Dear waldo , i guess it's best if you get another power meter.
from my previous experience with server PSUs , they have something called PMU , which is abbreviated for Power Management Unit .
PSUs can work in active-active/active-passive , they can work in 20% - 90% capacity and so on.
so measuring one PSU and assuming that it consumes twice the amount can be wrong .
and the reason to do so is that , usually PSUs yield better efficiency in loads greater than 70%.

Revilo, I'm sure if the Terraminer would in reality 2.2TH - you will ask about your 55 GH/s, not 50 GH/s.
So don't insist for this matter - there are others mentioned, more important.

No, Dude. You advertised 50GH/s with a 3% hosting fee.
At no point did you say, 'plus electricity fees at the current USD rate'

The technical specs on cointerra website say Nominal power consumption is 1650W, and that it's supplied with 2 x 1100W PSU's, so how the freaking hell can it possibly be drawing 2900W ??

OK, Waldo, first thing, correction is coming:

Miner no. 2:
one week mining: 1.38932488 btc
one week + one day (??) power: 172$ =  ~0.338 btc (511$/btc)

profit: 1.39 - 0.338 = ~1.051 btc
profit - your 3% profit: 1.051 * 0.97 = ~1.02btc

For 40 shares - I should have ~0,51 btc, and I have only ~0.444 btc...

So, it seems you could still explain, who has made a mistake: you or me...





Second thing:

Everyone says, that Terraminer draws about 2kW power, and you are trying to convince that these particular you have received - suddenly draw 150% of every normal Terraminer. So I decided to ask Soniq (from other Cointerra GB), and let's see how he answered:

"Me: Soniq, do you know power consumption of Terraminer #1?
Soniq: 8.5 amps"
https://bitcointalksearch.org/topic/m.5422641

P = U * I = 230V * 8.5A = 1955 VA (actually: Watt)

Tell us, why Soniq lies in such matter...



Third thing:

http://www.eia.gov/electricity/monthly/epm_table_grapher.cfm?t=epmt_5_6_a
33.69 cents/kWh is Hawaii price - so please confirm here that our Terraminers are placed in Hawaii.

here you have Sy from Germany 0,253€/KWh (0,329 $/kWh) - and he probably won this small world
competition for most expensive energy. (you are trying to convince us, that US citizens have more expensive
energy than EU citizens)
https://litecointalk.org/index.php?topic=4300.msg30129#msg30129


Yes, in such circumstances please do it again...
And maybe it's a really good time for change your energy provider, maybe for even two times cheaper, who knows...
(I'm very surprised you didn't change most expensive US energy provider until now)



So, in such circumstances - maybe a little bit closer to the truth is such calculation below:

Miner no. 2:
one week mining: 1.38932488 btc
one week power: 2kW * 24h * 7d * 0,20$ = 67$ =  ~0.131 btc (511$/btc)

profit: 1.39 - 0.131 = 1.257 btc
profit - your 3% profit: 1.257 * 0.97 = 1.22btc

For 40 shares, maybe ~0.61 btc, not ~0.444 btc...



So please stop acting like it was, if you really care about your reputation on BitcoinTalk.org

You are not the only one impacted by Cointerra late delivery. Not the only - disappointed by small profits.
You could propose flat rate (not 3%) at the beginning - just to avoid such falling profits


P.S. sorry for my "english"

First, I apologize to everyone for my not perfect English, but I think what I am going to write will be understood ...

dear Waldo and other members of the GB,
I'm sorry to write in these terms, but I want to be direct and honest ... but really do not understand three things:

1) the first, as it is possible that the OUR miner consumption is 2900 W at wall outlet? it is practically impossible at electrical and electronics level,
 all users who have read here and on the forums Cointerra to declare a maximum of 2,000 w to 1.62 Ths (a user even w 1800) ... it is virtually impossible that we consume so much with two PSU 1100 W (two PFE1100, maximum 2200 2300W off-specification limit, see the links at the end of post).

http://Forum.cointerra.com/threads/post-your-terraminer-iv-results-stats.385 /

http://Forum.cointerra.com/threads/how-many-watts-does-the-2th-use.186 /

2) regarding the cost of electricity, considering you're in the state of California, and you should (and here I use the conditional) you should use a contract mall, I think 0.20 cents per KWh is definitely more correct of 0.30 indicated ( I do not want to tell you that you are not correct, I just want to point this thing ..)

then according to my calculations (assuming realistically 2 kWh x 0.20 x 24 h we have a consumption of about 9.6 dollars a day, which are $ 288 a month ... I would like to understand why the X2 spending on electricity. waldo .. ... please , Can ypu clarify this crucial point, or all of us ?)

as regards the value of each share now we have a fact that have been undersized from 25Ghs to 20Ghs, but we know on that, at this point there is nothing to do .....

I hope to get some answers from you Waldo, especially on the issue of the absurd consumption of ns. Terraminer  ......

from http://cointerra.com/faq/

"What is the specification of the power supplies in the TerraMiner?


The TerraMiner Has Two Power-One 80 PLUS certified "Platinum" efficiency power supplies. They have a wide input voltage range of 90-264 VAC. The normal operational range is 100v to 240v, I know it will work at all on the standard voltages around the world (110v, 120v, 220v, 230v and 240v). The datasheet for the power supplies can be found here. "...

http://www.power-one.com/sites/power-one.com/files/documents/power/datasheet/bcd.00012_ai_pfe1100-12-054xa.pdf

3) Waldo then a third point, very importantly, continue to refer to + 30% as if it were reportedly scheduled to consumption of 2100 W, but I want to make you see that means that it is more by 30% compared to 1600 W (! (and therefore a total 2000 w 2100 w NOT an absurd 2900W)


from the site of Cointerra Dateline 21/01/2014

"Our production lines are assembling units and we have Stumbleupon for certification simultaneously. The production units That We have assembled and tested so far are running at between 1.63TH / s and 1.72TH / s with power draw at the wall between 1900W and 2100W - Typically 20% higher than our anticipated target of 1650W but still sufficient to operate in a typical U.S. home (110V) plugged into two outlets on separate circuits 15A, or in a typical European home (230V) on a single circuit. "

Miner no. 2:

one week mining: 1.38932488 btc
one week power: 151$ =  ~0.26 btc (bitstamp: 575$/btc)

profit: 1.39 - 0.26 = ~1.13 btc
profit - your 3% profit: 1.13 * 0.97 = ~1.09btc

For 40 shares - I should have ~0,548 btc, and I have only ~0.444 btc...

Waldo, could you explain this difference, please (who has made a mistake: you or me)

+1

Not Cool.
Also I paid BTC4.5 for 50GH of mining, NOT for a percentage of the unit. (Yes i paid the original asking price of BTC4.5 before you dropped the price) I paid for 50GH with a 3% fee and I'm getting 40GH/s at 10x the advertised fee.....

If the difficulty goes up at the current rate and if BTC/USD goes down much more are you going to ask us to pay you for the electricity bill?
Can you provide proof you pay 31 cents per kw/h? Seems expensive.

BTC0.5 out of BTC1.305 is not a 5/6% fee, it's a 36% fee.
And it says here it's ~$300 for 2 weeks, and the miner was working for one week so that should be ~$150, not $280

Yeah.  Waldo has always been pretty straightforward, so I am sure he will.

I am just guessing, but it might be for his time, or a part we need to get mining.  I am sure he will tell us.

I think this has to be a mistake, as the fee is suppose to be 3%.  If the fee is suppose to be 3% + electricity on top of that, then 0.04-0.05 would be the correct area for fees (depending on electricity costs, and how much cooling is needed).  It looks like a decimal is in the wrong spot somewhere.

wow   we just got the things and your feees are WTWhat ? .5btc wow

Cool! Finally!
How come the fees are BTC0.5 on BTC1.305  ??

Received! Fantastic, and thanks.

Very excited.  Anybody know when in march will the second miner be coming?

great day !!!! 

Sorry, I guess I forgot that
