I’m sure you are all aware of the different open source hardware that has become available. These are lightweight small computers that are designed to allow anyone from programmers, hobbyists to school children to start creating.
The RaspberryPI is right up there and has been making some great new versions and setting some amazing records at the same time. The latest 2 versions that have appeared are the PI Zero that costs $5 and is the first computer to be given away on the front of a magazine. This sounds like a gimmick and yes it was a publicity stunt of sorts but it was about the most thought provoking one I have seen in a long time when you think about the implications of a computer that can be given away and the possibilities this opens up. Not only in terms of 3rd world applications but also of the uses for monitoring where a little processing power is needed.
The latest kid on the block is the RaspberryPI3 that has added the long awaited WiFI, Bluetooth 4.1 and BLE. As you can see from the spec below there are lot of possibility that the new PI can be put to.
The Raspberry Pi 3 is the third generation Raspberry Pi.
- A 1.2GHz 64-bit quad-core ARMv8 CPU
- 802.11n Wireless LAN
- Bluetooth 4.1
- Bluetooth Low Energy (BLE)
Like the Pi 2, it also has:
- 4 USB ports
- 40 GPIO pins
- Full HDMI port
- Ethernet port
- Combined 3.5mm audio jack and composite video
- Camera interface (CSI)
- Display interface (DSI)
- Micro SD card slot (now push-pull rather than push-push)
- VideoCore IV 3D graphics core
The Raspberry Pi 3 has an identical form factor to the previous Pi 2 (and Pi 1 Model B+) and has complete compatibility with Raspberry Pi 1 and 2.

And don't forget the Raspberry Pi Zero! It's a tiny version with stripped back connectivity and performance but still capable of running a full proper OS:
Low power demands mean it'd be easy to run off solar or batteries, and the same array of GPIO connections as the big brother Pi make extending it very possible.
