HiFiDUINO in Korea

A reader in Korea sent me these pictures of his project. He is using the same Arduino to  control both the Buffalo II Dac and the SDTrans transport. Even after connecting the LDC, remote, rotary encoder and I2C connection to Buffalo II, there are still 5 free pins. 4 of the pins are used to control SDTrans by connecting to the wired remote header and mimicking the press of a button: pin HIGH, delay, pin LOW.

With the single Apple remote control (and only the 7 available buttons) he is able to:

• Control the digital volume of the Buffalo II Dac
• Select any track stored in the SD Card, pause/play and jump to next/previous track in the SDTrans
• Switch I2S inputs through a relay

Very nice implementation of the Apple remote

The Arduino is a diy design as shown in the bottom picture. The Buffalo II Dac can be seen in the upper right corner for the first photo.
