Return to Russia to startup production of CoolTank 2.0. Enjoyed Russian nature and nice weather. See some pictures.

Cardano is a proof-of-stake blockchain platform: the first to be founded on peer-reviewed research and developed through evidence-based methods. It combines pioneering technologies to provide unparalleled security and sustainability to decentralized applications, systems, and societies. WHAT IS A STAKE? Ada held on the Cardano network represents a stake in the network, with the size of the stake proportional to the amount of ada held. The ability to delegate or pledge a stake

This Saturday I am moving the container with CoolTank to a new location. #CoolTank #relocation

All available miners on the market are made for air cooling; therefore, hashing boards are equipped with huge amount of heatsinks, i.e. Antminers S9 has heatsinks on both sides of each on three hashing boards. As Immersion cooling fluid is very expensive thus there’s the challenging to maximize the number of hashing chips covered by the fluid level. Antminer S9 hashing board with heatsinks Heatsinks removal process Heatsinks are not required for the immersion cooling process,

Project background I started the project in January 2018 on the Bitcoin mining hype by purchasing a few ASICs from Bitmain. ASICs initially were located in the apartment but shortly were moved to the heat-insulated container with AC connected to industrial electricity in Jebel Ali (MFC). In April 2018, an overheating problem was raised and fixed by airflow management, but in May 2018, serious investments are required into the air cooling system. I had to stop mining until Oct

You can see boiling liquid evaporates, cools down and rain back. The boiling point is 61C. Chips temperature 65C.

In crypto mining profitability of operations heavily depends on difficulty of mining. Difficulty rises and share for each mining machine drops. Share drop affected by new mining farms joining mining and new more effective equipment availability for purchase. Mining operators have to continuously invest in new equipment, approx. every 2 years. So there’re plenty of obsolete miners available for sale on Alibaba.com. You can by Antminer S9 13.5T for 150$. When it was issued to m

It was a long way, but finally we did it! Here is the video: Miners are working inside. There is the first benefit: Antminer S9 13,5T working 15T

Finally I fixed cold trap by changing thermal elements I can proceed the start up process. To be continued…

Hello everyone! We haven’t posted anything for a long time, because of a problem that forced us to invent solutions. Everything was good. We installed everything in the Cool Tank and run last tests before adding liquid freon. We noticed that cold trap temperature raised too high up to 50+C. Why this could happen? Previously we noticed that pump was working a little bit noisy. The reason for noise was air in pipes. While we were fighting with air bubbles removal from water flo

We are running different tests

It’s time to put mining hashing boards to CoolTank

Hello all! Here’s a quick update. We’re finished majority of mechanical works: piping, electric and sensors installation. Now water flow sensor will keeps the pump from dry work and water temperature sensor adjusts speed of the fan on external heat exchanger. What’s next? It’s time to assemble hashing boards together, make wires to connect them to power supply units, install Arduino controller and make final testing before start.

Here is a quick update. Today we started dry cooler installation works. Hopefully tomorrow we can proceed with piping works.

We have been connected to the power supply, so now we can start piping works and dry cooler installation.
