Altay Brusan, Aytac Durmaz - Git for Electronic Circuit Design CAD and Version Control for Electrical Engineers (2022)

Work with Git and avoid dangerous mishaps in this popular, cooperative environment, even if you have no software engineering background or previous experience with Git.

Once you understand the basics of Git, you’ll design a digital system circuit using a computer aided design (CAD) tool. You’ll learn to collaborate effectively through Git between team members, incorporate continuous development philosophy, work with project documentation, and build a solid project structure. Finally, you'll see how Git can also ease maintenance tasks and provide CAD designers unique opportunities.

What You'll Learn:
Work with the Git-bash environment
Incorporate continuous development philosophy
Discover the links between Git and modern CAD programs

OBJEX Link - open-source development board based on ESP32

OBJEX Link is a modular IoT board. It is designed to develop IoT devices that are easy to repair and recycle. OBJEX Link is designed to meet a wide range of uses: Smart Home & Cities, IIOT, Everyday things & Wearables, Predictive Maintenance, Agriculture Automation.

OBJEX Link can also be used for rapid prototyping, and developing research and robotics projects, with the right module you can extend the possible uses of the board.

The compact form factor and board design ensure easy use and maintenance of the board. The architecture of OBJEX Link is composed of two parts, the first is the mainboard (OBJEX Link) and the second is the module allows for easy customization and interfacing with hardware compared to other IoT boards.

How to Debug an Arduino Project

Debugging is a vital element of the creative process when it comes to developing code. However, debugging in Arduino IDE be difficult as it does not include a specialized debugging tool.

Arduino IDE Pro has a debugging tool that can be used to enhance debugging skills. It has the following features which make it very useful to the developers: code indentation, block folding, auto-closing brackets, comment toggling, etc.

Visual Micro is a Microsoft Visual Studio plugin that allows you to develop cross-platform Arduino applications. Visual Micro also provides GDB debugging, as well as serial, Bluetooth, and Wi-Fi debugging.

DebugWire is an Atmel protocol that allows you to debug multiple ATTiny (e.g., ATTiny 13, 85) and ATmegas (e.g., ATmega48/88/168/328) without using JTAG and just using the Reset pin.

Atmel Studio IDE is a free environment that provides competitive debugging capabilities to assist in the resolution of code problems.

What are best practices for IoT system security?

Fierce Electronics reached out to experts on their best practices:

The latest software is the most secure. That’s because it addresses currently known threats (CVEs or Common Vulnerabilities and Exposures). CVEs are fixed first upstream (for open source) and in new software releases for proprietary software.
Open-source platforms are open to scrutiny and continually updated to counter latest threats.
A unique Root of Trust should be installed on every device.
ALL software on an end device should be updatable - we don't know what we don't know as we learned with Spectre and Meltdown. This includes secure boot firmware on Arm and BIOS on x86.
Device provisioning should be simple and not involve the end user. This means secure device onboarding.
The OTA (Over the Air) update platform itself must be secure, obviously! This includes The Update Framework (TUF).

Khadas VIM4 Review: Faster Than a Raspberry Pi

There have been many pretenders to the Raspberry Pi’s crown, some good and some bad. But none have managed to throw the Raspberry Pi offs its throne as the go-to single board computer for projects. Khadas’s VIM4 is the latest to make the attempt and it comes so close.

The Khadas VIM4 is an octa-core Arm CPU package with a quad-core Arm Cortex A73 running at up to 2.2 GHz, and a 2-GHz Arm Cortex A53. This is backed up with 8GB of LPDDR4X running at 2016 MHz. But there is something else with the Khadas VIM4. Hidden under the flat heatsink is a 32GB eMMC 5.1 chip which gives us better performance than a micro SD card.

The downside of this Khadas VIM4 is the GPIO. We would love to see full access via Python and other programming languages. Once we have that, then the Khadas VIM4 will be “on par” with the features of the Raspberry Pi, though it will never have the level of support and huge ecosystem of the Pi.

2022-06-12 22:13:28 Shenzhen: The Silicon Valley of Hardware

Examine the unique manufacturing ecosystem that has emerged, gaining access to the world’s leading hardware-prototyping culture whilst challenging misconceptions from the west.

The film looks at how the evolution of “Shanzhai” – or copycat manufacturing – has transformed traditional models of business, distribution and innovation, and asks what the rest of the world can learn from this so-called “Silicon Valley of hardware".

Unofficial TikTok Watch

The custom-built smartwatch that plays TikTok videos. This smartwatch uses a microcontroller called the ESP32 Pico, and is coded using the Arduino Library. The PCB is built using EasyEDA and JLPCB.

Using an unofficial API for Python, we can download TikTok videos then use OpenCV and PyDub to stream the data to the ESP32. On the ESP32 we play that data through an ST7789VW display and max98537a DAC.

What Is Wi-Fi 7 ?

Great capacity, less latency—here's how IEEE 802.11be achieves both

Several new technologies—and some that debuted in Wi-Fi 6E but haven’t entirely yet come into their own—will allow Wi-Fi 7 routers and devices to make full use of an entirely new band of spectrum at 6 gigahertz.

Automated Frequency Coordination (AFC) makes it possible for Wi-Fi 7 networks to operate around incumbents by preventing transmissions in bands that would interfere with nearby weather radar, radio telescopes, or others. At the same time, it frees up Wi-Fi 7 networks to broadcast at a higher power when they know there’s no preexisting spectrum user nearby to worry about.

Multi-link operations (MLO) will take advantage of the fact that Wi-Fi’s existing 5-GHz band and new 6-GHz band are comparatively closer than the 2.4-GHz and 5-GHz bands are to each other. Wi-Fi access points have long had the ability to support transmissions over multiple wireless channels at the same time.

Anemosens – Build a 3D printed wind sensor / anemometer

In order to be able to evaluate the measured values for wind speed and wind direction, author created a small sensor board, which can be integrated into the base in such a way that the sensors are positioned in exactly the right places.

The sensor board can then be connected to an ESP32 via an optional additional board. The data can then be further processed or stored in various ways.
