It's working exactly as it should. X number of transactions contribute to the total Y you send. If X is larger than the amount you want to send, you will get X-Y back.

Really depends on what your definition of common mortal is.
Mining can be fun, but the upfront costs to purchase hardware can be expensive. Sure, you can get an Antminer U2 for like $10, plug it into a USB port on your computer and mine away. Are you going to earn anything significant? Nope. Will you earn something? Sure.
Buying/selling can be fun as well. Purchase some BTC and play the trading game.
Got some items/services you want to sell? Check out the Marketplace forum - get paid in BTC.
Lots of options to get into the game are available to you.

Looks like a Ponzi scam to me. If you are a U.S. Citizen, I suggest you start by contacting this organization and asking for help in creating a believable and compelling Ponzi scam. LOL... an excellent organization to help you learn everything you need to know. |

Am I reading this right, to import to the USA you need to give fedex your social security # ?!!!??
Yes, you are required to fill out an Importer's form. You either provide your tax ID (if you are a business) or your social security number (if you are an individual). The form is from the Department of Homeland Security, US Customs and Border Protection. It is an Importer ID Input Record. |

Assuming you've got the extra PCI-e connectors and the PSU has the power to spare, no reason why you can't.

Hey everybody- Just got my SP10 today and so did my Dad. Both of them work great and we had them up and running in just a few minutes. I also just upgraded the firmware. A little icon exclamation mark near the button "firmware upgrade" appeared, so I upgraded and it only took a few seconds. One problem I'm having though. The noise. I really didn't think they would be that loud. These are truly meant for the data center and the build design should have clued me in on that when I saw it. My father is also a little perturbed about the noise level. So we are wondering. Can these be ran with the unit opened up and the enterprise fans turned off and use another type fan/blower to keep it cool? Has anyone done this? I know I should have known they were this loud from the design, but for in-home use it may be just a little too loud for me, and my father also. We both agreed we would sleep on it and make a decision soon on what to do. Has anyone here cooled an SP10 in any other way then using the stock enterprise fans? I really DO NOT want to sell it or be without it, but there is a limit to what I'm willing to do. 1. So, if we do decide not to keep our rigs does Spondoolies have anykind of return policy? I looked all over their website and couldn't find anything. I think this is the first thing I have ever purchased without knowing if it had a warranty and if it could be returned or not. I know this is a very touchy subject with companies, but both of them are in perfect working order and of course we'd pay for the shipping cost to send them back. I guess I should send an email to Spondoolie to from their website and ask there also. I don't know if they monitor this thread or not. 2. Me and my Dad both live in NJ. If we made the decision not keep our SP10's would anyone be interested in buying them? They are both already in NJ, so you wouldn't have to wait and could possibly have them up and running this weekend if we made the decision that quickly to sell them. I myself would really love to keep it, but being that I live in a ranch style house there's really no where to place the unit without it being heard from every room. And then I need to keep the window air conditioner on 24/7 in there to keep the temps at a decent level. I only have a 6000 BTU window unit and that's running on high right now and the temperature in that room is 78 degrees. I'm just thinking ahead a little bit and wondering what kind of melt down I'm going to have when the temperature outside is 95. I I know I really should have done a little more research, but I really got hung up on getting another miner. I still use and run my KNC Jupiter, which is in the same room...adding to the heat, but that unit run literally silent. I'm usually a more picky buyer and don't buy out of impulse, but what I really feel guilty about is I talked my Dad into buying one also. I told him it would be "noisier" then our KNC's but really didn't tell him it would sound like a Jet Plane.  I think the Spondoolie is built like a tank and works great. I just wish I had a data center rack somewhere to put it in. It wouldn't be cost effective to lease rack space, since it would cost more then what the miner would bring in. I did send an email to Spondoolie asking them these questions also. Maybe they can just host our SP10's if we are able to ship them back to them, who knows. I don't know how much it cost to lease rack space in a data center, but probably in NJ it is quite high. Maybe that's something else me and good ol' Dad can look into as well. Well, thanks for listening and sorry for such a long winded post. Yet another miner from NJ! Thankfully I'll be running mine in my basement, so noise shouldn't be an issue for me. If I had enough power to run 2 more, I'd take them off your hands. Unfortunately, the little lady might be quite upset if I tell her she can no longer use any electrical appliances whatsoever because I need all the power to mine BTC |

Thanks, it cleared it up. It was the multiple wallets that made me second guess the intuitive, logical comprehension but I get it now and appreciate your clarification. A BTC is a BTC no matter how many wallets you have. Using your example of a dollar being broken down into quarters/dimes/nickels, etc, let's assume you have a dollar bill. You break that dollar into 4 quarters, and you store each quarter in a different place: the pocket of your jeans, the nightstand by your bed, the drawer in your desk and the piggy bank. If you move all of those quarters to your jeans pocket, you've still got 4 of them. If you have 4 BTC wallets, each with 0.25 BTC you still own a total of 1 BTC. |

Hi Windpath, thanks for the info here, im running some s1 and was having hard time with google on a definitive response to setting the pseudo share.
couple of questions
1. is 0.00000116 a static constant, or based off dynamic number? Wondering if i need to redo the math periodically to keep my miners running efficiently.
2. do you know of any downsides to restarting p2pool, i noticed i lost a few shares once i had done so, but technically i dont understand why that would be. i did however update the -a payout address, perhaps that restages the pool?
3. "expected time to share" seems to stay around 7-12hrs, im assuming its because the pool doesn't have any stats to work off of yet?
4. "payout if a block were found NOW" seems to remain at 0, any tips on that?
5. know of any p2pool advanced docs/manuals out there?
Thanks for any info
Great questions, gigabitfx. I'd like to add to the information that windpath has already provided: 1) Setting pseudo-share difficulty determines how many shares from your miner that the p2pool node evaluates. In p2pool, your miners must submit a share of a given difficulty to be considered. For example, if you set your pseudo-share difficulty to 1, every single share your miner finds will be considered. It makes the graph look very smooth, but floods the node with useless traffic. If you set the pseudo-share difficulty to 1024, then only shares that are greater than 1024 will be considered. The graph looks very spiky, but the node doesn't have to deal with the extraneous traffic. The p2pool node will assign pseudo-share difficulty automatically based upon the node's combined hash rate. If you're running your own private node, you really don't need to bother setting either pseudo-share or share difficulty. If you're mining on someone else's node, then you might want to set them if the hash rate you're contributing is significantly higher/lower than what the node currently has. 2) You won't lose shares if you restart your node. Your shares are stored in the share chain. The default behavior of p2pool does not persist your node's shares across restarts (windpath solved this by creating a database); however, rest assured that every share you've found is part of the share chain. 3) Your expected time to share is based upon your hash rate and the current difficulty target. The formula is exactly the same as the expected time to find a block of BTC: Difficulty * 2**32 / hashrate / 86400 = number of days to find a share It has no bearing on whether the node has been running for a while or have any stats to work with. 4) This is kind of misleading since it isn't well explained. This value is the expected payout to the NODE's wallet - not to your miner - UNLESS your miner is the same wallet as your node. So, let's assume you have started your node as: ./run_p2pool.py -a SOMEWALLETADDRESS If you configure your miners with the user name "SOMEWALLETADDRESS" then that expected payout if block found now value will show what you expect. If you configure your miners with the user name "ANOTHERWALLETADDRESS" then that expected payout value will show 0 (unless you charge a fee to mine on your node, in which case it would show whatever charges have been assessed to your miners). 5) I don't know of any advanced manuals. The best information I've found is here on these forums, the p2pool wiki and through reading the p2pool code. This thread is a great place to learn, although going through nearly 440 pages is kind of painful  Hope this helps. |

Definitely want to consider other hardware options. At 5+ watts / GH it's exceptionally inefficient.

Kano has an S2 now and is working on official code for cgminer that hopefully will rectify the behaviour of the driver they included with it.
Good news for S2 owners. |

It would be nice to hear from others with S2s on p2pool to find out if the same loss of hash rate occurs for them as well. Unfortunately, I don't have one to test, either. I will, however, have an SP-10 delivered tomorrow - which unfortunately won't be hashing until Saturday evening because I'm on the other freaking side of the planet. I will definitely be trying it out on p2pool, Eligius, BTCGuild and GHash.io to see if there are any significant differences in hash rate.
Anyone with S2s running on p2pool?

Anyone have issues getting their products through customs? Mine is being held right now in the US and they won't deliver it until they get more paperwork for it. I called Fedex and they said it needed more paperwork and emailed it to me. I asked Fedex why would I be filling out paperwork for a shipment when I'm the receiver? I tightly planned my work schedule around this delivery and plans and this is causing a big headache right now. So I call Fedex again and they email me papers and ask me to fill out. I told them I'm just the receiver and don't know what to include on these papers and they should have come from the shipper. Anyway, I filled them out the best I could earlier today and it still indicates a customs delay. I'm really hoping I get some good luck here. I'd hate to have a $3000 product I paid for be sitting somewhere at customs in several states away.
I also got a customs delay with my shipment. Within a few hours, I had received a phone call from FedEx asking me to fill out an importer form. The form took all of about 30 seconds to complete - it was just my name, address and importer number (which since I'm not a company is just my social security number). I emailed that back and the package was released from customs. All of this I was able to do while sitting at JFK waiting for my flight to take off for Tokyo. The girl I spoke with at FedEx was very helpful. She said the reason I had to fill out this form was because the value of the shipment was greater than $2500. Now, since I've filled that out and it's on file with FedEx, any future shipments from Spondoolies-Tech will be cleared. |

Have you limited the number of connections for bitcoind and/or p2pool? You don't need to worry about the variables you posted - they are defined for each coin.

Hey windpath, I like what you've done so far, and storing historical share information is a pretty cool idea - a miner can look back and see variance over time. Personally, I'd rather see the timestamp instead of the pretty date format. Seeing "Found 2 days ago" for 6 shares doesn't tell me the distribution of those shares. Also, I'd love to have the luck of one of the miners on your node... same hashing power as me, but his expected payouts are double mine. I looked at his history for the past week and it's not like the payouts started that high, they started low and have just kept on rising, whereas every other miner has some kind of up and down curves - which is more in line with what I'd expect to see. Can't wait for my SP-10 to arrive and point that at p2pool |

I've been trying for days and I cannot get a CPU or GPU miner to work on a Mac. I'm aware of the miners that are available, ig0tik3d and elmads. The farthest i've gotten is with ig0tik3d's minerd. But using the osx64 compiled verision downloaded at http://sourceforge.net/projects/cpuminer/files/, terminal says "./minerd: unknown algorithm -- 'X11'". Any help would be greatly appreciated. Happy mining! I was able to get a fork called sph-sgminer to work... kind of. This was back in March when I was playing around with it. I've got a late 2013 rMBP15 with the nVidia 750m and Iris Pro. No matter what I tried, the clBuildProgram just kept throwing errors when trying to build for the nVidia kernel; however, it did work with the Iris Pro. Again, this was back in March, so perhaps there have been some changes. Here's what I did: 1) Grabbed the source from @Badman74 git 2) cd to sph-sgminer 3) autoreconf -fi 4) automake 5) CFLAGS="-O3 -std=gnu89 -march=native" ./configure --enable-opencl --disable-adl 6) export GPU_MAX_ALLOC_PERCENT=100 7) export GPU_USE_SYNC_OBJECTS=1 You can see the full thread of what I was doing here: http://www.asteroidapp.com/forums/discussion/402/support-for-sph-sgminer#Item_27Good luck, and if you manage to get it working for the nVidia cards, let me know. Also, I haven't grabbed CudaMiner lately, so no idea if anyone has written a fork of it there, but back in March, nobody had. |

Sorry, it is hard to read 105 pages quickly when trying to make a quick decision. If I were to order an SP10, would I receive that from stock right now and would that pay itself off? I currently have an KNC rig going at 560GH/s right now, but just wanted to add a little more. Also what I'm worried about is the power supply. These don't come with power supplies, so which power supply would be a good one for an SP10? And do these ship from the US or abroad? Just trying to decide to see if a purchase like this would be worth it. With rewards so low, I would want to at least break even....at least of course.
Thanks.
p.s. does the SP10 need external cooling to keep it cool at all, or all the internal fans do their job?
Yep...they are CURRENTLY shipping from stock...$2.795 + S&H... Yep...SP10 COMES WITH it's own power supply...in the box... No...made in and shipping from Israel...by DHL...or FedEx... ROI...I don't know...you do the math for yourself...I am waiting for $1,795...maybe next month... Good luck, buddy... ZiG Sorry, another question I forgot to ask....I did look on their site for this information, but couldn't find it. After placing an order, what is the approx time of delivery to the east coast of the US? I'll let you know when I get mine. Order #1356 placed on 5/20 paid by wire transfer. Being sent to the east coast. |

Interesting setup. You're using p2pool locally with no connections to the network. I'm assuming you've got bitcoind running on one machine and that's connected out to the internet, and p2pool running on another machine with no connectivity to the internet. I've never seen it used this way, so I can't tell you explicitly whether or not you're properly solo mining. Having written that, it certainly appears to be executing properly - the payouts look like a block reward, and the expected time to block of 12600 hours would seem to be pretty accurate for your 180GH/s. You must have your very own share chain that is being created, with only your address having valid shares in it... the difficulty is silly low because the entire pool is 180GH/s. Most people when they solo mine just point their miners to the bitcoind and have at it. I like how you improvised and setup a p2pool network of 1 |

Spoke with the great guys at Spondoolies last night - they were extremely helpful and answered questions quickly and succinctly. I was impressed enough that I placed an order for an SP-10. This morning, I start the fun international wire transfer process, and by 3:00 this afternoon local, it clears and processes. Within the hour the price drops. LOL... I feel like Maxwell Smart... "Missed it by that much!"
RoadStress, I'd like to thank you for putting together this group buy with Spondoolies. I can't wait to get my new SP-10!

Thanks for notlist3d, this trial can't process without his effort. Thus this trial will temporary closed until we find a member as reliable as notlist3d to take this task.
Indeed, thanks both to notlist3d and to you pcfli for offering up the opportunity to taste some of the good life . I wish I had been able to join in the fun, but alas was too far down the list. I would offer up my services to take over for notlist3d; however, I will be traveling to Japan for work next week, and am unable to dedicate the time required until the first week of June. |

Tip for warm rooms: It seems that the SP10 runs better and more stable at Normal speed than at Turbo. Try it!
Can you be more specific reference "runs better", meaning your getting a higher hash rate? Thank you, ~Blaise Getting 1.45Th/s at Normal speed. With turbo I was reaching 1.50Th/s or 1.52Th/s, but from time to time it slows down at 1.40Th/s. I guess it's from the heat. I really need that 5U rack. I think your numbers are better too because of being in the PRE-May batch. Mine would only run at 1.05 in quiet mode when it was suppose to run at at least 1.2 but would never come close. I had it tuned and its running steady at 1.42 each at tuned TURBO settings by SP-TECH staff. I think at normal Id be lucky to get 1.15 or 1.2 quite honestly with this May batch. So you're running at 1.42TH/s on turbo. Are you in the US and connected to a standard wall outlet (120V/15A)? It would be pretty disappointing to top out at 1TH/s - and would greatly sway my decision on having it shipped or hosted. EDIT: I thought that quiet mode was supposed to run at 1 TH/s @ 700 watts. |
