In a recent episode of Tom's Hardware: The Pi Cast, Raspberry Pi CEO Eben Upton revealed that 10 million RP2040 chips have been made since 2021 and that there could be more Raspberry Pi stores opening in the future.
=> ↺ Mice explore virtual worlds with a Raspberry Pi-powered VR headset
A Raspberry Pi 4 runs the Godot video game engine inside the headset, and the mice view the output through a dual-SPI display. Researchers created virtual scenes in Godot to test the ability of mice in various scenarios, such as avoiding VR cliffs and reacting to looming objects of various sizes coming towards them at different speeds.

LILYGO recently launched a tiny ESP32-S3 device equipped with a Walkie-Talkie module and other peripherals such as an OLED display, a speaker and a mic and a 18650 battery holder. The company also featured an ESP32 device with a touch-screen LCD display equipped with a stylus pen.
=> ↺ Arduino Library Brings Rtl_433 To The ESP32
If you have an RTL-SDR compatible radio there’s an excellent chance you’ve heard of the rtl_433 project, which lets you receive and decode signals from an ever-expanding list of supported devices in the ISM radio bands. It’s an incredibly useful piece of software, but the fact that it requires an external software defined radio and a full-fledged computer to run dictated the sort of projects it could realistically be used for.
Everyone is talking about Matter, Bluetooth, Zigbee, and Zwave, but before these complex communication technologies, we had one simple, robust one that our sensors and devices used to leverage: 433MHz. It may be too simplistic to talk about 433 MHz as a technology as there are different and various usages of this frequency. You can find it being used in numerous devices around your home, from your outdoor temperature sensors, and security sensors to the tire pressure sensors in your car.
