Good Point +1 @ safety first
I like that "getting flak from the little lady" thing.. This is a more immanent (even not more dangerous) thread to the "mining at home" thing, so we should produce solutions where the little lady gets happy with...
Any ideas, guys? Using the thermal power of the rigs for heating a water bed? replacing oven by mining rigs and promising that little Lady will never be in the Need to cook again, cause you can afford going out for dinner instead from the winnings?
How does this affect the rentability?
:-))
HA! Heating a water bed. Keeping the house warm in the winter by placing a miner or two in each room. No need to cook because the miners are producing enough daily to allow meals to be eaten out. All are great reasons to give for allowing mining hardware  I have actually said to the Little Lady, "Honey, look at it this way. My investment turns into more jewelry for you." @iglasses you bring up a very good point: safety first. I'm certainly not implying, nor advocating, people doing crazy things like overloading circuits, leaving bare wires around, etc. I don't want to see anyone hurt in the name of a few extra hashes per second. What are some other setups? Would love to hear what you've done and how you've done it. |

Hello Folks,
Think this discussion should be divided in different regional Areas, cause the Standard power supply settings around the world are significant different in this world (e.g. Europe for a 1L/N/PE circuit at home is 230V 16A which results in 3.6 kW on one circuit, USA same Standard type rates 1L/N/PE 110V 15A results in 1.6 kW on one circuit).
For Europe / Germany:
3L/N/PE with 230V on every L is Standard System for suppling homes.
So if you misuse the cricuit from your oven for example or build up a second oven cricuit (3L/N/PE) 10 kW on one cricuit is no Problem with just having one cable with 5 wires to install, which makes 10 kW. Needed components are sold in every Hardware store. If you build up a cricuit or misuse a cricuit that was installed for a flow type calorifier even 20 kW are possible (3L/N/PE 32A), but here you have to use a bigger cable (4mm˛ (on wall) or 6mm˛ (Sub wall)) and a 3x32A cricuit braker, which both may not be aviable at every little hardware store. Also you really should be familiar with electric installation rules (e.g. in Germany given by the VDE) to do a installation like this, especially cause you should not use the Standard 16A (SchuKo) plugs to connect to that kind of power supply unless you build up a subdistribution in the room where you set up the rigs, which splits the 3L/N/PE 32A supply in 6 cricuits with 1L/N/PE 16A specification.
In other countries with lower voltage or other supply Systems things may get more complicated.
Same for the cooling issue, in cold regions you may even have no Problems when installing in the Basement or in the Garage, because ist f**cking cold there anyway, even during summertime. In other places you need to install a climatisation which at least brings cooling power of 2 times the power consumtion of your rigs. Which means this clima System should be expected to use half as much electrical power as your rigs consume. If I would have mining hardware that consumes power in regions of 10 kW I'd seek for a cooling solution, that reuses the thermal energy from the rigs for the heating System and/or the hot water supply or even to produce electrical energy.
Happy discussion
Great point, and I should have specified that my questions were based upon US systems. I certainly invite everyone to discuss their setups in their respective regions, whether or not they run into power constraints, and what they have done to mitigate them. Funny you mention generators, that was one of the first things I thought of to provide the supplemental electricity. Unfortunately it's pretty cost prohibitive, and if I'm getting flak from the little lady about a couple mining rigs in the basement, can you imagine the hell I'd receive trying to put in a giant generator to power those damn mining things? |

Run a dedicated circuit and make it a 240V 30A. Use a NEMA L6-30 outlet as most PDUs use that style plug. It is good for 80%*240*30 = 5.76 KW.
I'd imagine that's a pretty significant expenditure to get installed. I'm not an electrician, so maybe it's not a big deal to have something like that installed in my home. Got a ballpark figure on something like that? I don't know. I did it myself. It costs me maybe $60 in parts (I put in two outlets and two breakers at the same time) and an hour of work. A lot depends on where the outlet will be relative to your breaker panel. You mentioned having rigs in the basement. If your breaker panel is in the basement, you have room for a new double pole breaker and you don't mind a surface mount box and surface mount wiring it will be a lot cheaper than if an electrician needs to juggle around breakers, put in a sub panel, run some wiring half way through the house inside the walls and through floors, etc. Oh, that's not too bad. Unfortunately, my breaker panel is in my garage, and I'm pretty sure I'd hear some interesting complaints from the little lady trying to convince her to just ignore those wires running through the house I'd love to throw everything in the garage, but it isn't temperature controlled, so the upcoming summer heat would not be very friendly to a server rack out there. Would be fantastic in the winter, though! |

Hey everyone, This topic is geared towards those of us who are mining in our homes, and how to distribute your mining gear within those confines. What I'm really interested in finding out is how people who have multiple TH/s at home are doing it. You so-called garage miners, hobbyists, etc, tell us how you've set things up! Your standard residence has both 15 and 20 amp circuits. Those 20 amp circuits are usually occupied by things like your electric range, washer/dryer, etc. The 15 amp ones manage everything else - outlets, lights, etc. Under continuous load a 15 amp circuit can provide 1440 watts. Since you've got your miners running 24/7, that's what I'd count as continuos load . We'll use the Antminer S1 as our hardware. It's pretty cheap (about 0.5 BTC) and at normal settings claims 360 watt power usage for 180GH/s, so it's a great candidate for the hobbyist. I read accounts on these boards about folks with 6+ S1s running at their home. At most you're driving 4 of them on a single circuit, which would max out that circuit's capacity for continuous load. So, you'll need to consume about 1.5 circuits for your mining. Do you all just shut those rooms down to anything other than mining? Sorry kids, you can't have separate bedrooms any longer, daddy's gotta mine some BTC! I'll share my setup, which is currently 2 S1s. I have them over clocked and both are driven from a single Corsair HX1050. Together they draw about 800-850 watts. They are in the basement for a few reasons: - It's cooler down there
- Not a lot of power used down there on a regular basis
- No more complaining from the significant other about "those damn mining things"
So, tell us your setups! How'd you distribute your miners around the house? |

OK, I could use some clarification as the two answers seem to contradict or else I do not understand something.
All I care about is the "Best Share" stat. I don't care about the value of the corresponding hash, unless that is the same thing. Is it as simple as looking for a value of 8000872134 (current difficulty minus 1) or is Best share a different value? I guess even though I know what it is, I don't know what "Best Share" actually represents.
Best share represents the highest difficulty share your miner has found. If that value is greater than the target difficulty of the block, congratulations, your miner has generated a block. If that value is lower than the target difficulty, then it is meaningless. |

I was inspired by the OP and setup solo mining on my graphics card. The software i am using is cuda miner. It now says "stratum detected new block", does this mean that i have found a block? If yes, should i focus more mining power to the miner so it mines the block?
No, you haven't found a block. It means that your mining software has been informed there's a new block on which it needs to work. |

Yeah, it confirmed this morning. Again, thanks for giving back to the community.
I didn't see the threshold discussion, but had tried playing around with the patron_sendmany on my node to see what would happen. Now that I know about how to set the threshold, it makes a world of difference in the number of addresses receiving part of the donation.
|
|
|
|
|
Would you mind explaining/sharing the command you used to change thresholds and send the donations? Looking at the P2Pool merge mining guide doesn't really explain things other than to say, "To make a donation to everyone use the following..."
Thanks!

Glad you got I0coin up and running. I had it, but it never synched with the network, so I dropped it. Maybe I'll try again |

Thanks, Posted here before the other thread, other thread gets read more At the moment it's just me in the pool.. Ok, so if you're looking just to have your node merge mine and to reap the profits for yourself, then check out the instructions at the beginning of this thread. In the other thread you can see the exact values I use for my configuration files as well as the startup command I use for the p2pool node. I can confirm that it works as my node found a BTC block, and I received block rewards for all of the merge-mined coins. |

Congrats. I am mining by doing the math with a pencil and paper.  As of late you are more profitable than most ASIC miners so...go you! Six more ants are now in my clutches...'bout to leave the 1 club and join all the other dreamers at 2Ths...ugh. I wish I was addicted to alcohol or drugs...I can get Obamacare for that shit now! HAHAHAHAHA! Do you have your own personal data center or something? How are you drawing that much power? |

I've got a couple S1s hashing away and have been looking to up my game to the TH/s club as well. I can get the S2, but I've also been looking at the SP-10. Of course, I could pick up 2 S2 for the price of the SP-10... but it's a question of power at that point. I'm setup at home, so I have limits on how much power I can draw . Of course, if I could find a nice cheap data center willing to rent me cabinet space... oh wait... I've gone off topic. SP-10?  Nevermind, found it on spondoolies. Yup, the spondoolies one. RoadStress is running a group buy for $3200 a unit... 1.4TH/s. I can get the S2 for $2199 (coupon) and get 1TH/s... both draw about the same 1000 watts. Personally, I really like the looks of the SP-10, and it's now just a question of "does the SP-10 offer me enough value to justify the extra $1100?" Of course, there's also the question of explaining exactly why I just spent that much money on "another one of those mining thingies??"  |

I recently started seeing these errors in my p2pool log - and I've never seen them in the previous month of running a node: Anyone offer some advice on what's going on here? I've got the latest version of forrestv's p2pool software from github, and like I said, I only started seeing this error today. EDIT: I'm not sure what, if any, effect it's having, since it appears my miners are still hashing away properly. The S1s each show a very high Accept:Reject ratio and hardware errors are about 0.1% It's one of the web frontend pages requesting the share with the hash "undefined," which of course makes no sense. Looks like a bug in the Javascript code somewhere. Are you using an alternative web frontent? Thanks for the reply. I am using an alternative front end - a mixture of john doe's interface and some custom stuff that I've written. Just weird that this would pop up today. I'll replace the front end with the standard one you provided and see if the errors persist. Will report back here shortly. EDIT: removing the custom front end, putting in the standard one and restarting my node results in the same errors thrown. EDIT 2: And just as quickly as the errors started appearing, they have not again appeared for the past hour or so... wacky. |

Noob question here...
If I set up merged mining, how will my miners get those coins if they only connecting using a BTC address as there username?
You asked this in the p2pool thread, and my answer was based upon the assumption that you were the only one on your node. If you're asking how to get the DVC, NMC, IXC, etc to other people who are mining on your node, then that's a manual process. If you are merge mining coins and your node finds a BTC block, you will by default find blocks for each of the coins you're merged mining. The coins are NOT distributed amongst all of the people mining on your node, but rather they are all deposited into the nodes' wallets you specified when starting p2pool. Here's an example: You have a BTC p2pool node that you started and it merge mines NMC. You have 100 miners on your node. Now, let's assume that one of those 100 miners finds a block. That miner will be rewarded with the BTC block finder's reward (0.5% of the block's value). Your node wallet will be awarded the block of NMC (currently 50). If you want people to actually be given NMC, you'd have to setup a way to register those people, and their NMC wallet addresses. Then, when your node finds the NMC, you'd have to distribute the block reward out to those registered miners using some kind of reward system (probably PPLNS). All of this you'd have to code yourself. Good luck |

Despite the fact that I'm still the only one on my node, I just divvied out the funds. I had to set the threshold pretty low otherwise only about 6 addresses would get anything. Most users (myself included) got about dust, and who knows long it'll take to confirm, but it's something. Now if more ops would do this it would add up to something. 2a8dda6727186bce7a44d10b66cdca4287fdca5b6f47b39fb374bd54bbb7c748 M Thank you for your contribution. It was definitely dust, and has yet to get a single confirmation. That, however, is not the point. The fact that you are giving back to the community is. As I stated, should my node ever find a block again, I will also donate the proceeds gained from the merge-mined coins. |

Point it to the wallet If I understand correctly, you're looking to find a way to solo mine some alt coins by setting up a p2pool node for it? Couldn't you just use a stratum proxy and point your miners to it, and have the proxy talking to your wallet? |

So the ultimate custom dashboard quest continues.... Added "Recent Shares Found For This Node", the most recent 20 shares are displayed [Age-Miner-Share]. It's at the bottom of the page: http://mining.coincadence.com/I'll add an ajax updater once I get the rest of the data I want on the page (so I only have to do it once). What do you think? edit: adding the last 10(?) blocks is next, hate it when there is no "recent blocks" data displayed Looking good. Edit: I should probably at least make an effort to provide some kind of feedback other than it is looking good. Now that you've listed the shares, perhaps link them to a "share details" page that might give more information about the share itself. Things like share minimum difficulty, actual difficulty the miner hit to solve it, etc. Or, maybe instead of just listing out the last X shares, provide a "best share by active miner". You could even incorporate that into the "Active Miners" table. As a miner, I'm interested in both how the node is doing overall, and how my individual miner is doing in relation to the node. Sure, the node found 20 shares, how many of them were mine? What was my best share? This is what I've been working on with my node. |
