📟 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.

📃 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.

📟 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.

🎬 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.

📃 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.

📃 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.

📟 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.

📷 ESP32-CAM - Take Photo and Save to MicroSD Card with Date and Time
In this tutorial, you’ll learn to take a picture with the ESP32-CAM and save it to the microSD card. We’ll include the current date and time on the filename. Including the date and time on the filename is useful because each picture will have a unique filename, which means no issues with overwriting existing files; you’ll know when each photo was taken; and it will be easier to organize or retrieve your files later on.
