Machinist’s Accuracy vs. Woodworker’s Precision
There are at least two ways of making parts that fit together exactly. The first way is the Cartesian way, and the machinists way. Imagine that you could specify the …read more Continue reading Machinist’s Accuracy vs. Woodworker’s Precision
How To Reverse Engineer Mechanical Designs for 3D Modeling
If you’re interested in 3D printing or CNC milling — or really any kind of fabrication — then duplicating or interfacing with an existing part is probably on your to-do list. The ability to print replacement parts when something breaks is often one of the top selling points of 3D printing. Want some proof? Just take a look at what people made for our Repairs You Can Print contest.
Of course, to do that you need to be able to make an accurate 3D model of the replacement part. That’s fairly straightforward if the part has simple geometry made up …read more

All Security is Cybersecurity
Personal data is collected and used than ever before and in an incredibly diverse number of ways. Traditionally, government and employer ERP systems held our Social Security Numbers, an insurance company database had medical information, and scattered … Continue reading All Security is Cybersecurity
Measure Your Cloud Security in 5 Steps
Our world is obsessed with measurement, and I blame Moneyball. Once it became a bestseller, everyone wanted to use statistics to evaluate everything. How bad is your mother-in-law? Well she scored <6.7 in nine different categories related to emotio… Continue reading Measure Your Cloud Security in 5 Steps
Precision Pantograph Probes PCBs
Electronic components are getting smaller and for most of us, our eyesight is getting worse. When [Kurt] started using a microscope to get a better view of his work, he realized he needed another tool to give his hands the same kind of precision. That tool didn’t exist so he built it.
The PantoProbe is a pantograph mechanism meant to guide a probe for reaching the tiny pads of his SMT components. He reports that he has no longer has any trouble differentiating pins 0.5 mm apart which is the diameter of the graphite sticks in our favorite mechanical pencils. …read more
