If you want to get around Monaco, a map — digital or otherwise — is probably the best way to navigate. But if you just want to appreciate the city’s form in a more artistic way, you might enjoy [Terence Grover’s] latest project—a backlit topographic map of the unique principality. The touch mode allows one to draw patterns across the map. The project started with a QGIS mesh of Monaco, with the data fed through the Open-Meteo elevation API, which takes into account building heights. This was used as the basis for the heights of 179 pieces of 20 mm x 20 mm acrylic. These were assembled into a laser cut steel base, and were sanded on all sides but the base in order to allow them to diffuse light more effectively. Strips of CS8812 LEDs are used to light the plastic towers, driven by a pair of Adafruit Feather RP2040 Scorpio boards. They’re fed pixel data from a Raspberry Pi 5, which runs a Flask panel accessed over an iPad. This allows control over the LED map display, showing things like civic data, highlighted events, and weather. There’s even a touch-sensitive mode that lets one paint fun patterns across the representation of the city. We love a good artistic map, particularly when they’re full of LEDs and represent useful information.

Picture a payphone. Not a sleek, reimagined version, just an actual, beat-up Telefónica booth, the kind you might walk past on a Barcelona street without a second glance. Except this one is overtaken by moss. And if you pick up the handset, the Earth answers. That’s the premise of 2147: A Voice from the Future, an interactive installation by Cris Olmedo of Divina Machina, the digital art branch of creative innovation studio QS Ventures. The piece was presented at Sónar+D, set against the medieval backdrop of the Llotja de Mar in Barcelona. That pairing alone says something: one of the oldest commercial buildings in the city, hosting an open-ended conversation with an AI that speaks on behalf of a future planet. Designer: Cris Olmedo (Divina Machina) The concept is disarmingly simple. You pick up the handset. The AI, voiced through an ElevenLabs system and powered by a Raspberry Pi 5 tucked inside the original booth, responds in real time as a fictional representation of the Earth. No scripts, no predefined dialogue paths, no multiple-choice menus. You take the conversation wherever you want, whether that’s climate, survival, memory, or grief. The Earth, imagined 121 years from now, has things to say. Whether you do is another matter. What makes this work is the object itself. Olmedo didn’t design something new and purposefully futuristic. The booth kept its original Telefónica structure, its original signage, its unmistakably analog bones. Only what’s hidden inside changed. The moss slowly consuming the exterior reads like nature quietly reclaiming something that people gave up on. That tension between the obsolete and the alive does a lot of the emotional heavy lifting here, and it’s a smarter choice than any glowing interface could have been. We tend to think of design as a forward-moving discipline, always chasing newer, faster, more capable. But 2147 asks a different question: what happens when you take something we’ve already discarded and give it a new reason to exist? The payphone is a perfect vessel for that question, precisely because it was once the most public, most democratic form of long-distance communication we had. You didn’t need an account, a plan, or a device you owned outright. Just a coin and a number to dial. Now that infrastructure is largely gone. Olmedo took what’s left of it and filled it with something else entirely. That’s not just clever art direction. It’s a genuinely pointed observation about how we build things, discard them, and eventually recognize that the shell still has something to offer. The fact that this installation lives inside an actual retired Telefónica booth, rather than a replica, matters more than it might seem. The year 2147 gives me pause, in the best way. It’s far enough to feel like science fiction, but close enough to feel like a countdown. It’s the kind of temporal framing that shakes you out of the comfortable haze of “we’ll deal with it later.” The Earth speaking through this installation isn’t a distant abstraction. It’s speaking through a receiver you’ve held before, in a language you already understand, about problems you’ve already heard about. The moss is the detail I can’t stop thinking about. It reads as both beautiful and quietly alarming, the natural world slowly spreading over a structure that once represented human connection. As if the planet didn’t wait for us to sort things out. It also turns a mundane artifact into something you actually want to stop and stare at, which is half the job of any good installation. It communicates instantly and without explanation, which is exactly what good design is supposed to do. 2147: A Voice from the Future earns its concept. It’s not a payphone with AI bolted on. It’s a meditation on time, obsolescence, and the conversations we keep putting off. And the most compelling thing about it is that it asks you to start one, right now, handset in hand, with a planet that’s been waiting for you to pick up.

In this paper, we present an experimental evaluation study of the Alternating Direction Method of Multipliers (ADMM), which is a widely used technique in the distributed optimization of power distribution networks. The focus of this study is on how real 5G communication performance affects ADMM in a fully experimental platform that features commercial 5G connectivity and real-time control. The ADMM-based Distributed Optimal Power Flow (DOPF) problem is solved using the IEEE 123-bus unbalanced distribution feeder subdivided into five areas, each managed by a local controller implemented on a Raspberry Pi. To mitigate the impact of the communication network variability, we propose a delay threshold-based mechanism that yields a 7.75% reduction in convergence time compared to a no-threshold baseline. We also devised a policy to dynamically update the threshold value based on communication and computation conditions, achieving a 26.42% reduction in the convergence time compared with the static optimal threshold. These results demonstrate the potential of adaptive, communication-aware control strategies for real-world Smart Grid (SG) deployments.

Last week marked the release of an updated Raspberry Pi OS that moved to Linux 6.18 LTS from its former Linux 6.12 kernel base along with making a number of other package updates. Given the jump to the newer Long Term Support kernel and other improvements, I ran some fresh benchmarks on the Raspberry Pi 5 (Raspberry Pi 500+) to see the performance difference out of the updated operating system.

Cytron is currently selling a Raspberry Pi 4 Model B “Special Value Board” with 4GB or 8GB of RAM, whose unique feature is to be clocked at 1.25 GHz instead of 1.8 GHz. The Raspberry Pi 4 initially launched with a 1.5 GHz BCM2711 SoC in 2019, but all recent boards are upgraded to the BCM2711C0 clocked at 1.8 GHz, first found in the Raspberry Pi 400 keyboard PC. So that 1.25 GHz version is odd, let’s check it out. Raspberry Pi 4 “Special Value Board” specifications: SoC – Broadcom BCM2711C0 quad-core Cortex-A72 (ARMv8) @ 1.25 GHz max with VideoCore VI GPU supporting OpenGL ES 3.0 graphics System Memory – 4GB or 8GB LPDDR4-3200 Storage – microSD card slot Video Output & Display I/F 2x micro HDMI ports up to 4Kp60 (Currently 1080p60 max. in dual-display configuration, although 2x 4Kp30 is being worked on) 3.5mm AV port with composite video [...] The post Discounted 1.25 GHz Raspberry Pi 4 Model B shows up online appeared first on CNX Software - Embedded Systems News.
