When I got the call asking if I’d be willing to fly down to Kennedy Space Center and cover an event, I agreed immediately. Then about a week later, I remembered to call back and ask what I was supposed to be doing. Not that it mattered, I’d gladly write a few thousand words about […]
The origin story of software takes us back past punch card computers and Babbage’s Difference Engine to a French weaver called Joseph Marie Jacquard. Jacquard created a way to automate mechanical looms, giving weavers the ability to change a loom’s pattern by simply switching punch cards. This invention not only made it possible to produce […]
In any mechanical field of work, accurate measurement is key to success. [Patrick Panikulam] knows this well, and decided to build a device that would be useful for some of the more tricky measurement tasks he was encountering. [Patrick]’s digital multi-functional measurement tool packs a bunch of useful hardware into a pocket-sized form factor. There’s […]
In an era where everything seems to be getting “smarter” every year, it will probably come as no surprise to find that even relatively middling networking hardware is now packing advanced features and considerable computational power. A case in point is the Dell N1108T-ON Ethernet switch. Despite only costing around $100 USD on the second […]
One rite of passage back in the good old days of owning a TRS-80, Commodore 64, or similar vintage computer was writing your own game. It probably wouldn’t be very good, but it wouldn’t be much worse than most of the stuff that was out there, either. Today, trying to get a kid interested in […]
Digital watches are a pretty neat idea, and are a great way to experiment with designing and building low-power circuits. That’s what [Eric Min] did with this neat smart watch build. It’s based around an nRF52832 SoC that does all of the heavy lifting, including connecting to a smartphone to get the time when the […]
Over the years, readers have often commented that microcontrollers (or more specifically, the Arduino) are overkill for many of the projects they get used in. The admonition that the creator “Should have used a 555” has become something of a rallying cry for those who think modern electronic hobbyists are taking the easy way out. […]
From building your own analog effects pedal to processing audio through micro controllers, a lot of musicians love building their own boxes of sound modification. In his entry for the 2019 Hackaday Prize, [Craig Hissett] has a project to build an all-in-one multi-effects stomp box. At the center of the box is a Raspberry Pi […]
By pretty much any metric you care to use, the last couple of decades has been very good for the open source movement. There was plenty of pushback in the early days, back when the only people passionate about the idea were the Graybeards in the IT department. But as time went on, more and […]
Join us Wednesday at 5:00 PM Pacific time for the Easy EDA Hack Chat with Dillon He! Note the different time than our usual Hack Chat slot! Dillon will be joining us from China. Since the birth of electronic design automation in the 1980s, the universe of products to choose from has grown tremendously. Features […]
