There’s been a lot of buzz about Meshtastic lately, and with good reason. The low-power LoRa-based network has a ton of interesting use cases, and as with any mesh network, the more nodes there are, the better it works for everyone. That’s why we’re excited by this super-affordable Meshtastic kit that lets you get a […]
Lucid dreaming is the state of becoming aware one is dreaming while still being within the dream. To what end? That awareness may allow one to influence the dream itself, and the possibilities of that are obvious and compelling enough that plenty of clever and curious people have formed some sort of interest in this […]
What’s that smell? If you can’t tell, maybe a new laser system from CU Bolder and NIST can help. The device is simple and sensitive enough to detect gasses at concentrations down to parts per trillion. The laser at the system’s heart is a frequency comb laser, originally made for optical atomic clocks. The laser […]
There was a time when the line between typewriters and word processing software was a bit fuzzy. [Poking Technology] found a Xerox 6040 which can’t decide what it is. It looks like a typewriter but has a monitor and a floppy drive, along with some extra buttons. You can watch him tear it down in […]
Just about any 3D printer can be satisfying to watch as it works, but delta-style printers are especially hypnotic. There’s just something about the way that three linear motions add up to all kinds of complex shapes; it’s mesmerizing. Deltas aren’t without their problems, though, which led [Bruno Schwander] to undertake a trio of interesting […]
Inspired by the N64: Recompiled project, XenonRecomp does something similar, except for the PowerPC-equipped Microsoft Xbox 360 game console. Based around the triple-core IBM CPU codenamed ‘Xenon‘, the Xbox 360 was released in 2005 and generally quite successful over its lifespan despite its Red Ring of Death issues. Although the current Xbox Series X supports […]
In our wider community we are all familiar with the idea of open source software. Many of us run it as our everyday tools, a lot of us release our work under an open source licence, and we have a pretty good idea of the merits of one such document over another. A piece of […]
This week, Elliot Williams and Tom Nardi start off the episode by announcing Arduino co-founder David Cuartielles will be taking the stage as the keynote speaker at Hackaday Europe. In his talk, we’ll hear about a vision of the future where consumer electronics can be tossed in the garden and turned into compost instead of […]
As part of the payloads on the Firefly Blue Ghost Mission 1 (BGM1) that recently touched down on the Moon, the Lunar GNNS Receiver Experiment (LuGRE) has become the first practical demonstration of acquiring and tracking Earth orbital GNSS satellites. LuGRE consists of a weak-signal GNSS receiver, a high-gain L-band patch antenna the requisite amplification […]
The fine researchers at Google have released the juicy details on EntrySign, the AMD Zen microcode issue we first covered about a month ago. And to give away the punchline: cryptography is hard. It’s hard in lots of ways, but the AMD problem here is all about keeping track of the guarantees provided by cryptographic […]
