Raspberry Pi ☛ DIY home automation with Raspberry Pi
Home automation is not only useful but can also be a great deal of fun, particularly when setting up cool automations or connecting different devices together in new ways. It can also help boost the energy efficiency and security of your home; there are a wealth of practical reasons to start experimenting with this technology. Although there are different vendor-specific automation systems out there, we prefer one that doesn’t ‘lock’ you into one provider. One such platform is Home Assistant (home-assistant.io), a free open-source operating system designed with flexibility and independence in mind. Home Assistant is a huge topic, but here we’ll look at the basics of setting up a server to get you started on your automation journey.

Tom's Hardware ☛ This Raspberry Pi portable cyberdeck is straight out of a sci fi movie
The main board powering the Vertical Runner is a Raspberry Pi 4 8GB model. It's connected to a 3.5-inch WaveShare IPS LCD touchscreen which can be used for user input alongside a Bluetooth keyboard. It also has a BrosTrend dual band wi-fi adapter which is exceptionally useful for ethical hacking on the go.

Jeff Geerling ☛ How to build Ollama to run LLMs on RISC-V Linux
RISC-V is the new entrant into the SBC/low-end desktop space, and as I'm in possession of a HiFive Premier P550 motherboard, I am running it through my usual gauntlet of benchmarks—partly to see how fast it is, and partly to gauge how far along RISC-V support is in general across a wide swath of GNU/Linux software.

CNX Software ☛ OpenWISP open-source solution facilitates the management of OpenWrt router fleets
Last month, I wrote about the WL-AC1000 AP controller, a hardware-based solution to monitor fleets of routers, and wondered why the company (Wallys) did not provide a software solution instead. It was pointed out to me that software AP controller solutions for OpenWrt routers do exist, but they looked not mature. After a quick search, I found OpenWISP described as an “open-source solution for efficient IT network deployment, monitoring & management” designed for OpenWrt GNU/Linux routers. OpenWISP allows organizations with several routers to manage them in a centralized location, get alerts when issues occur, upgrade the firmware of multiple routers with a few clicks, create users with permissions to access specific routers, and so on.

Hackaday ☛ Good-Looking HAT Does Retro Displays Right
Mick Jagger famously said that you cain’t always get what you want. But this is Hackaday, and we make what we want or can’t get. Case in point: [Andrew Tudoroi] is drawn to retro LEDs and wanted one of Pimoroni’s micro-LED boards pretty badly, but couldn’t get his hands on one. You know how this ends — with [Andrew] designing his first PCB.

Hackaday ☛ Making Products For Fun And (Probably No) Profit
If you’re like most makers, you have a few product ideas kicking about, but you may not have made it all the way to production of those things. If you’re thinking about making the leap, [Simone Giertz] recently discussed all the perils and pitfalls of the process from idea to reality.

Hackaday ☛ This Thermometer Rules!
A PCB ruler is a common promotional item, or design exercise. Usually they have some sample outlines and holes as an aid to PCB design, but sometimes they also incorporate some circuitry. [Clovis Fritzen] has given us an ingenious example, in the form of a PCB ruler with a built-in thermometer.

CNX Software ☛ YOLO-Jevois leverages YOLO-World to enable open-vocabulary object detection at runtime, no dataset or training needed
YOLO is one of the most popular edge Hey Hi (AI) computer vision models that detects multiple objects and works out of the box for the objects for which it has been trained on. But adding another object would typically involve a lot of work as you’d need to collect a dataset, manually annotate the objects you want to detect, train the network, and then possibly quantize it for edge deployment on an Hey Hi (AI) accelerator.
