How to update the firmware on Raspberry Pi
Essentially, firmware is a form of low-level software that instructs hardware on how to operate and interact with other devices and components. For instance, firmware tells a computer to turn on when you press the power button, and it also tells a Raspberry Pi how to read micro-SD cards and USB drives.
Depending on what you do with your Raspberry Pi, you might never need to update its firmware. Aside from the occasional bug fix, you only have to update your Raspberry if you upgrade a project with new processors, memory chips, or printed circuit boards. You probably won’t need a firmware update if you only use the Raspberry Pi to power a mini RC rover, but if you feel like adding a bit more processing power to a device running Windows 11, you’d better install new firmware.
So, this may mostly not really be required, but it is handy to know if you plan to re-purpose your Pi with newer hardware.

DIY #DOLY
DIY Doly is an #open #robot #project based on #RaspberryPI CM4.
DOLY vs DIY DOLY
*The difference between DIY Doly and the official Doly robot.
While they share the same body shape and electronics, there are some key differences in terms of features and capabilities.
The official Doly robot comes with many advanced features on the software side, such as Edge AI, Block-based programming, self-charging, speech recognition and many more. These features make it a powerful and versatile robot that can be customized to suit a variety of applications and use cases.
On the other hand, the DIY Doly project is designed to be a template for creating a customized robot. While it shares the same body and similar electronics as the official Doly robot, it does not come with pre-loaded software. This means that you will need to program the robot yourself, using whatever software or programming language you prefer.
It's worth noting that DIY Doly is an open-source project, which means that anyone can contribute to the development of the project and create their own customized version of the robot.
Luckily, both DIY Doly and the official Doly robot share the Raspberry Pi CM4. This makes it easy to find resources for programming and customization, as there are many existing tutorials and projects available online.
So, if you're looking for a fully-featured robot with advanced capabilities, the official Doly robot may be the better choice for you. However, if you're looking more customizable and DIY-friendly robot platform, the DIY Doly project is a great option.
This YouTuber shows off running Steam games on a Raspberry Pi 5
As you might expect, you’re not going to be getting Baldur’s Gate 3 running on max settings on a Raspberry Pi 5. However, the actual results were still pretty impressive. Simple 2D games like Brotato ran fine, and older 3D games like the original Portal were very playable. Strangely enough, Terraria gave the Pi 5 a hard time, despite not being a graphically intense game.
Yes, it’s not a gaming computer by any means, but it is pretty good bang for the buck, and also pretty versatile.

The Velo AI smart bike light.
"In moving from radar to a camera-based solution, the aim was to create a device that could tell the cyclist 'a lot more about what's going on in the world and do a lot of things that the radar can't do'. The device would need to help cyclists by providing situational awareness and alerts about nearby vehicles. This includes the ability to distinguish, using computer vision algorithms, between different vehicle types, as well as to estimate their relative speed and to identify and predict driver behaviour."
"Raspberry Pi Compute Module 4 is in effect the brain of the Copilot, aided by a custom Hailo AI co-processor to run the neural networks required for the device's computer vision. A fixed-lens Arducam camera is used to record video footage."
"The Copilot is supplied with a mount to fix it to a bike's seat post or saddle rail, with the camera facing rearward. The AI analyses the live video footage and, depending on the type of driver behaviour detected, custom alerts may be triggered -- audible for the cyclist, and flashing LED light patterns to alert the driver behind."
The article doesn't mention it, but "velo" means bike in French.
