Run Xbox 360 Games On Your PC With XenonRecomp

March 7, 2025 by 8 Comments

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 running a number of Xbox 360 games, this is done via emulation and only 632 games out of 2,155 are supported.

This is where XenonRecomp not only promises turning the games into native (x86) software, but also allowing for a range of graphical improvements. Best of all, it allows for Xbox 360 games to be preserved instead of linked to an obsolete console. That said, much like with N64Recomp, it’s not a simple matter of running a tool over the PPC binary. You’re expected to have in-depth systems knowledge, with the tools in XenonRecomp assisting with the decompilation (into C++) and the recompilation into x86 binaries, but support for PPC instructions, VMX (vector instructions) and aspects like jump table conversion and (currently missing) MMIO support are likely to present an enterprising developer with hours of fun to implement and debug when issues arise.

Open Source Hardware, How Open Do You Want It To Be?

March 7, 2025 by 43 Comments

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 open source software has all of its code released under a permissive licence that explicitly allows it to be freely reproduced and modified, and though some people with longer beards take it a little too seriously at times and different flavours of open source work under slightly different rules, by and large we’re all happy with that.

When it comes to open hardware though, is it so clear cut?  I’ve had more than one rant from my friends over the years about pieces of hardware which claim to be open-source but aren’t really, that I think this bears some discussion.

Open Source Hardware As It Should Be Done

To explore this, we’ll need to consider a couple of open source hardware projects, and I’ll start close to home with one of my own. My Single 8 home movie cartridge is a 3D printable film cartridge for a defunct format, and I’ve put everything necessary to create one yourself in a GitHub repository under the CERN OHL. If you download the file and load it into OpenSCAD you can quickly create an STL file for your slicer, or fiddle with the code and make an entirely new object. Open source at its most efficient, and everyone’s happy. I’ve even generated STLs ready to go for each of the supported ISO values.

Hackaday Podcast Episode 311: AirTag Hack, GPS Rollover, And A Flat-Pack Toaster

March 7, 2025 by 5 Comments

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 sitting in a landfill for the next 1,000 years or so.

You’ll also hear about a particularly clever manipulation of Apple’s AirTag infrastructure, how a classic kid’s toy was turned into a unique display with the help of computer vision, and the workarounds required to keep older Global Positioning System (GPS) hardware up and running. They’ll also cover DIY toasters, extracting your data from a smart ring before the manufacturer can sell it, a LEGO interferometer, and a new feature added to the Bus Pirate 5’s already impressive list of capabilities.

Capping off the episode there’s a discussion about the surprising (or depending on how you think about it, unsurprising) amount of hardware that was on display at FOSDEM this year, and the history of one of man’s most infernal creations, the shopping cart wheel lock.

Check out the links below if you want to follow along, and as always, tell us what you think about this episode in the comments!

GNSS Signals Tracked On The Moon By LuGRE

March 7, 2025 by 15 Comments

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 and filter circuits, designed to track a number of GPS and Galileo signals.

Designed by NASA and the Italian Space Agency (ISA), the LuGRE payload’s goal was to demonstrate GNSS-based positioning, navigation and timing at the Moon. This successful demonstration makes it plausible that future lunar missions, whether in orbit or on the surface, could use Earth’s GNSS satellites to navigate and position themselves with. On the way to the lunar surface, LuGRE confirmed being able to track GNSS at various distances from the Earth.

Both LuGRE and BGM1 are part of NASA’s Commercial Lunar Payload Services (CLPS) program, with BGM1 delivering a total of ten payloads to the Moon, each designed to study a different aspect of the lunar environment, as well as hardware and technologies relevant to future missions.

This Week In Security: Zen Jailbreak, Telegram Exploit, And VMware Hyperjack

March 7, 2025 by 7 Comments

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 primitives.

The Long Goodbye: More Instruments Shut Down On The Voyagers As End Nears

March 7, 2025 by 50 Comments

Saying farewell is hard, and in the case of the Voyager 1 & 2 spacecraft doubly so, seeing as how they have been with us for more than 47 years. From the highs of the 1970s and 1980s during their primary mission in our Solar System, to their journey into the unknown of Deep Space, every bit of information which their instruments record and send back is something unique that we could not obtain any other way. Yet with the shutting down of two more instruments, both spacecraft are now getting awfully close to the end of their extended missions.

Last February 25 the cosmic ray system (CRS) on Voyager 1 was disabled, with the Low Energy Charged Particle Instrument (LECP) on Voyager 2 to follow on March 24. With each spacecraft losing about 4 watts of available power per year from their RTGs, the next few instruments to be turned off are already known. Voyager 1’s LECP will be turned off next year, with that same year Voyager 2’s CRS also getting disabled.

This would leave both spacecraft with only their magnetometer (MAG) and plasma wave subsystem (PWS). These provide data on the local magnetic field and electron density, respectively, with at least one of these instruments on each spacecraft likely to remain active until the end of this decade, possibly into the next. With some luck both spacecraft will see their 50th birthday before humanity’s only presence in Deep Space falls silent.

Open Safety In The Auto Business: Renault Shares Its Battery Fire Suppression Tech

March 7, 2025 by 31 Comments

As consumers worldwide slowly make the switch from internal combustion vehicles to lower-carbon equivalents, a few concerns have appeared about electric vehicles. Range anxiety is ebbing away as batteries become bigger and chargers become more frequent, but a few well-publicized incidents have raised worries over fire safety.

Lithium-ion batteries can ignite in the wrong circumstances, and when they do so they are extremely difficult to extinguish. Renault has a solution, and in a rare moment for the car industry, they are sharing it freely for all manufacturers to use.

The innovation in question is their Fireman Access Port, a standardized means for a fire crew to connect up their hoses directly to the battery pack and attack the fire at its source. An opening is covered by an adhesive disk designed to protect the cells, but breaks under a jet of high-pressure water. Thermal runaway can then be halted much more easily.

The licensing terms not only allow use of the access port itself, but also require any enhancements be shared with the rest of the community of automakers using the system. This was the part which caught our interest, because even if it doesn’t come from the same place as the licences we’re used to, it sounds a lot like open source to us.

Oddly, this is not the first time Renault have open-sourced their technology, in the past they’ve shared an entire car.
