Browsing by means of the online again in October, I stumbled upon an odd however genuinely fascinating contraption: a Russian cryptocurrency miner that leverages the warmth it generates from stacking Ethereum to maintain your room heat.

Shortly after I wrote about this uncommon system, Comino – the Russian-based startup behind this invention – reached out to us and kindly supplied to ship one in every of its miners for us to check this winter. We gladly took them up on their provide, and a few weeks later, the Comino was already put in at our cozy workplace in Amsterdam.

After working the crypto-heater for a bit over a month now, we’re lastly able to share our expertise with the system. However earlier than we get to the precise efficiency, let’s get the technicalities out of the best way.

Decided to ship the system in optimum situation, Comino co-founder Evgeny Vlasov flew in straight from Moscow to Amsterdam, alongside along with his enterprise accomplice Anatoliy Knyazev (to not be mistaken with the eponymous DC Comics villain KGBeast).

The duo swiftly arrange the crypto-heater and proceeded to provide us a run-down on the know-how that powers the machine.

Vlasov and Knyazev first got here with the concept for Comino after they noticed a possibility to bridge the technological hole within the bludgeoning cryptocurrency market by bringing a mining resolution that even crypto-rookies can put to make use of.

As such, the Comino is among the many first miners particularly aimed toward common customers – and never strictly hardcore crypto-enthusiasts.

“It’s an overused assertion nowadays, however we wish to be the Apple of crypto-miners,” Knyazev advised TNW. “We wish to make a product that’s straightforward for everybody to make use of. Ideally, you received’t even must learn by means of the documentation, you simply plug it in and it begins working.”


Having stated that, Comino, which runs a custom-made model of Ubuntu, can simply be modified for duties apart from mining. Certainly, Vlasov advised us Comino typically will get enqiuiries from researchers, concerned with high-intensity computing duties, who’re occupied with re-purposing the machine for different makes use of.

The rationale for that’s not strictly the elements housed inside its metallic case, however its environment friendly and durable construct high quality. Vlasov and Knyazev too are first to confess that the actual worth in Comino – so far as hardware goes no less than – is within the proprietary elements that join all of the GPUs packed contained in the crypto-miner.

As Vlasov explains, not like home-made miners, which are usually quite cumbersome in dimension and sometimes make very loud noises, the Comino was designed to be far more discrete and accommodating. It was additionally outfitted with proprietary water-cooling system that Vlasov and Knyazev declare will hold the machine alive for years – a lifespan for much longer than that of most home-made mining rigs.

Comino’s web site claims a most noise stage of round 30 decibels, and whereas I’m no noise knowledgeable, the overview unit we examined was fairly silent – a lot quieter than an precise fan-heater.

The truth is, the noise is so low that at one level Knyazev worryingly misidentified the sound from the little fish aquarium we now have in our workplace with that of the Comino. Certainly, the crypto-heater is much less noisy than an aquarium.

Listed below are a pair movies that will provide you with a greater thought in regards to the cacophony home-built miners trigger:

Along with its proprietary water-cooling system, the system additionally comes with a slew of custom-made elements – like cables, connectors and risers – to make sure the longevity of the system.

The rationale Comino opted to supply their very own risers was as a result of trade options couldn’t provide the identical resistance to high-intensity indicators and waves that mining rigs need to cope with. Vlasov estimates that the compendium of little touches like these should hold the miner up-and-running for no less than 5 to 10 years.

So far as the remainder of the innards go, the Comino N1 (the mannequin we had an opportunity to check) boasts eight ASUS P106-100 6G graphic playing cards mounted on an ASUS PRIME Z270-A Motherboard, in addition to three NOCTUA NF-A14 PPC-2000 PWM followers, a custom-made Black Ice NEMESIS GTX420 radiator and a couple of Chieftech PROTON BDF-750C 750W energy provide items.

All of this oomph quantities to about 1kW of energy consumption per hour. Ensure that to test your native electrical energy charges to get an thought of how a lot that may add as much as your power payments.

The contraption stands 63.5cm tall, with a size of 45.9cm and a width of17.5cm, which implies you would simply match it in an idle nook of your room and overlook about it, whereas it does the mining for you. And that is exactly what we did.

As soon as we put in the mining rig in our workplace, which virtually included connecting the crypto-heater to the web through the web-based dashboard system developed by Comino, it robotically created a pockets and commenced mining Ethereum. As straightforward as this.

After all, if you have already got a pockets, you continue to have the choice to attach it to the dashboard. You may as well join every other mining rig to the Comino dashboard, in case you wish to comply with your entire mining efforts in a single place.

Amongst different issues, the web dashboard exhibits various statistics the Comino builders had programmed to watch, together with the present and common hashrate at which the miner is fixing cryptographic puzzles, the present and common temperature at which it operates, in addition to the unpaid steadiness of Ethereum you’ve accrued. It additionally exhibits stats for the temperature of every separate GPU.

Since putting in the miner on November 16, it has thus far transferred a complete of little over 1.2 ETH to my designated pockets – this equals to roughly 1 ETH monthly. On the time of writing, my mining returns quantity to about $814, in response to CoinGecko.

The way in which the system is set-up, the miner will switch the Ethereum to a pockets of your selection anytime it has mined no less than zero.2 ETH.

As you may observe within the screenshots beneath, the Comino N1 maintains a mean hashrate of about 200 MH/s, and a mean temperature of roughly 60C (±140F) levels .

Whereas a few of this information is seen on the system’s built-in LCD indicator, chances are high you’ll discover your self partaking with the web dashboard far more typically than with the precise miner – and that is really how Vlasov and Knyazev think about issues.

Apart from a one-off exception to reboot the miner, following a glitch within the LCD show (which had no impact on the precise mining), I hardly needed to work together with the machine; and this can be a good factor, particularly for somebody who desires to stack on crypto with out having to fret about technical points.

All through this one-month trial, the one concern I skilled with the miner was that – for some cause – its ambient temperature sensor inaccurately picked up the temperature of the GPUs inside (which had simply taken a break from mining); this prevented the system from booting up once more, till it cooled down a bit.

However apart from that, it ran as clean as butter. After reporting this minor malfunction to Vlasov, he advised us their group is trying into implementing an answer that may enable the machine to activate, however will solely let it mine as soon as it has cooled all the way down to a extra appropriate temperature.

At $5,000 a chunk (at the moment discounted all the way down to $four,500), the Comino miner is definitely not low cost, however when you’re searching for a straightforward solution to get began with mining cryptocurrency, it undoubtedly does the job.

In all equity, you may most likely construct a less expensive mining rig, however Vlasov and Knyazev are skeptical in regards to the lasting endurance of leisure mining rigs. After all, if neither of those choices attraction to you, you may all the time match your personal crypto-miner within the trunk of your Tesla – like this man got down to do.

And in case you have been questioning about how dependable the Comino was as a heater : it definitely saved the temperature excessive sufficient to avoid wasting power on heating payments, however not sufficient to make you activate the air conditioner. Which is strictly what you need from a a machine that was constructed to financial institution on crypto.
