Having watched some fun videos on repurposed satellite dishes on YouTube, [Melan] wanted to get in on the action. She managed to source herself an Intellian i4, a dish built …read more

Airborne micro particles can be a significant health hazard in a workshop, and thus it’s important to maintain a high standard of ventilation. But monitoring their concentration is also important, …read more

If we care to cast an eye over the history of ubiquitous personal computing as we know it today, we might immediately point at the original IBM PC. After all, …read more

The humble credit card reader — most of us have used hundreds, perhaps even thousands of them over the years. But even for folks like us, it’s not the sort …read more

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
