Let’s just kick things off in style with the fabulously brutalist Bayleaf wireless split from [StunningBreadfruit30], shall we? Be sure to check out the wonderful build log/information site as well for the full details. Image by [StunningBreadfruit30] via reddit Here’s the gist: this sexy split grid of beautiful multi-jet fusion (MJF) keycaps sits on top […]
There’s something that kills coding speed—iteration time. If you can smash a function key and run your code, then watch it break, tweak, and smash it again—you’re working fast. But if you have to first compile your code, then plug your hardware in, burn it to the board, and so on… you’re wasting a lot […]
An Instruction Set Architecture (ISA) defines the software interface through which for example a central processor unit (CPU) is controlled. Unlike early computer systems which didn’t define a standard ISA as such, over time the compatibility and portability benefits of having a standard ISA became obvious. But of course the best part about standards is […]
GPS is an incredible piece of modern technology. Not only does it allow for locating objects precisely anywhere on the planet, but it also enables the turn-by-turn directions we take for granted these days — all without needing anything more than a radio receiver and some software to decode the signals constantly being sent down […]
There are all kinds of expensive beauty treatments on the market — various creams, zappy lasers, and fine mists of heavily-refined chemicals. For [Ruth Amos], a $78,000 LED bed had caught her eye, and she wondered if she could recreate the same functionality on the cheap. The concept behind [Ruth]’s build is simple enough. Rather […]
If you’re designing a robot for a specific purpose, you’re probably ordering fresh parts and going with a clean sheet design. If you’re just building for fun though, you can just go with whatever parts you have on hand. That’s how [Sorush Moradisani] approached building Esghati—a “robot made from garbage.” Remote viewing made easy. The […]
If you’re the sort who finds beauty in symmetry – and I’m not talking about your latest PCB layout – then you’ll appreciate this clever take on the long-tailed pair. [Kevin]’s video on this topic explores boosting common mode rejection by swapping out the old-school tail resistor for a current mirror. Yes, the humble current […]
On paper, electricity behaves in easy-to-understand, predictable ways. That’s mostly because the wires on the page have zero resistance and the switching times are actually zero, whereas in real life neither of these things are true. That’s what makes things like switch-mode power supplies (SMPS) difficult to build and troubleshoot. Switching inductors and capacitors tens […]
Braun was once a mighty pillar of industrial design; a true titan of the mid-century era. Many of the company’s finest works have been forgotten outside of coffee table books and vintage shops. [Distracted by Design] wanted to bring one of the classics back to life—the Braun HL70 desk fan. The original was quite a […]
Handy diagnostic LEDs on the side of the tone generator boards. (Credit: Mend it Mark, YouTube) Somehow, an Elka Synthex analog synthesizer made it onto [Mend it Mark]’s repair bench recently. It had a couple of dud buttons, and some keys produced the wrong tone. Remember, this is an analog synthesizer from the 1980s, so […]
