Hey would you mind sharing 3D model of 6" one... I got 3D model of 4", and my temperatures are pretty high at the moment around 85ish more-less. I forget how to work in Solidworks. In last few years i worked in Tekla Structures, but that program cant export STL  No problem, let me ask my friend. |

Hi Rich, I'd like to order an Onda B250 frame. Basically the exact same as what Phil has as I will be using the same 1070ti hybrid cards and a single PSU. Please let me know the total and I'll pay up. Thanks!

I just want my miner very quite at the end of the day and cant have 25 feet of tube everywhere.
You should look at GPU mining, ASIC miners are loud and hot, there's not much you can do about it with out causing yourself problems... |

I was in the same situation , maybe you can keep looking and can find somewhere that has a better ventilation set up
I managed to find a place that has windows and all I need to do is put huge exhaust and intake fans at the windows
The single garage door set up is pretty hard to cool well unless you start punching holes in the side wall or ceiling
Thank you, that's exactly what I've decided to do. I am going to wait to find the right building to lease, or just end up buying so I can do what I want to. |

I see lots of folks here asking about adding ducting to their miners. And while you should really house your miners in a dedicated space with adequate airflow, sometimes we have to make do. So I thought I'd pass on a few things I learned. 1st be careful of the 3-D printed stuff on eBay, some are OK, but others are overpriced and not very well thought out. Not to mention printed out at very coarse resolutions. Personally I feel that to provide the least amount of restriction you should use a 6" adapter and 6" ducting. I tried a 4" eBay duct adapter on my S9 and the temps skyrocketed *without* any ducting. Then I tried a 5" and it was better, but I could tell temps were still a few degrees better. Finally I had a buddy make a nice 6" adapter, this had no effect on the miner's temps. Here's a view of 3 miners with the 3 different sizes in ascending order from left to right.  Here's a couple of closer pics of the 6" adapter my friend made and what I plan to use on all my miners.   Here's a mock up of the 6" ducting (I need to clean everything up  ), the other one in the background is 5" ducting. I wanted to make sure the 6" worked out before my friend made one for each miner. Also the two blank holes are for my 2 M3s that'll be here mid-late Feb.  Here's a couple of pics of the backing board with the 6" starter ring holes, it is going in a hole cut for an old window A/C unit. I cut this out on a CNC router.   EDIT: My friend will be adding the duct adapter to Thingverse, so just search for Antminer. It should be there soon. Here's my parts list: 6" semi-rigid duct http://amzn.to/2DyBDW5 semi-rigid is kind of a PITA to work with, but I feel it has a smoother tract with less airflow interference. 6" Starter ring https://www.homedepot.com/p/6-in-Starting-Collar-Take-Off-Snap-Together-SCF6/100396966Duct sealant, used this to seal the starter rings to the plywood http://amzn.to/2DyvbhT |

I just checked their site via Google Chrome on Windows 10 and it seems fine to me. The malware alert is probably a false alarm from AdGuard and unless someone else can prove otherwise, it should be safe to use.
Just passing on what popped up. What AV do you use? Just Windows Defender? It could very well be a false positive, I hope so!  |

Thank you for your answer !
But my question was more related to the payout.
I don't understand where is the link between the antminer mining and a BTC wallet where the payout should go.
I will choose a pool, but then what ?
You pool of choice will have very clear directions. Maybe you should stop and before going any further do some research. |

Anyone else getting malware alerts when trying to access the Pangolinminer site?
OK, the pic above just rendered for me.

Hello Bitmain
I am REPEATEDLY telling you since i made payment that ADDRESS is not VALID and just a PLACEHOLDER address to UPDATE my CORRECT address, despite of my repeated requests you have SHIPPED the unit to a address which DOES NOT EXIST
Now what will happen? I never expected this from you Bitmain, on SAME email you confirmed payment but did not even acknowledged updating my email, this is INSANE and NOT EXPECTED From Bitmain professional company.
ONCE again, you are requested to IMMEDIATELY contact DHL and get address updated For my Order ID: 0012018011709001:-
For my Order ID: 0012018011709001 I repeatedly requested you through the same email when i make payment where you responded acknowledging payment but never responded to my address update request, then i submitted tickets, sent you tweets but you are too busy shifting from China to Canada that you don't care about customers.
Now due to this poor support of yours my miner will land no where in UAE because address is a place holder and its even writtent in it
Can someone please get Bitmain on the line please or any phone number of them where i can talk them.
Thanks
Um might I recommend https://shop.bitmain.com/support.htm?m=technicalSupport rather than flailing about here? Also, and I am sure you have your reasons, but why in the world would you put a "placeholder" adress in your order? 1. I did that same time to their support and also the payment email where they replied me on balance payment and 'ignored' the address update part. 2. The place holder address was placed because the time was so less and i had no time to update address, you know batch was sold out in few minutes. I see, that link I posted has their phone number. Perhaps you should call. |

Yes I pressed both of the red breaker buttons (although, they didn't "feel" like they did much). I looked up the manual to the PDU and confirmed, one PSU was plugged into one end, the other in the other end (both in different banks).
Gotcha, I don't have experience with that particular PDU, but others that I've used give you a tactile feel when you reset the breaker. Just like the one in your panel you might have to fully depress it down and then reset it. |

I pretty much know the answer to that, no, they shouldn't  . That's why I'm baffled. Trying to determine if I have faulty power calculations or just got a bad PSU. My setup: 240/250v 30A Dryer Recepticle (NEMA 14-30R) NEMA 14-30R to L6-30R for my .. PDU30BVHVT20F (Cyberpower PDU 30A) I have two Avalon 741's, two 1200W PSUs from amitylabs ( https://www.ebay.com/itm/Power-Supply-for-Antminer-L3-110V-or-Antminer-D3-L3-A741-220V/182723026931?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649). My calculations 2 miners = 1200w x 2 = 2400w 2400w / 240v = 10A each 10A + 10A = 20 AMP total. On a 30AMP plug thats roughly 67% load all the time (in safe range) I ran one miner for about 8 hours just to see how it worked before hooking the second one up. Hooked the second one up to the opposite bank on the Cyberpower PDU, and after 1-2 minutes I heard POP - outside breakers didn't flip (I think the PDU breaker did). Now the PSU is bad (no lights come on on the PSU - ever). So are my power calculations off, or did I just get a pad PSU? Amitylabs has an awesome reputation and amazing support, so I don't doubt they will rectify the situation. Just want to make sure I'm not about to burn my house down. Note: I confirmed that the Avalon 741 did not die, just the PSU. I'm currently running the 741 on the first PSU that works. You reset the breaker on the PDU right? And you definitely confirmed that you have each miner on a separate PDU breaker? |

Just spoke with Sidonia on a B250, quoted $130.00 + $58.00 shipping + PayPal looks to be ~ $200.00. Reading this entire thread the Onda seems like a good deal even at $200.00 right? I do plan on using an open air case and smOS. Not sure what cards yet as they seem really hard to get. Before Christmas I was able to snag some single fan 1060 6GBs for $279.00, but nothing near that now.

Generally you do not see the air being ducted in because the key to keeping the miners cool is removing their waste heat so they do not pull it back in. If you do use those duct adapters I would recommend a 6" for an S9. I tried a 4 and 5 and those both raised the miner temps, the 4 especially. |

Like I said before, if your miner is paid off then sure. If that $100/month (and decreasing every month) goes towards paying off that miner (at $3000), it's definitely next to nothing in my view. In any case $100/month can only be seen as a hobby in my view. I **did** have to pay off my miner. That's what I am trying to get you to see. I bought it, it had a cost, I must recover that cost to be profitable. If you'd look at my posted pic you can see clearly how much it's earning. And again that's why I am questioning your math, that miner, as old as it is, should not be making anything at all. But it is, now you're qualifying what's profit and what is not. That's not math, that's subjective I know, I believe you. You did, indeed have to pay it off, BUT, when difficulty/hashrate was much lower, that miner would have been making much more than it does today no? Also, your initial investment was much lower as well. And there is one thing you can be (almost) sure of, it will make less and less as time progresses. And that is what I am trying to show in this spreadsheet for the S9 specifically, bought today at $3000, But you could adjust the numbers to an S7, bought today at ~$700 and see what you get. And to answer your question from before, the reason miners can(will) go from being profitable to non-profitable in such a short amount of time is because the difficulty is increasing at ever increasing rates. If they were increasing in a linear manner, you would be able to put a fixed "profitability" time on a miner, but the curve is not linear, it's exponential. Yes sir, I understand and agree with everything you're saying. However my disagreement is simply with the accelerated rate to 0 you propose. True enough that difficulty is not linear, however it is not as predictable as you lay out either. And that in my noob, uneducated opinion, is the flaw in the math. |

They just tweeted that they are releasing a blake2b miner as well, with supposedly better stats than the A3. That's awfully coincidental don't you think? I mean why go after one coin? I can see an established company doing it, but now there's two vaporware miners with one drawing the ire of a particular coin.

Not sure if this is what you are talking about, but something like blockchain.info has? but for all coins? https://blockchain.info/apiI dont know where the calculator sites get their info, but lots of times, it seems outdated. I would guess running own node would be only way to get realtime realtime without going through service like blockchain.info Yeah its a major pain in the ass, I'm needing it for all SHA-256 coins that are currently being mined. I resorted to writing a wrapper to pull statistics from bitinfocharts using Beautiful Soup and then parsing the html for the data. It works but I really did not want to do that as it adds to my coding load lol. Have you looked at coinwarz and whattomine's APIs? Easy enough to pull down JSON and play with the data. |

So I don't have a degree in MS Excel, but I cannot agree with this prediction. Before I spent money on new miners I picked up a used S7 off Ebay, this was pre-psychotic pricing ($630.00+ $37.00 shipping). Before doing so I looked at the predicted earnings and compared that to the price of the miner. I set my target buy price to ROI at roughly the same time a new S9 would. It took me a bit, but I found a solid seller. So yes, if you spend too much on **ANY** miner (or business equipment for that matter) it will not be profitable. But if your spreadsheet and theory were accurate and as predictable as you make it seem that old ass miner should not be making anything! Yet is is happily hashing and has almost paid for itself.  It has already paid itself off, (almost) That is very different. Any money it makes after that is profit as long as it is more than your power cost. This scenario is specifically for an S9 starting to mine in Jan 18. Darn close, I'd have to add everything up. Initially I was having so much fun I didn't do much record keeping. Anyway why would the spreadsheet only be for an S9? I mean difficulty and hashrate don't care right? It's simply how much I paid for the machine vs. how much it can produce? I do agree that earnings can and will be affected by difficulty, that is a given. I am just trying to understand how a machine can go non-profitable in such a short amount of time. Because again if that's true then S7's or any old miner for that matter should not be profitable either. |
