📟 Network Traffic Visualizer At its core, this board design is a simple desk toy that connects an ESP8266 module to a shift register to display data on the 8 blue LEDs. The Arduino sketch measures how many packets are flying around on the ESP's Wi-Fi channel, and displaying the intensity on the LEDs much like a VU meter. The firmware uses the promiscuous mode of the ESP8266 to allow it to capture any packets present on the selected AP Channel. This means that the board can see all the activity on that channel without connecting to any of the networks itself. These packets are like the envelopes of the internet activity: containing the data sent between devices and the internet. By counting how many packets the board sees in a given time interval, it can display the intensity of the network activity on the 8 LEDs using a shift register.

📃 3 Modern Trade-Offs in Embedded Systems Design Every embedded systems developer needs to balance these trade-offs carefully In any system design, there are always trade-offs that need to be made. Unfortunately, there is rarely a time when you can get your cake and eat it, too! Modern embedded systems have exceptionally interesting trades that need to be made that often result in complex choices. The following post explores the three most significant trade-offs facing many teams today: ▫️ Power consumption versus system performance ▫️ Cost versus reliability ▫️ Scalability versus complexity Successfully balancing them will determine whether you successfully launch a product or whether your product and company struggle to succeed.

📃 Decoding Digital Twins: Exploring the 6 main applications and their benefits Research findings from an analysis of 100 digital twin projects The market for standalone digital twin software grew 71% between 2020 and 2022, according to the recently published Digital Twin Market Report 2023–2027. Survey results, also part of this research, indicate strong adoption. For example, 29% of manufacturing companies globally have fully implemented or are implementing a digital twin strategy for a portion of their operational assets, and a further 63% are currently developing or have already developed their digital twin strategy. In the study, researchers identified six clusters of digital twin applications that reflect two-thirds of all digital twin projects today. For instance, 31% of the digital twin projects are focused on prediction at the system level. More information... #articles

🎬 Raspberry Pi 4 RAM Upgrade This video shows how to upgrade the RAM chip on the Pi 4 from 1 GB to 8 GB with help of a hot air gun. These chips are BGA, and those might feel intimidating if you’re just starting out with hot air – however, we recommend you watch this video, as author’s approach is of the kind that brings BGA replacement to hobbyist level. Replacing this chip can get your Pi 4 to the highly-sought-after 8 GB target – as an aside, it is surprising that there was no configuration needed, as the Pi 4 booted right up and successfully recognized the extra RAM added. https://youtu.be/5pW4_nqcIWA #video #raspberry

🔐 The security vulnerabilities in modern cars (BLE Relay Attack) The modern passenger vehicles are essentially highly mobile computers now. The computing systems that control these cars can be relatively easy to break into thanks to manufacturers’ insistence on using wireless technology to unlock or activate them. This particular vulnerability involves the use of a piece of software called gattacker which exploits vulnerabilities in Bluetooth Low Energy (BLE), a common protocol not only for IoT devices but also to interface a driver’s smartphone or other wireless key with the vehicle’s security system. By using a man-in-the-middle attack the protocol between the phone and the car can be duplicated and the doors unlocked. Therefore, the following article explores how these attacks can be performed in practice. More information... #articles #security

📟 DigiCombo - When Digispark Attiny 85 automates your smartphone You no longer need to waste your time on simple and repetitive tasks and you can save it for hard tasks that have a lot of value just only prepare the necessary inputs that include the coordinates and the text to be printed, leaving the rest to Digispark Attiny 85. It uses V-USB and HID protocol for inject touch events and keystrokes that your Digispark recognized by your system as an external touch screen and a keyboard. The operating systems in which it works correctly: ▫️ Android ▫️ Windows 10 It has video examples for Instagram page scrolling, unlock screen brute-forcing with random coordinates, playing the Stack rhythm game, and pinch zoom.

📃 ESP32: Erase Flash Memory (Factory Reset) This is a quick guide showing how to erase the ESP32 flash memory to restore it to its original state. This might be useful if you want to delete any changes made to the firmware or configuration settings; if the system is crashing constantly and you can’t upload new code; to clear data that is no longer needed, and other applications.

📟 Three-axis Accelerometer Data Logger ChatGPT has gained immense popularity recently, and the system has even been down due to a significant surge in usage. To examine its compatibility with gestures, the author has designed this device. The first step is to collect and store data for future model training on TinyML. It has an accelerometer+gyroscope module, which will gather and save the three-axis (x, y, and z) data of hand movements to a microSD card and display them on an OLED screen in real-time. The recorded data then can be used for machine learning applications and training the neural networks. More information... #projects

📃 Performance Evaluation of C/C++, MicroPython, Rust and TinyGo Programming Languages on ESP32 Microcontroller The ESP32 chip is gaining more popularity, both in academia and in the developer community, supported by a number of software libraries and programming languages. While low- and middle-level languages, such as C/C++ and Rust, are believed to be the most efficient, TinyGo and MicroPython are more developer-friendly low-complexity languages, suitable for beginners and allowing more rapid coding. This paper evaluates the efficiency of the available ESP32 programming languages, namely C/C++, MicroPython, Rust, and TinyGo, by comparing their execution performance. The results show that the C/C++ implementations were fastest in most cases, closely followed by TinyGo and Rust, while MicroPython programs were many times slower than implementations in other programming languages.

📟 SeismoM5 - Open-Source Earthquake Sensor SeismoM5 is an Earthquake Sensor Implementation on M5StickC, using its own MPU6886 accelerometer. Although MPU6886 in M5StickC is a bit on the noisy side; disabling Gyro and using an accel calibration helped a little. The properties of this project is: ▫️ Calibrate MPU6886 accelerometer and use calibration results as offsets. ▫️ Use DLPF - 5 Hz. ▫️ Use MQTT and send data, only when an earthquake happens. ▫️ Draw X,Y,Z accel results on M5stickC screen as graph, only when an earthquake happens. ▫️ Show PGA always. ▫️ Emergency alerts; Red Led and SPK HAT sound warning during an earthquake. Usage: Seismologists mount accelerometer based seismic sensors to the lowest point of the structure, close to the ground as possible. However, since this is an amateur earthquake sensor, you could mount it as high as possible in the house, on a wall. More information... #projects #sensors

📰 The US Air Force successfully tested this AI-controlled jet fighter An autonomous jet fighter has now completed 17 hours of flight testing, including advanced fighter maneuvers and beyond-visual-range engagements, according to the United States Air Force. "After training our AI-driven autonomy agents using high performance computing and modeling and simulation, it is critical that we fly these agents to validate the difference from the simulator to live flights. Having an aircraft like the X-62 is critical to rapid flight testing of these autonomous behaviors," said an Autonomous Air Combat Operations official. During the flights, a human pilot was on board, able to take over should it be necessary. More information... #news #artificial_intelligence
