The German Do-it-yourself audio magazine “Klang + Ton” was looking for a better audio solution for then Raspberry Pi than USB DAC. They found our HiFiBerry DAC. There is a nice article that explains why the HiFiBerry DAC performs better than USB DACs and how to use it. The new issue should be available in shops tomorrow. You can also buy it in PDF format online.
This is a modification of the Pibow case for the HiFiBerry DAC. We will release the STL files when it is finished for “print-your-own-case”. Only the layers 1-4 can be used without modification, therefore it might be the best idea to print all layers.
Here comes another nice HiFiBerry DAC installation. Jens from Germany doesn’t like switching mode power supplies for audio. Therefore he created a HiFiBerry setup with a huge linear power supply. Note that the power supply needs to provide at least 5V/1A for a stable operation of the Raspberry Pi. Depending on the input voltage this means heat. He uses a large heat sink and a small ventilator to get rid of the heat.
A spanish HiFiBerry Digi user has written a guide how to configure XBMC. If you are spanish-speaking, have a look at it.
The HiFiBerry Digi user “Pretender” has written a very good guide how to use the board to output Dolby Digital and DTS to an external home theater system. This will output the plain AC3/DTS data stream without decoding it on the Raspberry Pi. Check out his guide.
P.S. We expect that this should work out-of-the-box in Raspbmc soon.
Pieter Kleinjahn has installed a Raspberry Pi, the HiFiBerry DAC, some buttons and a LCD display in one box.
The buttons can be used to control MPD. Distributions like Volumio and RuneAudio are based on MPD, therefore this could be interesting for many readers. Peter has provided the Python script that controls everything. You can download it here: mydisplay-20140409. Note that we provide this “as is” without any support. However, the code is clean and well-documented. Therefore it should be relatively easy to adapt it to your needs.
The Raspberry Pi foundation has announced the “Raspberry Pi compute module”. As we are big fans of the Raspberry Pi, this looks like an interesting product to us. However, let’s have a closer look first.
The product is clever for the Raspberry Pi foundation. Many of the Raspberry Pis sold already are not used by private persons, but in industrial applications. The good availability and the low price of the Raspberry Pi made it a nice platform for these many applications. With the new board, the foundation clearly targets this market.
The compute module basically consists of the Broadcom SoC chip and a 4GB flash. The 4GB flash is really nice, because you don’t need an SD card with this module. All other hardware that is included in the Raspberry Pi Model B is missing. The most critical: there is no ethernet controller. Using a standard SO-DIMM module is good for large producers, but for small quantities this increased costs again. Also there is no voltage regulator on the board, which means you need external 3.3V and 1.8V voltage regulators. Therefore solutions based on this board won’t be cheaper, but most likely more expensive than solutions based on the Raspberry Pi.
Some people where already dreaming about clusters of compute nodes for computing applications. I don’t think this is a good idea. If you’re really looking for CPU performance, the Raspberry Pi is not the first choice. There are many other ARM based SoCs available, that provide much better performance and are only a bit more expensive.
