One late night while debugging the serial port, the waveform on the oscilloscope suddenly started doing the mechanical dance— my Python script, after running for 8 hours straight, suddenly read the temperature and humidity sensor as gyroscope data. This reminded me of the I/O multiplexing dilemma Guido van Rossum faced when designing the prototype of … Read more
The tariff countermeasure has reached 125%, and we will no longer play digital games, so there is no point in discussing tariffs anymore. Today, let’s talk about AI toys. Currently, AI toys are somewhat of a pseudo-concept; to be precise, they are still in the explosive stage of AI + toys. Most toys are simply … Read more
🔍 Section One: AI Acoustic Laboratory 🌟 Core Technologies Sound Field Adaptation 📍 Spatial Scanning: Using a microphone array and AI algorithms, it can identify room structures in 0.5 seconds (like Sony’s 360RA technology) and automatically adjust the sound field dispersion angle. 🎯 Emperor Seat Compensation: Even if seated in a corner of the sofa, … Read more
Recently, the Cyber Dog and Xiao Zhi AI have become quite popular on Bilibili. I also wanted to recreate one, preferably combining both, and after some research, I found that the authors’ open-source solutions did not quite match my preferences. I decided to modify them, which led me on a journey of troubleshooting. Reason The … Read more
Arduino programming is a simplified version based on C/C++ language, allowing code to be written and uploaded to the Arduino development board through an Integrated Development Environment (IDE) to control external devices. Its core features are “low threshold and high extensibility”, enabling quick entry even without hardware knowledge.Currently, many programming robots in China are based … Read more
Reference:https://wiki.analog.com/university/tools/pluto/hacking/hardware#schematics Since its release in2017 until the end of the English documentation in2023, the official version has undergone several revisions (Rev). These areA,B,C,D. However, according to the description,C and D are essentially the same. The hardware version number can be found on the device’s built-in webpage; if you findRevC, it means you are actually usingRevD. … Read more
Next, let’s look at the differences between RevC and RevB: 1. In RevB, the relative position of resistor R88 and fuse F1 was incorrect. Additionally, the DC choke (power choke) we added can reduce noise, but it connects PGND and GND. There should be no DC potential difference between these two points. However, under certain … Read more
This may be the most explosive script in the chip industry in twenty years—ARM is wielding legal weapons to pursue its partners worldwide, resembling a real-life version of “Game of Thrones.” Just last month, Qualcomm launched antitrust complaints against ARM across three continents, pushing this battle for architectural hegemony to a boiling point. Meanwhile, Chinese … Read more
Source: IoT Frontier Station For developers, an IDE is an essential tool. However, most powerful IDEs run on x86 architecture, and unless some major companies ensure compatibility with their products, there are few popular IDEs that support other architectures. Unexpectedly, the Raspberry Pi Foundation has recently announced support for VS Code. VS Code has officially … Read more
Source: IT Home Author: Xiao Gongzi The Raspberry Pi Foundation has released a new version of the official Raspberry Pi OS for Raspberry Pi computers, featuring updated components, bug fixes, and various performance improvements. The most significant change in Raspberry Pi OS 2023-05-03 is the kernel upgrade from the long-term supported Linux 5.15 LTS to … Read more
