DIY: amb/linuxworks Delta-1 relay volume control
a stacked (balanced) set of modules and also a non-stacked relay board+controller.
the arduino (LCDuino1) is behind the amber LCD in the background. it runs VOLUmaster code that I wrote.
volume control is via an r-2r relay resistor array that is i2c controlled by the arduino.
a single relay board can support up to 8 bits (8 relays) and its typical to find half-db steps on 8bit boards. 7bit boards can cover -127db to 0db in single db steps using 1 less relay.

I posted this photo to head-fi but the angry mod that hates me auto-deleted it moments afterwards. I can't imagine why but it seems that headfi does not like DIY projects or does not like them from certain people... BOO on head-fi for such censorship! let me post photos of my projects. stop the arbitrary/selective censorship!
