what I am planning, so far:
just completed (well, almost complete, as of right now) a beta22 build that is a little bit different from the rest:
it uses an arduino inside (LCDuino without lcd), has a delta-1 relay attenuator, IR remote and motor pot - but also uses a nixie display for dB readout. kind of fun and somewhat uncommon, with all the LCD builds going on these days.
I also updated my build of the gamma2 dac, with a built-in spdif 'meter'...
