The Ethereum is not rest in peace yet. Its price is multi day high. It still has a strong community and people support it.
Yep. We are driving the price up. Not whales lmao. Where the trolls at now that we're back to where we were? Litecoin his this price once. And it was thanks to bitcoin as it simply tagged along during its gold price peak. This is completely detached from BTC and that's why its so amazing. |

Selling these two items used. Both are in excellent condition and perfect working order. I am looking for offers in USD or BTC. If escrow is requested i have no problem using one but i do not expect to incur the fee's associated nor the shipping cost. These are buyer responsibility.
-Evga GTX 980 ACX 2.0 $299
Used for less than a year, still has around 4 years left on the warranty i believe.
-ASUS GTX 980 DCU2 $199
Have had this for about 3 years. Still 2 years on that warranty.
Both are great cards. Makes another computer i have with a 280x look stupid. Also while the 780 is a gen older than the 980... its only around 20% slower from what iv'e seen. My 780 should easily rival a current 970 for much less.
Again BTC or USD is fine.
I think there's a typo with the -ASUS GTX 980 DCU2 $199 Thank you! I'll correct. It is a 780 Bump |

ETH drama is amazing. Finally bye bye eth
It might last longer than you think. The price is $12 now. It rose from $10 and it is still rising. It is amazing. Not amazing my friend, ETH is made for fast profit only, there are some whales in, and the whales wants the price pumping and dumping to make tons of money like they are doing since this trashcoin born ETH hacked, DAO hacked? serious? accident or purposely to make the prices go down, whales buy cheap and then pump the prices again....... I seem to recall fontos doing the same thing to LTC 4 years ago. But you probably weren't even in the game then. Prove more of your ignorange. Please lmao. |

Dropped down to .01, then to .06, now its back to .08. These ignorants are missing out on the largest buyers market in altcoin history. Salty ass kidz. |

Lol litecoin is shit. Has been for years. Bitcoin is living off its high-self. Its been so bastardized by centralized mining its only a matter of time before it fails. Fools forget that now all bitcoin mining is in the hands of like 10 groups of large mining farms. These farms rule bitcoin. So i'm confused how you think its not vulnerable. It will fail. Its a mathematical fact.
Ethereum put mining power back into the hands of the people. The way it should be. Until litecoin and bitcoin both migrate back towards de-centralized mining. I will not deal with them. It looks as tho eth will bounce back, even DAO has come up a small margin. You think people wont buy DAO when its the absolute lowest its even been lmao. They call that a buyers market.
To the fool who said if we return the money claiming of ETH overlord magic. Do you know how majority rule works? Majority of eth holders would like their coin back. Which overrules the handful of hackers who broke the laws of E-currency.

Depends, whoever runs IT at your company will be able to see it.
And you're not looking at a big payout with only 1 kW, especially if you don't have the ASIC and PSU to begin with.
Constant traffic on weekends and non working hours will look suspicious.
I don't believe our IT personal would really monitor traffic like this... but i don't know. Personally he cant even keep the network up most days. I would run an ASIC, probably an S5. I can't stress enough that people need to read original posts. I said right there we all run our own space heaters. This is merely taking the place of a space heater. And since electricity converts into heat energy so wonderfully, it will probably work just as good. Hey worst case scenario i can run a Pi and dongle it. This would eliminate network traffic altogether. How much traffic is generated typically in a day? I read your original post and I don't see how my answer deviates from it. IT sees everything if you're connected to your company's network. It's very stupid to bite the the hand that feeds you. You seem very stuck on being a parent figure rather than giving me the info i asked for. So either contribute to this thread and provide that answer. Or see yourself out of the thread. It's that simple. While i'm very aware of the fact that i don't need to explain myself to you, as mentioned in the earlier post, but they will not have a problem with what i am doing locally. But i work for a worldwide company that shares a vpn with many other facilities across the world. If i had to guess, the amount of computers on this network is in the thousands. People work night, weekends, connect directly to the network from home, all kinds of traffic at all hours. I find it very hard to believe that one man would be able to point out random packets moving across one of 50 facilities, on one computer out of 1000, on a connection over 100mb. Especially considering my VPN software is connected from my home computer almost all the time. I can connect offsite from onsite and visa versa. The VPN software i'm using btw, was banned by the company, and yet they failed to notice iv'e been using it for over 1.5 years. To sound even more redundant to a point I shouldn't be explaining to you, as mentioned, I can use a cellular dongle, or tether, cutting myself off from the network altogether.... but you must have read that too. I can see why you might ignore that tidbit as it shatters your argument to pieces. Cheers. Also forget the information i was looking for (bandwidth data), as i'm tracking it right now through my rig anyways. Thanks for.... well nothing really. Unsure what you're looking for in this thread, you basically answered all the questions you had yourself. Why are you asking our thoughts about "looking fishy to IT" if you plan on not using their network? You seem to be pretty convinced that the appropriate thing to do is to steal from your employer, so I'm not sure what you're looking for here. You're a fucking idiot. End of story. I said multiple times with their permission. I was looking for bandwidth numbers. An idea of traffic in bytes. Simple as fuck. But you seem convinced i'm steeling when i'm not. They will let me run a miner as a space-heater. No problem. God i hate repeating myself. Maybe this time with a few more harsh words it will get through that bullet proof head of yours. Or maybe you will continue to troll harder. Time will tell. The point of all of this. Management has final say on anything. I have my personal bosses permission. He doesn't give a fuck. Now that doesn't mean it wont piss off IT. And make waves amongst managers. All i was trying avoid. But no the trolls come out. GO AWAY AND FIND SOMETHING TO DO WITH YOUR TIME. |

A) The fans are too noisy and will attract everyone's attention
B) If caught you will be fired and possibly charged with petty theft (of electricity)
C) Is that worth ~ 6USD /day to you?
This is not so much an issue. Any of these. In-fact i'd probably disclose this information. Btw an S5 with some decent cooler master fans isn't loud at all. So in respect to point C. Yes. Because A,B don't apply. |

Hey there guys,
I work in a large office building that is poorly heated. Generally in colder months they allow people to run their own space heaters in their respective areas. Most of the space heaters around here i see are in the 1000w area so not too indifferent from an asic.
If i ran a smaller asic in my area and used it like a space heater... would the traffic from the mining generate any weird looking traffic on IT's end? If so is there any way to mask that traffic? Now we have hundreds of computers and an open wifi ap. So there is all kinds of traffic here to begin with. But at night when no one is here.. i could see something like that looking fishy to IT. What are your thoughts?
Thanks in advance.

I'm running 10kW of mining gear and ~5kW of grid tied solar. Solar supplies about 10-15% of total daily consumption, in Florida. Realistically, I would need more than a 50-60kW solar array, at minimum, to cover 240kWh daily use. So you either need a shit ton of expensive battery or are going to be grid tied, back feeding to power company most of your generated power, only to buy it back later at a higher price. So you need at least ~6X in solar what your intended load will be if located in a 4 sun/hr geo zone.
This is good info thanks. The only issue is selling power back is not an option at all. So I'm left with battery and simply having downtime for powerless hours. The battery only serves to store what the miner doesn't use during that day off the solar. It could run maybe a few hours after light and then I'll need to switch over to wall power. A arduino unit controlling a physical relay switch could handle a task like this. |

I would keep the overall setup as simple as possible using some off the shelf modules from Ali Express.
Solar Panels >>>> MPPT Charge Controller >>>> Battery Bank >>>> Buck Converter >>>> Miner
Rich
Yes this is what i'm thinking, except with the addition of a direct loop from the panels to the buck converter to bypass charging in the day cycle. If the batteries are low for some reason (bad math on my part or a few shitty days in a row) I would want the Panel to prioritize powering the miner over charging dead batteries. So the circuit would resemble this: Solar Panels >>>> MPPT Charge Controller >>>> Battery Bank >>>> Buck Converter >>>> Miner | | | | >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> This gives the buck converter the ability to run off battery or pure solar. This might require a second buck converter in parallel with the existing. I could also run a Arduino post second buck converter and write a simple python program to cut power to the miner in the event its running low on power from both sources, this prevents unexpected power loss and unintended low voltages going to the miner. |

Ja they are massive power -- which in turn means massive weight. As is several hundred to over 1k Lbs each so plan on needing an engine hoist or other heavy lift device to handle them...
Indeed. Forklifts have massive counter-weights on them so they don't tip over when they lift a heavy load. Electric fork-lifts tend to use these heavy batteries to their advantage. |

If you can make a purpose built building for battery storage, look into some Good used/Refurbished forklift batteries, Extremely durable if properly maintained. They are huge, heavy, clumsy to move, but they should last forever in an application like yours with a good charge controller and proper battery maintenance. Frequent battery replacement will negate any cost savings made by solar.
Go big!
I have one of questionable strength/life left in it that i acquired for nothing. Can't find any marking or stickers on it but it is a 36v battery with a few dead cells, you can bypass/hack off terminals to the dead cells and make it a 24v battery. That's how i have mine set up, it's @ my friends hunting cabin in Mexico. I have a cheap $40 30amp charge controller and 5x 100 watt rated panels(supposedly) People are rarely there and its allways charged.
If you aquire a 36v battery and many cells are dead you can make it a 12v battery, . Whatever suits you needs. Right now i'm looking @ one that looks kinda funky that survived a warehouse fire intact'ish. Look around, these are out there.
Good luck, sounds like a fun project, free power makes a few miners mining solo more interesting.
A few people mentioned this to me in the past too! Forklift batteries are usually a pain for any company to have to deal with ;P I could def take them off their hands. |

Interesting news boys. Ran a mock test on my solar panel i made.
These cells are claimed to run around 0.6v per cell at roughly 6 amps totaling around 3.6 watts each.
I made a 4x9 array totaling 36 cells all wired in series to match a 18v minimum inverter.
Some measurements i took today...
@9AM with zero cloud cover i recorded : 22v @ 6.5 amps!!!! That's 143 watts total and 3.97~ watts per cell!
@11:30AM with zero cloud cover i recorded : 22.2v @ 7.77 amps!!! That's 172.5 watts total and 4.79 watts per cell!!!
That's insanely good!
I should mention the other amazing side of these cells is; they are rough 165 micron thick or .006" thick, Semi-flexible to around 30 degrees bend, are relatively space saving in area compared to conventional pv cells, and weigh virtually nothing.
This panel is only 45" x 20"
Once i finish my solar tracker i should be able to get some real-time data that maximizes its output.

Hey guys, I'm wondering if anyone knows how a 12v Deep Cycle battery would do running a miner like an S5? Assume a 590 Watt draw just as a baseline. Is it as simple as pulling watt hours from the battery? IE an S5 running @ 12v using 590 watts is pulling roughly 50 AMP. Is it as simple to say that if the battery is 600 AMP it would provide 600/50= 12 hours? Deep cycle's don't really like to drop below 50% for long life. So 6 hours? I'm more concerned with my concept being incorrect than actual data numbers here.
I've seen plenty of naysayers shunning the use of batteries as they typically have voltage drop as load is applied and battery resistance rises. That is how automotive batteries work, however deep cycle are specifically designed to maintain voltage across a usage curve with a steep drop-off and resistance increase generally happening around the 80% drain mark.
Happy hunting
S5 and 165 chips batches of S7 are not happy of voltage variance caused by dis/charging. Fully charged battery at cycle charge is 14.6V, but fully discharged battery has 10.5V. S5 likes 12V at full speed, if you put 14.6V you may overheat it, side effect is much worser efficiency, growing to S3 level. Opposite, if you keep S5 running at low voltage, it will stop hashing or you need to slow it down. My S5 can work from 9V, but at slowest seed of 100MHz. High efficiency DC/DC converter will stabilize your voltage, but it is more conversion loss and more expenses. 135 chip version of S7 has DC/DC convertor, so it can be used at voltages 11-16V. I did undervolted version of S7 which can be used from 10V. Yeah i covered that here; https://bitcointalk.org/index.php?topic=1429779.msg14461340#msg14461340 More or less i would run something like this http://www.ebay.com/itm/LTC3780-DC-5V-32V-to-1V-30V-10A-Automatic-Step-Up-Down-Regulator-Charging-Module-/322049388287?_trksid=p2141725.m3641.l6368but a bit more powerful obviously. Dirt cheap and efficient. I want to be clear here too, i don't want to just run on low voltages, i want to undervolt/clock the unit itself to increase efficiency and decrease power usage. If the S7 has dc/dc converters, it sounds like that would bypass any undervolt i would do? Or does it merely run DC/DC converters to run the control board, while allowing the chips to operate at lower voltages. philipma1957 Do altcoins still rock mainly ATI/AMD cards? I don't have any of those but i have a few top of the line model nVidia's. GTX 980, 780, a couple more. |

Don't forget to consider the charge efficiency of your batteries, which can be as low as 2/3 - which is to say, 900Ah in to get 600Ah out.
This can be true but that is typical with quick charges on duty cycle batteries. A marine battery is not a deep cycle battery. Those are somewhat hybrids. On a pure deep cycle where you only want to discharge maybe 30% of the battery max, you get a much slower charge rate and the efficiency is much higher. |
