Does anyone even have a functional babyjet/sierra still that didn't need to be sent back for repair?
I have two hashfast babyjets that have a ghash.io one day hash average of just slightly above 400GH/sec. Initially I had a windows server connected via USBs to the miners running cgminer 3.11, but now I just have the raspi's controlling the miners and I have a netboot power device that auto-pings the minepeons ---automagically power cycles whichever minepeons doesn't respond to pings.
Other than a HUGE FORM FACTOR for the hash output involved (Antminer S2s are better), my Baby Jets now are finally doing just great...
