Raspberry Pi is a single-board computer created by the Raspberry Pi Foundation, a charity formed with the primary goal of reintroducing low-level computer skills for children in the UK. The aim is to revive the microcomputer revolution of the 1980s, which produced a generation of skilled programmers.
Raspberry pi is a mini computer that has features similar to most computers, such as programming, office, watching high-resolution video, and so on. Raspi provides USB, LAN, audio jack and HDMI ports for input and output. Just connect the mouse, keyboard, and TV / monitor, then it will work like a computer. The power consumption used is only about 10 watts.
Raspberry pi can also be used to build or control the desired device. For example, making a robot arm with a program that has been created, making games, illustrations, or songs, all using code.
The name Raspberry Pi
The Raspberry name is inspired by well-known vendors who use fruit names (like Apple, BlackBerry, and Apricot). The name Pi is an extension of Python, which is a versatile interpretive programming language. At first Raspberry Pi had the concept of a simple computer that could be programmed with Python.
History of Raspberry Pi
The Raspberry Pi project began in 2006. They want to feel the spirit of being a “pioneer”, as was felt in 1980, when affordable personal computers (PCs) were available to computer enthusiasts. They have concerns about the diminished interest in computer science and argue that the current ICT curriculum is too focused on making word processing, spreadsheets, and databases.
Initially they planned to make a microcontroller-based computer that could boot directly to the Python interpreter prompt. This inexpensive device was created to promote a new generation in the world of programming and development.
Because of the production costs of a system that can work with network capabilities, drivers, etc. into the interpreter, they decided to use a Linux operating system that is flexible and Open Source.
Employees of the Broadcom company, Eben Upton and other figures such as Jack Lang, David Braben, Pete Lomas, Professor Alan Mycoft, and Dr. Robert Mullins founded a charity called “The Raspberry Pi Foundation”. They had the idea to design a System on Chip (SoC) board that was filled with Broadcom ARM11 processor chips, then sold at an affordable price, aimed at the new generation of computer engineers who certainly had great potential.
Initially, their first Prototype Board was only as big as a Flashdisk, which had 1 USB port and an HDMI port. This board also has a MicroSD slot for storing linux OS. This board is too small to add a LAN port, GPIO port, or audio output, which means this board is not suitable for development.
Then they decided to make a board as big as a credit card, and worked with Linux to create an operating system that made it possible to work on a 700MHz ARM1 176JZF-S processor.
December 2011, Raspberry Pi Beta model is able to play 1080p HD video using onboard Videocore IV GPU. This Raspberry Pi model has a micro-USB type power connector, which allows users to turn on this device using an ordinary cell phone charger.
In January 2012, the Raspberry Pi Foundation sold several prototypes on Ebay. It was also announced that 10,000 Raspberry Pi computers were being produced in China. They will be sold through industrial suppliers “RS Components International” and “Premier Farnell” with additional designs for engineers designed by “Element 14”.
After going through these obstacles, Raspberry Pi is finally ready to be sold on pre-order basis. The official launch was held on February 29, 2012 at 6am local time.
Now Raspberry Pi has been produced with various other models, such as Raspberry Pi 2 model B, and the latest is Raspberry Pi 3 model B which was released in February 2016.
That’s all about the history of the Raspberry Pi, for other references such as models, other projects, can be searched via Google. Maybe my next post will discuss the initial tutorial using Raspberry Pi, or other simple projects.
