A HiFiBerry user has written a nice blog post how to build a music player based on the Raspberry Pi and the HiFiBerry DAC. Check out his page!
This is the most advanced HiFiBerry DAC setup we have seen so far. A German user integrated not only the Raspberry Pi and the DAC in a nice enclosure, but also a switching power supply. Power is connected using the onboard header on the HiFiBerry DAC and a USB WiFi Dongle is used for wireless connectivity.
The first test setup of the new Class-D amplifier project works. We have a fully digital connection between the Raspberry Pi and the amplifier. With the right driver (we have to work on this first), volume and also sound processing can be controlled directly from the Raspberry Pi.
Note: Don’t try to connect the output of an Class-D amplifier to an oscilloscope unless you know exactly what you’re doing. Many Class-D amplifiers use H-bridge outputs. In this case none of the output connectors is directly connected to ground. Connecting one of these pins to the ground of an oscilloscope can create a short-circuit and destroy your circuit and in worst case even your oscilloscope!
Here is another nice case that a HiFiBerry DAC user built:
Have a look at the nice details, e.g. the doors hiding the HDMI connector. There are more pictures here: https://www.dropbox.com/sh/xfqtr2hpkhmwfz0/ioV-QRo35g#/
Please do not steal Lego bricks from your children!
Have a look at this nice setup of a Swiss HiFiBerry DAC user. He used an old amplifier and added a Raspberry Pi, the HiFiBerry DAC and a wireless stick to create a very cool streaming audio player.
A HiFiBerry DAC owner built this amplifier with an integrated Raspberry Pi. It has 2 line inputs and the Raspberry Pi + HiFiBerry DAC as sources. Amplification is done by a Class-D amplifier.
