@selo will you give us a heads up as to when going public in Indiegogo?

Yes, sure  Wink

+1 on that, I'm very interested in this product for half the price mentioned above.

Nice that's a good time to have some products available for launch. I'll reach out this weekend but as I'm entering my cold season I would be interested in seeing one of these in action.

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.

my s9  mods work well at  88 watts a th  on lowest setting of 3300gh and 95 watts a th on setting of 4700 gh

I do 35 db on lowest

I do 47-48 db on higher setting.

but they look like an s9 not pretty at all.

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.

Exactly - most of the major brands have released Low Power Mode or Low Power Enhanced mode or something like that.

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

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

Modes depend on external conditions (temperature), Hotmine CM-1 himself adapts to them Smiley Smart guy...)

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)
