Raspberry Pi (ie Raspberry) is a single-board computer based on a Linux system (Debian, Archlinux), which only has a credit card size, available for spreadsheet making, text processing, game, HD video playback. It is developed by the UK's Raspberry PI Foundation, with a low-cost hardware and free software to stimulate the basic computer science education in schools. It is equipped with an ARM architecture processor, and its computing performance is similar to the smartphone. In terms of interface, the Raspberry Pi provides a USB interface, a fast Ethernet interface, an SD card expansion interface, and an HDMI HD video output interface. Many raspberry PI projects have now appeared, an article on JaxEnter pointed out the 5 major projects based on Raspberry Pi in 2014, now conducting a comprehensive combing for readers to read and reference The specific content is as follows:
Raspberry glasses
The cost of Raspberry glasses is approximately $ 100, which consists of 8 components that include a liquid crystal display and a Raspberry P camera board. Raspberry glasses use only some inexpensive components and use the python script and display images through the display.
Mechanical MEARM
The cost of the robot MEARM is approximately $ 80, which consists of 7 components, which can replace someone to do something. MEARM is an open source that implemented a robot arm that implemented by Raspberry Pi. MEARM only uses A4-sized acrylic plates and 4 inexpensive servo motors. According to the author leak, the design purpose of the project is to help educational teaching or more accurately say it is just a toy.
EEG headset
The cost of EEG headphones is approximately $ 150, which consists of three components. The headset is liberating the human hand, and even a robot. The user can control the music player with only the headset. The principle of EEG headphones is to control music players using Raspberry PI and EEG sensors (read human brain waves). For example, when the user wears a headset listening to the song, once the song you don't like, the player will skip the first song.
Classic arcade game
The cost of the classic arcade game (RASPBERRY PI VINTAGE ARCADE) is about more than $ more than $ 100, which consists of 15 components, including arcade remote sensors and buttons. In the case of the SD card without the Raspberry PI B +, the project can carry about 1200 games. The project uses the game system emulator Pimame, some buttons, and the operating rod (order) and some woodworking techniques. It can be said that the classic arcade game of Raspberry Pi is no longer a simple amateur project.
DIY smart home
The cost of smart home is currently unknown, which may be cheaper than Nest, which consists of 22 components, including sensors and microcontrollers, which may be the most complex, non-professional Raspberry PI project. Users If you want to build your own smart home by using the guide, he must know the Bootstrap and Arduino and related nodes of Python, PHP, MySQL, Twitter. The project uses low-power node networks that can transmit various signal data, such as temperature, humidity, and real-time video feedback to the central station.
The biggest feature of Raspberry Pi is cheap, suitable for users such as computer amateur enthusiasts, teachers, primary school students, and small businesses. Manufacturers and large organizations supporting Raspberry Pi have Minecraft, Walfram Research, Oracle, XBMC Foundation, etc. In China has ICKEY (China's official authorization agent), E Rong (Raspberry Pi Official Cooperation Distributor), RS (RASPBERRY PI Official Cooperation Distributor) and other domestic channels.
