I'm running two 30 g bfl miners and 10 block erupters with a Pi --- and 20 erupters on another Pi i'm using d link hub for most erupters and an orion 10 hub----- is working great but every 2 days or so one of the pi miners shuts down any suggestions
Check on your power supply, usually thats the problem...
this . what are you using to power the little singles? if it is the stock power supplies they are not that good. If you are in the usa pm me I have a ton of used but good pus's. if you want a new psu I have a lot of links for low cost psu's
