Some daisy chain to go with you poly chains?

So if ultimately I have a shruti and two shruthis It would be nice to find a way to power all three of those bad boys but not use 3 wall warts. Would daisy chaining the power be possible somehow or are multiple warts unavoidable?

I haven’t measured what the Shrut(h)i draw, but it’s in the 150-200mA range (mostly for the screen), so with a 500 or 600mA supply you could power 3.

perfect!
