not your keys, not your coins!

I had a thought for how you can mine using more normal power. Instead of trying to do transaction validation type mining, you can provide service mining. I use this term because when you do service mining, you are providing a service like network or storage. You could run a storage node which pays you coins. For example a Filecoin server does mining, just not transaction validation mining. Those servers run more on 120v and would be less heat / electricity. Just an idea (I am looking into this as well).

As for my test lab, it got moved out to the garage. Its running off a 100amp panel circuit run to a distribution box with 2 50 amp breakers. From there it is going to run to 2 60 amp metered PDU, so I can gauge load per PDU and overall. So far I have 3 running at 26 amps continuous. Will bring more up later this week.

Filecoin 'mining' is not 'Bitcoin mining' though and we would need to discuss on another topic outside 'Bitcoin' subforum.

But sure, there are other ways to mine that are better suited for home use. While I'm all pro-Bitcoin myself, for small-scale home operations I see GPU mining as a quite profitable and viable option, since the larger fans are quieter. If / when the shitcoins you mine (and instantly convert to BTC) with your rig plummet in value and get no longer profitable, you can still use the GPUs for other things, thus they keep a quite high resale value even in a crypto bear market.

I should mention nowadays home miners (pod- and stick-style) from Futurebit and GekkoScience start to be a thing again, but they're less profitable than a GPU rig; though they directly provide hashpower to the Bitcoin network, which a GPU rig can't accomplish.

I literally talked to my electrician yesterday about expanding my home test lab environment and he indicated it would be something like 280amps.... And I started blowing my 30amp circuit with just 2 miners (A10 and a S19J 100). So do that math repeatedly, triple check.

If the circuits in the home were built for 30amp then you're going to need a lot of rewiring to get 280 amps, I doubt you have more than 4 mmp for those from the start, and trying to draw 50kw on them?

However, you MAY have higher powered connection. The point is, check your electricity bill and see the tariff. As far as 3phase is concerned, you don't always need that for a single S17 to run. Just connect the miner to a MCB with atleast 16A freely usable for the miner.

If he lives in a block of flats there is little he can do, for sure it's not a case "higher powered connection", he will have to settle for what the wiring from his apartment to the main circuit is, and you won't see huge numbers there, the best I've seen is 80 and this in new flats that were built taking into account all the stuff people use nowadays. My old flat where I lived was built in the '70s had just 30, and it was always a rule not to start the vacuum cleaner went the washing machine was on.

Who pays how much for electricity?

Just google 'cost of electricity' including what country/state/county/province/etc you care about. You'll get far better information vs comments from random people who could be living anywhere on the planet.

As I understand, the usual domestic connection has a 3kw max connected load and wirings are usually done based on that (240v). So if you already have high powered equipment like geyser, AC, Waterpumps etc, your MCCB/MCB may not take the extra load and may tripp.

However, based on the noise and heat produced I don't recommend running it it at home. You may make some money but you may have to explain a few things every now and then ;-)

The voltage is fine.
Question is, how many amps can be supplied? Each miner pulls around 3.3kw which if fed 230v means it pulls 14.35 amps.
Then there is the noise and heat produced. All that power is turned into heat and the fans used to remove it from the miner sound on par with a large industrial vacuum cleaner.

You really want that in an apartment with you?

I second this! Or my wife does. I first did a bad by miscalculating the amps. Watt / Volt = Amp. You are probably 240v so make sure you know where you can plug it in and make sure you have the right cable. I don't know how many cables I bought that were wrong (I have a pile of them now).

Don't underestimate the beast you are creating. Noise (70 - 80 db), heat (72C or hotter) and location. I put mine in the laundry room so I can close the door but the miners run hot and my wife tolerates me running 2 in the house right now... But am rapidly working to relocate them to the garage given the strains it causes. Shocked

Most miners use 1P 220-240v. no 3P needed unless you start getting into immersion cooling.

thanks all for the valuable feedback. I didn't really think it would be that loud to be honest. I get the Idea now.

If he runs the standard firmware he will only do 2kw, if he runs on low speed below 1.5kw.
Of course, he could try running them at over 3kwh and reach 75TH/s but even without that he would have to go out and in of that apartment only during the night as his neighbors might end his mining adventure prematurely.

Probably he has at max 50 or 60 A, I don't see apartments there getting more, but still, even two of those things screeching all night long in the next room would drive me insane.

the s17 pro can be set to low speed using under 1500 watts and run quietly.

the low setting does 42th

Hello all,

planning to start mining from my apartment. All set to order the equipment from alibaba. My major concern is on setting up the electrical connection. Based out of India with 230-240volts connection. How many S17pro can I run without doing major alteration to my electrical circuit. I can't get 3 phase, only single phase connection. Any help would be appreciated.

thanks
Satish
