The Hotmine Convector-Miner. Development on the Clarke ASIC chips

[selo]

Ok,
So did I understand it correctly?

With 0.05 cent electricity price,
if household heating benefit is not taken into account,
it will take roughly 1800 days to make even,
if the numbers stay the same and if the miner retail price is 1.8k USD.

Yes, it is sounds correctly. That's why it is a convector, that will compensate for the same cost of "consumption per day". Thereby, several times faster returning the cost of equipment.

Hi there! We are looking for partners for certification of a miner in Europe. Maybe there are such people in our community?

Thats an interesting project, is it possible to implement such thing in a place with high humidity?

High humidity is very bad for electronics, especially if it will turn off periodically.
Working humidity for convector is 20~90% RH non-condensing.
For increased humidity conditions you can look at the boiler-pump WX12 on our website or use Fancoil

Finally We received boards with 33 Clarke chips from production, delivery was delayed. We started testing boards with chips, as well as installing them on a convector with subsequent optimization

Wow, those are nice and big heat sinks you guys have.

After setting up the software for the new board, as well as activating all the chips on the board after a brief test (30 minutes):
 - the temperature of the radiator (one of three temperature sensors) reached 82 * C
 - the planned current 9A;
 - the voltage on the power supply unit 11.9V;
 - mining from the entire module 1.68 TH (33 chips) = 51 GH / sc on a single chip.
Temperature and current to keep steadily.

We went clearly to the planned characteristics of the basic (minimum) operating mode of the convector.

For an hour of work - everything is stable.

The board gives 1.7 TH, one chip gives 51.6 GH, consumes 104.4 W

After a series of successful tests and settings. We installed the Clarke boards on radiators and fixed them in the convector case.

The convector is running!



Everything is working. Watching. 62 W/TH - one of the best efficiencies obtained 8.26 THs / 515 W
There are questions about modes programming on the way

This is a very cool project I recall hot-mine from a few years back whatever happened with them?
Last I saw they were building some kind of boiler system with the chips is that project now finished or is this the next stage of development?

I look forward to reading more about this and keep up the good work.

Thank you! Hotmine have been working continuously since 2013, we just have not publicly covered our development so actively. Do you mean a boiler for heating a house? Yes, the development has been completed and now the boilers are actively working, heating houses. More information can be found on our website: https://hotmine.io/ru/catalog/5. So to say, there is a product, but sales have not gone.

And about the Convector Miner - this is our current development on new chips.

We warmed the room - now we warm the corridor 





Also check this one gif! What do you think it is?

Cool,
the LEDs in the miner modules make a nice night time show

Yes, it is LEDs night dance))
What do you think, is it necessary to introduce the mode of operation of the convector so that there are no light effects from the LEDs?

Hotmine CM-1 is the code name of our product 

[HagssFIN]

I don't mind the led show,
but maybe there could be a 'dark mode' as an option.
