Avalon pursuing 7nm technology

[sidehack]

A space heater would work better (economically, for the consumer), especially if you used a simple SBC with wi-fi for thermostat controls. The added cost would be divided out among at least an order of magnitude greater hashrate, and the heat wouldn't be an undesired side effect, and the power consumption would already be a necessity.

The cost of a core regulator for one chip is approximately equal to the cost of one chip. But with string design, the cost of a core regulator for ten chips is approximately equal to the cost of one chip. The brain isn't the only part we have to consider the added expense of.

Looks like they may abandon or shift from mining gear

This looks like AI and not crypto.
We dont need more mining gear actually. There is a fixed amount of btc released every 10mins iirc. Stronger gear just means everyone has to spend more and upgrade and still get the same amount of btc being released.

Canaan only made 56million usd profit in the whole of 2017 which is a record year of mining. They made 7 times lesser, meaning 8 million usd profit in 2016. It isnt that much. The market isnt that big.

21.com had a similar idea a while ago, but seem to have dropped off the map.

I forget who it was that had the idea of a "smart lightbulb" with a miner chip in it, but haven't seen that come to market.

I believe the whole "consumer device with a mining chip in it" concept is a non-starter, due to power usage (forget Green certification) and requirement for Internet access (lots of folks that don't have WiFi of any form or any interest in it) and the additional cost of such an item.

Their biggest issue would be most people are not interested in mining. The average person will not take the trouble to configure everything or even if it was somehow auto-configured, they would not be willing to pay even abit more for that chip to make like 2-3 dollars a month lol. Not worth the hassle and these people do not want bitcoin. Furthermore, with mining being competitive now, they can only sell those products with mining chips to countries with low electricity rate.

Those interested in mining would want strong efficient miners and not 1 chip in each product lol. Basically, their product has no real demand.

Fuck miners my Samsung tv can run the entire block chain.

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.

This is a good idea.  A long term rebate never ending.  Just declining a bit.

Avalon would do well with this idea.

my partner buysolar and I are looking to develop a Pay One Price  solar miner.

Your have something here.  Build chips into a panel and mine a bit. Not bad.

Pay one price solar miner? Buy solar is a solar company I guess

Buysolar is a forum miner here.

He owns a solar install company.

We want to develop a solar powered mining device.

Building chips into panel may work.

[sidehack]

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 may 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

[TheYankeesWin!]

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.

[philipma1957]

@ 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.

Edit: Additional posts preserved for further reference.

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

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.

Phil, i met Sky at the training at Canaan in Beijing last April. I believe solar is a very powerful and possible idea for south american and central american countries. Excited to see the develop of this, and if you need to test this here just let me know Sky has my contact info

I do have a prototype  that can hold 2 L3+ or 1 S9i

It is outdoors a doghouse available at Amazon.com

I am going to take a photo or two of it now.

about 28 inches long

https://i.imgur.com/Q5PMo2x.jpg

about 25 inches high note air intake

https://i.imgur.com/Jgo42qb.jpg

note air leaving
https://i.imgur.com/th1HHmF.jpg

pair of L3+
https://i.imgur.com/vERn9pS.jpg

could use 1 s9i I am waiting to get some to check how well it cools.

2 L3+  doing voltage mod pull 1360 watts and run cool

https://i.imgur.com/CB8Phmg.png

Note to mods this is not about  L3+  As my goal is to build this with s9i

s9i is cheap  my tests show power and heat can be managed for L3+
the s9i come soon  will show tests for it when it comes.

Sky has inverter/converter power source on order.

If we can  build a solar power source with this in the 1500 watt range doing 5 hours per day in NJ  where 13.7 to 16.7 cent power is common  the source gives 7.5 kwatts a day   that is 1.03  to 1.23  usd a day in power or 375 to  457 usd in power in a year.

The power source should have a long life  no batteries involved
Easy to setup  no grid connection.

the panels rate 20 years
the inverter/converter is 5 or 7 years.

So if we can sell it cheap enough it could work out.

Of course practicalities come in
maybe the ratings are too high .

maybe it does not last the timespan it should 

we won't know till we rest a bit.

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.
