OpenCV is an open source library of computer vision algorithms, its power and flexibility made many machine vision projects possible. But even with code highly optimized for maximum performance, we always wish for more. Which is why our ears perk up whenever we hear about a hardware accelerated vision module, …read more
Just like everything else in 2020, the four-day, multi-stage festival of music and art known as Bonnaroo has been cancelled. This would have been [Guy Dupont]’s fifth year making the journey to Tennessee with his friend. Since they couldn’t go, [Guy] decided to build an interactive Bonnaroo mix tape into …read more
We feature a lot of clocks here at Hackaday, but it’s not often that one comes along and makes us stop in our tracks and reconsider the fundamental question: just what is a clock? [Charlyn] has managed it though, with her Nova Light clock, which doesn’t so much measure the …read more
Over the years there have been a variety of methods for a computer to commit its thoughts to paper. Be it a daisy wheel, a dot matrix, a laser, or an inkjet, we’ve all cursed at a recalcitrant printer. There’s another type of printer that maybe we don’t think of …read more
It’s one of the idyls of our age, to imagine oneself lounging in a hot tub watching a golden sunset, glass of wine in hand and the love of your life at your side. Along the way though it’s one that’s become diverted from the original, instead of a Scandinavian …read more
It’s always good to see old hardware saved from the junk pile, especially when the end result is as impressive as this analog gauge weather display put together by [Build Comics]. It ended up being a truly multidisciplinary project, combing not only restoration work and modern microcontroller trickery, but a …read more
Every time we publish a Linux hack that uses a shell script, someone will chime in about how awful it is to program shell scripts. While we like the ubiquity and efficiency, we can’t disagree that the shell is a bit of a hack itself. [Axel Lijencrantz] wants to change …read more
William English, one of the creators of the mouse back in the 60s, passed away last week. And that got me thinking of how amazing it would have been to be in the place that was inventing what would become modern computing interfaces. What a special time! Of course, they …read more

There was a magic moment for a few years around the end of the 1980s, when home computers were better than professional ones. That’s a mighty grand pronouncement, but it refers to the crop of 16-bit home computers that genuinely were far better than nearly all PCs at the time …read more
While these days we’re blessed with the magic of always-on internet connections and cloud services, back in the day software was delivered on physical media. Some of the most reviled media were data tapes, much maligned for their glacial loading times. However, the tangibility did give them some charm, and …read more
Software defined radio or SDR has changed the radio landscape forever. But to use one you need to buy some kind of hardware right? Maybe not. As [Tech Minds] shows in a recent video there are plenty of SDRs publically available on the Internet. We know that isn’t news, but …read more
No matter how much geek cred your old vintage keyboard pulls, it’s not worth suffering through wrist pain or any other discomfort while using it. Especially now, when there are so many points of entry into the rabbit hole world of DIY mechanical keebs.
