Five unique uses for the Raspberry Pi
Recently, I heard someone on a conference call say that the open source community is a combination of curiosity and a culture of problem-solving. Curiosity is the basis of our problem solving. When solving problems of all sizes, we use a wide range of open source tools, including Linux running on the incredibly convenient Raspberry Pi.
Because each of our life experiences are unique, I asked our community of authors about the most unusual Raspberry Pi uses they’ve come across. I have a feeling these amazing builds will inspire others.
Experimenting with the Raspberry Pi
To me, the Raspberry Pi is a great tool for adding additional development resources to my home network. If I want to create a new website or try out a new software tool, I don't have to clutter my desktop Linux machine with a bunch of packages that I may only use once while experimenting. Instead, I'll set it up on my Raspberry Pi.
If I think I'm going to do something risky, I'll use a backup boot environment. With two microSD cards, I can plug one card into the Raspberry Pi and use the second card simultaneously for any experiment I want. While it wouldn't cost much to purchase an additional microSD card, it would save a lot of time when I want to do a second mirroring experiment. Just a simple operation, shut down and replace the microSD card, restart and you can start using the dedicated test system immediately.
My Raspberry Pi acts as a print server, connecting my non-WiFi printer to my home network when I'm not experimenting. This SSH file server is very convenient and helps me quickly back up important files.

The popularity of the Raspberry Pi
The most surprising thing I’ve seen about the Raspberry Pi is that it makes small single The concept of tablet computers became popular and popularized, making it truly practical for the masses.
Before the Raspberry Pi, we had similar small single-board computers, but they tended to be niche, expensive, and prohibitive from a software perspective. No matter how difficult it is to obtain right now, the Raspberry Pi is so affordable that anyone can easily get one for a project. Once it became cheap, people would overcome the software challenges to make it good enough to solve many basic computing tasks, and even use a full real computer for a specific task, not just a microcontroller.
We have an abundance of good, relatively inexpensive small single-board computers, which facilitates all kinds of debugging, playing, and experimentation. People were willing to try new ideas, and there was even a push for more hobbyist hardware development to support those ideas.
Honestly, this is the most amazing and radical thing I’ve seen from the Raspberry Pi: it fundamentally changes people’s perception of computing, especially in the areas the Raspberry Pi excels in, Not only has it spawned its own ecosystem, it has now spawned countless other diverse ecosystems.
Bee's Raspberry Pi
My brother and I held a beehive breeding project in 2018, using trees Raspberry Pi and various sensors monitor beehive temperature and humidity. We also plan to implement a beehive scale in the summer to observe the honey production of the bees, and measure the weight in the winter to see if the bees have enough food. However, we ultimately did not implement this plan.
Our small monitoring solution is based on a Raspberry Pi 2B, running Raspbian Stretch (based on Debian 9), with a temperature and humidity sensor (DHT11) connected. Inside the hive we have three to four of these sensors measuring the temperature at the entrance hole of the hive, under the lid and on the lowest frame. We connect the sensor directly to the Raspberry Pi and read the data using the Python_DHT sensor library. We also built InfluxDB, Telegraf, and finally Grafana to visualize the data.
If you want to know more about our setup, we published an article about our small monitoring solution in Linux Magazine.
Retro Computing with Raspberry Pi
I am hoping to create a project using a Raspberry Pi that simulates how to program machine language into an old school computer using "switches and lights". This seems fairly simple using the Raspberry Pi's GPIO pins. For example, their online manual shows how to use GPIO switches to turn an LED on or off, or use buttons for input. I figured just a few LEDs and switches, plus a small program running on a Raspberry Pi, would be enough to emulate an old computer. However, I lack free time to work on such a project, that's why I wrote Toy CPU to simulate it.

Building toys with a Raspberry Pi
When my daughter was four years old, she asked to get her one for Christmas "Megalodon Music Box". She could picture it perfectly in her mind. It would be pink and sparkly, with her name on it. When she opens the box, the theme song from the hit movie plays. She can keep the Megalodon and other treasures in the box. After searching everywhere online and in stores, I found none that could match her vision. So my husband and I decided to make a DIY toy store in his home office. And at the heart of it all, of course, is the Raspberry Pi. He uses light sensors and Python scripts to automatically play music at the right time. Based on her aesthetic, we carefully placed the technology equipment at the bottom of the music box and decorated it. That year, open source technology made Christmas magic possible!

Unable to log in to mysql as root
Apr 08, 2025 pm 04:54 PM
The main reasons why you cannot log in to MySQL as root are permission problems, configuration file errors, password inconsistent, socket file problems, or firewall interception. The solution includes: check whether the bind-address parameter in the configuration file is configured correctly. Check whether the root user permissions have been modified or deleted and reset. Verify that the password is accurate, including case and special characters. Check socket file permission settings and paths. Check that the firewall blocks connections to the MySQL server.
C language conditional compilation: a detailed guide for beginners to practical applications
Apr 04, 2025 am 10:48 AM
C language conditional compilation is a mechanism for selectively compiling code blocks based on compile-time conditions. The introductory methods include: using #if and #else directives to select code blocks based on conditions. Commonly used conditional expressions include STDC, _WIN32 and linux. Practical case: Print different messages according to the operating system. Use different data types according to the number of digits of the system. Different header files are supported according to the compiler. Conditional compilation enhances the portability and flexibility of the code, making it adaptable to compiler, operating system, and CPU architecture changes.
【Rust Self-study】Introduction
Apr 04, 2025 am 08:03 AM
1.0.1 Preface This project (including code and comments) was recorded during my self-taught Rust. There may be inaccurate or unclear statements, please apologize. If you benefit from it, it's even better. 1.0.2 Why is RustRust reliable and efficient? Rust can replace C and C, with similar performance but higher security, and does not require frequent recompilation to check for errors like C and C. The main advantages include: memory security (preventing null pointers from dereferences, dangling pointers, and data contention). Thread-safe (make sure multi-threaded code is safe before execution). Avoid undefined behavior (e.g., array out of bounds, uninitialized variables, or access to freed memory). Rust provides modern language features such as generics
What are the 5 basic components of Linux?
Apr 06, 2025 am 12:05 AM
The five basic components of Linux are: 1. The kernel, managing hardware resources; 2. The system library, providing functions and services; 3. Shell, the interface for users to interact with the system; 4. The file system, storing and organizing data; 5. Applications, using system resources to implement functions.
How to solve mysql cannot be started
Apr 08, 2025 pm 02:21 PM
There are many reasons why MySQL startup fails, and it can be diagnosed by checking the error log. Common causes include port conflicts (check port occupancy and modify configuration), permission issues (check service running user permissions), configuration file errors (check parameter settings), data directory corruption (restore data or rebuild table space), InnoDB table space issues (check ibdata1 files), plug-in loading failure (check error log). When solving problems, you should analyze them based on the error log, find the root cause of the problem, and develop the habit of backing up data regularly to prevent and solve problems.
Where is the C language function library? How to add the C language function library?
Apr 03, 2025 pm 11:39 PM
The C language function library is a toolbox containing various functions, which are organized in different library files. Adding a library requires specifying it through the compiler's command line options, for example, the GCC compiler uses the -l option followed by the abbreviation of the library name. If the library file is not under the default search path, you need to use the -L option to specify the library file path. Library can be divided into static libraries and dynamic libraries. Static libraries are directly linked to the program at compile time, while dynamic libraries are loaded at runtime.
Can mysql run on android
Apr 08, 2025 pm 05:03 PM
MySQL cannot run directly on Android, but it can be implemented indirectly by using the following methods: using the lightweight database SQLite, which is built on the Android system, does not require a separate server, and has a small resource usage, which is very suitable for mobile device applications. Remotely connect to the MySQL server and connect to the MySQL database on the remote server through the network for data reading and writing, but there are disadvantages such as strong network dependencies, security issues and server costs.
Solutions to the errors reported by MySQL on a specific system version
Apr 08, 2025 am 11:54 AM
The solution to MySQL installation error is: 1. Carefully check the system environment to ensure that the MySQL dependency library requirements are met. Different operating systems and version requirements are different; 2. Carefully read the error message and take corresponding measures according to prompts (such as missing library files or insufficient permissions), such as installing dependencies or using sudo commands; 3. If necessary, try to install the source code and carefully check the compilation log, but this requires a certain amount of Linux knowledge and experience. The key to ultimately solving the problem is to carefully check the system environment and error information, and refer to the official documents.
