I already sold off my S1s and upgraded with S3s directly, so I won't be purchasing the upgrade kits. I'm glad I did, 9/20 is a long ways off. One thing I'd like to add here is that the upgrade kit really doesn't make sense. Here's why: Your S1 is already getting you 180GH/s (or 200GH/s if you've over clocked it). The upgrade kit effectively turns your S1 into an S3. You gain 273GH/s - 304GH/s (base clocks to both over clocked). So, is ~275GH/s worth 0.46 BTC (by the way, the MOQ on the upgrade kits is 2, so you're looking at 0.92 BTC). It is much more efficient per watt too....... That goes without saying... the S1 is 2W per GH/s, the S3 (and the upgraded S1) are 0.78W per GH/s. I think my main point was that with a ship date of 9/20, neither the S1 or the S3 make a lot of sense. I got in with the early batches (1, 4, 5), so by the time the S3+ comes out, my S3s will have been mining for a couple months. Yeah....the early adopters won out, and the later batches have too small of a discount to win. |

None of Bitmain product offerings make sense considering the difficulty will be up 50% (1.25x1.25?) by Sept 20 ship date. The S3 upgrade is basically saving you a little money by reusing the shell from the S1. It would make more sense to sell the S1 and just buy a S3+ but even that is way overpriced for Sept 20 ship date.
Bitmain doing preorders Oh God
September 20 is so long away and difficulty is going up exponentially....I agree. Not worth it |

I was looking at the antminer S3 page, at it says it is 355 watts with a 225 mhz frequency.....Is it possible that that S3 just has a lot of undervolted S1 chips? Anyone with a S3 can comment on this? Or is this a nm change?

I think you're one of the many miners that quit. That's why the ASIC devices are getting cheaper and cheaper. This has happend for GPU's too, you can buy some used GPU's for great prices nowadays.
However, it might still be profitable in the long run to mine now. You might not make profit now, but what if the Bitcoin is worth, for example, $5000 next year? It might have been profitable then to keep on mining now.
If you're assuming that BTC would go up against fiat in he future wouldn't it behoove you to do everything to earn as much BTC as possible. If mining is a loosing proposition compared to buying the coin, why mine in the first place. People need to do basic math before making mistakes like this. My Antminer S1, soon to be S3 has squeaked out a profit, but mining is tough. GPUs aren't making nearly as much as they used to. |

Are you buying these solar panels wholesale or retail cause to me right new solar energy is costly and take like 10 years to make back your savings which they should be cut down to 5 years would be nice.
I was looking at more like 5 years, and if you make your own panels 3. I'm not sure this makes sense but it doesn't break any laws in nj.....so that's why I think powering the miners directly might be interesting. |

Solar Panels Powering Bitmaintech Antminer S1 or S3
Parts:
Panels
Charge Controller (12v or 24v, at least 30a 12v, or 15a 24v for one antminer S1/S3)
Lead Acid Batteries
Antminer S1 or S3, running at 12v
If in 24v setup, then connect a 24v to 12v step down
Cables and Connectors
PCI connector
Optional if you want wall power over the nighttime:
Power Supply
dpdt Relay
1. Panels
Place Panels outside in sunny area, perferrably south facing, route cables to controller
2. Charge Controller
Take the wires from the Solar Panels and place them into the connectors and crimp them. Connect the solar panel's connectors to the solar panel ports on the charge controller. Next, connect the batteries to the battery ports on the charge controller. WARNING: Make sure if the panels are 12v, then the batteries are 12v, and if the panels are 24v, then either make sure the 12v batteries are connected to make 24v, or use a 24v lead acid battery.
3. Antminer Connection
12v: use two male pci connectors and connect the wire sides to the output of the charge controller and then connect the male cables into the antminer s1 or s3.
24v: connect the output of the charge controller to the 12v step down converter, then connect the converter to the male connector, and then plug it into the antminer.
Nighttime Power:
If you want nighttime power, then connect the output of the charge controller(after converted to 12v with converter) and the output of the computer power supply into the NO and NC of the DPDT relay, and the corresponding terminals. Then connect the output of the relay to the antminer with the male pci cable.
Ask questions or share knowledge below, I haven't tested this myself but I'm pretty sure this'll work.

When I get time I'll make a full blown guide for solar panels because there seems to be enough interest in it....

All except a solution to connect the antminer to the setup.
What is the setup parts? I'm assuming a 24v panel with 24v (hopefully 15a charge controller)? 24v lead acid batteries, and a 24v relay? |

I'm too confused and stuck here for a solution.
Oh, OK. What parts were available again? |

Now I decided to connect the dc devices directly from DC out.
My battery setup is 24V and Solar MPPT charge controller out put is 24V DC.
Any one know the Antminer S3 input voltage tolerance?
I will be converting this 24V to 12V via a convertor which can provide and an output power of 400W.
Sorry, I've been busy but that's cool allcoinminer. Thats exactly what he told me on how to do it, use a charge controller from the panels to a battery and then takes the battery voltage into the antminer through the charge controller. Don't rely on me but I believe the antminers have a higher tolerances because the actual chips run at a lower voltage through their mofsets and don't directly use the 12v. The mofsets probably have a higher tolerance. My charge controller does not have a DC out other than to battery. Also, these DC output in Charge controller are normally of 10A where as Ants need 35A. So I'm confused? How are you doing it right now? If the antminers are connected directly to the batteries, you can destroy the battery by totally discharging the batteries. Also, the charging of the batteries must be slower than the output it can handle with the charge controller. The charge controller would bypass the battery if it had enough 12v and directly power the antminer. |

Thanks, just being cautious. Will buy asap!  |

Anyone have any experience with cryfter? Want to buy Minecraft but there has been so many scams out there..... Just being cautious  |

This looks really nice. This'll work really well for when us miners have to pay taxes on our daily income. Thanks!

OK cool. The last donation in 2011 was only $50......so I guess bitcointalk is rich now  |
|
|
|
I was looking at the donation page and it says people donated 50 and 10 bitcoins?  isn't that like 10,000 to 50,000 dollars depending on the price of bitcoin? |
