[arm-allstar] hum on my allstar nodes

[Jed Barton]

Hey guys,

So i'm sure i'm not the only 1 with this problem. I've got all my
allstar pies plugged in.  They each have their own power supply. It's
the typical wall wart.  They all produce a nice little hum that's just
annoying.
I'm sure a lot of you guys have delt with this.  You hear it on the
node transmitter such as the Shari.  Any ideas for getting rid of it,
or reducing it?

Cheers,

Jed
