Many readers will be familiar with Douglas Englebart’s 1968 so-called “Mother of All Demos”, in which he described many of the devices and technologies we would be using two or …read more

Bridges! We kind of expect them to just be there and do their job, ad infinitum. They are built into the landscape, and we often take them and the routes …read more

Recently [shraiwi] decided to have a bit of good nerdy fun and implement the FAST machine vision algorithm on an ESP32-S3 using its SIMD ISA. This involves using the assembly …read more

We’re big fans of pushing hardware into situations it wasn’t designed for here at Hackaday, but sometimes you’ve got to appreciate a nicely designed gadget doing more or less exactly …read more

In the open source world we are used to software being compiled from source for our particular distro, so while in a few cases an ancient release may still be …read more

There are some devices which achieve electronic immortality, it’s likely that you have used a few of them yourself. The 555 timer of course, or the 741 op-amp. [ElectronicsNotes] is …read more

Recently [Rod Burlamaqui] released the arc-rebar project on GitHub, enabling Intel GPUs to work significantly more efficiently if the system’s mainboard does not support resizable BAR. It does require a …read more

Learning a new natural language can be a daunting proposition at the best of times, with repetition and immersion generally considered to be the best ways to build up not …read more

Infrared (IR) communication technologies are probably one of the most influential, yet also one of the least flashiest. The fact that IR communication tends to be highly directional and often …read more

The Kernel-based Virtual Machine (KVM) allows Linux systems to function as hypervisors without needing any extra software, but VMs created with it don’t behave exactly like real hardware does. Sometimes …read more

[Angus] of Maker’s Muse enjoys combat robotics, in which contenders zip about in an arena, attempting to disable one another with weapons that lift, spin, and smash. He got a …read more

A helicopter blade uses a swash plate and a set of linkages to change the angle of the blades. Not only does it vary the collective pitch to increase or …read more

In the world of silicon semiconductors, the process of creating transistors and similar structures involves various rounds of modifications and additions in order to create the requisite functional layers. A …read more

Some disappointing, but perhaps not entirely unsurprising news this week out of Denmark — after announcing last year that they would transition away from Microsoft’s proprietary software, the realities of …read more

With the topic of marble clocks having been quite well explored at this point, it raises the question of how easy it would be to take the basic principle and …read more

Telephony is a bit of a mixed bag. On the one hand, being able to talk to people in far off places is kind of neat, at least in theory. …read more

Some of the first remote controls available to consumers used sound, visible light, or even just wires to communicate with their parent device. It was many years between these first …read more
