Slice

Slice is a media entertainment unit founded by Five Ninjas created using the Raspberry Pi compute module as a core component. It is an easy to use, efficient and open-source software and hardware that can be used to watch your favourite movies, listen to songs or even stream from the net. The design includes an elegant lighting system around the box which has ports for USB, HDMI and mini HDMI. It also has an inbuilt hard disk of 1TB so that the media is portable and you can take it easily to anyplace. Simply plug it into a TV through HDMI and it plays, no hassles involved. Media insertion is just drag-and-drop and the Slice will automatically get extra information and shows them.

It is crafted with a fully anodised case made of solid and high quality aluminium. It also provides a unique LED lighting system that provides a band of light that can react to the music as well as visual feedback on the power states and playback. The heart of the Slice is the Raspberry Pi compute module which runs the XBMC and a newly modified computer interface. It contains ports for ethernet, USB, HDMI, Infrared remote support and a large internal hard drive for storage.

The way to use it is simple and its quick to get ready from out of the box. Simply connect to your own computer, then drag and drop your media to it. Slice will automatically get the artwork and extended information and displays it to the viewer when its turned on. It can also show high resolution images and photos. It can even act as an Airplay receiver and enables you to stream audio and video from your iOS device such as iPhones and iPads.

Variants of Raspberry Pi:

rpi circuit boards

There are four main types of the Raspberry Pi, namely the Model A, Model B, Compute module and Zero with three generations namely 1, 2 and 3. The main difference between them is the extra ports available (for example USB, HDMI, Ethernet, etc.) for usage. All have a ARMv6 32-bit processor except for the second and third generation in which the second generation uses an ARMv7 32-bit processor and the third generation uses ARMv8 32-bit or 64-bit processor. There are also types as A+ and B+ but they are just different with form factors. Attached is a picture of the various variants, except for Raspberry Pi 3.

 

Components of Raspberry Pi:

The following components are in the Raspberry Pi 3 with a subset of them in the previous generations:

  1. ARM CPU/GPU - a Broadcom system that has a CPU and a GPU put together.
  2. Wifi and Bluetooth module - The major difference of the Raspberry Pi 3 from its predecessors.
  3. GPIO - These are general input and output points that can be virtually used for all miscellaneous works for the real project users. It can get connected to the sensors, motors and so on.
  4. RCA - This jack is used to connect to an analog TV or any other devices of the similar nature.
  5. LEDs - Light Emitting Diodes if any form of visual feedback is needed
  6. USB - The connection for the peripheral devices. In this aspect, the model A has one USB port while the model B has two USB ports. You can connect the keyboard and mouse to these ports.
  7. HDMI - This port enables users to connect High definition TV monitors or similar devices.
  8. Power - This is where the power is supplied to the board. It requires a regular 5V micro USB charger that is common for smart phones.
  9. SD card slot - This is the "hard disk" of the computer since this is where the Pi boots up the operating system. A full size SD card with the OS is connected here.
  10. Ethernet - This allows the Pi to be connected to the net via wired networks.
