Waveshare UGV Rover – A 6-wheel AI robot built around Raspberry Pi 4/5 and ESP32
https://www.cnx-software.com/2024/05/02/waveshare-ugv-rover-6-wheel-ai-robot-raspberry-pi-4-5-esp32/
The Waveshare UGV Rover is a 6-wheel robot platform based on Raspberry Pi 4 or 5 as well as an ESP32 module and built for remote exploration, object recognition, and autonomous navigation. Since the source code for the platform will be open-sourced it can also be used for educational purposes, programming, robotics, AI experimentation, and many other applications.
This Unmanned Ground Vehicle (UGV) rover features a 2mm thick aluminum body, six 80mm shock-absorbing tires, and a four-wheel drive system controlled by an ESP32 sub-controller. The sub-controller also handles sensors, LiDAR, cameras, and more. The brain or the main controller of the rover is a Raspberry Pi SBC – either a Pi 4B or Pi 5 – which notably handles computer vision and machine learning operations.

How to monitor your home network traffic with a Raspberry Pi
https://www.xda-developers.com/how-to-monitor-your-home-network-traffic-with-a-raspberry-pi/
One of the best ways to ensure the resilience of your home network is to set up a service to monitor its traffic. After all, you can’t fix what you don’t know is an issue, and gathering data will show you what needs to be fixed. Monitoring is also important for network security, as better monitoring systems can detect intrusions, DDoS attacks, or other potential issues as they occur.

CanSat: A tiny, can-sized, Raspberry Pi-powered satellite
https://www.raspberrypi.com/news/cansat-a-tiny-can-sized-raspberry-pi-powered-satellite/
A competition for space-bound students resulted in a tiny, can-sized, Raspberry Pi-powered satellite. Rob Zwetsloot boldly takes a look at it.
What would you do if you had to create a satellite the size of a drinks can? The yearly CanSat competition for students in their teens asks this question, and many teams have answered — including LittleBlueDot.

People are squashing DeepSeek onto their Raspberry Pi mere days after it hit the public eye
https://www.xda-developers.com/deepseek-raspberry-pi-mere-days/
Summary
DeepSeek is an LLM from China that’s causing turbulence in the tech market.
An older version of DeepSeek can run on Raspberry Pi 5 but with slow performance.
The Raspberry Pi community may find a way to enhance DeepSeek’s performance.

USB Stick Hides Large Language Model
https://hackaday.com/2025/02/17/usb-stick-hides-large-language-model/
Large language models (LLMs) are all the rage in the generative AI world these days, with the truly large ones like GPT, LLaMA, and others using tens or even hundreds of billions of parameters to churn out their text-based responses. These typically require glacier-melting amounts of computing hardware, but the “large” in “large language models” doesn’t really need to be that big for there to be a functional, useful model. LLMs designed for limited hardware or consumer-grade PCs are available now as well, but [Binh] wanted something even smaller and more portable, so he put an LLM on a USB stick.
This USB stick isn’t just a jump drive with a bit of memory on it, though. Inside the custom 3D printed case is a Raspberry Pi Zero W running llama.cpp, a lightweight, high-performance version of LLaMA. Getting it on this Pi wasn’t straightforward at all, though, as the latest version of llama.cpp is meant for ARMv8 and this particular Pi was running the ARMv6 instruction set. That meant that [Binh] needed to change the source code to remove the optimizations for the more modern ARM machines, but with a week’s worth of effort spent on it he finally got the model on the older Raspberry Pi.
World’s First USB Stick with Local LLM – AI in Your Pocket!
https://www.youtube.com/watch?v=SM-fFsE9EDU
Cherry on top of the cake, it requires no dependency, you can connect it to any computer, create a new file and the content will be automatically generated from the USB side. Essentially the first ever native LLM USB.
This was done on an 8-year-old pi zero, which has 512MB of Ram and an arm1176jzf-s CPU.
To be able to run LLM, let alone with llama.cpp on this was quite something. Arm1176jzf-s was first released in 2002, it implements armv6l isa. It took 12 hours just to compile the whole source of llamacpp and more than a week for me to make it run on an unsupported isa.
The performance is quite terrible and offer no practical use, but it is a fun look into the future, where LLM can run potentially anywhere.

“Glasses” That Transcribe Text To Audio
https://hackaday.com/2025/03/19/glasses-that-transcribe-text-to-audio/
It’s funny to think about how advanced this project really is. Jump back to the dawn of the microcomputer era, and such a device would have been a total flight of fancy—something a researcher might make a PhD and career out of. Indeed, OCR and speech synthesis alone were challenge enough. Today, you can stand on the shoulders of giants and include such mighty capability in a homebrewed device that cost less than $50 to assemble. It’s a neat project, too, and one that we’re sure taught [Akhil] many valuable skills along the way.
Vision Glasses V2 for the Blind to Transcribe Text to Audio
https://www.instructables.com/Vision-Glasses-V2-for-the-Blind-to-Transcribe-Text/
This project is the second, more advanced version of my Smart AI Glasses for the Blind to Transcribe Text to Audio in real time using Raspberry Pi Zero. These glasses scan text and broadcast the text aloud. Allowing visually impaired individuals to have access to more written text that isn’t translated in a form understandable to them (braille, audio, etc.).

The success and popularity of Raspberry Pi boards is certainly well-deserved; but over time, many users have noticed and complained about the lack of a power button. Finally, the desired button has been added to the new Raspberry Pi 5 model, but owners of earlier models may find this project useful. Let’s build a Raspberry Pi Smart Power Button.
