How difficulty adjustment works: Every 2016 blocks, the Network adjusts the current difficulty to estimated difficulty in an attempt to keep the block generation time at 10 minutes or 600 seconds. Thus the Network re-targets the difficulty at a total difficulty time of: 2016 blocks * 10 minutes per block = 20160 minutes / 60 minutes = 336 hours / 24 hours = 14 days. When the Network hashrate is increasing; a difficulty ( 2016 blocks ) should take less than 14 days. How much less can be estimated by comparing the % Network hashrate growth + what the Network hashrate was at the beginning of the difficulty ( 2016 blocks ) against what the Network hashrate was at the beginning of the difficulty ( 2016 blocks ). This is only an estimate because you cannot account for "luck"; but you can calculate reasonably well using explicitly delimited stochastic ranges. The easy way to think about this is to look at this graph and see how close to 0 the current data points are on its y axis. If the blue line is above 0 the difficulty ( 2016 ) blocks should take less than 14 days; if it is below it should take more. http://bitcoin.sipa.be/growth-10k.png |

These are Great! Will probably order some depending on pricing. Any reason why you didn't opt for an internal hub and one RJ-45 pass thru?
Space and power requirements mostly. Any particular hub you thinking of? |

The hash case with the Delta fans has the miners running in the mid 30's temp wise. The stock Bitmain fans are running in the upper 40's, a couple units are around 60, so the Delta fans are certainly much better. However, they are MUCH louder. Thankfully this is in a datacenter environment so it fits right in and you expect the noise.
The PSU case with all 4 power supplies is running very cool to the touch. There seems to be no issue with the 4th PSU in the back suffering from all the rest of the hot air from the first 3 moving through it. Now these PSU's are half-loaded, only 3 miners per PSU at the moment, so we'll see when I can get them set with a full compliment of 6 miners per PSU whether heat becomes an issue. But with the volume of air that's being pushed through I still doubt it'll be an issue.

50-55 lbs. each ant is roughly 5-6 lbs and the case is probably 10-15 |

It's a nice thought, but honestly, there's really nowhere to fit one of these inside the case. Plus then you also have to worry about the brick transformer and/or customizing a 12v plug for it from somewhere else. Really the only way this is usefully done is to have the cabling done the way it is. There's enough room on the outside of the case if you wanted to surface mount one and go that route, but trying to find enough room inside, especially without it impeding airflow (most of the challenge), is quite tough. |

50-55 lbs. each ant is roughly 5-6 lbs and the case is probably 10-15 You're probably close but it's a little less than that. Remember there's really only the hashboards and control board - none of the brackets on the ends go in, there's half the fans total, and there's no outer metal shell anymore. Each hashboard case fits 6 Ants. The case itself is extremely light, at least this prototype one, because it's only .30 thickness. If these make it to production it'll be double that so there'll be some structural rigidity, and then I'd agree the case would be 10-15 on its own. Seat of the pants feel from actually carrying it around and getting it situated in the rack, I'd say it's probably about 45 lbs for the hashboard case fully populated, and about 20-25 lbs for the PSU case. If I get a chance to weigh it on a scale when I move it to another rack in a week or so I will. |

Very nice. I had picked up a few empty 4u cases to try to modify them to hold ant s1's, but i have to say - this looks so much nicer than what I was trying to rig together.
The PSU case is awesome - i was trying to figure out how to manage the psu's on the rack. One really cool improvement would be if you could get an extension cable that went from the output of the power supply to the case where the ants where. then mount the break out board in that case. then the PCI-e cable mess would be enclosed in the ant miner case.

Thank you! We are actually working on something like this as we speak. |
