🤖 Mars Perseverance Rover Replica with Arduino
In this tutorial you will learn how to built a replica of the Mars Perseverance Rover. Inspired by the real rover which is currently exploring Mars, I designed this rover in a way that everyone who love this technology, students, makers, mechatronics or robotics enthusiast, and so on, can easily follow the instructions in this video and build their own Mars Rover.
Let’s take a look at the main features of this rover. It employs a rocker-bogie suspension which allows the rover to run smoothly on uneven terrain and climb obstacles, such as rocks, that are up to twice the wheel’s diameter in size while keeping all six wheels in contact with the ground all time.
In order to efficiently steer the rover and avoid tire slipping when driving around a curve, we are implementing the Ackermann steering geometry. With this geometry we can calculate the speed and angle of each wheel depending on the turning radius.

📰 Learning from the global chip shortage
The chip crisis is bound to persist at least until the second quarter of 2022, according to research firm Gartner. The time it takes to produce a single semiconductor might increase by six months, with more complex ones requiring up to a year to be completed.
This will continue to have disastrous consequences in the production and supply of devices containing touch screens, fingerprint sensors and microcontrollers, impacting sectors as diverse as gaming, security, home appliances and automotive.
The good news is that with every challenge comes a lesson. Governments worldwide are spurring initiatives to increase semiconductor self-sufficiency and diversify the supply chain.
In the US, manufacturing giants such as Amazon, Google, Apple and Microsoft have founded the Semiconductors in America Coalition (SIAC), while the EU is heavily investing in new facilities and equipment, aiming to produce 20% of the global chip supply by 2030.

🚗 How Software Is Eating the Car
Good article about the latest trends in automotive industry and development of electronics and software in modern cars.
The semiconductor shortage has placed an intense spotlight on the auto industry’s reliance on the dozens of concealed computers embedded throughout vehicles today.
Ten years ago, only premium cars contained 100 microprocessor-based electronic control units (ECUs) networked throughout the body of a car, executing 100 million lines of code or more.
Today, high-end cars like the BMW 7-series with advanced technology like advanced driver-assist systems (ADAS) may contain 150 ECUs or more, while pick-up trucks like Ford’s F-150 top 150 million lines of code.
Even low-end vehicles are quickly approaching 100 ECUs and 100 million of lines of code as more features that were once considered luxury options, such as adaptive cruise control and automatic emergency braking, are becoming standard.

🧠 Techniques for studying books more effectively
I developed an elaborate and carefully-specified system of shorthand notation to represent causal, temporal, and physical structures. It used Newick notation for tree structures, variants on arrow signs to articulate causation, sequence, combination, and more, templates to rewrite the stereotyped information presented by textbooks in a uniform format, and hyperlinks in Obsidian to represent the relationships between concepts.
The rigid structure of my note-taking approach gave me clear guidance on what it means to "read" or "study" a textbook chapter. The idea of bringing together any data, formula, charts, or techniques I needed to solve a problem, and then making a plan of attack before setting to work, was a big upgrade for my accuracy and sense of ease.

📟 Raspberry Pi Matrix Cube Takes LEDs to a New Dimension
Matrix panels are awesome to play with using a Raspberry Pi but why limit yourself to a 2-dimensional plane? This maker, known as M4ngolicious online, is using six panels of 64 x 64 pixels, 24,576 pixels in total, to create a portable, wireless matrix cube.
M4ngolicious designed and 3D printed custom frames for each panel along with internal structures for mounting the hardware inside. The top panel even has magnets glued into place so it can be removed to access the internal components.
In the project, M4ngolicious is using 2200mah 3S 30C LiPo battery and two YPG 20A SBEC step down converters. The battery can last between 15 and 30 minutes but will vary depending on how bright the output is while in use.

💻 Python vs. C/C++ in Embedded Systems
The article covers the merits and drawbacks of these programming languages and explains why Python can become a serious competitor in embedded systems for C.
The Case For Python:
▫️ Automated testing. Python provides developers with automated testing due to its ability to control tools that send and receive information from the embedded system.
▫️ Data analysis. The ability to receive and store information from the embedded system allows programmers to use Python to develop methods for real-time data visualization.
▫️ Easy-to-learn.
▫️ Extensive libraries.
▫️ Doesn’t use pointers in comparison to C. It lets developers manage the problems in the code easier.
The Case For C/C++:
▫️ Runtime speed. These languages don’t need to interpret the code at runtime.
▫️ Code is easy to control making the language highly-efficient.
▫️ More compact programs. It is crucial as embedded devices usually have little memory and lower-powered CPUs.

🔌 Shine Turbine: Foldable Turbine Puts Wind Power in Your Backpack
It can harvest three phones worth of power in as little as an hour
Shine Turbine, a 3-pound, 40-watt wind turbine that can charge handheld electronics, is the first of a series of renewable power devices designed by the startup to provide freedom from the electrical grid.
The team had to overcome several engineering challenges to get its design right since there were many variables contradicting each other. It had to be durable enough to use as an outdoor product but also lightweight and compact to be easily carried around, and also efficient enough to generate lots of power. This all meant it had to be highly engineered.
When wind speeds double, power output increases eightfold, and when you combine this with Shine's patent-pending technology (high-efficiency blades and lightweight design), you get yourself a wind charger that can provide the most energy for the least amount of weight.
