Does anyone know if there has been some national holiday in Israel since yesterday?

No more holidays in Israel for the rest of the year.

http://www.timeanddate.com/holidays/israel/

(New Year's, Rosh Hashana, starts on September 25th.)

I asked because no one has been responding to my e-mails for last few days :-)

nobody responded to my emails, but they send me email today, so I guess that they have a lot of emails.

We are contacting each and every customer about their compensation, responses will be a bit slower than usual this week.

Your patience is much appreciated.

so I got my hands on a few cheap metered APC pdus :
Input: 208V , Connection: NEMA L6-30P , Cord Length: 12 feet
Output: 208V , Connections: IEC 320 C13,IEC 320 C19


I have an electrician coming in to wire to new cicuits for  and he said this :

Now, are these dryers and or ranges you are installing?  Do you have the model numbers?  The old 3 pronged outlets are grandfathered in for repairs only, but for new installs you need (and probably want, for increased safety reasons) 4 prong outlets. This requires 10/3 wire (which has 4 conductors) as opposed to 10/2 (3 conductors).

my questions to experts here :
-the NEMA L6-30P is three prong, but really only good for pdu's and computer stuff, should i let him do the 4 prong outlet and look for an adapter ?

-I don't want to pay another $100 for an adapter for each outlet.  he said something about buying pigtails from APC to convert the outlet but that looks expensive.

-Anoying thing is do wire up the  NEMA L6-30P, seems to require a permit pull which i don't want to pay for.

There should be no problem installing a NEMA L6-30 outlet in a home or business without a specific permit. The outlet is about $50 and the wires to your fuse panel maybe $3/foot. Circuit breaker is about $40. If it's a simple run without cutting holes in walls or running wiring through tricky spots it shouldn't be any more than $350 installed for a 30ft wire run. If he quotes higher get someone else to give you a quote or do it yourself if you have basic handyman skills. (remember electrical safety rules and shut off the main panel before touching wires)

Yeah your right he  quoted me $325 using his breakers , the outlets were around $19 a piece the wires were expensive though I had to buy 100ft since they run in 20 50 100ft increments.  We will see how the install goes today
and thanks.

Very good. I am using p2pool too, there are so many advantages - Low DOA, easy redundancy setup, low orphan block count.... And it helps to keep the network decentralized. Anyway the only difficulty, is the merged mining setup….

p2pool merged mining? I didn't know that was even an option. Any more info on that?

This is fully supported. Anyway, the local p2pool node has to find a block to get the merged coins.

There's a ton of information about p2pool and merged-mining coins.  Currently you can merge-mine the following coins with p2pool: NMC, IXC, I0C, FSC, DVC, HUC.  The way it works is that the node runs all of the appropriate *coind processes and submits shares to try and solve for blocks of each of the merged coins.  To note: the node gets the blocks of coins, not the individual miners.  It is up to the node operator to try and devise a system to payout those coins to miners if that's what they want to do.

Check out the following threads:
Complete Guide to Merged Mining and P2Pool
Setting Up P2Pool and Merged Mining in Ubuntu 14.04

Hope this helps.

So with the  Oct. SP31 @ .00150 gh/s (BTC ~ 471, $3920, 5.5TH, excluding hosting) and the Bitmain cloud @ .00135 gh/s today,
are those of you pre-ordering SP31 machines getting a better deal than the website listed price ?

[Marvell1]

hmm

CISCO PDU RP208-30-1P-U-2 74-8669-01 POWER
data sheet:
http://www.cisco.com/c/en/us/products/collateral/servers-unified-computing/rp-series-power-distribution-units/data_sheet_c78-638923.html

I got two of these really cheap on ebay $80 plus local pickup  hope these work
another local guy is selling this :

APC AP7811
data sheet
http://www.apc.com/products/resource/include/techspec_index.cfm?base_sku=AP7811

for $85 tempted to grab that one as well retail is $500 wow


I think the cisco would provide more power since it rates 200-240 output while the APC is 208V

Is the Cisco one with circuit breakers ? The spec says they're 20A .. so the whole PDU will power only one SP30 .. (2x8A max at the wall)

The APC one is METERED .. more value for the buck (i.e. you connect to it via SSH and can monitor the power usage). Tripplite sells those for $1500 ..

http://www.apcmedia.com/salestools/RZAN-7NWRWD/RZAN-7NWRWD_R1_EN.pdf << here's a picture for the APC one. If you buy it, ask for the passwords.

Argh  thanks I thought even the APC unit could only do : 208x30A which would barely be enough to run two sp30s

So these Ciscos have 20A circuit breakers what is the point of that when it inputs 30A and outputs up to 240V. 

I guess I need the metered one after all.

Thanks

So with the  Oct. SP31 @ .00150 gh/s (BTC ~ 471, $3920, 5.5TH, excluding hosting) and the Bitmain cloud @ .00135 gh/s today,
are those of you pre-ordering SP31 machines getting a better deal than the website listed price ?

1. price is lower with coupon, naturally
2. cloud hashing will end as soon as cost=earnings, and you have no residual rights (to machine)

i don't want to belittle bitmain, as I use them and like their equipment, but i see this cloud as a way for them to get rid of S2 just before the indroduction of something else.
Cloud hashing is for someone who wants to play with bitcoins a little without wanting to mine or buy through coinbase or other exchange.

You are talking about the 'compensation' coupons, right ? They represent BTC or fiat already spent. Nothing free there.
And I very much doubt that the Bitmain cloud is based on the S2.


Why would I buy at .00150 (plus hosting) when I could buy at .00135 ? So that I could have a doorstop at the end of the day ?

yes, it is (plus old A1), just check the relevant thread.

Maybe because if you will not produce more btc that you bought "cloud hosting" for, then once cost=expenses, you will have negative equity and NOTHING else.

[DevonMiner]

Err ... I thought this was the Spondoolies thread ... posts are going a bit AWOL ...  

Back to business, really happy with my SP30s, hashing on average (at toom.im) above 4.5Ths and had a very good day today with my pool.

Also had confirmation of coupon/voucher codes for the GB compensation, thanks Sponds, all looks in order.

Well, if I am in a negative position having spent .00135, I am in an even more negative position if I spend .00150.

And seriously, NOTHING beats a doorstop any day of the week, especially a door stop that cost you a couple of hundred bucks a month to host.

You are in a negative position after spending .00135 because of the high hosting fees where spending .00150 brings you lower hosting fees. But this is an offtopic subject so I will not reply to it in the future.

[Minor Miner]

For those with experience measure KW/hour costs.  Could you please tell me if the following calculation is correct:
1 Month with 30 Days has 720 Hours
24h x 30 days = 720 hours
1 SP30 = 3Kw
To calculate engery : Energy = Power x Time
So the SP consumption Kw/h will be : 3 x 720 = 2160  Kw/Hour
If the price would be 0.1$/KWh then one would pay 216 USD per month?
Thank you

That will be your ENERGY charge.
Most utilities will also charge you a capacity charge (many names for this) based on your peak demand for the month.
plus a transportation charge (for the lines etc.).
Then a whole bunch of other BS.   
It does not seem significant but sometimes the demand/capacity charges can work out to several cents per kWh when you divide them over your bill.
Plus, on residential rates, most utilities have different energy charges for peak, shoulder and off peak hours.

My SP-30 is only hashing at 3003,08 Ghs 240V circuit any recommendation or help about this ?

Right after the miner is started, it will hash at about 3 TH/s. Generally, it will increase to around 4.4 TH/s to 4.6 TH/s within 20 minutes. This variance is due to conservative starting voltages, which minergate tweaks over time to optimize performance.

If your miner is sustaining about 3 TH/s, then you have a problem, and should contact info@spondoolies-tech.com.
