For those of us who remember old ball mice, they were a lot like modern optical mice except that they needed to be cleaned constantly. Having optical mice as a …read more Continue reading Smart Ruler Has Many Features
Digitizing an object usually means firing up a CAD program and keeping the calipers handy, or using a 3D scanner to create a point cloud representing an object’s surfaces. [Dzl] took an entirely different approach with his DIY manual 3D digitizer, a laser-cut and 3D printed assembly that uses rotary encoders to create a turntable with an articulated “probe arm” attached.
Each joint of the arm is also an encoder, and by reading the encoder values and applying a bit of trigonometry, the relative position of the arm’s tip can be known at all times. Manually moving the tip of …read more

Usually, with Circuit VR we look at some circuit in detail with simulation — usually LTSpice. This one will be a little meta because I wanted to look at a capability in LTSpice which ironically is very useful, but not often used. Along the way, though, we’ll look at why you get maximum power transfer when your source impedance matches your load impedance. This is something you probably already know about, but it is interesting to look at in simulation if you know how to coax LTSpice — no pun intended — into showing you a meaningful graph.
The circuit …read more
Effectively connect people, process and technology to minimize MTTD and MTTR There’s a reason it’s said that what gets measured gets managed. In order to successfully achieve a goal, you have to be able to measure progress. It’s the o… Continue reading What You Should Know About Driving Down MTTD and MTTR
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
Building a successful audit analytics program is like climbing a staircase. The staircase is a set of steps that consist of several items having increasing levels of maturity. The staircase steps not only help you build your program, but enable …… Continue reading The Analytic Staircase for Auditors
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
“Measure twice, cut once” is great advice in every aspect of fabrication, but perhaps nowhere is it more important than when building a CNC machine. When precision is the name of the game, you need measuring tools that will give you repeatable results and preferably won’t cost a fortune. That’s the idea behind this Arduino-based measuring jig for fabricating parts for a CNC build.
When it comes to building on the cheap, nobody holds a candle to [HomoFaciens]. We’ve seen his garbage can CNC build and encoders from e-waste and tin cans, all of which gave surprisingly good results despite …read more

How do you test the oscillator circuit you just made that runs between 200MHz and 380MHz if all you have is a 100MHz oscilloscope, a few multimeters and a DC power supply? One answer is to put away the oscilloscope and use the rest along with a length of wire instead. Form the wire into a Lecher line.
That’s just what I did when I wanted to test my oscillator circuit based around the Mini-Circuits POS-400+ voltage controlled oscillator chip (PDF). I wasn’t going for precision, just verification that the chip works and that my circuit can adjust the frequency. …read more
