Bitcoin / Mining support / Re: New mining room - need input for intake - exhaust setup
|
on: June 14, 2015, 10:11:42 PM

Are you prepared to open that window all day and night? If that is ok, mount a wooden board on the window-sill and cut holes on the board to mount 2 fans, one moving air in and the other moving air out. If you want the window closed for security, you will have to cut holes and mount fans on the glass.
JB, thanks very much for the input. Yes the window can remain open for months. Security is not an issue. Unfortunately it is high traffic with cars going by all the time, but not much foot traffic at all. I guess that is good and bad. Regardless your idea may be the only thing I can do, which I thought about but even with "heat rising" and of course I would put the exhaust up top, I am concerned I will be pulling that exhaust right back in. Although, I should be able to control that with the fans. IF I put the much larger one on the exhaust side it should push the exhaust further, faster. The miners are currently all sitting on a large wire racks across the room. There are stacks, but I should consider going vertical to make this work the best I think. I lose too much space by doing a vertical arrangement. though, no stacking :/ I may just have to try it. I ran the CFM numbers, but I do not know the heat to cool including CFM and static numbers, and my "duct" or air routing methods are a hodgepodge of things, but it works without any hard 90 degree turns. There is an attic space, but I am concerned about how much heat I put up there and how it may affect the cooling in other parts of the facility. I was just up there last night and didn't see any vents to the outside in that area of the space or I would have disconnected the AC vent tot hat room and ran an exhaust to the outside. If I dump straight to the attic it may cause a huge heat buildup there. Again, thank you for the input. I may not have any better choice. Much appreciated! |

Bitcoin / Mining support / New mining room - need input for intake - exhaust setup
|
on: June 14, 2015, 09:17:03 PM

The summer months are brutal for me, and I thought I had a great space setup until I saw the windows to this "room".
There is only one large window which slides open. Half the window cannot be used.
So, I either have an intake, or exhaust, or split it into both. Fans I have covered, big ones, and I can make my own duct, or equivalent air routing methods which are proven. The source is the issue.
I have not yet thought of a cost effective, non-permanent damaging way to introduce another source for either an intake or exhaust.
The window I do have is a decent size, which I can measure if it matters, but say it is 30" X 30".
I don't want to get caught up in providing the specifications of my mini-farm, so I'm not asking for help to calculate CFM, etc, but I am sincerely asking for any advice on how to best cool a room with one window and no other way to provide another entrance / exit.
Say this window is the only way to move air in or out of the room and it is extremely preferable not to have anything hanging outside the window.
I am trying to cause the least amount of damage because I plan to sell this "room" in about a year, so would like to avoid ripping out the other part of the window, or cutting a hole through the brick on the outside.
I also do not want to draw attention to this as it is not noticeable unless I put something outside the window, but if there were to be a large 90 degree elbow pointing down for a cool air intake it becomes noticeable and there is too much car traffic for that.
Fortunately noise is not a concern.
Where I moved the miners from I had my exhaust much higher than the intake which was close to the ground. In this new space the power is cheaper, the room much larger, and I have the infrastructure to add a decent amount of miners. The overhead is available to double my current setup, but until I have this issue reasoned out I cannot run everything I currently own as I am pushing an average 65 on the miners now. The few S5s in the mix run the hottest, the S4s not far behind, and I have my SP20s clocked way back and still usually have at least one side pushing uncomfortably hot. The SP20s and S3+ units run the coolest, but still hotter than I think is good.
Any suggestions outside of going vertical because that still does not give me a good intake / exhaust scenario.
Thanks for any input!

I am posting a response in this thread to state what I purchased.
I have paid for three BITMAIN S5 Asic Miners which OgNasty states will ship on Wednesday to my fe.
I will leave the price out of this post and let Og add as he sees fit.

A few questions others may like to know as well.
How long have these been mining?
Have they been ran at stock or OC? If OC what speeds?
Why cut the fan wires? You used your own fans?
Have they been run in a dust free environment?
Do any run an average speed under S5 quoted average?
If you OC each unit do you have any which are clear leaders?
If not too personal, why do you wish to sell?
Thanks OGN, you are a good vibe in the community.

The mining difficulty is what gets us brother. I feel you, it would be great, but I doubt we get 13 months out of the S5s. The next-gen gear is either already being mined with by manufacturers or it is almost ready. The mining difficulty is going to go high, very high, and the people who gamble on next gen to make money, well they will gamble. Bitcoin mining is not for a profit at this point. It is for people like me and others who want to help keep something going, enjoy this crazy sometimes spastic community, and see it as a hobby. Building your dream car, or overclocking PCs, or etc type of hobby where you spend. Some people trade their power bill for BTC through mining. In my opinion, unless you have about 200 - 500k, make a deal with a reputable MFG company like Spondoolies, and move to the right place for real cheap power do not expect a profit. Do not mine for a profit only buying a few units. Don't get me wrong plenty of people told me the same thing and hear I have with more than many and I guess less than anyone making money, but the only people making money from mining have either done what I said (which is still a huge gamble) or, they have free power. If you want to be in bitcoin and think the price is going to go to the moon, buy coin. Make sure you can trust people you deal with. Watch who and where you buy from depending on your needs and keep in mind Bitcoin is not anonymous. That is a myth. You could always try renting some hash, see the link in my sig. I like doing business with these guys. I think they are fair, and do their best to be straight up with customers. I sometimes want to gamble, very rare but I call it gambling bc it all is and I rent and throw it at Kano or CKs pools. I may even rent to grab some of an ALT that seems to have good technology, but still, I do not do it to make money. I go into it knowing I've lost that money and anything I make is awesome! I wish it wasn't this way, and maybe one day things will be different, but I have to think the true "glory days" of mining are past us. Even if you mined strictly to have the coin, you will have more coin by simply buying the coin. Today's prices are a perfect entry point to bitcoin. I believe it is going up to 270, 300, 320, etc and will find another floor about 90 dollars higher than where we are now, and another year or so the same. I would love for everyone to run a full node and keep no less than 3 or 4 miners running forever, but I am not a fool, at least not in that wishing department  By the way, nicehash is the UK service and westhash the US one. Same company as far as I know. If you see posts from Kano, CK is a mod, and PhillipMA you can trust them. Don't tell anyone your personal information and never give someone coin. There is a guy named OGnasty who has an amazing reputation for handling escrow. You give him money, the other person sends you product, once you are happy with product OG releases the money. Do not do it any other way because there are sharks here man, people who make there living stealing from honest folks. No matter how street smart you may be, there is trash around who can take it to another level. Be smart and don't tell anyone exactly what you have, especially financial information, where you live, etc. Good Luck! *Significant Edit* Sidehack who replied to you is also someone who shoots straight. He sells good products, and is a good guy even when grumpy with my nubish questions If I was making a list of good people here it would be a decent size one, so don't think everyone is a scammer, but there are enough to where you should always be safe. How fast does the mining difficulty increase? i ask this because i was looking at this as more than one possible idea... Firstly, i am always looking to make another buck.. so a little extra hash every year would be nice.... Secondly, i was thinking if the miners paid themselves off in 13 months, then it could generate an $900-1,000 USD after it paid itself off.. just going off the 0.12cent power rate... Thirdly, i have been contemplating upping my solar system to 3-4kW system to offset my entire house cost a month in electricity.. since summer months here in sunny Florida are killing us and every year they have been pushing to raise the solar cost and its only bound to increase soon.. they are proposing to jump it from 0.12 to 0.15 by 2017... So i would like to get ahead of the curve, but the time of payoff on such a size system takes longer the larger it is.. due to invertors and wiring cost increasing as size increases to accommodate it all, so if anything if i ran enough bitcoin miners to use the solar installed it would drop the payback to 1-2 years instead of multiple years... so if anything it could be a way to pay off solar install much much quicker.. Fourthly, after the solar has been offset by profit from bitcoin mining, the electricity at that point would be relatively cost-less to run if i kept them within the production range of the solar system.. so in my mind that equals profit.. or would the profit depreciate so much in the future to not really let this all work out?? Florida does offer net-metering even though i dont utilize it currently, so grid usage at night would be offset by solar production during the day if i went that route.. That will help you with difficulty, and there are some projections for what it will be, but I'd say at a minimum consider the last year X 4 in your calculations for difficulty. Companies want to put a miner in every phone, toaster, and POS device. It will get even bigger, even faster. If you figured out a way to get free power, or even power that was .03 you can do it, but you have to consider all of the incidentals. Power Distribution units - I build my own and I still have several hundred dollars in parts. I took a dining room table, mounted a sub panel to it, and mounted receptacles all around it. All 240 except a 4 plug 120. I made all of the cables going to the PSUs, and run all server units with B/O boards purchased from people here, sidehack I get 2000 watt units from and Finsky I get 2880s. Cables going form the PSUs to the miners. I couldn't build them as cheap as they can. I buy all of those. You have to deal with the heat. Think exhaust, dont think AC, but more like exhaust fans in some kind of tunnel or duct-work from the exit side of your miners. Don't keep anything flammable around your miners, and do keep a fire extinguisher. You need a 100 base network switch with enough ports so you don't have to buy another one right away. You can find deals on used ones in the marketplace here on the forum. You will need racks for your miners, get metal ones. The wire racks everyone has pictures of are less than 100 bucks at Lowes and that is the largets they sell. For only 3 or 4 miners or even 8-10 look at shoe racks. They are great, actually "boot racks". do more reading than you ever have in your life and never stop asking questions |

Bitcoin / Hardware / Re: How to create custom exhaust duct work to remove heat from room
|
on: May 27, 2015, 01:00:33 AM
|

Exhaust is the key, not inlet AC. That is no good, you must exhaust.
I assure you, I have worked with DDT aka down draft tables for plasma cutting systems, along with nice Donaldson and every other brand of Fume Collector. You must exhaust.
Picture a 1 room apartment with your standard rack of miners with the exhaust end towards open window(s)
You can fill that rack with miners, S3s, S4s, S5s, SP20s, a good mix.
If you blow on the front with your nice expensive AC unit at full blast, the heat still rises, condensation builds up on electronic parts, you have hot and cold spots, and you do not help much.
Now take one decent fan and put it at the window blowing out. BOOM all that miner heat gets sucked / drawn, whatever you want to call it, but it is removed so easy, but you must have the fan in the window. Go one step further and make or buy some duct to semi or fully enclose the exhaust side of the miners, create some pressure to your exhaust fan at the window, BOOM now you are cooking.
There is no place in a mining setup for AC until you have properly handled your exhaust, and even then, the money you spend, the condensation, the hot spots, etc, it is worse that nothing if you do not have a decent exhaust.
I have one fan exhausting out a door, and one fan all the way across my room at a window for makeup air. I've fallen asleep in there it is so cool and that has been on 87 - 90 degree days we've had.
One fan cost me $125 and it is a nice newer one made for commercial use. It isn't "Industrial" we have those at work and it would be overkill.
Please forget the AC, do not use plastic duct, use metal, and it doesn't have to be beautiful, you can tape (use the right tape) the metal pieces together to make duct, and use a few 1X whatever on the outside for a makeshift frame and seriously tape it together until you want to do something better.
You will be much happier and with cross flow inlet - outlet setups like this you will be ambient with a sweet breeze.
Don't believe me? Try it with a couple of fans, one inlet and one outlet, but remember, they do not need to be close. One on one side of the room, one on the other.
Oh if possible keep your exhaust fan high and your inlet fan low. Heat rises. Use the natural way things flow / work to your advantage. Don't fight the flow with AC, help the exhaust with a fan.

My first choice would be on a mountain in Wyoming, but I was just this evening discussing Alaska with some folks.
Also, I definitely did no real work this weekend. I mean I finally fixed the windows in my Jeep, but I didn't really work on miners at all. Tomorrow I may do some more testing on noise limits or something on the Compac, and work on the L-board for two-chip base Amita testing. Or I might just sit around and talk about awesome stuff with Novak all day. Who knows.
I have told my kids and anyone who will listen how beautiful Wyoming is. I spent a 4th of July weekend tromping through the Grand Tetons. It could easily be spiritual. I lived in Livingston, Montana for about 3 months. Too cold. I like it in the 60s and it is an amazing thing to walk out your door and see land in that way. I live in Oklahoma, and it has been the most unusual place I have ever lived. Tornadoes don't bother me, I grew up with them in another state so I am used to them, but the weather changes are extremely unusual. I was told today we have also overtaken California as the earthquake capitol of the US. I have an app which shows the earthquakes for a variable amount of time, say you want to see the significant geological activity for a week displayed by some sweet graphics, Oklahoma looks like throwing rocks in water. Sidehack you and Novac sound like you have some of the best jobs int he world. I used to say I would like to work in a beta datacenter for a huge tech company, but I was wrong. You guys have the best jobs. If you guys decide to start keeping an order list please put me on it. I want at least 2 of each USBminers and anything bigger. If you sell boards, I want those as well if possible. I will not ask the question that other guy asked either regarding lengths of time  |

A successful coin will emerge, but it will be one which doesn't need a fair launch.
Crazy concept I know but it will be a coin which encompasses the main features we need without the bloat associated with making people money.
Open your mind to a coin which has a purpose of accomplishing usability and profitability without an ever increasing entrance investment. A coin which has several main goals and none of which are to make any single group rich. A coin which makes a pump n dump of no value to the scammers who walk among us ruining good technology.
Start with a goal of changing the monetary system without making someone else rich.
An alternative would be to take a good coin like Monero and work backwards removing the aspects which make people wealthy.
It is the mindset which sets the goals, and the goals which are greed based that lead to the crypto environment we have.
I believe to make a coin which will actually "go to the moon" in terms of adoption, you need to first stop creating coins to make money and develop to help humanity.
No, not another "charity" coin think bigger.
Think of an idea more along the lines of allowing someone to enter the coin's community at the same "cost" for the first and 500 millionth person. No more, no less.
Think of a coin which removes the ability of these so called "exchanges" to work with scammers to manipulate price so they not only pump n dump once, but they do it over, and over, and over to the same coin until there are a few people left holding a ton of worthless crap and the dev moves on because he cannot make his wages.
Once you create a coin which is unaffected by human greed, manipulation from pumpers, and whales you have a beginning to a coin which will be truly adopted.
Before anyone says "this is crypto, it is ALL about making money", "get out if you don't like it", or my favorite is "This is crypto, maybe it isn't for you"... Those people are the ones defining the use of crypto and in doing so, ruining what does still have a chance to change the world for the better. Those people are turning crypto into exactly what bitcoin was invented to work against. This scene is not crypto, this is what greed, scammers, and a few scummy people have turned it into.
Satoshi the group, the man, whatever had the right intentions, but it is time for a rewrite to remove the manipulation.
Only a truly selfless community who wish to accomplish much more than "making money" will succeed.
Everything else is just a shiny quarter vying for our attention and until we as a community decide to stop filling the pockets of the trash who currently define this scene it will continue down the road to be the very thing we rally against.
Making money is great. I could sure use a great deal more.
Changing the world and re-inventing the original intentions of what bitcoin was supposed to be? That is the stuff of true Legends we should all aspire to support and achieve.
Do not idolize someone because they are wealthy in any coin. Idolize someone because they are making, helping, promoting a "good" coin or service which helps everyone even if they are not holding the coin, a coin which helps everyone, period.

|
on: May 16, 2015, 06:36:53 PM

Many people have reported less Power supply failures with 220 / 240.
Personally, I think it is because many of those people are also using server power supplies @ 240 and have already burned up the POS Bitmain PSU, but I ran one S4 on 110 and 240 and had an equal number of Bitmain stock power supply failures.
1. I would not overclock using stock PSU on either input voltage
2. I would replace the stock PSU as quickly as possible with a server model, IE DPS2000BB works beautifully and can be made to fit inside the unit, albeit a bit messy and I would never resell it that way.
If you are ever looking at S4+ units, they are 220 / 240 ONLY and have crap QC on the power supply.

We certainly need the source posted.
At release of coin and each feature release it is mandatory to post source, Windows 32/64 Wallet, Mac Wallet, and Linux 64 Wallet.
This along with a lack of some other basic communications, "a few" people running multiple nodes and prior purchases dumping are why the price is so low.
Slayer, I have great respect for your work if it has all been you, but if you do not foster adoption within this small community of people who are begging for help with setup of masternode, and other basic items, IE posting source, etc, then you are releasing features which very few will use. At some point no matter how sincere you are people will move on.
In my opinion you should polish the feature set you have along with putting source up with the correct dependencies included or clear instructions for compiling and loading them. Make it easy for the less technically inclined to use, or it will not be used by those people and they are who you want.
I am telling you this because I hope you are sincere and these are simple mistakes of priority. I understand you wanted to get the market open, I heard people saying I2P is the right way, but at some point it begins to look like a feature pump to sell a few coins.
I think I can write some things to help, but I am losing confidence your priorities are not as geared to having more people involved in the coin. I am not a huge Sling holder at this point for the simple reason I feel like new features released without Technical Support for basic operations is not a good thing. You isolate people in doing this.
Post the source for us to build ourselves and work through the bugs of the features you have with wallet update links including versions in the OP. Be meticulous in creating how-to documents which are specific to sling and watch many people take another look.
Again, great concepts, great ideas, and you delivered most things when you said you would.
Unfortunately some of the best technologies ever invented were left to waste because they were not supported. Do not let that happen to Sling.
If anyone says all Alts are dead, they haven't seen the Alt that grabs the most. Many inexperienced crypto people will latch on a coin that doesn't have any real features, think paycoin (XPY), but they made it attractive to use because of ease of use. Sling is easy to use, configure, etc, once you know how. Get more people on-board by polishing and waxing what you have now.

I have also put a little smaller than Phillip's hash on mmpool in interest of the UNO MM. I also put a couple on xpool.ca for the same reason.
The DGM carries a much higher part in the "normal" mining at mmpool. I am curious how it ends up.
What do you think the price of uno will do to not only the price of the coin, but the hashrate at pools like mmpool?
Will the "bigger" pools like elgius, slush, ant, all start carrying an alt with a good value?
