Can anyone comment on using Raspberry Pi vs. the Controller?
Can the RasPi vary the Mhz up to 900?
Does the RasPi get the same hashing rate for the same speed?
Can it run the miners without rebooting (or rebooting only one miner when the miner disconnects)?
Any other advantages or disadvantage of the RasPi vs the controller?
I've got 10 running off my RasPi:
1. Yes, you can vary it using the --freq=900 flag for minerd.
2. Yes, in fact I'm seeing a slightly higher rate, but that could just be because of the improved stability.
3. Yes, running rock solid for 3 days straight now with no reboots, freezes, etc.
I won't switch back to the controller unless they do something amazing with that firmware.
I like the concept, but i'm curious how well it can scale with a more sizable amount of miners. Would a RasPi be able to support dozens of units? I've heard the controllers that ship with the units can technically support up to 20 units, but they are underpowered and the hashing increase tapers off as you add miners (sorry I don't have the source for that report).
