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? A quiet miner that effectively heats your home and also earns some bitcoins.

Early followers of this device, thanks for your support! We are waiting for your questions here and in Telegram. Also we are open to collaboration and ideas.

Hotmine CM-1 is the code name of our product 

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?

We warmed the room - now we warm the corridor 





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

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.

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

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

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

 

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

Hi! Check our R&D Here is Big One Usb Hub as a one module from our convector-miner product, but not about that now.

So the one module can still heat the room without noise! Also it's our test 33 Clarke-chips USB sticker.

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

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

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 everyone! Today we made a calculation of the Convector's mining profitability in different modes. We took two electricity prices as a basis: $0.05 and $0.1. We suggest you familiarize yourself with the calculations 


Option №1
Electricity cost - $0.05

Maximum Convector Operation Mode, 11 TH / 900W
1) daily income - $2.15
2) consumption per day - $1.08
3) daily profit - $1.07

Optimum Convector Mode, 8 TH / 600W
1) daily income - $1.56
2) consumption per day - $0.72
3) daily profit - $0.84

Minimum Convector Operation, 9 TH / 550W
1) daily income - $1.76
2) consumption per day - $0.66
3) daily profit - $1.10


Option №2
Electricity cost - $0.1

Maximum Convector Operation Mode, 11 TH / 900W
1) daily income - $2.15
2) consumption per day - $2.16
3) daily profit - "-$0.01"

Optimum Convector Mode, 8 TH / 600W
1) daily income - $1.56
2) consumption per day - $1.44
3) daily profit - $0.12

Minimum Convector Operation, 9 TH / 550W
1) daily income - $1.76
2) consumption per day - $1.32
3) daily profit - $0.44

Do you think it is better to transfer this branch to the "hardware/mining" board? Will it increase the views or is it better to leave as it is in "project development" board?

Hi there! 

Yesterday we connected a mini-computer and a control board to a board with chips of previous development - U6. We did this in order to test the operating states of the indicator lights in a running mining process. New boards based on Clarke chips are in production, but will come to us in a month at best.

Also yesterday we tested the control board of the miner, where the settings take place, and also the states of the convector miner is displayed.

The photo shows a translucent white window, under it will be lights. Also we embedded a power button:


Control panel:


Convector's working conditions, on the left blue lights on the video: https://youtu.be/nLWmbqwKE94
The next step is to connect all the led's on the one board. And it will remain to build led's under a translucent window.
