📃 Soldering SMDs with Hot Plate Tips
The hotplate method is the easiest soldering method for the hobby electronics enthusiast.
The basic process looks like this:
▫️ Apply Solder Paste to all the SMD pads.
▫️ Place all SMD components in the appropriate place.
▫️ Heat up the entire board to melt the solder and solder all parts simultaneously.
▫️ After the board has cooled, fix any solder bridges.
▫️ Solder in the remaining through-hole parts, if any.
The are a few tips to improve the process:
▫️ If you are doing runs of 5+ boards, you will probably want to make a solder paste stencil.
▫️ If you're good with the solder paste, you can lay a thin line of the paste on the pad, and do that for every pad. This is the recommended way, but it can be tricky.
▫️ If you spend money on any part of your setup, get a good pair of tweezers to place SMDs.
▫️ A solder bridge is when solder connects two pins that are next to each other that are not supposed to be connected. Use desolder braid to remove them.

Around the web, there are many DIY reflow ovens, however they have one big downside: they take up a lot of space. So author decided to build a hotplate instead.
The hotplate is fully programmable, so that any reflow profile can be added. The reflow process is then fully automated.
Important parts:
The case is made out of lasercut MDF. The MDF parts only touch the feet of the hotplate, which are significantly cooler (max 60°C) than the top of the hotplate. Everywhere else, the MDF and hotplate are separated by a small air gap.

📰 The acceleration of global chip-crunch
Semiconductor manufacturers rely on neon to control the specialized lasers they use to make computer chips. Right now, it’s not clear whether they have enough time to find and develop new sources of this gas before their backup supplies run out: Chip companies and industry analysts say there’s anywhere between one to six months worth of neon in reserve.
If that runs out, these companies won’t be able to make semiconductors. This means that the worldwide chip shortage — which was expected to end sometime in the next year — could draw out even longer, leading to higher prices, delivery delays, and shortages of critical technology.
A solution to the neon shortage won’t be the end of the chip industry’s problems, though. Even if new sources of neon arrive, the ongoing war could still create a shortage of other critical supplies used for chips. Russia makes a large chunk of the supply of palladium, a metal that’s used in semiconductors and catalytic converters.

💻 C++ Tricks for C Programmers
C++ offers developers modern tools to leverage when designing more reusable, scalable, and portable code.
▫️ Conditional Compilation Using Constexpr: The bane of many embedded code bases written in C is the large numbers of #if / #elif / #else preprocessor directives. Starting in C++ 17, the language introduced the ability for developers to conditionally compile code using constexpr.
▫️ Ranged for Loops: The C for loop has been stuck in the dark ages by not having a simplified range-based option. Starting in C++ 11, an additional version of the for loop was added that makes working with ranged values easier.
▫️ Use Auto: C developers used to use auto to specify a variable that was limited to the current scope. In C++, auto can be a very useful keyword that tells the compiler to automatically assign the datatype for the developer.
▫️ The Spaceship Operator: Just recently, C++ 20 add a three-way comparison operator <=> that can simplify readability and the code.

🎚 Arduino Portenta X8
The new board comes with the same STM32H7 Cortex-M7/M4 microcontroller found in the Portenta H7 boards, but add a more powerful, Linux-capable NXP iMX 8M Mini processor with four Cortex-A53 cores and a Cortex-M4 core, coupled with 2GB RAM and a 16GB eMMC flash.
Arduino Portenta X8 specifications:
▫️ SoC – NXP iMX 8M Mini Cortex-A53 quad-core up to 1.8 GHz,1x Cortex-M4 real-time core up to 400MHz.
▫️ Microcontroller – STMicro STM32H747AII6 Cortex-M7 @ 480 MHz + M4 @ 240 MHz MCU
▫️ System Memory – 2GB LPDDR4
▫️ Storage – 16GB eMMC flash
▫️ I/Os – 2x 80 pin high-density connectors with CAN, PCIe, SAI, MIPI, DSI, SPI, I2S, I2C, UART, PDM
The new board keeps the high-speed connectors but loses the Arduino MKR headers found in Portenta boards. Just like other Portenta boards, the Portenta X8 is part of the Arduino Pro family for industrial and enterprise use, and the board will be selling for 199 Euros or $239 US once it becomes available in mid-April.

📟 ESP32/ESP8266: MicroPython OTA Updates via PHP Server
OTA (Over-the-Air) update is the process of loading new firmware to the ESP32 or ESP8266 board using a Wi-Fi connection rather than a serial communication. This functionality is extremely useful in case of no physical access to the board.
In this project, we’ll show you an example of how you can do OTA updates to your ESP32/ESP8266 boards running MicroPython code via a PHP server.
In summary, you’ll create a PHP server in which you can submit a new code that you want to run on the ESP. When there is a new code/update available, the ESP downloads the new code, reboots, and starts running the newly downloaded code.

📰 A company's new robot can change from four wheel drive to bipedal in seconds
A company called Swiss-Mile has created an innovative robot that combines legs and wheels to create, what they hope, will be the most versatile last-mile delivery robot on the planet. The robot can even transform from a quadruped, well quad-wheel, to bipedal form in a matter of seconds.
Capable of reaching speeds of 13.87 mph, this diminutive little robot has been developed over the last five years to be incredibly versatile and efficient. It can carry a variety of payloads including tools, materials, goods, and sensors, up to a maximum capacity of 110 pounds.
Since the robot is able to "stand up" it can use its front legs as arms, grab packages, and puts them in its cargo compartment all by itself. Other drones and delivery robots may require human input for some, or all, of these kinds of tasks. The company claims the robot is 83 percent more efficient than legged systems.
