[Skimmertalk] Alternate 5V power supply for Red Pitaya?

[N4ZR]

Oh well... I didn't notice which list it came off.  Anyhow, I am running 
my RP off a generic 2-amp switcher and it seems to be happy.  There are 
some very beefy 5 volt regulated linear supplies out there, like the Bel 
HB5-3/OVP-AG, but they cost about $65 new in the US.  I suspect the 
supply voltage in Fiji is probably 200-220 volts, and 50 Hz.
