The 3D files for the modified Pibow case that can accommodate a Raspberry Pi and HiFiBerry DAC (the RCA version). It can be downloaded from Thingiverse.
Print the layers by yourself our let it produce by a 3D printing service. You might also remix it for any use you like.
This is a preview of the modded Pimoroni case with additional layers for the HiFiBerry DAC. We will release the STL files soon.
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.
One of the HiFiBerry DAC users shows a nice example how to integrate the DAC into a standard case. He removed the onboard video connector and use the space for a phone connector. Really nice work!

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?
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.
The German company Dual had a long history of idler-wheel record players. Many manufacturers introduced belt drive record players in the mid of the last century, but some companies still produced idler-wheel drives. Dual was the last big company building idler-wheel turntables. Dual produced the 1229 model during the years 1972 – 1974. It was mostly based on the Dual 1219.
