Two weeks ago, it was holographic cops. This week, it’s humanoid robot doctors. Or is it? We’re pretty sure it’s not, as MediBot, supposedly a $10,000 medical robot from Tesla, ap…

Bambu Labs make indisputably excellent printers. However, that excellence comes at the cost of freedom. After a firmware release earlier this year, Bambu printers could only work with Bambu’s…

These days, most of us have a smartphone. They are so commonplace that we rarely stop to consider how amazing they truly are. The open-source project Phyphox has provided easy access to your phone’…

The rotary evaporator (rotovap) rarely appears outside of well-provisioned chemistry labs. That means that despite being a fundamentally simple device, their cost generally puts them out of reach f…

The 1993 Pioneer LaserActive certainly ranks high on the list of obscure video games. It was an odd duck; it used both a LaserDisc for data storage and provided compatibility with a range of existi…

Ever want to find your device on the map? Think we all do sometimes. The technology you’ll generally use for that is called Global Positioning System (GPS) – listening to a flock of sat…

Ultralight aviation provides an excellent pathway for those who want to fly, but don’t want to get licensed. These quite often cheap and cheerful DIY aircraft often hide some excellent engine…

There’s a saying in mine country, the kind that sometimes shows up on bumper stickers: “If it can’t be grown, it has to be mined.” Before mining can ever start, though, there has to be ore in the g…

Although kids these days tend to hang out on so-called “Social Media”, Internet Relay Chat (IRC) was first, by decades. IRC is a real-time communication technology that allows people to…

There’s something uniquely satisfying about a pen plotter. Though less speedy or precise than a modern printer, watching a pen glide across the page, mimicking human drawing, is mesmerizing. This p…

Over on YouTube [Electronic Wizard] explains how to use the AT24C32 EEPROM for external memory for microcontrollers. He begins by explaining that you don’t want to try modifying your microcon…

[Rex Malik] didn’t need an alarm clock. That’s because he had one of two “home computer terminals” next to his bed and, as you can see in the video below, it made quite a ra…

Since e-ink first hit the market a couple decades back, there’s always murmurs of “that’d be great as a second monitor”— but very, very few monitors have ever been mad…

It’s fair to say that the average Hackaday reader enjoys putting together custom electronics. Some of those builds will be spaghetti on a breadboard, but at some point you’ll probably h…

One of the great things about sharing hacks is that sometimes one person’s work inspires someone else to take it even further. A case in point is [Ivor]’s colorimeter hacking (parts two and three),…

Over a year ago, we took a look at importing a .step file of a KiCad PCB into FreeCAD, then placing a sketch and extruding it. It was a small step, but I know it’s enough for most of you all,…

We’ve all done it at some time — made an electrical connection by twisting together the bare ends of some wires. It’s quick, and easy, but because of how little force required to …

Last time, I described how to write a simple Android app and get it talking to your code on Linux. So, of course, we need an example. Since I’ve been on something of a macropad kick lately, I…

Business cards, on the whole, haven’t changed significantly over the past 600-ish years, and arguably are not as important as they used to be, but they are still worth considering as a remind…

Dedicated word processors are not something we see much of anymore. They were in a weird space: computerized, but not really what you could call a computer, even in those days. More like a fancy ty…

Beyond the simple world of basic PLA filaments there is a whole wild world of additives that can change this humble material for better or worse. The most common additives here are primarily to add…
