We might consider PCB panels as simply an intermediate step towards getting your PCBs manufactured on the scale of hundreds. This is due to, typically, an inability to run traces beyond your board – and most p…
It’s fairly insignificant in the scheme of things, and there’s no hardware as yet for us to look at, but there it is. Tucked away in a device tree file, the first mention of a Raspberry Pi 500. We take this to mea…
Ever want a seriously powerful PCB for charging a Li-Ion pack? Whatever you want it for, [Redherring32] has got it — it’s a board bearing the TPS25750D and BQ25713 chips, that lets you push up to 100 W into you…
What is with all the wasted space on keyboards? There’s a whole back side just sitting there doing nothing. But how can you use the back at the same time as the front? All the board sandwiches must be wired t…
Bits of material levitating against gravity, a stream of water deflected by invisible means, sparks of light appearing out of thin air; with observations like those, it’s a wonder that the early experiments into t…
While the death of Apple’s Lightning Connector can’t come soon enough, swapping the ports on their products as “category-defining innovations” seems a bit of a stretch. [Ken Pillonel] has designed a set of streaml…
For many a hacker, stenciling a board for the first time is a game-changing experience – the solder joints you get, sure do give your PCB the aura of a mass-manufactured device. Now, you might not get a perfect p…
It’s pretty easy to take a balloon, fill it up with helium, and send it up in to the upper atmosphere. It’s much harder to keep track of it and recover it when it falls back to Earth. If you’re trying to do that,…
It’s 2024. You’ve probably got one or more pairs of wireless headphones around the house. [Barnso] prefers wired headphones with a long cable, but he also decries the fact that it often gets tangled in his cha…
Those of us old enough to remember BBS servers or even rainbow banners often go down the nostalgia hole about how the internet was better “back in the day” than it is now as a handful of middlemen with a str…
For months before liftoff, the popular press had been hyping up the fact that the Polaris Dawn mission would include the first-ever private spacewalk. Not only would this be the first time anyone who wasn’t a p…
If you’ve ever designed a battery-powered device with a Pi Zero, you have no doubt looked into decreasing its power consumption. Generic advice, like disabling the HDMI interface and the onboard LED, is o…
In an age where our gadgets allow us to explore the cosmos, we stumbled upon sounds from a future past: an article on historical signals from Mars. The piece, written by [Paul Gilster] of Centauri Dreams, cites a…
Modern smartphones try and provide a number of useful features to their users, and yet, they’re not exactly designed with human needs in mind. A store-bought smartphone will force a number of paradigms and f…
Modern gaming laptops are in an uncomfortable spot – often too underpowered for newest titles, but too bulky to be genuinely portable. It doesn’t help they’re not often upgradeable, so you’re stuck with what yo…
The Voyager 2 spacecraft’s energy budget keeps dropping by about 4 Watt/year, as the plutonium in its nuclear power source is steadily dropping as the isotope decays. With 4 Watt of power less to use by its s…
Marble art madness from a marvelous machine Arduino Team — October 3rd, 2024 Marbles are underrated. They’re very round, roll well, tend to be pretty shiny, and come in all sorts of neat colors. That last cha…
As Hackaday writers we don’t always know what our colleagues are working on until publication time, so we all look forward to seeing what other writers come up with. This week it was [Al Williams] with “Things You…
Let’s say you’re going to a music festival. You could just take water, sunscreen, and a hat. Or, you could take a rad glowing witch’s staff to really draw some eyes and have some fun. [MZandtheRaspberryPi] recen…
This week Jonathan Bennett and and Simon Phipps chat with Gary Williams about OggCamp! It’s the Free Software and Free culture unconference happening soon in Manchester! What exactly is an unconference? How long h…
