Required
For prototype electronics projects, most of us have a pile of resistors of various values stored somewhere on our tool bench. There are different methods of organizing them for easy …read more Continue reading Programmable Resistance Box
Necessity might be the mother of all invention, but we often find that inventions around here are just as often driven by expensive off-the-shelf parts and a lack of willingness …read more Continue reading Pressure Gauge Built In A Vacuum
Among his many interests, [Dave Jones] likes test and measurement equipment. He recently posted a few videos on his EEVblog exploring the reasons why Fluke voltmeters are so expensive. In the …read more Continue reading Fluke DMM Hack Adds One Digit to Model Number
Laser cutters and 3D printers are game-changing tools to have in the workshop. They make rapid prototyping or repairs to existing projects a breeze as they can churn out new …read more Continue reading Laser Z-Axis Table Comes Into Focus
We’re always a fan of an interesting or unique clock build around here, which often use intricate pieces of technology to keep time such as weights and gears, crystal oscillators, …read more Continue reading Precise Sundial Tells Time to the Minute
Those of us who have bought cheap TinyVNA devices for our RF experimentation will be used to the calibration procedure involving short-circuit, 50 Ω, and open terminations, followed by a …read more Continue reading Calibrating a VNA The Proper Way
