Have you ever wished you could experiment with different layouts super easily, just by adding or removing a few switches here and there and printing a new case? Well, [heyisjambo] says that it’s more than possible with menura, the modular keyboard system. So many lovely options! Image by [heyisjambo] via GitHub [heyisjambo] is happy with […]
Many decades ago, when soldering was an activity more often associted with copper fabrication than with electronics, a soldering iron would have been a large lump of copper on a shaft, with a wooden handle. You would heat it in a gas flame, and use its pointed end for your soldering. Electric irons have made […]
The Universal Serial Bus. The one bus to rule them all. It brought peace and stability to the world of computer peripherals. No more would Apple and PC users have to buy their own special keyboards, mice, and printers. No more would computers sprout different ports for different types of hardware. USB was fast enough and […]
It isn’t that hard to make an electronic rain gauge if you have a steady source of power or you don’t mind changing batteries often. But [Matthew Ford] offers a third option: a simple device with a Bluetooth Low Energy (BLE) module that can get a few years of a pair of AA batteries. The […]
The [Denki Otaku] YouTube channel took a look recently at some stepper motors, or ‘stepping motors’ as they’re called in Japanese. Using a 2-phase stepper motor as an example, the stepper motor is taken apart and its components explained. Next a primer on the types and the ways of driving stepper motors is given, providing […]
This unusual tattoo hack by [Emily The Engineer] is not for the weak of heart, but let’s be frank: we kind of know her for that. And she gives out a warning, albeit at a good 10 minutes in, to not do this at home. What she’s about to do takes creativity and tech obsession […]
In his most recent article, [Ken Shirriff] takes a break from putting ASICs under a microscope, and instead does the same in a proverbial manner with the word ‘mainframe’. Although these days the word ‘mainframe’ brings to mind a lumbering behemoth of a system that probably handles things like finances and other business things, but […]
Is fire conductive? As ridiculous that may sound at first glance, from a physics perspective the rapid oxidation process we call ‘fire’ produces a lot of substances that can reduce the electrical insulating (dielectric) properties of air. Is this change enough to allow for significant current to pass? To test this, [The Action Lab] on […]
