📟 How to design a motherboard for your electronics project
After the prototyping phase of any electronics project, I like to make a "Motherboard" PCB. For this phase I will continue to use breakout boards for all of the individual components, but link them together using a PCB.
This allows the PCB design to stay simple and flexible, and makes them easy to hand manufacture them in my workshop. This is a great setup if you want to do a small (10ish) beta run of your project before designing a full product. I have shipped many hardware products using this stage, it's a great way to validate your MVP before putting money into tooling and CM bring up.
This tutorial will walk through the process that I follow to create a motherboard. The intended audience is someone who has already wired up a prototype on a breadboard, and wants to get started bundling them together into a motherboard.

💻 The Lisperati1000 Is a Cyberdeck Terminal Dedicated to Lisp Programming
If you’re new to coding and want something easy to use, Python is great. For performance and capability, it’s hard to beat programming in C. But if you need some complex algorithms — particularly algorithms that do a lot of heavy mathematical lifting — then Lisp is the ideal choice.
Dr. Conrad Barski has a long history of a using Lisp to program enterprise medical software and has even authored books on the language. He wanted a small, portable device for coding Lisp on the go and built the Lisperati1000 cyberdeck terminal for the job.
The Lisperati1000 is a very compact device based on the Raspberry Pi Zero W single-board computer. Its most striking feature is the 8.8” LCD display, which has an ultra-wide aspect ratio with a resolution of 1920x480.

🚀 How SpaceX lands Starship (optimal trajectory)
As part of a personal push to learn more about non-linear control, I have been playing around with a pretty powerful method known as trajectory optimization. Once the base code is set up, it’s fairly easy to go apply to various systems.
While waiting for Starship SN15 to launch (it was in fact scrubbed, sad), I decided to pull together an estimate for some of it’s dynamics and see if I could get my toy 2D simulation to perform that epic flip and land itself.
To my excitement, after some finessing, it worked quite well. But what really surprised me was when I played the output side by side with actual landing footage: it lined up very very well.
To me, this means one of two things: either I got incredibly lucky, or SpaceX is running a very similar optimization on their actual system. I think both are true.

🤖 China's Zhurong rover makes history with Mars landing
China's Zhurong rover touched down on Mars early Saturday, state media reported.
The 1.85 meters tall rover is solar-powered and has a mass of around 240 kg, making it far smaller than the huge, 1,025-kg radioisotope-powered Perseverance but larger than NASA’s earlier Spirit and Opportunity rovers.
The six-wheeled rover has a top speed of 200 meters-per-hour and was tested out at a site built by the China Academy of Space Technology. The rover carries six science payloads to study the topography, geology, soil structure, minerals and rock types and atmosphere in the area:
▫️ NaTeCam: A pair of 2048 × 2048 pixel navigation and terrain cameras.
▫️ MSCam: A multispectral camera installed on the mast between the NaTeCams to provide information on surface materials.
▫️ MarSCoDe: The Mars Surface Composition Detector includes a laser-induced breakdown spectroscopy (LIBS) spectrometer.

💻 12 common attacks on embedded systems
Interesting article that sums up the most popular attack types on embedded systems.
Software-based attacks: target the brains of the system — the application that manages the devices. A successful attack on software allows a hacker to access data or gain control over an embedded system. Searching for vulnerabilities in software design and code is the most popular vector of attack because it’s possible to conduct such an attack remotely.
Network-based attacks: exploits network infrastructure vulnerabilities and can also be performed remotely. Using these vulnerabilities, hackers can listen for, intercept, and modify traffic transmitted by an embedded system.
Side-channel attacks: intend to use hardware security flaws in embedded systems to hack them. A side-channel attack is the hardest and most expensive type of attack, as it requires precise knowledge of the hardware design and physical availability of the target system.

🤖 This flying AI robot can pick fruit – preventing waste in the process
Tevel Aerobotics Technologies, has invented a flying autonomous robot (FAR) which uses artificial intelligence (AI) to identify and pick fruit. The robot can work 24 hours a day and picks only ripe fruit.
The innovation was a direct response to labour shortages. “There are never enough hands available to pick fruit at the right time and the right cost. Fruit is left to rot in the orchard or sold at a fraction of its peak value, while farmers lose billions of dollars each year,” the company says.
The FAR robot uses AI perception algorithms to locate fruit trees and vision algorithms to find the fruit among the foliage and classify its size and ripeness. The robot then works out the best way to approach the fruit and remain stable as its picking arm grasps the fruit.

📰 Embedded Vision Sees a Bright Future
Driven by advances in sensors, processors and software, embedded vision is going everywhere – from agriculture to factories, and from autonomous vehicles to professional sports. Even the Covid-19 pandemic has served to accelerate its deployment with vision systems being used in applications like public surveillance, health and safety inspection.
Artificial intelligence (AI) is gaining momentum in embedded vision and image processing applications as developers increasingly apply deep learning and neural networks to improve object detection and classification.
With an increased ease-of-use, lower prices, and smaller devices that fit into existing machineries, embedded vision will be more accessible for smaller companies that haven’t used embedded vision before.

🔋 Cement-Based Batteries May Turn Buildings Into Massive Power Storage Facilities
Chalmers University of Technology (CUT) presented a new cement-based battery that could form the building blocks of entire structures to store energy harvested by renewables.
The CUT team's concrete-based battery does, indeed, have a relatively strong performance. The researchers said that tests showed the battery has an energy density of 7 Wh per square meter of material (or 0.8 Watthours per liter) — 10 times more than previous concrete battery solutions.
The CUT team did note that their research is in its very early stages. One issue that will have to be resolved, for example, is the fact that concrete buildings have an incredibly long lifespan, not matched by batteries.
Despite the drawbacks, the CUT team has already envisioned use cases for concrete battery storage.

🥦 The Future of Farming Is Inside This Bomb Shelter
Deep beneath the streets of London, in a complex of bomb shelters left abandoned since World War II, thousands of green sprouts are being grown from seed without soil or sunlight, in tunnels transformed into a high-tech commercial farm.
Above each growing bench is a round, yellow sensor the size of a large coin that records temperature, humidity, and illumination, and sends the data to the University of Cambridge’s engineering department. The results are fed back to GU, which compares them with the crop yields to determine which conditions are working best for growth.
In the past five years that the farm has been operating, technology has improved a lot—more efficient LED lighting, water recycling, and air management systems.
