Dot matrix printers are the dinosaurs that won’t go extinct. They are not unlike a typewriter with the type bars behind the ink ribbon replaced by a row of metal pins controlled by solenoids,…

Unlike DOS, early versions of Windows, and most *nixes, the classic Mac operating system is weird. Contained in the ROM are subroutines to draw windows, pop up dialog boxes, and other various tasks…

[Peter Lehnér] has designed a brilliant 7-segment flip-segment display that doesn’t really flip. In fact, it doesn’t use electromagnets at all. This one is 3D printed and hand cranked. …

3D printing isn’t something you would usually associate with a high precision device, but this one shows that it can be used to create rather intricate things when needed. The Openflexure is …

If you collect trading cards of any kind, you know that storage quickly becomes an issue. Just ask [theguymasamato]. He used to be really into trading cards, and got back into it when his kids caug…

Dave Jones is something of a celebrity in the hacker and maker communities, bringing his considerable knowledge and experience to bear on a wide variety of electronic and engineering topics. His un…

Back in the early days of radio, it was quickly apparent that the technology would revolutionize warfare, but only if some way could be found to prevent enemies from hearing what was said. During W…

[Thomas Sanladerer] wanted to create some molds using 3D printing for concrete and plaster. He used a delta printer with flexible filament and documented his process in the video below. If you&#821…

Here at Hackaday, we love knobs and buttons. So what could be better than one button? How about 16! No deep philosophy about the true nature of Making here; [infovore], [tehn], and [shellfritsch] p…

Here’s a neat trick for your next 3D-printer build or retrofit: a Z-axis sensor using a DIY strain gauge made from SMD resistors. We’re betting it could have plenty of other application…

Before the GoPro, shooting video of messy, fast-paced, or dangerous things was very different. There were commercial sports camera rigs and various industrial solutions, but the GoPro, with its wat…

Once again, Uber found a company to build their ‘air taxis’. This time it’s Boeing. While there are no details on the Boeing bird, I’m going to propose again that Uber buy t…

For an electronics person, building the mechanics of a robot — especially a robust robot — can be somewhat daunting. [Jithin] started with an off-the-shelf 4 wheel drive chassis to buil…

The MT3608 is a popular boost converter, able to easily step up DC voltages in useful ranges, at an incredibly low cost. Modules can be sourced from eBay for less than $2, built on a PCB, ready to …

We use a lot of voltmeters and we bet you do too. We have some big bench meters and some panel meters and even some tiny pocket-sized meters. But biological researchers at the University of Chicago…

It is an easy trap for us to write only about what we know when covering a topic, thus missing an entire facet of our subject matter. Take retrocomputing for example; we might write about American …

There’s a new soap opera that I can’t stop watching. Actually, I wish I could change the channel but this is unfortunately happening in real life. It’s likely the ups and downs of…
