I think it pays for itself in 24 months if you consider the electric bill as if it where a regular space heater cost.

Something to ponder.

30 months = 900 days x 2.30 usd a day = 1860  so if you need to use a space heater 24/7/365

it pays off in 30 months.  if you need it ½ the year it takes 60 months.

not counting  diff and coin price.
Heh - not a chance in hell any miner like this would still be making money in 30 months from now.

If your goal is to just make money, then there's plenty of altcoins to be mined with way lower difficulty (and payoff) than BTC.

It's a bit altcoin territory but you can always point your miner to cheaper coins that pay less for lower hashes, proportionally...

This would have been good gear if they released in in Dec 2019 they did not.

I do not understand why you woke the thread up ⬆️ to post your comments as they do not seem to belong.

I never saw any of these mining ⛏ anywhere on the net.

I offered to review it.

Standard terms.

If you want btc  send the gear upfront.

If I like it I will  buy it.

If I don't I will send it anywhere you want.

If you want upfront payment I would only send paypal.

They never really got back to me. So I let it be.

From what I understand :
It is a space heater that mines .
It is not a miner that  is a space heater.
So if you need a space heater it has value.
If you do not need a space heater don't buy it.

Big plus

1)  you can mine to an address and hodl the coins for a few years.
2)  if you use a space heater at work  this should be good for you.

so I see you use this psu.

https://www.trcelectronics.com/ecomm/pdf/lrs150.pdf

that is a meanwell lrs-150-12

159mm by 97mm by 30mm

it is 87% efficient

I used many meanwell psu's

IIRC  they have a 91% efficient model

The Hrp is 88% at 12 volts same size
https://www.trcelectronics.com/ecomm/pdf/hrp150.pdf

I need to do more research.  But I do like meanwell psu's as they are easy to source.

I received a PM from them on the 20th. I had to use google translate though and I believe they are ready to ship out demo/test units maybe. I did respond when I was home but it wasn't until the 24th. I haven't heard back. I filled out a form for them a couple months back as I'm interested in seeing the unit in action, and giving it a review. Mild winter so far but this would go nicely near the wife's work space which is a cold spot for sure.

I hope you get one and let us know all about it.

I am also still waiting for news on this I wondered if they may be looking to build a more powerful version in future.
Have been watching the videos on youtube but they are mostly in RU I do think mining chips in smart devices is going be become such a think not only for bitcoin but many of the alt's.

I would say it might be a good idea to make some videos in English as the translation is not so good on youtube and I was quite keen  to know more about this one.

A meeting with the RMC project (Russian Mining Center) was successfully held in Moscow and agreed on future cooperation with Dmitry Marinichev.





Alexander Shulgin, organizer of conference in Irkutsk, Russia, also liked Smart-Convector. In his turn, Alexander recommended to patent the smart-convector solution.

As interested as I am in this concept I do have two main concerns.  Firstly, how fire proof are these units? Secondly, how healthy is the air coming through these things? Any carcinogens tagging along with the heat pouring off this thing?  Those are the two main reasons I run my Innosilicon T2T 30T in my shed (that and because it's way too freaking loud to run it in my house).

well 8 th and 500 watts = pretty good but what is the price 1800 usd?  and does it ship from Ukraine or Russia?  If it is not from  China  no Trump tax.

hmm maybe Putin does own Trump (A joke please do not think I am attacking anyone).

I have owned tested and played  with :

A841
A851
A921
A1041 ------------  this is pretty good as a space heater if you have the bigger psu that is not mounted
S9
S9i ---------------- my 1 board mod  is good
S9j
S15
S17pro
T15
T17
M3
M10 -------------- decent on low power
M21s ------------- decent on low power
M20s
inno t2 t24
inno t3 t39
inno t3 t50

I could most likely match or just beat the efficiency and get 14th  with a 2 board m10 set to low speed this would cost less then the model here.

my s9i 1 board mod is quiet  but  neither the s9i or a modded m10  would be as quiet as this build.

If you really need a space heater this item could be okay.  I am looking forward to seeing them in the field.

I would test and demo one  but I do not think I would buy one.  So if I did a test/demo  I would ship it to  the op once the demo is over.

Hello! We are on the air ... Smiley A recent roundup of the project's work:
1) Participated in the conference in Irkutsk, Russia on August 8. There was a presentation of Smart Convector, and Mining 3.0 concept.
2) We developed a technical specification for Smart convectors production in Ukraine, a passport for equipment, and started registering a certificate of conformity with Ukrstandard.
3) We decided to make a test batch of 50 pcs. smart batteries and 30 pcs. smart mini. Estimated date is November 15-29.
We said earlier that we will go to crowdfunding indigogo in the end of 2019 summer, but plans have changed to the above. Who wants to take part in product testing - write to us!

P.S. We are preparing a translation of the video into English with the results of the convector test for 27 days! Smiley

And we are back to the R4 design. Might as well pick those while they still exist...

Or someone design a case that takes two or one S9 hash boards with a scroll fan.

The R4 was actually like two S9 hash boards, but the boards are physically different (wider).

Perhaps something interesting could also be done with the newer MicroBTs or Ebangs, using a single board.

I actually did this combining salvage parts from an R4 and S9s. The controller was somewhat compatible but the R4 I had was finicky. It did cool it but the arrangement of the heatsincs and the shape of the s9 boards just didn't like how the r4 was shaped.

It did work out of the case and severely underclocked with a few angles but the R4 blades fit just so. I'll eventually post on the quieter S9 fan stuff I'm working on if I can get it to look nicer.

>~<

Yeah - the Franken-appearance turns most away - I just want it to work.. but a nice finish does it well.

These projects, given enough money and engineering and .. phew. These are the projects of the future. Maybe. Tomorrow. Someday.

An S9 Running a single board or two with a fan bypass modification + scroll fan will be much quieter and achieve relatively quiet-ish heating performance with better output range than an ambient radiator would achieve.
But of course it would be hard to market that as a "space heater" in all of it's hacked-together appearance and what not.
I like these projects but would prefer a stronger hash rate.

Don't use an S9 ...

Avalon a841 is okay it can do 90 watts a th.

The s7ln was very good. Of course they are too power hungry. 250 watts.

Side hack has the r606 it can do 1th at 110 watts it is pretty quiet.

The op’s gear is most likely better 60-65 watts a th and quiet with nice physical design.

If this was at the 900 dollar price point it would sell well.
At 1800 and not in stock so to speak it is difficult to get traction.

An S9 with both LPM and ELPM enabled is way too loud for a living room. I cannot even begin to imagine the 4 fan monster (plus 3 little ones on the psu) of an S17.

Maybe, just maybe, running Braiins OS, where you could force very low speeds and voltages, but thats only available for S9s and T1s.

Canaan was a bit ahead of its time, but the idea of appliance mining is good. Someday, all mining will become too expensive to do on large industrial fans, only hobbyists willing to spend money to keep it running and those with free energy will remain, In that world, all those little mining appliances can easily become the main mining force.

As with this heater, you can look at it as a heater that helps itself pay its power bill. Same with the Wifi or the TV, perhaps ovens and kitchens could come next, water heating, etc.
Or just run a recent miner in low power mode that also allows you to adjust the fan speed to keep it quiet enough.
Like I've been doing for years and even some I've told about it have created a thread about it.

What I was referring to would be the ability to control the modes ourselves. You indicated in the next quote that the machine essentially self tunes itself based on the room temperature. I am a person who runs a bank of 741's in the winter to heat my home, I like being able to overclock them in the coldest months and in fall/spring play with the settings to adjust the heating to my needs. So my suggestion is to save money and put out an inefficient miner, making it an efficient heater. The product pitch should be "The heater that pays", as that's what's being produced.

My reasoning here is that it should be more cost effective to use older/obsolete chips when compared to current gen gear. This can help get the cost of the product down to the point where it makes sense to someone to pick a few of these up. I also wouldn't launch it with multiple colors available for your first run, it has to be cheaper to buy all 1 color as opposed to being able to offer 3. If the product does catch a market share and gain adoption for heating future models could have a color option, but for now I'd say the obstacle is getting the cost down for people.

Crowdfunding is a good idea to get the capital needed for a launch. I don't follow it much but it's generally seen as more of a donation to inventors to help them get a prototype together or finance the first run of a product. Usually there are some "gifts" involved, or the opportunity to buy the product at discounted rate, or just the opportunity to buy first.

Best of luck to you with the project. Like I said before I like the project, I was excited when I saw Canaan putting a similar product together. They ultimately decided it wasn't viable outside China. Hopefully you can find the right group to buy these.

In a few words about the modes of operation of the convector:
if the room is hot, it adapts for minimum power consumption and efficient mining. If it is cold in the room, it is more warm and more THs.

At the expense of crowdfunding - we will provide a good discount on the first 100 devices, as well as 3 colors to choose from, opening a representative office, as well as just support for the project, also heater for one module on a scale of 1: 5 to the Hotmine CM-1 - 100 W, 1.6+ THs, lowest price.



[...]

There is a problem in that a limited number of convectors can be made on old chips, old chips are no longer produced, and new ones are no more expensive than old ones. And older chips will most likely have significantly worse performance (performance-efficiency)

In this thread, we are discuss ASIC chips, not gpu.



In September 2018, cryptocurrency hardware manufacturer Canaan announced a novel product-a mining heater. According to official specifications: the product with the model name A851H, has a hash speed of 14.5TH/S@1450w/h, the efficiency ratio is 100w/T and it integrates 104 A3210M chips of 16nm.

I get the whole space heater that mines, but who would spend that much on a space heater!

Not me and I have a place that uses a space heater 9 to 10 months each year. As I said I use three PCs each one has two 1080tis that have been paid off they use about 800-900 watts and are pretty quiet as I run them with low clocks.

This is the problem with this gear if marketed as a heater that mines it is 1800 which is too costly.

They are better off with s9 chips clocked to 80 watts .

The s9 clocked to freq 475 at 8 volts would do 540 watts and 7th

design a two board case like the older s7 ln and it would be under 500:bucks vs 1800

Heh - not a chance in hell any miner like this would still be making money in 30 months from now.

it is a space heater that mines
not a miner that heats.
If treated that way it always earns money..Since you only use it when you heat or need heat.

If you consider it to be a miner that heats you do not want it.

If you read the example I gave of my friends office he could use it.

He does not control the heat
He does not control the ac

His place is too cold from lack of heat 5 or 6 months every year.
It is also too cold for 4 to 5 months from too much ac every year.

so for 9-11 months every year he used to use this

note image is from amazon of a delongi space heater:



he would set it to 600 or 1000 watts and run it for 9 to 11 months a year.  so 9 months is 9 x 720 = about 6500 kwatts lets round down to 6000 kwatts spent on wasted heat every year

if he spends 6000 kwatts on this gear none of that counts as power cost.

so that gear would be earning money in every year it works for the first 6000 kwatts it uses.

Do I think it is worth buying at 1800 no I don't I think I can build a quieter miner cheaper that cost less.

Since my friends off basically has 6000 kwatts of power for me to burn each year  I have been doing it for years. (2014-2019)

I think it pays for itself in 24 months if you consider the electric bill as if it where a regular space heater cost.

Something to ponder.

30 months = 900 days x 2.30 usd a day = 1860  so if you need to use a space heater 24/7/365

it pays off in 30 months.  if you need it ½ the year it takes 60 months.

not counting  diff and coin price.

Maybe they are trying to raise the production quantity and thus reduce the price per unit?

I've seen a lot of companies on Kickstarter do that. They will establish levels and perks for each level of funding/purchase, they range from just a thank you to extra features or discounts based on quantity.

It really is a neat idea, just way too expensive for most residential elec rates.

Yes, in the most energy efficient mode, it shows 8 THs/500 W now. 900W/11TH - in maximum mode. Modes depend on external conditions (temperature), Hotmine CM-1 himself adapts to them Smiley Smart guy...)

40 db - it is veryquiet noise, like noise from a laptop at low revs. It seems that there is a movement inside, and a sensitive sound meter can hear this noise.

Yes, it is psu, but without fans, passively cooled.

price seems high but maybe i read translation wrong.

62 watts a th is okay for a quiet space heater.

Well it appears to produce the same 8 TH than the R4, but at what wattage, 500w?

Passive cooling sounds interesting, where does the 40db come from? Its psu?

15Kg is like 3 times heavier than the R4 Smiley

Price is, a bit expensive, but so was the R4. At this point in time spending the same amount for 8 THs i'm not sure its worth. You could take something like a damaged S17/S15 with just two or one working boards and achieve the same or better.

Don't get me wrong, silent miners are important, i welcome this addition. Would love to see something with MicroBT or Bitmain newer chips...

3 of them do 1500 watts or about 5100 btu  it would be costly  and the 5 month usage makes them not "free" all year round

Yes sir! Gpu of 210 Mh/s / 1000 W equal to $1.90 per day taking into account the cost of electricity and these would be okay for the right person
   
It is also be okay for the right person from bitcoin/ASIC community to use Hotmine CM-1 and make $1.65/day depends of btc cost, taking into account the cost of electricity, quietly heating space.

Well  lets say  you use a space heater all year round.  I actually do know of a few office spaces that do.  As they have no control over the ac or the heat.

And they have too much ac in the summer

and they have too much heat in the winter.

I have 3  2gpu  card pc's mining in an office like this.  this pc's use 1080ti's and were purchased in 2017.

They do 330 watts each and are quiet to build something close right now I would need to spend  3600  which is equal to 2 of these units.

both use 1000 watts.  16th is about  $4.30 a day  since I would already use a space heater  that is all profit.

my gpus make about the same $4 a day.. So if you are a very specific user of space heaters the gear almost makes some sense.

4.30 a day x 900 days = 3870  just a little cheaper  and these would be okay for the right person.  A person that uses a space heater 24/7/365.

I read this in the morning and didn't follow to the website. I like it overall it's a neat silent heat option for an office space or something. A larger design with the ability to heat rooms would be neat to see. The price is a killer for most though like Phil mentioned - 1800 USD is what I assume it was saying.

When it comes to being a heater - the efficiency doesn't really matter. Keeping the noise down is the biggest concern. A power hungry beast just allows more heat into the room, if you can downclock it through settings then it can be tweaked to comfort. That's they type of model I would want to see, a 5 month heater (depending on location) with the added benefit of mining BTC.

What are you specifically interested in? Would you like to see how it heats up and heats the room?

As for price, yes it is a killer, but for this moment R&D plus hardware the price cannot be lower than $1 800...  So a good mood and a batch for the production of 1000 convectors guarantees the cost of Hotmine CM-1 at $1 600, and for the batch of 10 000 convectors - $1 400.

We will try to display the convector as much as possible in the work: the room temperature, the warm-up rate of the device, as well as the room heating in the next video on our YouTube channel. A link to the video will also be published in this thread.

price seems high but maybe i read translation wrong.

62 watts a th is okay for a quiet space heater.

Here we will make the most accurate review of the product Hotmine CM-1. Silent and useful miner to Bring an In-Home.

Features:

In this development there is a power supply with passive cooling, as well as specially designed radiators, which also passively remove heat from the chips.

1. The heater, equipped with 165 14nm Clarke chips and 15 control chips BF180, delivering a hashrate of 8TH/S with power consumption at 60 W/THs. 8 THs/600W or 72W / 1THs (given the efficiency of power supplies). This is the most energy efficient mode.
2. The noise level of 36 dB is not higher than fans or air conditioners in your apartment.




3. Height x Width x Length 450 x 100 x 1200mm
4. Operating temperature 85 °C (for Clarke chips, the optimal temperature is 85 °C - it produces the best energy efficiency). Operating conditions 0 °C - 30 °C. Max working t °C - 65 °C

Photos from the thermal imager, which shows the temperature of the convector case from different sides, as well as boards with chips installed inside:



5. Weight 15 kg
6. Simple and minimal design. Production in 3 colors is planned: white, gray, black.
7. Network connection: WiFi
8. Self-developed control panel:



9. Own design of boards based on Clarke chips.
10. Own design and own (ukrainian) production of case and radiators.
11. Silent Convector heats about 10 square meters of space.




"This has potential of being a robust new generation miner for the same kind of user group as the Antminer R4 users.
And a great device for heating instead of a normal electric conventional heater".


What else is needed? Smiley A quiet miner that effectively heats your home and also earns some bitcoins.
