Since I get regular questions about my last Bitcoin post,I thought it might be helpful to post a brief update.

BFL SC Singles!

As you can see,I did finally receive my two BFL SC Singles from Butterfly Labs.I've had them now for about 6 weeks (they arrived around June 25th),and everything is running smoothly.Each SC Single runs at about 59-60 GH/s and each uses about 280 watts under load.Also,my Jalapeno is now running at almost 8 GH/s thanks to a friend from work helping me update it to newer firmware.And yes,I have a couple ASICMiner USB Eruptors,just for fun.

You probably noticed that I have removed the cases from all of the BFL miners.You can't tell from the photos,but I also flipped the fans on top of each miner over so that they blow down instead of up (which is better cooling). The SC Singles also used to have fans on each end blowing sideways.I removed those and instead just use some larger table fans (running on low speed) to keep air moving in the area.

The main benefit in removing the cases for the miners is that they are much quieter without the metal grates that were previously up against the fans.With the normal cases on,the SC Singles were making an very annoying and reasonably loud whining noise that was audible even through the walls and the ceiling of the unfinished basement room this stuff is in (which was not cool with my wife).With the cases removed,this entire setup is reasonably quiet.Much quieter than my old GPU mining operation,and cooler as well.

In the 6 weeks I have had the SC Singles,they have earned what I paid for them a year ago (in USD) several times over,so I am quite happy.

Dashboard

I also updated my custom bitcoin mining dashboard so that I could keep a close eye on these since a mining downtime means non-trivial loss of BTC with these guys. A couple notes about what you see there:
