Sometimes, when making a 3D printed object, plastic just isn’t enough. Probably the most common addition to our prints is the ubiquitous brass threaded inset, which has proven its worth time and again over the years in providing a secure screw attachment point with less hassle than a captive nut. Of course to insert these […]
Until recently, hobby-grade digital oscilloscopes were mostly, at most, 8-bit sampling. However, newer devices offer 12-bit conversion. Does it matter? Depends. [Kiss Analog] shows where a 12-bit scope may outperform an 8-bit one. It may seem obvious, of course. When you store data in 8-bit resolution and zoom in on it, you simply have less […]
Saleae logic analyzers seem to have it all: good sampling rates, convenient protocol decoding, and plenty of channels – but not a good way to set rising or falling-edge triggering. [James] found this rather inconvenient when debugging embedded devices, and shared a workaround that replicates these simple triggering modes. Crucially, the logic analyzer’s software has […]
Stripping and cutting wires can be a tedious and repetitive part of your project. To save time in this regard, [Red] built an automatic stripper and cutter to do the tiring work for him. An ESP32 runs the show in this build. Via a set of A4988 stepper motor drivers, it controls two NEMA 17 […]
The modern hacker and maker has a truly incredible arsenal of tools at their disposal. High-tech tools like 3D printers, laser cutters, and CNC routers have all become commonplace, and combined with old standbys like the drill press and mini lathe, it sometimes seems like we’ve finally peaked in terms of what the individual is […]
If you want a regular table saw, you’re probably best off just buying one—it’s hard to beat the economies of scale that benefit the major manufacturers. If you want a teeny one, though, you might like to build it yourself. [Maciej Nowak] has done just that. The concept is simple enough; a small motor and […]
We all know UV radiation for its contributions to getting sunburned after a long day outside, but were you aware there are several types different types of UV rays at play? [Michael] has come up with a Flipper Zero add on board and app to measure these three types of radiation, and explained some of […]
Solder fumes are not nice on the lungs; nor are fumes from superglue, epoxy, or a whole mess of other things we often find ourselves using on the bench. Some people might be able to go the fume hood route to toss that all outside, but for the rest of us, there’s fume extractors. [Raph] […]
For circuit simulation, we have always been enthralled with the Falstad simulator which is a simple, Spice-like simulator that runs in the browser. [Brandon] has a simulator, too, but it simulates semiconductor devices. With help from [Paul Falstad], that simulator also runs in the browser. This simulator takes a little thinking and lets you build […]
