We received a lot of pictures of DIY HiFiBerry projects. We will show some of them here from time to time. However, there are more than we can show here. Therefore we have started a “user gallery” on our HiFiBerry website. Have a look at it!
Do you also want to show your creation? Send us your pictures!
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.
Our ClassicPower PCB looks nice with these NOS Roedenstein capacitors. The PCB is available in black and white in our shop.
Today I found a pair of NOS[ref]new old stock – components that were produced sometime in the past, but were not used yet[/ref] ROE EYF 06 electrolytic capacitors. After measuring them I was lucky to see, that they still have full capacity (4800uF and 4700uF). And wow – these things look great! The gold color will look great on a black PCB. I’m thinking to design a new PCB similar to the UniSieb circuit, but with these capacitors (only 6 of them will fit on a 8x10cm board, because they are quite large with 30mm diameter).
Any other ideas how to use them?
This 4 channel volume control is based on the Burr-Brown PGA 4311. The input is buffered by a quad opamp. The module needs a +/-5V power supply. Digital input is fully isolated by optocouplers.
The circuit can be controlled from any microcontroller. Examples for Arduino and Raspberry Pi are available.
The module size is 5x5cm, expect more modules in this size in the future.

This project was started to transport the sound from my turntable to the loudspeakers without visible cables. Our flat already had ethernet in all necessary places, therefore the idea was to transport audio over ethernet.
I didn’t want to use large and expensive hardware for this experiment. Therefore the Raspberry Pi looked like the ideal hardware. It runs Linux and has integrated sound, network and USB. Unfortunately the sound hardware is unusable, because it does not feature an analog input. Therefore an additional sound card is needed. My choice was the Behringer UControl 202. It used the Texas Instruments PCM2902 chips that is well known, well-supported and good-sounding.
Stay tuned for more informations on this project.
The Beogram 1200 is not the most advanced record player – but it may be the most stylish. Jacob Jensen designed it in 1969. It is part of the design collection of the Museum of Modern Art.
