Raspberry Pi - The Tiny & Ultra-Cheap Computer

The Raspberry Pi is a series of small single-board computers developed in the United Kingdom by the Raspberry Pi Foundation to promote the teaching of basic computer science in schools and in developing countries.

The original model became far more popular than anticipated, selling outside of its target market for uses such as robotics.

The Raspberry Pi is a great tool for learning about robotics and controlling it's hardware with code. From single robot arms to fully-functional vehicles, there are many tutorials on the subject available online.

Pi Drone

If you are adventurous you can make a remote-controlled drone using a Raspberry Pi. The Pi also can have a camera to be connected,so you can set your drone to broadcast video to a controlling device.

Smart Mirror

By a smart Mirror you can access a number of functions projected onto a standard mirrored surface and can be a great way to inject a smart device into your daily life.

Home theatre PC

It allows you to create an always-on, low-power entertainment solution with Internet connectivity and endless customisation options.

You can use your Pi home theatre to watch YouTube videos, Twitch streams, read the news, and much more.

Maker creates a Raspberry Pi-powered smart watch running Windows 98!

A genius maker has taken a Raspberry pi A+ and he created his very own smart watch running windows 98. He created this using the emulation software QEMU to run the operating system, a small TFT screen for display and a LiPo battery to power this smart watch.

The Raspberry Pi turned five on Tuesday and the Foundation behind the computer has given us all a present: a new “Pi Zero W” model.

The Pi Zero emerged in November 2015 at the low, low price of US$5. That small sum bought you a 65mm x 30mm x 5mm package containing a Broadcom BCM2835 processor, 512MB RAM, an HDMI connector, SD card slot, two Micro USB ports and the same GPIO pinout as Raspberry Pi 2. But no networking. 

The Pi Zero W fixes that, adding 802.11n Wi-Fi and Bluetooth 4.0 to make it easier to hook the computer up to the world. The Cypress CYW43438 wireless chip used in the Raspberry Pi 3 Model B has been deployed for the Zero W. 

The new model also packs the following kit onto its slim, single-sided board: 

1GHz 32-bit single-core ARM-compatible Broadcom BCM2835 CPU 


Mini-HDMI port

Micro-USB On-The-Go port

Micro-USB power

HAT-compatible 40-pin header

Composite video and reset headers

CSI camera connector

How much would you expect to pay for all that? It turns out that adding the wireless bits doubles the price to a wallet-flattening (not) $10.

The Pi foundation suggests the addition of Bluetooth is aimed at making it easier to connect input devices so that the computer can be hidden away rather than tangled up with wires to keyboards and mice. 

In the video below, the Pi guys say they've made 80,000 of the new model and are cranking them out at the rate of about 25,000 a week. You may therefore find your local distie has some, or none, given the usual burst of enthusiasm for any new rPi model. 

The foundation also notes, in the post announcing the new model that all Pi models have now sold over 12 million units. Quite a feat, no? 

Built on the latest Broadcom 2837 ARMv8 64bit processor the Raspberry Pi 3 model B is faster and more powerful than its predecessors. It has improved power management to support more powerful external USB devices and now comes with built-in wireless and Bluetooth connectivity. To take full advantage of the improved power management on the Raspberry Pi 3 and provide support for even more powerful devices on the USB ports, a 2.5A adapter is required. Made in the U.K. supplied under license by RS components.

Raspberry Pi 2 Model B 1GB Technical Specifications


Get personal with your Pi. Welcome to the Raspberry Pi™ 2, the single board computer that thinks it’s a home PC. Enhanced Quad Core Processor and 1GB RAM now provides you with the opportunity to: 

# Build your own workstation – create and manage your documents and spreadsheets with ease using LibreOffice™
# Faster and more enjoyable gaming – experience less lag and more seamless gaming in all your favourites. Can’t wait to demolish buildings in Minecraft™, trigger your TNT now and be amazed by the results!
# No more buffer face – boots up Raspbian in less than half the time as the Model B+
# More power for your favourite projects – create Space Progammes, Time Lapse Videos, GPS tracking, HD audio and lots more with a full ecosystem of supporting accessories.
# All your previous Raspberry Pi projects are 100% backward compatible with the new Raspberry Pi 2 Model B 1GB 

Technical Specifications:

# Broadcom BCM2837 Arm7 Quad Core Processor powered Single Board Computer running at 900MHz
# 40pin extended GPIO
# 4 x USB 2 ports
# 4 pole Stereo output and Composite video port
# Full size HDMI
# CSI camera port for connecting the Raspberry Pi camera
# DSI display port for connecting the Raspberry Pi touch screen display
# Micro SD port for loading your operating system and storing data
# Micro USB power source

 Raspberry Pi 2 Model B Features:
# Broadcom BCM2837Arm7 Quad Core Processor powered Single Board Computer running at 900MHz
# 1GB RAM so you can now run bigger and more powerful applications
# Identical board layout and footprint as the Model B+, so all cases and 3rd party add-on boards designed for the Model B+ will be fully compatible.
# Fully HAT compatible
# 40pin extended GPIO to enhance your “real world” projects. GPIO is 100% compatible with the Model B+ and A+ boards. First 26 pins are identical to the Model A and Model B boards to provide full backward compatibility across all boards.
