Valve’s new Steam Frame is what all the well-connected YouTubers are talking about, but most of them are talking about what it’s like to game on it. That’s great content if you’re into it, but not exactly fodder for Hackaday — with one exception. [Gamers Nexus] gives us a half hour of relatively-unedited footage of […]
While most of the world’s venture capital is off chasing anything with “AI” in the name in what many think looks increasingly like an inflated spherical film of soap molecules, in aviation all the hot money is betting on eVTOL: electric vertical take off and landing. What if you want to get in on the […]
Given that we live in the proverbial glass house, we can’t throw stones at [ellis.codes] for modifying a perfectly fine Vornado fan. He’d picked that fan in the first place because, unlike most fans, it had a DC motor. Of course, DC motors are easier to control with a microcontroller, and next thing you know, […]
While you might not know it from their market share, Intel makes some fine GPUs. Putting one in a PC with an AMD processor already feels a bit naughty, but AMD’s x86 processors still ultimately trace their lineage all the way back to Intel’s original 4004. Putting that same Intel GPU into a system with […]
It isn’t unusual to expect a precisely regulated voltage in an electronic project, but what about times when you need a precise current? Over on EDN, prolific [Stephen Woodward] explains how to use a precision Zener diode to get good results. [Stephen] takes you through the math for two topologies and another circuit that uses […]
The 8845 LEGO Technic Dune Buggy original. (Credit: Matt Denton) It’s part of the great circle of life that toys and scale models that provide a reflection of macro-sized objects like vehicles and buildings will eventually be scaled up again to life-sized proportions. Case in point the LEGO Technic dune buggy that [Matt Denton] recently […]
We suspect kids today — and some adults — are confused about phone terminology. In today’s world, “hanging up” and “dialing,” for example, are abstract words without the physical reference that older people remember. But some people have a soft spot for the old rotary dial phones, including [Stavros], who wired a rotary phone to […]
In the days of 8-bit home computing, the more fancy machines had sound chips containing complete synthesizers, while budget machines made do with simple output ports connected to a speaker — if they had anything at all. [Normal User] appears to be chasing the later route, making PCM sound by abusing the serial port on […]
