You can use a microcontroller to build a clock. After all, a clock is just something that counts the passage of time. The only problem is that microcontrollers can’t track time very accurately. They need some kind of external timing source that doesn’t drift as much as the microcontroller’s primary clock oscillator. To that end, [Josh] […]
The Etch-A-Sketch has been a popular toy for decades. It can be fun to draw on, but you have to get things right the first time, because there’s no undo button. [Tekavou] decided to recreate this popular toy in digital form instead to give it more capabilities. The build relies on an Inkplate e-paper screen […]
The 2025 One Hertz Challenge asks you to build a project that does something once every second. While that has inspired a lot of clock and timekeeping builds, we’re also seeing some that do entirely different things on a 1 Hz period. [junkdust] has entered the contest with a project that does something rather mathematical […]
We’re back! This week Jonathan chats with Mattias Wadman and Michael Farber about JQ! It’s more than just a JSON parser, JQ is a whole scripting language! Tune in to find out more about it. https://jqlang.github.io/jq/manual/ https://play.jqlang.org/ https://github.com/wader/jqjq https://github.com/wader/fq https://github.com/01mf02/jaq https://github.com/01mf02/jq-lang-spec/ Did you know you can watch the live recording of the show right on […]
When do you think the first podcast occurred? Did you guess in the 1890s? That’s not a typo. Telefonhírmondó was possibly the world’s first true “telephone newspaper.” People in Budapest could dial a phone number and listen to what we would think of now as radio content. Surprisingly, the service lasted until 1944, although after […]
Facing the horrifying realization that he’s going to graduate soon, EE student [Colin Jackson] AKA [Electronics Guy] needed a business card. Not just any business card: a PCB business card. Not just any PCB business card: a PCB business card that can play pong. [Colin] was heavily inspired by the card [Ben Eater] was handing […]
Hackaday has a long-running series on Mining and Refining, that tracks elements of interest on the human-made road from rocks to riches. What author Dan Maloney doesn’t address in that series is the natural history that comes before the mine. You can’t just plunk down a copper mine or start squeezing oil from any old […]
It’s hard to overstate the impact desktop 3D printing has had on the making and hacking scene. It drastically lowered the barrier for many to create their own projects, and much of the prototyping and distribution of parts and tools that we see today simply wouldn’t be possible via traditional means. What might not be […]
If your guitar needs more distortion, lower audio fidelity, or another musical effect, you can always shell out some money to get a dedicated piece of hardware. For a less conventional route, though, you could follow [Brek Martin]’s example and reprogram a handheld game console as a digital effects processor. [Brek] started with a Sony […]
If you learned to type anytime in the mid-part of the 20th century, you probably either had or wanted an IBM Selectric. These were workhorses and changed typing by moving from typebars to a replaceable wheel. They were expensive, though worth it since many of them still work (including mine). But few of us could […]
