What you guys think of my Bitcoin/Litecoin farm

[UnknownBTC]

So after months on preparation ideas and fails, I'm finally operating right now with 10 S9s (120 TH/s) and 4 L3+(2000MH/s) just to let you guys know it costed me a lot of time ti find a place with with enough power capacity and then it costed me 7000$ for an electrician to do 32 outlets on that room for me. i also bought 2 portable AC/s and a few fans.

so what you guys think?

Nice, but would look even more nice if you cut holes in ceiling boards for ventilation pipes going through.
And some zip ties for cabling.  

Also, I must say that there actually already is a thread for mining rig pics

Thank you i was not aware of that post and i also appreciate the suggestions, I'm planning to do it i initially had it without pipes whatsoever and of course it did not work so i just add those yesterday and wanted to know first if it wont cause any trouble as the A/C unit's conducts go trough the ceiling , is doing good so far i may do it permamnent with some holes as you suggested good idea.

I'd love to hear about the "fails" so we could possibly learn from your mistakes.   I'm interested in starting a small farm like this as well.  (currently, I have only 3 miners, but room for at least 10 more - need power outlets though)   I have plenty of cooling (room temp of 65f/18c) but the chips are still running at 141f/60c - would be interested in your room temps and chip temps?

How does the ducting from the miner exhaust effect their chip temperature?

You are going to lose a healthy portion of your profits to those AC units. Those portable types are the least efficient of all you could have used. You should really work out a better cooling system that doesnt require AC if you want to come close to maximizing profits.

Now that you mention it this is actually very interesting, so in the set up i have 10xS9s running with the pipes to the ceiling and 4xL3+s just with fans there you guys have the status of one of each kind. I don't see a major diffrence but the screens are difreent too.

You should try Canaan 741's for bitcoin mining. They have a shorter ROI and almost as efficient as S9's. Some say they have a lot study hardware than S9's. Might make a huge difference in the long run.

Compare their ROI's yourself:

741's are in a discount btw (714$now), nice hash calculates the ROI by the old price tag -818$.

You're indeed right this is was an out of the rush set up as seems like i need to get a permission for whatever i want to do in there so i just wanted to put the miners to work asap, I'm currently having a engineer design an exhaust system so i can get rid of the portable AC units i also have central air but it just not enough.

Interesting!   Thank you for sharing.   How did you decide to split your machines 10 to BTC and 4 to L3?  (if you had it to do over, would you choose a different ratio?)

Thanks again, your input is very much appreciated.

Of course knowing now the outcome and the fact that it took me a couple months after receiving the machines to put them to work o would have gone ALL IN with the L3+ being those  just a bit more expensive than the S9s and making at least 4 times more, regardless it was the wisest call to split my units between S9s and L3+ so diversifying my farm in case the the Litecoin difficulty would have gone up way too much or the currency would have fell. (which did not happen)

In four season climate, its ok JUST to have air cooling system,
but in tropic area like mine, out door temp almost always in range 30-33 Celcius at day and around 24 at night. AND DUSTY
Without Aircon, only with air circulation, there no hope to have the temp keep down.

Yes, the electric will kill the profit but if you dont the temp will kill the mechine.

That why, i envy for their good weather to set up a farm.

[UnknownBTC]

You need to recoup the $7,000 for the electrician on top of the miner costs, hope your power is cheap/free and/or LTC BTC prices go to the moon  

Is not cheap neither is free (.1 Kw/h) but anyway the way that i see it eventually i gonna brake even also got dash and more L3 miners on the way + this is a learning experience thats gonna give me the knowledge that i need to do a bigger project in the near future. Knowledge is not free at least not this kind i think.

Last add on to the farm!:

Ten cents per KwH? I'd have considered Altcoin mining at that power rate earlier in the year, but Bitcoin is more stable as we've all noticed. Not a bad electrical cost, most people have costs much above that. Knowledge is mostly just electrical work in Bitcoin and a little bit of dirty work, if you plan on getting some kind of large building or factory for mining you'll learn even more You can actually learn a lot about BTC mining without actually having a miner, but for the electrical work, it does help to know a bit and possibly shave some money off of that.

Exactly! i think the most important that i'm learning of this experience is about the property itself the landlords are a pain in the ass they've  been bugging me a lot since i signed the lease of course they want me the get city permission for every step that i want to do i should have done this on a land on a rural area it gotta be the best way that what i'll do in the future

Why do you need to go to the landlord to inform them of what you are doing? The less they know the better IMO

so what you guys think?

Congrats on the setup! Since you asked what we all think, i will solicit my opinion that is based on my own experiences.

The biggest mistake i made when getting into mining was that i did not prepare myself to scale. I started off with just a couple S9's but i did not prepare my area for what eventually turned into an expanding operation. I wasted both time and money because i simply did not plan for ANY expansion whatsoever. If i were you i would reorganize your operation into something neat, organized and scalable. This dramatically reduces troubleshooting time and increases your uptime. I would also suggest learning how to do electrical work yourself as it will dramatically improve your ROI especially considering you have very expensive .10 cent power. Depending on the electrical setup at your location, you should be able to add a breaker, run wire, and attach an outlet pretty easily. After paying $200 an outlet for my first two S9's, that was the FIRST thing that i resolved to learn to do myself and it has saved me thousands by now. I ended up installing a sub panel, breakers, ran all the wires to my PDU outlets, and only paid an electrician to come inspect my work. This ended up costing me $100 for the electrician's time plus $250 in materials instead of the 4k he quoted me to do the work himself. I hope you understand, i am not negatively criticizing you, just trying to provide some input to encourage you as I am sure you will end up outgrowing your current space.

Lastly as i am sure you know, HVAC is a pain... I have learned both through trial and error along with hours of research that the key to keeping the operation running profitably does not necessarily include air conditioning, rather successfully exhausting the hot air out and away from the miners. The biggest and baddest commercial mining operations out there are finding that large traditional monolithic data centers dont work that well for mining because the HVAC infrastructure ends up using up to 30% of the power capacity of the the building. Instead they are focusing on smaller spaces with massive airflow. This quickly gets rid of the exhaust while feeding the miners with a positive flow of clean ambient temperature air. I think where you are located and what the ambient temperatures are plays a big role on how realistic this is for you. Again, congratulations on your setup! I hope you do not interpret my comments negatively, i want to see ALL miners succeed

Don't envy Central Washington this past week (and probably for a few more weeks).

For perspective - there is a hill near my place, top of which is less than a mile away - and the smoke today is so thick I can BARELY see the top of that hill.

If you are venting the heat out....why have the portable A/c units at all?

[UnknownBTC]

Why do you need to go to the landlord to inform them of what you are doing? The less they know the better IMO

These guys are actually very bossy having the equipment sitting in my house for a couple months and watching the ROI to get worse and worse got me into getting in this place recommended by the electrical contractor now after signing a 5 years lease don't ask me why, these guys may randomly enter into my space and check whats up as I haven't come up with all the bullshit they want me to get of the town hall. It is what it is you live and learn i guess.

Hey first of all thank for the comment its very informative what you just told here is true that I could save money by doing the electrical work myself, I'm not sure how this would play a roll on the permission that the landlords are making me get, but even leaving this aside I used to study Telecom engineering back in the days before i dropped out so i do have some electrical knowledge or at least i still remember the basics Do and Don'ts of an electrical circuit but when i put the ROI of these L3+s Miners and Dash miners that are soon to come i find extremely risky and inconvenient  to even think of doing these myself risky because I may cross the wrong wires and either damaging some equipment or leaving the building that i share the rent with my partner which uses it as an office and storage without electricity causing this to make him be piss off and getting even more tired of the noisy enough mining room and the landlords all over my ass again just to think about it give me nightmares maybe in the future when I owe my own land this may be a possibility.

Regarding the A/C I totally agree with you these project was not planned that well form the very beginning so the first though was i have to keep this cold somehow as the recommended temperature for the maximum performance by Bitmain is 25Celcius i just bought those 2 units of a friend that had them cheap, but now I have realize is all about having a nice airflow an engineering already designed an exhaust system for the room (costed me another 1250$), I'll keep you guys updated how this go on regards that if this was a mandatory expense i would not say so keeping a positive air flow is not much of a science i could have done myself but once again i doubt that the landlords would have let me done holes in the ceiling without the engineering's draws.

If you are venting the heat out....why have the portable A/c units at all?

There is an upper wood roof above the ceiling which i haven't been brave enough to open a hole on it which is really neccesary as part of the heat is coming back of the ceiling as it does not have another exit the room temperature remains on average at 90 degrees so i gonna keep them running until i have done the exhaust system designed by the engineering which should be soon after this i doubt that i'll the the portable AC's at all.
