661  Other / Beginners & Help / Re: Useful Desktop Applications for Bitcoin ? on: March 20, 2016, 09:07:56 PM
It will be hard to push any bitcoin related software that requires a download, because people are rightly concerned about trojans or bitcoin stealing programs. Even so, the thing I'd find most interest in is a live stream of the price of bitcoin without having to visit a website. You could maybe include historical data and price tracker as an easy reference tool. It might already exist, but can it be improved?

As I stated , the program will be Open source and anyone can compile it himself and check the source code so he make sure I'm not trying to steal anything from you or infect you with trojans .
now about your idea , I'm not sure I get you , Do you mean like charts etc ... ? or something like preev.com ?

Yes, something like preev that updates itself constanty combined with graphs showing the past price of bitcoin in US dollars. It would be useful so people can lookup the price of an item at the time it was bought - if they can't remember.

Yeah I suppose that shouldn't be an issue

Could anyone tell me why this topic got moved to Beginners and help section ? It's a project so logically It should stay where it was "Project Development" section .

I guess a mod didnt actually read this and moved it here because it looked like another newbie asking another newbie question.

How about a rainmeter skin with bitcoin statistics? From the obvious price ticker, last day trend to the optional TX rate and TX backlog count. A cool feature would be recommended fee per kB.

He is also spamming the Ethereum forum with this nonsense.

AISC, sound scary.

ASIC is totally possible, but what's the point with Eth going PoS soonish? Also, i'm not a low level code/hardware engineering so i can't say in full certainty, but i'm fairly sure the cost for development would be high and take quite some time. It sound like a stupid venture. Eth could die, if it doesnt, ASIC will become useless at PoS/algo update. People may even flat out agree to change algo if an ASIC come by.

Anyways, when you spam this stuff and you can't even get the term's acronym written right, you dont have much credibility.

Don't know why everybody is scared of the cheap ribbon risers.

Never had any issue with them.

I always check with a meter for shorted pins before plugging in a GPU and they been running for years.

You can also just mod some PCIe extender wires and instead of plugging them into the molex plug them into the CPU plug from the power supply. Just re-pin the +12V and Ground pins.

They're a management mess. The USB are much cleaner for cable management. They are also superior because the PCI-e power connector from the mobo connect to a deadend.
665  Economy / Computer hardware / Re: WTB : PCIE USB Risers - complete on: March 20, 2016, 07:11:49 AM
so the ethereum bug bit you too, pal?
yeah, ebay and amazon sellers jacked up the price per riser from $8 to $14.
what's wrong with delivery from aliexpress-same stuff, half the price?

I've been doing eth for a while now, so it's nothing new. Just need a few extra ones.
I don't like ali express as it's another chinese junk peddling company.

where to you think 70% of the manufactured stuff you buy is made in?
besides, US sellers sell the exact same stuff (which they simply buy in bulk), but with a 100% addon in price.

That exactly where the 3 resellers i know get them in bulk, at 2.x to 3$ per. Bitcoinware is the dirtiest though, i bought with them because they said they were in stock, then they said oops, they're not. Been waiting for 3 weeks for that order. I could have ordered from China myself without the markup.

But they refuse/ignore request to resolve the issue.

I don't think you will have much luck selling that type of board here. The ATOM CPU is painfully slow and the motherboard only has 2 PCIe slots so not good for mining either.

But the ram is good.

The ram is DDR2, so doesnt work with current high PCI-e slots DDR3 motherboards for mining either, sadly. Maybe someone may want this for a (very) budget gaming computer.
667  Bitcoin / Mining speculation / Re: Free Elec - Avg Temp 18š - Budget 30k. Start or not? on: March 20, 2016, 01:42:37 AM
I will give you the same advice i give everyone start slow.  To jump in with 30k would be a bad idea, growing pains from adding so many miners... would happen.  But don't let me stop you from mining totally as free electricity is very good.

So my advice start with a few, buy a few coins.   And get use to watching gear managing BTC etc.   Start pretty slow don't invest your whole 30k.   Eventually if you keep doing it... maybe one day.  But not starting out.

Hello thank you for you answer.

I was only expecting to sell BTC, i am thinking as normal business donīt expect to speculate so much with the price. Just think about if i invest 10k for example in Miners with refrigeration system how long will take till i get money back..

If i check the difficulty it makes me not to invest.. but so many people doing it

So many people losing money, yeah. If the ROI takes more than 3 months(right now), its pretty risky. Aim for 2 months ROI. With used hardware and free electricity its definitively doable.

For most 2-3 month ROI is pretty hard to do.  Long ago it was common place. I don't think we can say it takes 3 months as with difficulty changing... even with free it's hard to speculate.

I have not seen anyone who can accurately predict 3 months of BTC mining anymore.  Just to hard to predict.

With strictly Bitcoin its a bit hard. If you score a S3 for 30$ you have 1.5 Months ROI. S5 for 100$, 2.2~ Months ROI. Assuming free electricity and reusing PSU's you already have on hand.

For the S5's you need to be close to a Datacenter that's selling out. For S3, or i guess S1's would work too... but it would have to be local pickups.

But who is selling S3's for 30 dollars? I just don't see major sales for this price unless I'm missing something.  If you get on here I think it's closer to 50 + shipping.   So don't see the 1.5 month ROI.

And go over to ebay and it's even higher to buy them.  So still over 1.5 months.

There's a guy selling for about 60CAD not too far from where i live, so ROI there is about 2 months. They havent been selling, so could probably haggle them down. But directly locally i've gotten them much cheaper. Even at our cheaper electricity here, they don't profit anything. (1.7USD per month @ 0.06).

Within Canada to ROI them + shipping, they would need to be 30$. Getting S3's at 20$ locally was kind of a fluke, but at the same time, S5's going for 120$ or less, its not all that much of a stretch.

Just looking at the forums now I still don't see S3's for 30 or 20 dollars.  I don't think most are going to be that lucky.  You are right if you got them at 20 with free electricity.... heck of a bargain.

But I think 50 + shipping on most out there.  And ROI math.... hard to say.  I just don't see the ad's supporting 20-30 dollar S3's.  If you can get 20 dollar especially you could turn a profit flipping them on ebay at that price so I just don't see a big amount of sellers in that range, most are higher.

Right, they're 60CAD on the forum, so two month ish ROI. Assuming diff is going to stick to the +3~4% range for a while. If you can haggle them down, it's even better, but you need to pick them up yourself. If you have them shipped, you'd need to have the seller eat the costs. Otherwise S5's are just better deals by far, even for free electricity.
668  Bitcoin / Mining speculation / Re: Free Elec - Avg Temp 18š - Budget 30k. Start or not? on: March 20, 2016, 12:45:48 AM
That is actually not true, every example you listed still requires cost for the electricity in some form or another.

Hydro - yes it is that cheap, but it is still not free.
comes down to near free - again, it is not free.
solar array setup - extremely high costs to run a couple of S7's, the amount of space and cost associated with setting up a solar array to power 30k worth of equipment would be so expensive, over the life of the miner, you would be better off just paying over 50 cent a kilawatt for power.
small hydro turbine - again, extremely high setup costs and you would need a large hydro turbine to run 30k worth of S7's.

So again, there is no such thing as free electricity.  The main point I was getting at with my post is that every now and then, someone comes along with subsidized electricity for whatever reason and I am usually the person paying for it through my tax dollars.  This really pisses me off that they get to think they are getting free power and get to mine for free, when they really aren't, and instead of tax dollars going to something good, they are going to paying for these people to mine.

You're not even providing any information, you're just plugging your ears and saying Nonono not true.
I'll elaborate, since you, honestly, don't know what you're talking about;

-Hydro IS that cheap. This means that you can pay a flat fee for access to it and not pay more for a higher usage. It is near Free as in you won't pay more if you use it, its so cheap its included in rent. The downside is you have a amp cap on your sub-panel.

If you don't pay more for higher usage, this mean your access to the electric portion you will use for mining is effectively 100% free. You're not consuming more fuel or any fossil fuel. Using more electricity does not equate to the Government spending more money. No one is shouldering a higher bill because you are using more electricity.

Saying you're not mining for free here is just incorrect.

-Solar array equating to free; You are also wrong. Look at phil's setup. There is an upfront investment and the goal here is to Zero out his complete electric bill. Then he can run miners on his array to recoup the cost and soon profit on a repaid array while it last.

I'll give you an example since the concept of obtaining free electricity with an investment on an array seem to baffle you: If you do $50k USD out, then receive $50k USD in... your + or - at the end is 0. 0 Seem pretty free to me, since he then have electricity he doesnt have to pay for 20~years.

The actual numbers are more complicated but thats how it is conceptually. If profits with mining just get that bad, he can simply sell the portion he'd use for mining and sell it back to the grid.

Yes there's an upfront cost. Yes he's able to mine for effectively free at one point. The portion he'll use for mining, he won't pay more for it versus his mining earning, therefore it is effectively free.

-Turbines, you have no idea what you're talking about. You can get compact, long turbines, they're really not that big and they generate the electricity 24/7, so no need on a big expensive battery setup. Its cheaper to setup and a solar array as well.

This is the option i know the least about. But I guess it doesnt matter, since you didn't actually provide any actual information to support your claims or your logic.

If you have something to say beside repeating what you seen other people say about free electricity, as in actual details, please share. Otherwise you're just wasting people's time repeating misinformation.

Hi, Is it possible to get functionality similar to paypal adaptive payments with bitcoin? Specifiably I'm trying to split one payment into percentages and send it to multiple people, who would each have their own wallet.

It is possible, but i dont know a wallet with such automated function. You'd need to trust a 3rd party with software that would manage received transactions to a certain address and then generate multiple outputs.

Exchanges and services already do that, but i don't know if there's a non proprietary/open-source software that you could use.
Are you aware of any software that does this? It looks like it might be possible with the blockchain api.

Like i said, i don't know. Ad Campaigns make use of it with a bot to do it, yeah. Blockchain.info is buggy as hell though. Maybe check blocktrail.

Is there a particular reason you want the entire blockchain downloaded? You can just use a SPV wallet like Multibit HD and you wont need to download the blockchain then. There's several options on bitcoin.org;

671  Bitcoin / Hardware / Re: Some random thoughts on avalon 6 antminer s-7 and j4bberwock/finksy boards on: March 19, 2016, 04:35:16 PM
That seems more like a problem with the breakout board than with the Avalon, and kinda verifies some of Optimizer's testing and concerns about thin copper.

it is both but you are not wrong I would say you are ⅔ correct.

Asking a pcie jack to handle 250-275 watts dc is asking for trouble.

and the optimizer testing   along with my temps finally getting warm enough show a flaw in the  boards in that the air that comes from the psu blows warm and hits the back of the pcie board and does nothing to cool where the pin meets the socket.

the fans pulling air directly across the connection and not behind the connection are a good cheap fix.


a better board with more copper will help the socket on the psu end not melt   which is where I think you are fully correct.

but on the avalon 6 end the same issue is there and a perfect psu side may simply move the problem to the avalon 6 side  pcie jacks.

for now the fans will keep the break out boards safe.

I was going to have y cables made   that would be a pair of 18 gauge cables into the  break out  board   and then connecting to a 15 gauge cable into the avalon 6

which would mean 8 break board jacks into 4 avalon 6 jacks.   this would solve the issue in that the break out jacks would do 125 to 150 watts max.

but it allows for a lot more power into the avalon 6 jacks.  as much as  400-500 watts per jack in case of a loose connection on the avalon jack side.

So I concluded that the fan idea is best in the short run.  I do suggest a 3 jack avalon solution for the future and a heavy copper  fix for the  break out boards.

Mean while if you are like me and have 2880's and avalon 6's watch for this.

the fan solution really seems to work. also note I have the top jacks of the break out boards filled as they get the most cooling from the fans.

Hmm, i've run high quality fat retail EVGA 1600 cables at close to 350-400W though. They never browned. On the Avalon6 i'm using standard retail PCI-e and they are still fully cold.

How long did it take for your jacks to brown?
672  Bitcoin / Hardware / Re: Have you seen this new HOTMINE Bitcoin miner-DHW heater? on: March 19, 2016, 02:54:03 PM
So this is supposed to be using the new bitfury chips?  Wouldn't that make this the first publicly available miner that does so?

EDIT:  Oh I see on the website they are only claiming the high-end one uses the new chips.  So they all have the same electricity usage but hashrate varies by chip used.
http://en.hotmine.io/#pricing

That hashrate to kilowatt ratio is in the range of what bitfury claims for the new chip according to my back of the napkin calculations but according to bitfury claims on efficiency that would put it at the very bottom end of that range (or maybe slightly under it actually).

EDIT AGAIN:  Oh now I notice where it is a pre-order. They all are, but the 16nm one has the furthest out date with Sept of 2016.  So maybe or maybe not the first publicly available device with the new bitfury chips.

The last time I made a comment on this boiler for home heating I was told to STFU.

So I will not say anything other then that.

WHO TOLD YOU to STFU regarding this boiler? I need to have a talk with this person.

It's already been mentioned in at least 2 other threads in these forums.

Can you please provide links if possible? Thanks so much.


I went back and found a link:
my post
https://bitcointalk.org/index.php?topic=1368053.msg14038427#msg14038427

and the STFU post
https://bitcointalk.org/index.php?topic=1368053.msg14038793#msg14038793


The guy was out of line, like others replied afterward. You really should not pay heed of that STFU thing.

But anyhow, thats one of the thread. The home heater is a bit gimmicky, since every ASIC already do that Wink

Bitmain has shit service, to say the least, so i may not be inclined to buy from them anymore. However they do deliver their short term pre-order, if not a bit late or DOA/crap hardware.

I'd advise to anyone to reject any scam/rip off pre-order thats 1 month + ahead of time, however. In other real life scale, pre-ordering ASIC... is like pre-ordering a 2018 car, to be received in 2038.

Don't forget also that there is no such thing as free electricity, someone is paying for it, it just may not be you.  Said person may not always be happy to see a utility bill jump the way it would by adding 30k worth of gear onto the system either.  Food for thought, don't screw over something good you have (aka free electricity) until you can be absolutely sure its OK and you are not cheating anyone (aka Taxpayers or someone else).

Electricity is just really that cheap in places with Hydro Electricity. Or maybe someone live in a place where electricity comes down to near free... Or maybe he has a solar array setup, that once bought, the cost of the electricity over the estimated period of the panel's lifetime, it comes down to free, or he has a small hydro turbine.

TLDR; there is such thing as free electricity, copy pasting the typical ad sig campaign reply isint helping anyone.

Its hard to reference, i've also seen it mentioned several time. Its not a new concept either, to say the least, but a plug and play heating solution could be nice. Its basically a water cooled miner however, it already exist.

I'm guessing it would need to have an integrated shunt on a thermostat built in to dump the heat outside to actually be a home cooling option. From looking at the designs it doesn't look like there is one, in which case it would be nothing new.

The heat seem to be sent directly to a main Radiator which use ambiant air to cool itself, which mean you would not have a way to direct the heat where/when you need it.

Would there be any reason not to use this cheaper counterpart;
For human safety, wires inside walls must not move.  Therefore wire must be secured by an appropriate device where it exits a wall.


I would not run the cable inside the wall, i'd hang it by the ceiling. Why would it matter if there's a twist lock preventing the connection from being pulled live? As far as i understand thats how it would be set up in an industrial warehouse or a Datacenter?

Is the danger that the cable somehow get ripped off from the electric panel?

Hello VirosaGITS,

Is there a risk that transaction fee won't decrease as BITCOIN get more and more value compare to fiat currencies?

thanks

Yes, the fee per TX would go down if "we" increased the block size. Or up if not as people compete for the same limit size per blocks. I particularly do not see a problem with this however.

Anyhow, the TX fee is more tied to available space than BTC's value.
