Sorry but you wont make a roi in 6 months, the next difficulty jump is 13 to 17 so how do you work out 6 months to return your money?

agreed...but...
it's already nearly 30% with 4 and 1/2 days to go....     how'd you get 13 to 17?

https://bitcoinwisdom.com/bitcoin/difficulty

clearly says 28.8

Estimated Next Difficulty:   17,351,720,663 (+28.89%)

the 28.89 is the change from 13 to 17 is how much in percentage

no, 28.89 means the estimated next diffchange is upping by at least 28.9%, period....
soon to be higher
I have no clue where you are calculating this 13-17%?

Good grief - its right there in your own post - 13 billion to 17 billion ... !

Neptune's arrived about five minutes ago - Batch#1 order paid for on the 26th November.

I'll let you guys know how they perform! Even though they are late (very late) I am a bit excited :-D



If it is preconfigured with any pool details I will let everyone know.

Coins per 24h at these conditions 0.1121 BTC
How much did you spend on it

In total 13 BTC at $900 per BTC (inc. shipping / taxes).

I've already bought back the 13 BTC at $500, I'm expecting the miner to ROI around 6 months on its own BTC investment but I also enjoy mining and it opens up opportunities for getting some returns on alt's from time to time.

I think you have to take into account the block generation time which shows about 8 min, it's supposed to be every 10 min so the difficulty will be less than 28.8% jump, it will compensate for the 10 min block generation time, maybe I am wrong?

Thats what i mean,difficulty is changing 28%, which is 17 in difficulty
It says the next difficulty is 17 in clear text...

He never said 13-17%.
He is saying it will go from 13 billion to 17 billion.

Bedroom? How old are you? Do you just rent a room or a house or something? You have BIG balls if you are going to run an SP30 in a room. First it's huge. Double the size of the SP10 and weighs quite a bit. When shipped, it is considered "freight" and not a package because it weighs so much. I have 100 amp service, could get away with running my SP10 but the noise was too much. I can just see you....when trying to wash clothes have to turn the miners off, then switch back real quick after the last load. Is you stove electric to? Yikes, can't make that mac-n-cheese when mining away!

100 amps isn't really much, I had that running in a tiny GPU farm in a small office. With the right cooling in place, it was nearly silent. If someone wanted to run an SP30 in a bedroom, I'm sure they could do it, and with the right mods it could be done well.

Not sure where you are in the world, but most american homes use 200-300 amp service.

Newer homes  built in the US are more efficient and don't require amperage like the in the past. That's why you see 100 AMP service for a normal size 3 bedroom 2 bath house now. My house was built in the year 2000, which is considered new in the housing world and came with 100amp service. If the house was 20 years old, I bet it would have 200-300 amp panel in the basement.

FWIW I have never seen a 300A panel in a home.  200A is the highest I've come across and that's usually in McMansions.  Standard is 100A, and I've seen much, much older homes at 60A.

[samsonn25]

I agree, older homes 60 amp.

They didnt have electric ovens, furnaces,  and dryers and water heaters back then.

Coal and gas.

2000 watts(approxomate Neptune draw) / 110v = 18 amps per Neptune. (USA)
5 Neptunes would Max-out 100 amp service right there
Some of us installed 200 amp months ago.... Then, lightning struck... literally

100 amp service means 100 amps at 240v, so that would give 200 amps at 110v.

Volts x amps = watts, Period. You can re-arrange that any way you like.
Watts / amps = Volts
Watts / Volts = amps

But if you really want to save $ on electric, you MUST get a Power factor correction Capacitor
it will save you 20-25% off the top if you are seriously mining
(The scam is electric companies actually charge by the volt-amp, and not by Kilowatt-hours) This corrects that.

That would be 100 amp service at 240V. You have two 120V phases coming into your house each at 100A. Five Neptunes is a lot; but, you make sure your running 3 on one phase and two on the other.

100A x 240V = 24000W

or

100A x 120V + 100A x120V = 24000W

Same power...two phases.

Yes, I agree... also if you use 220v to supply your Neptune, the amps will be 50% less, while the Wattage remains unchanged.

Well that I agree with.

uhh, no.. you can't actually arrange them anyway you want. Only the first and second of your equations are valid, the third should be ( Watts / Volts = Amps )

Do you have data for your installation that shows you are getting a benefit from a PFC?

I don't believe you.

Watts / amps = Volts
Watts / Volts = amps

That's only for DC and instantaneous AC power.  The proper way to calculate average AC Power is via

P_avg=V*I*cos(x)     cos(x) is the P.F.

PS: "Volts / watts = amps" is wrong.

You only need P.F. correction if you live in a area with shitty service.

That would be 100 amp service at 240V. You have two 120V phases coming into your house each at 100A. Five Neptunes is a lot; but, you make sure your running 3 on one phase and two on the other.

100A x 240V = 24000W

or

100A x 120V + 100A x120V = 24000W

Same power...two phases.

^^^^This. With a modest ~2kw in equipment right now, my house is already above 10kw/h part of the day due to 100oF outside.
I started thinking about solar panels, but they are too darn expensive, like 15K for 5kw worth.
In Texas mining looks more and more like a winter "sport".
