this style of selling only feeds into bitmain
btw I am not being anti bitmain this is simple economics.
bitmain just cranks out cheap s9is sells the shit out of them.
and here is the kicker bitmain does not even have to design its next chip just buy each new miner from Halong ,Innosilicon, Avalon or GMO
and reverse engineer it then sell it at a lower price.
EVEN better bribe a guy on the inside and put the chip out faster then the real builder like they did to the sia asic builders.
That said I grabbed 2 cheap s9i's to test my solar idea out.
I may be able to sell a solar package for an s9i at a good price.
certainly a 2 board s9i on the cheap

In the long run wouldn't the B2 miner be more profitable? Let's say after the difficulty spikes because of the new miners. Thinking 2-3 years ahead.
yeah maybe if it does not break. the 2 mistakes they are doing : 1) not shipping now 2) not offering a 1000 watt miner along with a 2000 watt miner they would have been better off build some 1000 watt 13th miners along with some 2000 watt 26 th miners and simply selling them once they are available. This moron preorder falls right into the hands of bitmain. r Economically 2 s9i in hand for 1265 is so much better |

Hey Phil, this seems like a great idea if you can keep the cost down. Let me know if you're serious about it. I know many people in Asia that would like this if it makes sense economically. We get alot of sun all year round!
Yeah we will be building a prototype soon. The key will be how many panels we can get "new old stock" panels really cheap at auction. This means 210 to 230 watts a panel panels are about 2 by 4 We can get a (dc or ac) to dc power supply rated at 1200 watts this allows 24 hour operation and tied to the grid We can get a dc to dc power supply rated at 1200 watts this is for Day light mining only. So a 6 panel 1 power supply can not do the s9 or 841 or t1 but it could do an L3+ or a 2 board s9 We will be testing 8 panel 2 power supply setup on and off grid We will be testing 6 panel 1 power supply setup on and off grid |

As much as I wanted to get this unit today I purchased 2 s9i's for 1265 usd shipped to my home in USA NJ.
so I get 28th for 1265 moq of 1
and this unit is 17th for 1600 moq of 100 pieces
Frankly I owned 5 t1's and I liked them I sold off 2 and kept 3.
But the pricing tactics of bitmain are brutal.
28th at .11 watts is 3100 watts
17 th at .09 watts is 1530 watts
34 th at .09 watts is 3060 watts
so at equal power the t2 may do 34th vs 28th for the s9i
cost t2 3200 plus shipping is 3400 usd
cost s9i 1265 with shipping
I am 2000usd less with equal power use
and 6th more with the t2 6th earns about 78 a month so I need more then 25 months to make the T2 a better deal.
I realize that can change but the T2 is overpriced even if it is better the the s9i.

Just back from long consulting work with limited Internet access and catching up with the thread now.
In my inbox, saw a few interesting emails... one of them... Bitmain firesales... all SHA256 miners are at $7xx and $6xx (without PSU) -- are we looking at the coming of the mega-ASICs-miner?
Knowing how Bitmain works.... are we starring at a possible 100TH miner at 1000w by the end of the year?
Make sure to answer the invite from generalt Free contest for a silver coin. No way will a 100th miner with 1000 watts goes on sale. I think they have a 1300 watt 19th machine |

Direct manipulation of the config files can cause hardware damage.
I suppose there would the pedal to the metal over clocking if some got in via ssh. |

Given how Halong has behaved from day-1, seems on-par with how they run things.
Kudos for them actually getting product out the door that mostly/does work. Jeers for their support and openness.
-ck did good work with the firmware. I can get it to do 1300 watts at 14.4 th and fan is 38% in an 80f room. But ssh is locked out . Can not mine bch and we need more pools. Still for the most part I like it. |
|
|
|
Yet another shitty feature of the T1, locking you out of the OS on something you own. Even bitmain allows this.
I wonder why they do this? |
|
|
|
Time for the S11+mini!!
maybe . I really hope they go lower watts with it. I have space I do not have a ton of cheap power available I would like to use a piece of gear that does 800 watts and mines 12000 th that would be 0.0667 watts a gh most likely it will use 1300 watts and do 18th which is 0.0722 watts a gh. the t1 does 14.2 th at 1300 watts which is 0.0915 watts |
|
|
|

massive dump of gear . 750 -100 coupon = 650 for an s9 add back ship 750 a unit.

Understood. It sure distorts our diff% when they go away. I know it is just a warm fuzzy stat but going back to 21PH to find a block is not going to occur in the statistical timeframe the difficulty % reflects. Just an observation. Not a complaint.
More hashrate = more shares = more blocks = more frequent payouts = less variance. I am happy about that. We are getting our share we worked anyway, so everything is fair. As long as we hit a block with them. What is the impact when we go back to 21PH when they leave before we hit a block? I am glad they are on. But it is only beneficial if we hit while they are on. If this is incorrect I am open to being corrected, please. Main point is the statistical luck is what it is. This major variance in hash just distorts diff% figures and expectations may be skewed. they collect when they leave. just as same as anyone else. you have a classic the glass is half empty mindset. you are correct but it simply is the attitude of a pessimist. BTW they have hit multiple blocks if I am correct. |

check this numbers out, I don't know if this is safe or I should turn them off or add an additinal AC I am in a very hot area even with ac on and fan taking heat out this is my numbers https://prnt.sc/jqfoe3please advice, also what is the max tempreture that I can consider safe to operate, what happen on over heat, miners burn? shutdown? hardware changed since my last water cooled miner, this new firmware sucks I cannot lower volt or hashrate or anything, its autotuning You are borderline. What is the room temp? |

I think the only household like item that would work for mining is if they put mining chips directly into solar cells and it is probably gonna be a small amount of mining chips per solar cell since solar generates so little power. The chips should be working 24/7 and housed waterproof somehow lol. Or better still, do wat tesla does and put solar cells into roofing with the chips. That might actually work, where the solar is located on the roof outside and generates electricity and the chips are located on the inside of the house and creates heat and btc. The good news is that it will never turn unprofitable haha.

Just don't forget that the support-component costs scale per miner, not per chip, so tacking on controls and power regulation for "a few chips" costs roughly the same as for a few dozen chips which gives the "few chips" miner a much higher initial cost per hash.
You know I'm not a fan of super high power miners, but there are practical limits to how small a miner can be and still be cost-effective.

This doesn't even look like science-fiction right now, it is more of a fantasy genre.
The solar cell manufacturers can't even reliably build-in the temperature sensors or other environmental sensors. Various radio-equipment manufacturers still can't reliably integrate electronics with antennas, even though the radio equipment isn't required to be maximally exposed to the elements.
Quite a few roof-based solar installs don't survive single year without sprouting leaks or other problems. Having recently seen the quality of workmanship on some of the solar power installations I observe a market regression in quality. Lots of them will require major repairs or will be completely torn down in the coming years.
Currently the flat, thin magnetics that would be required for power regulators are very expensive and are used only in high-end high-power CPU chips.
I'm not the one that would try to prohibit daydreaming, but people need to be aware of the distinction between dreams and reality. Otherwise it gets into the realm of either psychiatry or fraud.

the word [b]may[/b] covers a lot of bases.
My device won't be doing that.
It would involve panels and dc to dc invertors .
Most of all it would be a pay one price getting you panels ,invertors, and you use a miner on the market now.
Most people would no have space for my setup since panels are 2 by 4 and give 220 watts. so to run a s9 at 1300 watts you need 7 panels maybe 8.
which is a 4 by 16 foot space. The idea of chips built into a panel may work has nothing to do with what I am looking to develop.
your power cost is up front and you get about 1-2 dollars a day back in power for many years.
would work nicely with an avalon 841 since warranty is 2 years.
you would need space in your back yard to run the gear. panels would install like this
these are 190 watt panels so 8 would do 1 s-9 for 5 hours a day or about 8kwatts a day

So the avalon 841 with a two year warranty and your setup never stops earning since power is paid up front.
But 8 panels = 16 foot wide and proper sunlight. So your customer base is limited.

@ yankees yes I can not put this in my own back yard I simply have too much shade.
Not enough space for eight panels 2x4 each.
But If I can get an avalon 7nm using 400,500,600 watt settings this is a viable idea.
At the moment the avalon 841 can be reduced just under 1000 watts at a low power setting.
Ideally a sha miner that has 3 settings of 400 500 600 watts would allow me to build a 4 panel device vs an 8 panel setup
the key to this is I am hoping that 7nm devices under 1000 watts are built by avalon.
At 2112 my setups will not involve roof mounts or permits since the mounts will be portable.
off grid allows this in most any state.

DC to DC inverters?
Frankly, what you wrote isn't even sounding sane.
Trying to come up with a workable explanation:
1) DC to AC inverters
2) haul power off the field to some shed in a shade
3) rectify AC and regulate DC
4) feed miners short distance in the shed
could probably work if you buy recycled/re-manufactured/B-stock parts and still somehow manage to get politically-motivated subsidies for the cost.
I understand that not mounting on the roof would greatly simplify inspection for fire and electrical safety. But you would still require some inspection if planning on connecting to the grid or use the power in the residence/business abutting the field where all that is installed.
On a second thought I even don't think that the inspection would be easier to pass. Fire safety definitely easier; but the electrical safety would be worse: the field mounted electrical stuff would need to be made child-safe. I heard second-hand stories about that type of safety inspections and various lawsuits related to leaving dangerous equipment unattended.

Unless you have children, any children getting hurt would be trespassing anyway so sucks to them. Same reason I don't understand requiring extensive fencing around a backyard pool to keep other people's kids from drowning themselves - discipline is supposed to do that for me.
Anyway, I think the idea is to have a small enclosure (a doghouse was mentioned?) probably right at the panel, to reduce the need for inverters or long wire runs. Grid tie negates some of that, but if it's not required all you'd need is internet access and nothing else travels more than a few feet. Depending on how panels are rigged, voltages could stay relatively low/safe.

No dc to dc not dc to ac. They exist and you would end up feeding 24 dc into 12 dc output.
They have one that can tie to the grid so it is techniqucally an inverter / converter.
Or a 12 volt output power supply that can use dc or ac.
It is more costly then the straight dc to dc converter. Which would only run in daylight.
You need to understand the value is getting. Up to 20 years of power with no additional cost.
And that it is not for an apartment dweller . But it is for a person with some land,
If you are concerned about kids fucking with it then fence it like a dog run. After all the miner will be sitting in a doghouse :D
I will be starting a new thread on this soon. I brought it up here as we will be testing it the next few weeks.
Avalon says they want newer ways of using chips when they make the 7nm well a 400 500 600 watt miner would be good for this idea.

I am in the midst of developing a power supply to be used primarily for mining.
It can be off grid mining in Daylight only.
It can come with grid tie option more costly
If can be used with batteries more costly.
First option Would be call "Daylight mining" option
Goal would be to have either 880 watt or 1760 watt setup
Would use a dc to dc power supply designed to convert the panels power to 12 volts.
Second option Is yet to be name but would have a more expensive dc or ac to dc power supply . It would mine for free in the daylight hours and you could pay for power at night or when profits are low just mine in the daylight.
Third option would be a battery pack but is costly and hard to implement. We may not build it at all.
Buysolar and I will be testing this over the next few weeks.
With an avalon 841
a two board s-9
and a L3+ note to mods please do not move this to alt coins due to the L3+ testing it is all I have that will let me test at lower power. note maybe I will test with a 1 board s-9 instead.
This idea is to pay one price for years and years and years of free power. the dc+ac to dc power supply has a five year warranty the solar panels last more then 10 years.
More to come.

I have been busy with buysolar we have a few solar projects in the works.
a 6 acre piece of land to develop ----- small chance has issues for permits
a 73 acre piece of land to develop ---- small chance as it is a bigger complex project with at least 5 people involved not sure if we can figure out the how to split coins etc.
a small 1000-1500 watt setup to sell --- this is at least going to have a prototype built the idea here is to allow anyone with some land to do an off grid without a permit with or without battery.
without battery is cheaper to setup but only runs in daylight
with battery is more costly to setup but we may offer it as an option.
grid tie in is costly and needs permits.
In any case we would offer it with an L3+ or 2 L3+ simply due to the easy down clock .
phil - if one of your business plans is to provide l3+ hosted services, keep me in mind. If we ever get the 73 acre piece developed I think we would take in older miners. We may just do day light mining. 4 to 7 hours per day. as long as daylight is strong enough. this could be viable for any working gear that does not make money mining. take an L3+ it earns about $2.50 a day and uses about 700 watts on a volt saver setting so 700 x 24 = 17 kwatts a day so if you pay 14 cents = 2.38 you make 12 cents. Send it to us we split coins mined , it would be daylight mining so 5/24 = 0.20833 x $2.50 = 52 cents to split or 26 cents each Just not sure if we get it developed. Any gear close to break even would turn a profit. |
