Interesting GB.
Is there a way to not allow dual mode so that other users in "DIY mode" don't cause grief for the rest of the miners?
In other words if someone does not follow the guidelines and produces too much heat or causes circuits to blow what will be the course of action?
Thanks

Ye if only they had offered a full BTC refund to those who wanted out, if only  

I guess you are already at the head of that line

Technically, the 6 pin pci-e connector is only "rated" via PSU specifications for 75 watts. A 6+2 or 8 pin is rated for 150 watts. So, in theory, the PSU manufacturer could use higher gauge (lower amp) wire in a 6 pin only configuration. Also, if it is a multi-rail PSU, the 6-pin rail may not have enough amps. A PSU I have explicitly has 6 pin and 6+2 pin connectors. If you look at the amperage available on each rail, it explains why.

If you are looking to be conservative I would say 60w per wire pair within the PCIe connector. At roughly 10w per device that is 6 units per wire pair and 18 units total, conservatively. It is possible to go up to 80w per wire pair but that just stresses the housings, pins and wires and will yield lower MTBF rates.

Looking at a molex 'chain' there is only a single 12v wire pair to be utilized there but it is shared. This is going to limit you to 60w on the entire 'chain' (usually 3 molex plugs and a floppy).

Hope that helps.

Hi everyone.

This may come as a surprise, but I'm hoping it will come as good news to everyone out there.

I am eliminating any premine on this cryptocurrency.  I plan to do all the implementation of it over the next 4-6 months on top of btcd.

Looking back at all the cryptocurrencies that people actually have faith in, such as Bitcoin, Litecoin, and Peercoin, it seems like the only practical and fair way with which to launch a cryptocurrency is by doing so without the premine.  The people who will benefit from such a model will be you, the future users.  In the spirit of everything that this community has ever been about, it seems only appropriate to try to develop this myself while I live off of my own savings.  It'll be a rough road ahead, but I hope I will have the continual backing of the community for choosing to develop this for everyone's benefit with no monetary expectations in return.

Development will formally commence tomorrow, and I have left my job so I am free to work on this full time.

I will still release the software as binaries for the first month or two, then formalize a public github repo (to prevent initial forks).  I'll have put too much of my life into this by the time of release to have it forked as whatever-coin in the first couple of months, and I hope the community can agree with me on this sentiment.  Any members of the community who wish to audit the code are welcome to talk to me.

Hey CoinHoarder, I just sent payment and PM'd the requested info. 

Thank You.

What are you using for power solutions in your farm?

Expected would be somewhere in the first half of April then?  

Is it also possible to do the DIY solution with less than 50 units (I'm interested in 10-30, haven't decided yet). This because it will need it's on Raspberry Pi to control it, while it could actually be hooked up to 50 according to your OP.

Are those circuits powering UPS's then out to all the 120V psu's?

You have a total of 16 120V 30A circuits to use.
Why not feed all the psu branches that way?

How many total 30A circuits do you currently have available?

I'm pretty interested in letting you host 10 of these.
If I'm correct this will give me around 3.0-3.3MH/s hash rate in grid seed scrypt miners?
If I were to order in the coming 1-2 days and send you the BTC payment directly, what is the ETA for the miners to be running?
I would prefer the 'do-it-yourself'-solution.

Thanks for any answer!

I'm running cpuminer - Scrypt only version, on Windows 7.
How may GS5's are you running? No problems? No failures?

Hey cablez,

Can you give some specific advice on wire gauges so I can add it here: https://bitcointalk.org/index.php?topic=494625.msg5511232#msg5511232

My 6 GS5's ran for 30+ hours this time before they stopped mining. I'm using cpuminer  - Scrypt only - version.

After chasing up this problem and trying to solve it over the last few weeks, I've tried virtually everything short of re-programing the firmware on my miners, which I cannot do - obviously.

Darn it!!!! Right after I went to sleep, it takes a piss! AAarrrrrrrrrrrrggggggggghhhhhhhhhhh!

I wonder if GridSeed engineers left this but in their miners' firmware?

Has anyone been running their GridSeed Farm 24/7 stably WITHOUT ANY INTERVENTION WHATSOEVER?

IF so, please tell me what your configuration is so WE can all set these things and not have to worry about this elusive little bug!!!?

Has anyone come up with a macro to take care of detecting the hault then restarting each miner in cpuminer?
All I need is for it to monitor the window of each miner and when it stops producing yay's for say, 3 or so minutes, it stops the program without closing the window, resets the port, then restarts each miner 5 seconds apart.

Thanks

I love the pic of the all the 30A sockets how many do you have and how many volts ?

You mean say, 1 to 2 amp fuse per 10 units running in Scrypt. Spec's say 5000mA max. So this would be a good current limiting range to use to prevent any possible serious problems. The 5 chip units will ever pull anywhere near 5 amps while running Scrypt mode. As I recall, in Scrypt, they pull around 480mA max.
If they trigger a SHA session, the fuse will simply blow and that will be that until it's replaced. Perhaps a charge for having to reset them for trying to mine SHA would be appropriate as well.

Ssssssssssso cool! An instant line of credit from the word go!
So lets say I order 200 units, you give me the first 30 days FREE while my miners make me several thousand dollars over that period. On month 2, there comes due the first months rent which will be $2200 bucks. Piece of cake to pay out of my 200 miner's profits. And I'll be receiving the difference in btc on the same day....right?
You will earn two entire months of mining before paying the first hosting fee, because the hosting fee won't be taken out until month 2's payment which comes at the end of month 2. So yes I think you'd easily make hosting fee and profit first few months. Especially if the hosting space reaches capacity quickly. Anything after that is anyone's guess on what difficulty and value will do over the next few month.

How long will it take to pay off my 200 miners? Does it depend on mining profits made and how much of that revenue is devoted to paying off the miners over time? Is this right?
You simply deduct your fees and send me the balance every month?
I don't guarantee that you will make any profit, you may lose your money. This is a risky investment and please only invest what you are comfortable losing. I suggest holding BTC or LTC to diversify a little bit. No one can tell the future though. I think if you hold on to all crypto mined you'll be a happy man in a year or two regardless how this mining venture turns out. Again, no one can tell the future though. All I can promise to to provide a nice hosting environment.

After the miners are paid off, what does the hosting fee become then? Is it lower? Or does the difference become more profit for you?
The hosting fee will always be determined by how many units are being hosted. If we fill up the warehouse quickly then I will be looking to expand elsewhere to reduce hosting costs even more. My hope is that by the time profitability lowers that I can lower the hosting fees even more to help with profits in a few months+

Thanks!

Let me know if you need any technical advice / how to info' etc. I have quite an extensive resume of years experience in several technical / mechanical / practical hands on / engineering fields. Electronics, electrical etc. etc. etc. All pro! No Micky mouse here!
Heck, I might even volunteer to help you out in person.
Wolfey2014

Ok will do. I might ask some advice when wiring up this 88 Gridseed PSU contraption. I'm a little nervous I might of messed up or something, but I'm pretty sure I got everything right. It pretty much took me all day today to figure something out... I went through 3 revisions and finally settled on something I think will work perfect.. 3rd times a charm right?

The best way to prevent any potential fires by overloading wiring or psu's is, just don't have that potential to begin with by either current limiting via fusing / circuit breakers at x amps or wire the miners up to be able to handle the power increase if SHA is activated. You'd use 14 gauge wire to each unit, well more than enough current carrying capabiilty for 12V with a limit of 30Amps per 10 units. They'd never exceed that rating, even while mining SHA. The only other problem is having the front end capacity to handle the increased power usage of the psu's.

One other option, LOCK out the ability to mine in SHA no matter how the end user tries to make it work!
I would think this is possible via some software tweaks? Make sure the contract is written to reflect this too.

Great idea! Good stuff!
So am I to understand that if I rent or rent to own 100 to 200 units, I have to pay out a hosting fee of anywhere from $1100 to $2200 per month?:

The hosting fee will only be that high for the first couple months if I had to guess. One of those two months is free anyways. We have had about 100 units reserved in a week. If this pace keeps up we will reach full capacity in a few months and hosting fees will be dramatically lower.

What happens after they are paid for? I can either have them sent to me for my own personal hands on or just leave them there and use them to make 'us' money? You your hosting fees and me my profits.


Yes it is up to you what you would like to do with it. I can mine with it for you, sell it for you and give you the proceeds, or ship it to you if you prefer.

What are the odds of my miners paying all of that by themselves from day one?

Quite unlikely, but due to variance it is possible I guess. But again the first months hosting is free, so you would need to start worrying about the hosting fee until the 2nd month. I think the fee will be lower by then.

At what point do I become 'owner' of the hardware? i.e. Psu's, controllers, miners etc? What exactly am I buying - if I go that way? Miners and support equipment or just the miners?

You own the grid seed units themselves. Unless you buy at least 88 units you do not own all the accessories, they are shared by the group. I will provide what I can when sending/selling your unit. It depends on how many you buy as to how I can split the accessories up.

So I just send you my btc# and you set up the number of units I order, start them mining and making profits and if at the end of the first FREE 30 days they don't pay the rent / hosting fees, I have to pay if out of pocket?

No. The first month is free no matter what. You will only start paying the hosting fee at the end of the second month. I project to have around 600 units hosted by then, so you can guesstimate the 2nd months hosting fee like that.

Will the program e structured in a way that this will always be profitable and only become unprofitable if the market take a very marked dive? I mean in that case, it would hardly be worth continuing with the program, eh?

No. I have no control over the profitability of the units. They could very well be unprofitable next week for all I know. I am not liable for anything not under my control like price crashes, difficulty increases, etc. if at anytime the devices don't make the hosting fees I will give everyone the option to sell their units, pay the hosting fee out of pocket, or ship back your units.

On the opposite end of the spectrum, The price could skyrocket leaving us profitable for quite some time or difficulty could not rise as fast as you'd expect. No one can tell the future!!

My farm should be making me a profit and hopefully paying some of my other bills too

Thanks for your ideas and offer to do this for people. I think it is very needed and wanted!
This could cause a boom in the mining side of the game which is what we need to help this industry grow and continue to be around from now on!

Cool

Thanks for your interest, let me know if you have anymore questions.
