Lot of Value, Little Money. Buffalo II DAC PS Output Cap Mod. Buffalo II DAC PS Output Cap Mod. October 5, 2012. One possible place to mod is the output capacitor for the on-board power supplies for digital section of the chip. The regulators are based on the LT1763 low noise LDOs with a specified noise figure of 20 uV RMS. According to some reported measurements the noise figure can be further reduced by increasing the output capacitor. The results have been reported in diyaudio:. The current configurat...

Lot of Value, Little Money. On the other hand, I think the introduction of the Buffalo II DAC represented a quantum leap to everything TwistedPear Audio had produced up to that moment. In a way The Buffalo II DAC represented the Aha! Product for Russ and Brian. Not only was the Buffalo II DAC solidly engineered, but its built quality was top notch surpassing even commercial offerings, and it was also popularly priced. Finally, there it was: a state-of-the-art DAC available for the do-it-yourselfer. The f...

Lot of Value, Little Money. This blog has been sort of a notebook for me to write down my own learning with Arduino and the TPA boards. Therefore the information presented assumes that the reader’ is learning at a pace equal to mine. April 2013, the TPA controller board in not yet available, so this is the only “ready-to-run” option). HIFIDUINO is about building a controller that can talk to those audio chips. So far I’ve interfaced to the OPUS DAC with the WM8741 and the Buffalo II boards....Any officia...

Here is my board (S/N 000003) and even personally signed by Soren🙂. I will document my build in this post. Just finished building a /- 12V power supply and had it powered-on an entire day in order to ensure that nothing was wrong with it. Most of the components are from my “pile of electronics”: some now, some recycled. Two transformers (AC 15V). If bu...

Lot of Value, Little Money. Based on more accurate information on the protocol codes, I’ve update the information in this page. I’ve been using the Apple Aluminum Remote for my Arduino based HiFi projects. In my opinion, this is the perfect remote control for such projects because of its simplicity and good design, in addition to be reasonably priced at about US$20. Remote codes description [ link. NEC-based remote protocol [link. Control for Arduino/Buffalo II DAC [link. Perfect dimensions and weight.
