Hello! Today I received a new Rockminer R-Box, but I don't have a power supply for it. Instead of spending another 10 dollars and ordering yet another power supply, I did manage to find something that may or may not work. I know this might be a silly question, but I don't know a whole lot about power supplies and such, but here it goes: The Rockminer requires 4 amp, 12 volt, 45 watt power supply. I managed to find a 16 volt 4 amp power supply. Would this just break the device or would it work? Thanks!
death to your device.think of amps as gallons . so big amps means big supply to draw from. so a brick/lake with lots of amps never runs out of juice/water thinks of volts as gallons per minute. or water pressure in the hose so to speak. hi volts will over whelm your device burn it up fry it. next advice the r-box requires a 12volt 5 amp device for 24/7/365 12 volts x 5 amp = 60 watts times 75 percent = 45 watts. what is 75% your safety number for 24/7/365 run time.

AntMiner S3 NEWS
The Second Batch of AntMiner S3 runs out of stock. The Third Batch of S3 sales price is dropped to 0.725 BTC each with international shipping, which will open sales at 22:00 pm on July 4th (UTM + 8 ). The Third Batch is most likely to be shipped before July 20th, but no more than one or two days delay may happen.
I am waiting with great anticipation for my order place on the first day. I sent a good plus trust for you today for the 11 s-1's I purchased from you. I am hoping to be able to send a good plus trust for my s-3 order very soon. Thanks for being a decent seller. Philipma1957

Ok so the main function of mining is to sign transactions right? So if time between blocks is ten minutes and people doing BTC transactions are expecting those transactions to happen almost instantly the we need either more hashing power or a drop in diff immediately? (or both)
Am I seeing this right? I've seen m's pool monitor predict a drop for the last few days as well, not sure what that is based off though.
his math is based on current block making speed. if blocks are 10 minutes about +- 1 % if blocks are 9 minutes apart +- 10% if blocks are 8 minutes apart +- 20% very rough math. I will give you a second thing to keep in mined diff jump avg from jan 2013 to now = 23% avg per jump But diff jump avg from Dec 2013 to now about 18% avg per jump Also I link you to this one: http://bitcoincharts.com/ Diff now 16818461371 Diff est 16669791571 this one: https://bitcoinwisdom.com/bitcoin/difficultyBitcoin Difficulty now: 16,818,461,371 Estimated Next Difficulty: 18,380,239,968 I take Diff est: 16,669,791,571 Estimated Next Difficulty: 18,380,239,968 Total-------------------- 35,050,031,539 / 2 = 17,525,015,769.5 diff which is 4.2 percent jump Now about 14-15 hours later using the same method I get a 3.6 percent jump

You know what I like about Bitmain ?
They never bitch if their thread goes off-topic and the shills are civil.
More than you can say about Spondooles.
~L)L~
Well the sp10's and sp30's are sold with a completely different method and with different style of miners then the s-1 or s-3. BTW I have now found a second post to agree with you. oh and and back on topic did you buy one or 2 s-3's like I did or did you stay on the sidelines.

might not not be enough for 2 ants at max overclock of 554Gh It's only got 6 PCI-e, so you couldn't over clock the two anyway. Should work fine for 1 overclocked and 1 stock. incorrect about total number of connectors-see philips post however, with rebate it looks like a great deal if you don't plan to overclock to the max Yeah you're right. I saw six cables and didn't notice that two of them are doubles. So 8 total. Even so you're stretching the capacity of the psu running 2 s3s on it. I'd go with the 1300, which also has the same cabling. Nice catch and thanks for pointing it out! EDIT: I just picked one up. Thanks for the link to Amazon phillma1957! $188.99 - $35 rebate for a total of $153.99, free 2-day shipping with Prime membership. Heck of a deal ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) you are welcome . they are very nice gear. the fan is a tiny bit loud when pulling 1215 watts doing 3 s-1's at 200gh 393 freq. My s-1's are now underclocked.. waiting for my s-3's to put my second 1300 evga back to use.

the 18% diff jump should be correct over long term.
Only for a few more months. 6-12 months out, we'll be seeing under 18% jumps regularly. 6-12 months out we could be seeing: bitcoin regulation bitcoin usurped by another coin with better PoW power efficiency huge increase in the price of energy another hack that finally destroys confidence in the infrastructure a bitcoin fork to improve maximum transaction rate and validation times rampant greed amongst remaining mining conglomerates etc, etc, etc A meteor can destroy the earth. Don't forget the 3-rd World War... ![Grin](https://bitcointalk.org/Smileys/default/grin.gif) I hope not... How about an alien invasion for our water? Or global warming speeds up so fast all the ice melts out in under 6-8 weeks. BTW this one does scare me a bit. But I guess more like 2 decades.

Well it's a week since last announcement, no sign of shipping?? Are DZ even ready to do the hosting if/when they arrive? I've seen absolutely nothing from them on that. On a brighter note we have started receiving KNC units in my other GB, so at least hashing somewhere (and they are doing two for one compensation!)
that is good. that deal may be helpful. my gut tells me this one may end up a bust out.

I push the 1300's since they will do 3 with no oc =really sure about this and they can do 4 with under clock/undervolt = hope to do this. I did 4 s-1's with ease could have done 5 with the under volt-- down clock .

Should work fine for 1 overclocked and 1 stock. people keep citing this 6 pci-e number, but it is incorrect: it has 6 cords, but eight connectors-see on pictures (it is clearly visible; two cords have double pci-e, bringing total to eight) yep i just posted this about the 1300 watt model at amazon it is a super solid deal 154 after rebate... also if you have a discover card or a chase card you may be able to get it cheaper .. here is how . this is gasoline discount quarter with some chase cc's and some discover cc's. go to a gas station that sells amazon gift cards and buy 150 worth of gift cards with your chase or discover card. they will earn 5% so the 150 is really 142.50 .. So you can buy the evga 1300 psu for under 146 usd if you can do the gift trick and the rebate. monster deal for s-3's

I was reading the op and no longer see the 100 a week I see just 400 max per month.
This fine by me as I figure to make 450 TO 500 POSTS this month.
So I do not need to track weekly any more. First week I did 125 or so second week I did 125 or so.
Right now on the 16th or 17th day I am over 320. I do like this way as it keeps down the super posters and a 400 limit is
really close to what I would normally do.
Thanks again stunna and if you celebrate it {Not sure if stunna is USA based}
Have a happy fourth of July.!

All those neptunes and s3's wont make the network go up higher. You can't add hashrate twice. That's what the recent jump was about. When they sell them and they get turned back on the hashrate doesnt go up again. It's already been factored in.
Which I think is the point being made. The assumption is that the drop occurs during the period in which the new miners are being packed, shipped and installed on the customer end. If that is true the its a false drop and very very temporal. It will be for 10-12 days or 1 adjustment . most likely it will be a 4-6% jump not a drop

your question is? the next diff jump will be or are you asking something else? I estimate jumps by looking at two sites. https://bitcoinwisdom.com/bitcoin/difficulty = 16,818,000,000 to 18,389,000,00 9.34% http://bitcoincharts.com/ 16,818,000,000 to 16,659,000,000 = - .95% they do 2 different methods do get the next increase I have found the correct number to be in between their estimates so 4-5% is a good guess for next jump.

okay your cat 5 wire is direct connect pc jack to s-1 jack ? next if it is you type in 192.168.1.99 and no connect? do an ip search use advanced ip http://www.advanced-ip-scanner.com/free download it will pop up all addresses on the network. 1) so first unplug the pc from the s-1 2) connect the pc to the net 3) go back online load the scanner. 4) then connect to the s-1 5) scan for the s-1 6) if nothing shows change the pc to .0. my guess is

so the point is 'DO NOT MINING'? am i right? so if that's true now is time to move on altcoins ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) I'm writing a guide on why altcoins are, practically all, fated to fail. I'll make it short here for you: everybody is accepting BTC, NOT altcoins. Everybody is building infrastructure on BTC, only some accept some altcoins. Everybody is investing in BTC, only some put something into altcoins. If you have some exceeding money to trash, buy some altcoins and hope that in the future at least one will step up, otherwise stay far from them. mining bitcoins is bad, altcoin is bad.. so what's exactly you ask us to do? trading with big loose? or stop thinking about bitcoin and go away from this? I ask you nothing. And even more: I am nobody, not economist, not guru, nothing. It's just my opinion, but if you open your eyes a bit it's not too difficult to try to forecast this environment. Just buy BTC with fiat currency and wait. Not the right time for mining, not the right time for buying too many altcoins. IMHO. dear godlike like your name. it is a nickname use for a close friend. while respect your opinion of buying coins (btc ) and holding them. It is a one dimensional approach . I best guess is do mining and hold coins. In order to do mining you need cheap power. So some guy in iceland at 5 cents a k-watt with an sp-30 doing .5 watts a hash is in good shape. well 2 antminer s-3's pulling 750 watts to do 1000 gh are better if the power is 3.5 cents a k-watt. So small miners will survive if they are creative about power. Does it mean steal power no it does not. Here are great uses for 2 s-3's http://www.lemproducts.com/product/refurbished-stainless-steel-dehydrator/refurbished-productsfood dehydrator http://www.wood-database.com/wood-articles/drying-wood-at-home/kiln drying wood those products spend the same power with out mining if scaled correctly. So that means free power for your miners. These are just a few ways to compete against a huge Iceland spot. Another way is any free power source of more then 100 watts use gear to solo mine. Cost = zero chance of collecting small. but the idle gear will not make money. and mining for free it could get lucky. Small miners will not die off. Simply because they will adapt. They just won't have a lot of the network. Of course a 50ph plant in iceland would be a huge target for terrorism but that is another pair of sleeves so to speak.

I just received an AntMiner S1 and have connected it to a laptop with a crossover network cable. I am unable to get to the log on screen when I enter the miner's IP address 192.168.1.99 in my browser. I tried pressing the reset button and still nothing. I have TeamViewer in case I need help troubleshooting the issue.
okay you need to determine if your network is 0 or 1 most are 0 or 1 192.168. 1.1 192.168. 0.1 so maybe look under your router see of you find the 0 or the 1 I have a dlink it is 192.168.0.1 so all my in network gear is set with .0. to have an instant work around I have a cheap older laptop set to 192.168.1.1 I never use it online I use it for antminers. I plug it into my antminer and setup the s-1's I then plug the antminer into my home network with it changed to something like 192.168.0.230 with sixteen done so far the last 3 numbers are used from 230 to 246

I strongly suspect that we'll see a glut of mining hardware on the market in Q3 that hardware manufacturers can't sell at a profit, which will lead to consolidation and some companies folding.
Would you care to elaborate on this? This is difficult to ascertain, in my opinion because we don't have their profitability numbers. I just hope that the scammiest, lying companies will not survive. People in mining are incredibly forgiving, even stupidly so. Without a technological breakthrough, ~.5W/GH looks to be about the limit using current technology, and we're rapidly approaching the point where multiple companies have fairly equivalent hardware (Bitmain, KNC, Spondoolies, and Bitfury). Future power efficiency improvements are going to be very hard to come by. There are fixed costs associated with all miners for things like heatsinks, fans, power supplies, PCBs, board components, chips, manufacturing, and shipping, so there is a lower limit on miner pricing. We know that Bitmain was able to make a profit when they sold the S1 at ~$250, and I suspect they can do the same with the S3, which would put the bottom floor cost of a S3 at around .5$/GH. Spondoolies sold the SP30 at .69$/GH for the Roadstress group buy, and they have said multiple times that they won't sell hardware at a loss in SP10 discussions, so I strongly suspect their SP30 costs are around .5$/GH. S3 ROI numbers look iffy at $1/GH and a ~17B difficulty, so who is going to buy all this new hardware at a 34B or 51B difficulty if the price to manufacture the hardware is ~.5$/GH? Unless the price of BTC goes up, I think we're rapidly reaching the point where it no longer makes economic sense to manufacture new hardware, and will reach that point in Q4. Well make the wall .5 watts the lowest power prices are 6 or 7 cents a k-watt make btc at 700 usd so with that in mind . when diff reaches 447g vs the 16.8 g it is now . no one can make any money. If you believe this is going to continue btc will have to be higher then 700usd by feb 2015. maybe 1400 usd by feb 2015 or no gear is not worth buying if bitcoin truly takes off, mining equipment (or 240v hookups and 300A panel) plus a small solar panel (2-5kw) might be included in some new housing construction. I agree with the calculations, but it all depends on the price. With $2000 BTC tomorrow, antminer s1 will be flying off ebay at $400 and above and people will be fighting for preorders again. yep and price has had a history of big runups.. under 100 in sept to more then 1100 in nov and 11x jump from 650 usd to 7100 usd would make all gear good again well . Any gear at 2 watts would be decent if price runs up. I move slow now no more jumping in I get 2 packs or 4 packs of gear. I make and effort to stay under 600 usd worth of btc. I made an exception buying the s-3's since I spent about 940 usd worth of btc for 2 of them , but I created a solid paper trail of: bank account > coinbase> my btc address > bitmaintech. I will not buy more until I get these in my hands and they work. So my next order may not be until Aug 1st. more likely July 15th - 20th

It isn't and every one of you posting this is wrong.
I have bought batch one S3's I will profit with them If you can't I don't really know what to say.
S1 owners like phillip (see above) took a chance and got lucky due to KNC, BFL, BA and others delivering late. I have free electricity and I was still skeptical about ROI. Considering all that late stuff is now delivering, I'll make a 1BTC bet with you that your S3 won't ROI it's BTC costs. With the 25% jump this last period it's going to get nasty pretty quick. Btc roi is really soooo hard to do. I no longer make bets but I would think that to get a s-3 to return its cost of .75btc is not going to happen for most of us. USD roi is always possible. Now many say but if you purchased the 0.75btc and held it 1 year later that was a better profit. Yes it is true that buying low and selling high may make more money. But I am a USA guy I follow USA rules. Buying coins and holding them is passive investing as per USA tax law. Buying a miner mining with it and then selling it on ebay involves up to three types of tax rules. 1) mining which is an active business 2) resale on ebay I have an active ebay store 3) holding the mined coins . which is about the same as buy and hold tax law wise. Many forum members are fully underground. So they have different condtitions to consider then me.
