We see all kinds of projects come across the news desk at Hackaday. Sometimes it’s a bodge, neatly executed, that makes us laugh out loud at its simple ingenuity. Other times, it’s a case of great skill and attention to detail, brought to bear to craft something of great beauty. [Greg Davill]’s LED cube is […]
Like the tastes of the makers that build them, LED cubes come in all shapes and sizes. From the simplest 3x3x3 microcontroller test, to fancier bespoke installations, they’re a great way to learn a bunch of useful embedded techniques and show off at the same time. [kbob] has done exactly that in spades, with a […]
To a speaker of English, a sign asking ‘Was?” may not make much sense. In German, however, the question is a more thought-provoking “What?” That’s exactly the point of this faux-neon sign created by [noniq]. The sign uses silicone-enclosed “neon-like” LED strips to spell out the question for all to see — and ponder. While […]
There’s no doubting the allure of a nicely crafted LED cube; likewise, there’s no doubting that they can be a tremendous pain to build. After all, the amount of work scales as the cube of the number of LEDs you want each side to have, and let’s face it – with LED cubes, the bigger, […]
For the average person, decorating at home is as simple as a few choice picks from the IKEA catalogue. Makers are a different breed, though – preferring something customized and glowing. This LED triangle is a particularly great example of the form, and the latest benchmark for excellence to come out of [scanlime’s] workshop. Hailing […]
You’d think that something made out of glass and epoxy would transmit a decent amount of light. Unfortunately for [Jeremy Ruhland], it turns out that FR4 is not great light pipe material, at least in one dimension. The backstory on this has to do with #badgelife, where it has become popular to reverse mount SMD […]
It’s time once again for another installment in “Milspec Teardown”, where we get to see what Uncle Sam spends all those defense dollars on. Battle hardened pieces of kit are always a fascinating look at what can be accomplished if money is truly no object. When engineers are given a list of requirements and effectively […]
Microcontrollers are a great way to learn about developing for embedded systems. However, once you outgrow their capabilities, FPGAs bring muscle that’s hard for even the fastest-clocked micros to match. If you’re doing anything with high-speed signals, loads of RAM, or something that requires lots of parallel calculation, you can’t go past FPGAs. Dev boards […]
