Phase one of the Space Mine is complete: I purchased $43,000 worth of ASIC miners for
the warehouse. I deviated a little bit from my plan; originally, I was going to buy three
L3’s, and S19j Pro and an Antminer L7 - but Chinas Crypto Ban put a bit of the fear in
me and I wanted to order this first batch of equipment with “trade assurance” through
Alibaba so I could get my money back if something didnt work or didnt come at all. Since the
L7 doesnt come out until November, and trade assurance is only valid for 30 days - I would
have had to just trust whatever company Im buying from and Sending Ethereum to a random
company in another country with no guarantees to get that L7 for TWENTY THOUSAND dollars
was a step too far..
So I made up for it by ordering FOUR S19j Pros instead to go with the L3++’s! One
of them has already arrived and that pushed me into phase II of this plan: Infrastructure!
Bitcoin miners, and specifically S19’s are POWER HUNGRY little blockchain hashers. Each
one will drink up 3,100 watts and will require a 200-240v plug. I got four of them, which
means not only am I going to be divvying up over 12,000 watts of power - Ive also got
to mitigate over 12,000 watts of HEAT they pump out after validating all of your transactions
your welcome. I thought that because all of the breakers
in my warehouse electrical panel added up to 300amps that I had that much power available
to me. I was wrong; I made my way over to the main breaker at the front of this facility
to find a disappointing 100amp fuse at the start of the line. Luckily these DO run at
240v so that means I top out at 19,200 watts if Im observing the 80% load rule, so I have
room for expansion.. And.. you know.. Like.. lights, internet, a microwave, mini fridge
and whatever other comforts one tends to enjoy at their office. Im sure a panel upgrade is
in the not too distant future. But first comes dealing with all of this heat!
What I’ve come up with is an 8 foot by 8 foot room built into the back of the warehouse
around the rear door. I was trying to think of a way to dump heat without having to cut
a giant hole in the side of the building - I imagine the building owner wont be on board
with that. So what I came up with was a trip to the Home Depot to buy a replacement steel
door for my rear door - then I cut a giant hole in said door and fitted a 4500 CFM exhaust
fan and bolted it right into the center of that door. Whenever I move out, Ill just put
the original door back on its hinges and itll be like nothing ever happened!
Then I framed up a cube shaped room, and in the wall opposite the big fan door, I cut
out three holes slightly smaller than a 20x24in AC filter, so that all the air that gets sucked
in there will first, be filtered, then pass through the mine and out the exhaust port!
I picked up a couple bottles of expanding foam and some gorilla tape, and sealed that
thing up, and now the hurricane room is complete. An 8*8*8 room is 512 square feet, some quick
math has that fan completely replacing the air in that space every 6 seconds or so, which
SHOULD mean that there will always be cool side and a hot side of this little room, and
these things should stay well within operating temperature, while breathing only freshly
filtered warehouse air. mmmm the best air. I built a simple little slot so I can swap
out the air filters very easily, however often they get dirty. Which I guess will change
depending on how much activity I have going on in the warehouse in general.
CURRENTLY Im all set on electrical, but Im already using every outlet I have available,
which was a Smorgasbord of L6 20r, L6-30r, a 6-50p big boy and a 4 blade L14-20.. The
people who had this place before me sure had a variety of plug needs.. And I got a new
education on 208-240 volt power adapters. I think this weekend Im going to take a stab
at putting in my own line from the panel, so I dont have to run this 75 foot l6-30p
extension cable to the hurricane room. The profitability changes day to day, but
I think itll be a nice thing to look back at a few years from now, to see what these
fellas are earning. So, until next week when the rest of my equipment arrives, right now
I have one S19j Pro, one L3+ and five RTX 3080 GPUs running, which are earning a total
of $73 per day. And with three MORE S19’s and 2 more L3’s in the mail and on the way,
we can extrapolate that to 181 dollars per day, 5450 dollars per month or 65,400 annually
that I should be pulling in from my Mine/Farm as of Monday evening (mind explosion).
Of COURSE those numbers wont stay the same for an entire year. Difficulty will go up,
which makes them earn less, but the price of Bitcoin and Ether could easily go up along
with it, which can make them earn more! (I mine Litecoin and Doge with the L3’s but
Im converting it to Bitcoin because of fear..)
This is the new Space Design Mine. It needs some decoration, and I will give it some.
Ive actually put up a piece of land I own in Central Florida for sale to pay for these
machines so that that money is pure profit, as well as some electrical upgrades so that
I can push this thing into six figure territory if I can find a reliable place to keep buying
machines.
Its funny because even though this is going to earn about as much as working a full time
job, I can only house it for as long as I DONT quit my job, part of which gives me this
amazing warehouse - theres a funny little catch 22, if youre into that sort of thing.
