The Culprit Raspberry-Pi
What is a Raspberry Pi? A small, inexpensive computer the size of a deck of playing cards Uses your old computer's monitor, keyboard and mouse Intended as an educational tool to teach computer and computing fundamentals Keeps the learner off the family computer
What is a Raspberry Pi continued. . . (The Wiki answer…. ) The Raspberry Pi is a low cost, credit-card sized computer that plugs into a computer monitor or TV, and uses a standard keyboard and mouse. It is a capable little device that enables people of all ages to explore computing, and to learn how to program in languages like Scratch and Python. It’s capable of doing everything you’d expect a desktop computer to do, from browsing the internet and playing high-definition video, to making spreadsheets, word-processing, and playing games. What’s more, the Raspberry Pi has the ability to interact with the outside world, and has been used in a wide array of digital maker projects, from music machines and parent detectors to weather stations and tweeting birdhouses with infra-red cameras. We want to see the Raspberry Pi being used by kids all over the world to learn to program and understand how computers work.
So What does thing do Really? 1. 2. 3. 4. Ok, it’s a neat little Linux Computer It’s really Cheap! Its incredibly flexable I runs under a highly stable OS. (Much more stable than Microsoft. Ugh… 5. Did I mention its cheap? 6. Its everywhere. 7. Its easy to get. (amazon, etc. . . ) 8. Its small enough to run anywhere. 9. The software is free! 10. There apps for almost everything.
What can Pi do? Browse the Internet E-mail Office Applications (Libre Office suite) Play Music & Videos Display Photos Print Connect USB devices (e. g. Wi. Fi, Flash Drives, Webcams, etc. )
What else can Pi do? Develop Electronics projects Create programs in various languages Control devices like cameras, lights, 3 D printers Lots more!
How much does a Raspberry Pi Cost? About $35. 00 Yes…. $35. 00 But as always there’s always a catch!
You’re gonna need other stuff! The Basics…. And Also…. The catch is the monitor has to be an HDMI compliant Monitor. Sorry, that’s how they built them…. .
But after some initial Configuration… You can run your Pi in “Headless Mode”. Ok, Maybe not that kind of headless. Maybe this kind…. Which just means…. Minimal Connections. No keyboard, Mouse or Monitor attached. Everything runs via Telnet, or VNC
Software in Raspian (Default - version of Debian Linux) Other Op. Sys available including Windows 10 Libre Office Suite Program Languages (Python, Sonic Pi, Scratch, Wolfram, etc. ) Web Browser, Email, Text Editor, PDF viewer, Image viewer, File Manager, Terminal, Calculator, Music and Video Players, etc. Games
OK So How did all this get started? The story begins with a couple of Engineers and Educators discussing how most students have no idea how a modern computer works. Oh they’ll tell you they know all how to use an “Xbox” or “Nintendo Wii” or some other such thing. But they had absolutely no idea how the inner workings of a modern computer are configured. No idea of the hardware involved or how it was interconnected. (What’s a bus? Ram? Rom, Eprom? Or what the heck is I/O) They had no programming skills, not even any basic electronics skills.
So…. They Went to work! The Raspberry Pi launched in 2012, and there have been several iterations and variations released since then. The original Pi had a single-core 700 MHz CPU and just 256 MB RAM, and the latest model has a quad -core 1. 4 GHz CPU with 1 GB RAM. The main price point for Raspberry Pi has always been $35 and all models have been $35 or less, including the Pi Zero, which costs just $5.
