🔭 Laser Projected Asteroids on the ESP32
The article (with video) describes the process of recreating of classic old game for laser projection using esp32 controller. The project includes both schematics and explained software part with detailed explanations. The game is implemented using the Esspressif IDF using PlatformIO to build and deploy.
"All in all, it's a pretty successful project. Even with my very low power 5mw laser, I can get around 2m x 2m projection at a good brightness in a dark room."

📹 Build a Face Recognition System for $60 with the New Nvidia Jetson Nano 2GB and Python
The Nvidia Jetson Nano 2GB dev board is a single-board computer that goes for $59 and runs AI software with GPU-acceleration.
The kind performance you can get out of a $59 single-board computer is kind of amazing. Let’s use it to create a simple version of a doorbell camera that tracks everyone that walks up to the front door of your house. With face recognition, it will instantly know whether the person at your door has ever visited you before — even if they were dressed differently.

📰 NASA Mars Perseverance Rover Uses Same PowerPC Chipset Found in 1998 G3 iMac
NASA's Perseverance rover, which recently made history landing on the surface of Mars, is powered by the same processor used in an iMac more than 23 years old.
As reported by NewScientist, the rover includes the PowerPC 750 processor, the same chip used in the G3 iMac in 1998.
The main chipset is the same; however, there are differences between the version of the processor shipped in a consumer computer and the one exploring space. The processor in the rover is built to withstand temperatures between -67 and 257 degrees Fahrenheit (−55 and 125 degrees Celsius) and comes with an added $200,000 price tag.
The PowerPC 750 processor was ahead of the game for its time, featuring a single-core, 233MHz processor, 6 million transistors (compared to today's 16 billion in a single chip), and based on 32-bit architecture.
