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 […]
Turn the clock back six decades or so and imagine you’re in the nascent computer business. You know your product has immense value, but only to a limited customer base with the means to afford such devices and the ability to understand them and put them to use. You know that the market will eventually […]
It should come as no surprise that we here at Hackaday are big boosters of autonomous systems like self-driving vehicles. That’s not to say we’re without a healthy degree of skepticism, and indeed, the whole point of the “Automate the Freight” series is that economic forces will create powerful incentives for companies to build out […]
When the internal rechargeable battery in his wireless mouse died, [cmot17] decided it was the perfect excuse for making a couple of modifications. The Logitech MX Master isn’t exactly a budget mouse to begin with, but that doesn’t mean there’s no room for improvement. With the addition of a larger battery and USB-C charging port, […]
The vintage Macintosh all-in-one computers were a design icon, as well as being highly useful machines in the 80s and 90s. In the decades since, they’ve been used for everything from web servers to aquariums, but that’s not all. [Arcade Jason] decided to grab an old Macintosh Plus and turn it into a vector display. […]
