Review: Raspberry Pi 2 as Music Streamer

A couple of months back the Hewlett-Packard laptop that served me as a media player decided to leave this world for a better place (the recycling bin). It was February the 2nd, and that same day the Raspberry Foundation announced the all new Pi 2 Model B, with a much improved spec sheet. And no, I did not sabotage my own laptop just to find an excuse to buy a RPi2. The Raspberry Pi is a credit-card-sized single-board computer, the first edition of which launched on February 2012. Since then, more than 5 million of these little buggers have been sold worldwide. Now it might not sound as much but trust me, it is more than enough to get you playing full high-resolution audio files including 2xDSD and DXD! Basic ingredients: One Raspberry Pi2 which can be found on Farnell Element14, RS and several other suppliersOne MicroSD memory card, 8Gb will be more than enough. This is it. Have you noticed that something else is missing? Before that, let me tell you about our secret ingredient. MPad

High Sensitivity Water Sensor on MCP3008 Introduction Background In an upcoming project I am using the MCP3008 to monitor several sensors. Using the MCP3008 An ADC is an analog to digital converter. Value / Max Value * Vref solving for my voltage I get which gives a value of 1.687V. Of course, this makes sense when I want to calculate voltage, but every sensor has a different meaning. Wiring the MCP3008 is straightforward. Pins 1 through 8 are the eight input pins and are referred to as channels 0 to 7. In this project, I have included a simple voltage measurement to demonstrate this concept. Project Overview The Sensor In this project I have connected up two circuits in one. The Phantom YoYo Water Sensor has three pins. The Circuit The circuit to support the sensor is really simple. Project Software The Application The application I created for this project is a Universal Windows Application and shows two meters in the main view. The MCP3008 Library To use it, first declare an class object as follows: private Mcp3008 _mcp3008 = null;

Photo: Justin McManus It is called ''the death spiral'' and it is terrifying power suppliers. At the moment they are awarded price rises to cover the cost of their spending on cables and substations. If power usage slides (as it has been), they are granted further price rises to ensure they can continue to recover those costs. It has not been a big problem because their customers have had nowhere else to go. Energy specialist Lucy Carter of the Grattan Institute outlined the horror scenario for suppliers while launching a new report to be released on Monday about why we are paying too much for power.

''The risk for the companies is that when people get the option of putting solar panels on their roofs and installing batteries and cutting the cord, demand will fall sharply.
