The first blog gave me a long course design, that is, the topic "3G wireless router. The development platform used in this development project is the Raspberry Pi Development Board. The following is the question ..... Objective: To set Raspberry Pi as a 3G wireless router and access the Internet through Huawei's e261. Tools: Raspberry Pi Development Board, 3G wir

I want to build a Raspberry Pi cluster to serve as the front-end of the website. The website is written in php without a database. I want to know how many Raspberry Pi is required to achieve the same performance as an E3 server (or other pc servers). has anyone done a similar test? I want to build a Raspberry Pi cluster to serve as the front-end of the website. T

ArticleDirectory Introduction Introduction Some time ago, someone posted a Post saying that Raspberry Pi could send FM radio signals, so they all played around and found that the effect was good. So they wanted to expand their functions. Fmemission functions implemented on the Internet have limitations: Only files in WAV format can be played, and wav files must be16 bits 22.5 kHz monoFormat. Only local audio files can be pla

Recently found a fun thing, Lakka, what is it? It is a game simulator, but not those simple game simulator, it can play a lot of games, arcade games, red and white machine games, PS games, such as the synthesizer.A link to the official website: Lakka official websiteAbout Lakka's introduction, the direct official website cut a diagram to explain under:Four points: strong, friendly, low cost, open source!!Friendly on the table now to realize this universal game is too easy! The steps of the offic

DIYA UAV Vision tracking system based on Raspberry Pi and PythonThe drone's image is stored and transmitted to the ground station in real time, which is almost standard. Suppose you want something advanced--to process the captured image directly on the drone and implement your own active control. In fact, visual tracking has been in some high-end consumer-class UAV has the application, just play out of the box and never have their own hands-on;).Some

This article mainly explains Python operation SQLite's specific method, because the online material is numerous, repeats the part no longer repeats only achie

Windows 3.1 is running on a Raspberry Pi, and you naturally want to run Windows 10. So you're ready to install a system of Windows IoT core on the Raspberry Pi. When writing this text, it's not the first time that you've installed Windows IoT core. After I got the Raspberry Pi on my birthday, I immediately tried a Windows IoT Core. Support for the official

Recently I used Raspberry Pi to create a Git private server for all my Git repositories. I spent some time to make everything work correctly, but now it can run. Install Git First, install Git on Raspberry Pi.Sudo apt-get install wget git-core This will install the Git server and necessary client software. Install SSH If you have not installed SSH, run the following command to install it:Sudo apt-get install ssh Run the following command to start it:S

Now so we can hear in the radio spectrum, it's time to explore the possibilities of broadcasting

The PI program on vier gourdon is a good start for computing, piclassic. I downloaded the C program and compiled it with/O2. I found that it is still a little faster than I did without changing my mind. Of course it cannot be compared with the above program. It takes 770 ms, and I have rewritten it to calculate 10000 bits for 465 Ms. It is rewriting rather than rewriting. Visible/O2 is sometimes inferior to manual optimization. When I write this progr

What is Raspberry Pi? You don't know? I went to Baidu, an interesting hardware.

How to Use image effects on Raspberry Pi Now you can use the Raspberry Pi camera module ("raspi cam") to add a variety of image effects to your photos, just like using a card camera. The raspistill command line tool provides a wide range of image effects options for Raspberry Pi to beautify your images. There are three command line tools that can be used to captu

Make full use of the SD card space in Raspberry Pi Generally, a 4g sd or TF card is required to create a system image for Raspberry Pi, but do you know if your SD card is 8g or 16g or larger, after various types of Linux are created and started to enter the system, only SD cards within 4 GB can be used, while the other extra parts are blank and no partition space. This is a big waste. If you want to replace

Starting with the Windows IoT Core 14986 release, Microsoft has added the Cortana voice assistant feature. Before, we could only use local speech recognition, and we needed to write the application to download it to the device. From now on, Microsoft has integrated the Cortana voice assistant from the system level, enabling users to start Cortana and interact with Cortana in real time with system settings. Let's try the process of using Cortana as a Windows IoT core device with Raspberry
