All of this takes place during the same difficulty on the same pool (BTCguild) with the same equipment, except for one thing which I will get too. So I recently bought a couple Block Eruptors and I got loads more on the way. At first I was running them on my PC using CGminer. The 2 miners would pull an average of 700mh. Now I have a raspberry pi rig set up and they are pulling a little less than what they were before. Not much of a drop just about 680mh now or so.

 My question is that since I switched from a PC to the RPi my 24hour income has plummeted. The only real change I've noticed on the pools end is that there was steady increase of 10k gh from 110k to 120k. Anyhow my 24hr rate went from 0.01 btc daily to 0.004. I'm using the same methods of mining PPLNS and my accepted share rate has been 99%. Like I said I'm new and I don't understand what has caused this.

Luck of the pool will affect the pools overall earning.  If the pool is earning less then your 'split' of the pool's reward will be less too.

Read today's post of the "Weekly Pool and Network Statistics" thread about BTCGuilds luck.  Maybe it's pertinent?

You may be comparing 24-hour earnings during a period of high luck (which we've had many of in the last month) against with a period of low luck PLUS the massive difficulty increase earlier this week?

2 block erupters right now should be averaging approximately 0.0067 BTC/day at neutral luck, assuming 24/7 mining.  Pool luck has been slightly above neutral the last week, so that would be what you should see on 24 hour earnings (24h earnings is an approximation, so it could be showing slightly above/below your actual 24h earnings).


A few possibilities:
1)  How are you running the Erupters on the pi?  Hopefully an external hub with adequate power (not the same one being used to power the pi itself).
2)  Are you running them at a high difficulty?  Running at a higher difficulty will increase your 24 hour variance when only mining with 2 block erupters.
3)  Not running 24/7, or internet connectivity issues?

It was most likely the difficulty increase on 13/08. My 24h earnings also dropped a lot since I was only hashing at 1.6GH/s on BTC Guild.
