Anyone check to see what affect this mod does to SHA mining?

With this mod, 7w only mode is using close to 40w? I'd guess that if you try running SHA256 Mode, might as well just toss it in the trash.  Undecided

This mess is because LeaseRig has two separate logins - one for renter and one for leaser (provider).

The login for provider is only accessible via link http://23.236.58.114/?page=admin (there is no menu item/icon on LeaseRig maing page to this "provider login"). And once you're logged-in you can not change your provider's password.

The other login is for the renters (customers) - this is via the "LOGIN" menu item on the LeaseRig main page ... and when you're logged in as the customer (renter) you can change your password - but this only changes the password for your's "renter" account ... for the "provider" account still stays intact ...

That said - the first thing on the to-do list would be to merge those two accounts/logins into single one so that one "person" can be leaser&renter at the same time with one account ...

THIS

Just create two user groups using a single sign in: Customers & Providers. Users with the "provider" tag will have access to the admin page.

Also, thank you Ken.  Smiley

Personally, as a developer for LeaseRig.net, I can tell you our goal isn't "What can we get out of the site?".

It's a lot more like "What can we do for: the site, the customers, and the providers".  With a lot of "Where can we add value?", and "How can we make this platform more secure and efficient for everyone?" too.

Everyone says this at first. Time will bear it out.  Wink

I'm glad someone called out that statement about the GPU rentals. I was thinking it, but didn't want to stir the pot. Mostly, I'm concerned about the intense pressure being put on rental prices when you have 10 providers for 1 renter. There was definitely a race to the bottom as people were pricing below even multi pools for a day or two. The pricing pressure isn't the sole issue either. You've got guys like Hostkey with 35 identical 2 GPU rigs listed, pushing everyone else way down the list. That visibility costs business.

There perhaps should be a better design that tucks additional rigs under each provider name, listing their best prices and their largest rig in the list, until you click on their name to see everything they offer. As it is, the provider-slide that happens because of this is causing a secondary pressure on pricing just so people can stay visible on the first page. Otherwise, it seems to make more sense to me to list (20) 400KH/s rigs, and (20) 765KH/s rigs, and just play the same game. It would be a pain to manage on my end, but it's getting out of hand with the current design.  Undecided

As to the 2.5% fee, I would certainly welcome any reduction in fees. not the least of which is the transaction fee that sometimes makes up 1.25% of the total amount I get paid for a rental. Either hold the BTC until it reaches a good threshold, make the renter split it with the provider, or absorb it in the website fees. Betarigs charges less, but they have middleman syndrome and get in between the transactions too much for my taste.

Q: Will the sites fees remain the same?
A: The fee will stay at the current 2% or less and we have no plans to increase it.



So, did you reduce it to 2% or mistype. It's currently 3%, plus .0001 BTC TX fee.

Are GridSeeds really this fragile, I purchase 10 and 6 are defective do to a PSU short ? ( is this possible)

Hello Gridseed users.

I purchase a 10 unit GridSeed package that came with a Raspberry PI and 10 port USB hub and two 10A 120 to 12 VDC PSU'.

I connected all the 10 GridSeeds to a the USB hub and powered it up,  then I connected a 1 group of 5 gridseed to a 10A 12 PSU (XHY PV-12012000) using a fan out 1 to 5 power cable supplied with the kit. The other 5 GridSeeds were connected in the same way.  I powered up one group of 5, and when I plugged the second PSU I huge spark was seen on the 12 VD DC line of the 1 to 5 fanout cable all the fans started and then stopped.

I unpluged the PSU and tried it on only one GridSeed and the PSU was dead. It's green LED was no logner on and my voltmeter showed no 12 volt reading.  I then tested each of the 5 Gridseeds and not one would power on, Could they all have died, I though impossible but I got out a better quality 120 to 12V transformer made for CB radio and the 5 devices no longer powered on, and when directly conntected to a USB port no led.  The continuity tester on my volt meter shows a short on all of them !.   

So I powered-up the other 5 Gridseeds left the room for a few minitues, when I returned all of the units has stopped and the fans where vibrating a making a whining noise.  I noticed that the PSU's green LED was flickering.  So the second PSU was no longer able to power the load of 5 Gridseeds not even mining.  I later discovered that the second PSU was only have to operate a Gridseed for a few minutes before apparently dieing out. 

I purchase this kit from Zoomhash.com, and I opened a support ticket.  I've played with electrical gadgets for a while and have seen my fare share of cheap made in china power supplies die. But never have I seen damage on this scale occur so fast; Out of my 10 GridSeeds only 4 work after this "incident", 5 don't even power-on and the 6th powers on but the USB circuit appears dead and the internal LED never come on.

I am really regretting that I did not take the time to test each unit one at a time on my PC to determine that each was working properly as I was so excited to and wanted to get the devices working fast.

I'm still at a lose as to what might have cause this chain of events ?  Could a short in one of Gridseed has caused a leak of the 12V dc in the USB circuit and back in the USB Hub and back in the other GridSeed's ? The USB hub also is dead.
 Huh

Picture of PSU that I suspect was the cause of all this destruction.




Dude, use IMG Width= tag please.

Important USB HUB Warning From Zoomhash.com
View this email in your browser
Dear Customer,

All USB Hubs must be powered by 5 volts. Please double check and make sure you do not make a mistake and accidentally power your USB hub with any other sources other than a 5 volt source.

Make sure you do not power your hub with the same source as your Gridseed Miner. (Do not use the gridseed miner's 12 volt power source).

Especially if you are cutting wires from another ATX PSU.

Thank you.

So, here's a question... (Generally Speaking) People don't mine BTC, pools mine BTC. Individuals do 'work' for the pools. So, in this particular interpretation, the pools bear the burden of tax responsibility for having mined the coins, correct? If you were to say that because an individual actually finds the block, and thus "mines" the coins, wouldn't that make the specific individual responsible for the tax burden of the 25 BTC? I fail to see how the wording of their statement, strictly interpreted, incurs a tax burden on individual miners.

Based on the wording of the IRS' statement, I don't believe they really understand the process. Certainly, I think they are hoping the the 'threat' of the IRS is enough to convince people to pay taxes on income they (at this point in time) can't possibly track or regulate. Also, what does this mean for people mining every *other* crypto? I don't mine BTC, but I get paid in it. Their statement doesn't cover currencies of the week, or even LTC for that matter.

I was looking at my miners today as I was desoldering the fans and I noticed that there are actually two different builds of the gold models. The new ones use smd leds and have a 2nd chip under the large grey one, while the older ones use standard LEDs (much brighter/better IMO) and have just solder pads and only 1 chip under the large grey one.

Not sure the relevance, but I thought I'd mention it.

Changes:

  • 8GB card req (didn't have a 4GB handy)
  • Passwords: root/darkknight pi/darkknight
  • Default pools on first boot are set to mine for charity

Note: My MEGA account is free, so limited bandwidth. I'd appreciate anyone else who can redistribute it.

93  Alternate cryptocurrencies / Mining (Altcoins) / Re: GridSeed 5-chip USB miner voltage mod on: March 27, 2014, 03:28:14 PM
2. There are a theoretical problem: you will never get higher average pool hashrate than local average hashrate in long term. Cgminer's hashrate calculation based on how many jobs are finished in a second, whatever its result(you got a share or it has no solution). Pool calculation based on how many shares are submitted in a second. It depends on luck, but as Law of Large Numbers says, in long term it has to be same as your local hashrate(in an ideal environment: no network latency, no stale share, no rejected share, etc.).

Actually, ghash.io often over reports my hash rate, incl the 1h & 1d averages, by about 25%. Use a good multipool like coinshift or clevermining for more accurate pool rates. The graphs have a finer resolution as well.  Wink



Also! For anyone who wants to have a slower fan, but DOESN'T want to power it via USB, try inserting a 47ohm 1w resistor in the red wire to drop the 12v in half. It's important that you use a 1w resistor, as it will be dissipating about 3/4w.
94  Alternate cryptocurrencies / Mining (Altcoins) / Re: [GUIDE] GridSeed Miner Support/Tuning on: March 27, 2014, 02:24:31 AM
I really wish they'd get cgminer running for the gridseeds - even though cpuminer works great it can't be monitored like cgminer with it's api.

Yeah... there are already like 10 versions of CGMiner that support gridseeds. Some for BTC, some for LTC. Google it.
95  Alternate cryptocurrencies / Service Announcements (Altcoins) / Re: [ANN] BETARIGS.COM - Cryptocurrency cloud mining - 2000+ rigs online to rent! on: March 25, 2014, 01:01:56 AM
Mux,
Renter walkingglitch has rented and cancelled rigs after not paying multiple times on my rigs on 2 different accounts.
Check his activity and plz block him
Also yesterday, there was sudden demand for n-scrypt and when my rig became available, walkingglitch  rented it , blocked it for 30 minutes and then cancelled rent. By that time rent had reduced 4 time son n-scrypt. This is either rig owner blocking other rig or customer blocking rig and waiting if another cheaper rig becomes available. Untill u get wallet for site, Rig owners will keep getting frustrated.



This

Is not a problem I have on Leaserig, because payments to me are made immediately. The moment someone rents out one of my rigs, I receive their payment minus admin & transaction fees (~3.25%-4.5%). Your fees are lower, and rental prices slightly better (from my perspective), so I'd love to switch services. However, I'm unwilling to get jerked around like that. $20k in hardware needs to earn back it's investment every hour of everyday. You shouldn't be acting as a middleman for the funds, as it makes you liable to both parties over financial issues.

I mean, the moment someone rents out my rig, they are taking away income from somewhere else. They should be required to fulfill that contract, which is enforced by full and upfront payment. I both rent my rig, and have rented rigs from others. I routinely peruse the feedback threads of other providers to see what everyone else's experiences are like. I've never encountered a provider who had a problem on his end and didn't over compensate or refund his client. I usually provide anywhere from 15-25% bonus on lost hashing power when there is problem on my end. I've even seen providers compensate for problems on the clients end, like bad pools. The protection doesn't need to be on the client side. Providers have a vested interested in continually providing good service, as it encourages future business. Clients have no particular need to be a good customer, as they can just change their email address and rerent from someone else, should they feel like being a troublemaker. Thankfully most clients and providers are good, honest people just trying to transact honest business.

Can someone explain to me if there is any reason that I should continue using mining rentals such as leaserig dot net ? I paid 0.06510000 BTC for a 12 hour scrypt rental with testthewhiterabbit using middlecoin as the pool.  At the end of 12 hours I have 0.00374 BTC in mining rewards.  I am trying to determine what if any is the purpose of using leaserig or similar services.  Am I missing something?   By the way, this is my first bitcointalk.org post, but I have been a lurker since 2013.

Thanks

Don't use profit switching pools for rented hash power. I lease out my own rigs, and I always keep some margin above the coin switching pools, because otherwise I'd just mine from the coin switching pool. In fact, that's where most of these rigs are mining when you *aren't* renting them. The leasing website takes a 3% cut out of whatever you pay us on top of everything else, so we have to account for that in our pricing. Rented hash power is good for profit opportunities like new coins, double rewards etc. For instance, though I lease my own rigs out, I disabled that and even rented 3 other rigs when ghash started their double rewards (before they screwed it up). I made a 12-15% over what I paid the rig owners when it was all said and done.  Wink

Sorry, new feature development is now stopped until some people think about how much work time I spent on it.

Good f'ing luck with that.  Roll Eyes

You are barking up the *wrong* community if you think the tightwads in this joint will part with even a single satoshi if they can get it or something similar for free. That's not true of everyone here, but it definitely was my experience.

Seems like there is some sort of allergy or moral opposition to actually sending donations for mining/monitoring software around here.

Try building in an option for donation mining, that might have better luck.

Advertising a software product as free, and requesting donations as payment rarely results in you feeling truly compensated for your work; particularly in this industry. Getting mad because people aren't donating what you feel your software is worth kinda proves that you chose the wrong model.

Alternatively, convert what you have into a paid or ad supported product. Leave the existing product exactly as it is, offer an updated one via a private repo to people who 'donate'.  Smiley

Consider doing something (e.g. Mining), instead of nothing (e.g. Bot Day trading) to earn your money.

Also, opportunities to leach money out of the alt-coin economy via "ping-pong" are fewer and far between, when most currencies are trending downward at the same time.

Truly, I get a warm and fuzzy feeling inside whenever someone using one of these bots complains about a net loss.  Smiley

But by all means, please continue. The buy orders these bots are placing are paying plenty of Miner's electric bills. Meanwhile, smarter speculators recognize what these bots are doing, and are getting better at exploiting them & extracting profit from you. Watch the troll box in the exchange once in a while, you'll understand eventually.

You know, the other interesting thing about payments via Crypto/Wire/ACH? They are non-reversible. There is zero payer side protection.

You have no actual pictures of your hardware (aside from obviously photoshopped images of someone else's stock products with a bad blur filter applied, and your logo pasted on).

Completely unrealistic power numbers with buzz words like '28nm process' thrown in.

Smells like bullshit to me.  Angry
