Hi Merratzz, probably I found the bug on mastermining.net.

The problem is that: I change the password but didn't got anything by email. I've been trying to repeat this procedure several times, with no result. No email arrived.
Could you please check the mechanism of "password remaining" and "email sending". 

Thanks!

PS. Can't find any contact or support info on the website.

I gave address to my partner about a year ago. Can he/she make transaction on this address?

Is it possible to generate several addresses for future (year or several years later) usage? Is there any limitation of lifespan for BTC addresses?

thanks

Hi technobit,

HEX4M boards with Coolers, Item No.: 97 was oredered on  7 Feb 2015
Order reference: YKHOBUKVB
Status: Payment accepted

Have no email confirmation received, just PayPal receipt. Money was transfered.
The order successfully displaying in my Order history.

72 hours shipping declared on the website, but still nothing received.

2 days ago I wrote the letter to customer cupport via the website form... still have no answer as well.

Almost 2 weeks are gone. No emails no parcels.

Would be appreciate for comments and email contacting.
thank you.

Does the miner display Accepted message when it
a) receive the data for computing the hash summ?
or
b) send the hash summ to the server and server accept it?

Hi all,

where is testing.ckpool.org by the way?
Would be great to have one for named purposes.

(there is mistake above, I mean ... _decrease_ prevetively the minimum difficultiy....)

Probably my explanation was not enough correct.  I'm using quite weak Avalon Nano. And Rejections looks like ... Rejected .... (Above target). All of them has relatively low difficulty (<10), but some shares are Accepted (very rare) and the difficulty of accepted shares is significantly higher (>1k). I just suspect that I need to inform pool that I have weak hardware and need less difficult blocks or more time for calculation (in the same way as it done in classical pools with worker minimum difficulty). Or my understanding of mechanism is wrong?

Another problem that Avalon Nano decreasing the speed in minutes to 0, as a workaround I need to restart it with the bash script periodically. So if the pool have any mechanism for difficulties adjustment, it doesn't work in my case as well

I'm trying to run solo via the http://solo.ckpool.org/ but however just a tiny fraction of shares are accepted. Is it possible to increase prevetively the minimum difficultiy form my (miner) side? I see the +diff option was named above. However I can't fid any relevant information regarding this option. How can  I use it with my USER(i.e. BTC address) parameter?

I'm using bfgminer, if it have a sense to mention.

Thank you!

Hi there!

this is the question to Technobit. Why you folks newer answer on messages posted via your website form. I've been trying 3 times. All of them was unsuccessfull. And this is only contact that clients can find on your website.

What the best method of communication for you? do you have any public email I (and other clients) can write to be sure that I'll get answer?

And my questions:
1. is it possible to pay via bank transfer?
2. can you provide invoice for the item?

Thank you.

irrelevant

actually, not. I use classical stratum "single" pool.
But... concerning to your issue, does your hashrate drops to 0 or just getting relatively lower? Cause mine drops to zero.
(and I was trying it on ver 5.0 as well, by the way)

Hi,

I've got number of the Avalon Nano (https://bitcointalk.org/index.php?topic=779612.msg8841428;topicseen#msg8841428) and have successfuly downloaded and compiled fresh version of bfgminer and run it. It works fine for couple of minutes, then it starts to get slower and finally stall at all. Restarting the bfgminer helps but for same couple of minutes.

I've got configuration here: https://en.bitcoin.it/wiki/Avalon_nano#BFGMiner
here is a log (last half of that): http://pastebin.com/EQAj58HH

The obvious solution -- to make the simple script that restart BFGMiner each 2 minutes, but it's doesn't looks good.

Would be appreciate for any help and hints!

PS I'm on linux (if it may concern...)

Hi all,

I've got number of the Avalon Nano (https://bitcointalk.org/index.php?topic=779612.msg8841428;topicseen#msg8841428). I have successfuly downloaded and compiled fresh version of cgminer
https://en.bitcoin.it/wiki/Avalon_nano#Cgminer_for_Avalon_nano

but ir can't detect devices whatever i did. I was trying
several versions including lastone from here
https://github.com/Canaan-Creative/cgminer/tree/avalon-usb
with and without the "--with-system-libusb" option

Would be appreciate for help and hints.

PS. bfgminer detects devices just fine and start hashing, but there another problem... it stall in minutes and need to be restarted. So my hopes targeted to cgminer.

I'm *NIX user (if it may concern...)

thank you for hint, but
I don't use proprietary software. And don't reccomend to do so for anybody, especially who have a deal with cryptocurrecy.
I'm *nix user. So ehash.com MS Windows app just irrelevant in my case.
I don't need GUI for my purposes

Hi,

I just recentyl purchased the Avalon Nano (anonced here couple of month ago https://bitcointalk.org/index.php?topic=779612.msg8841428;topicseen#msg8841428). I have successfuly downloaded and compiled fresh version of bfgminer and run it. It works fine for couple of minutes, then it starts to get slower and finally stall at all. Restarting the bfgminer helps but for same couple of minutes.

I'd be appreciate for any help.

PS cgminer just doesn't work at all. can't detect devices. I was trying several versions including lastone.

By the way, guys, why just don't use some sort of FTDI  USB-SPI converter instead of RPi?

http://www.ftdichip.com/Products/ICs/FT221X.html
or this monster (that I have) http://www.ftdichip.com/Products/ICs/FT2232H.htm

Hi!

is it really necessary to have level translator for RPi connection? why nobody mention it before (or I miss something?)

Does anybody know whether Bitmine have any plans to reduce prices for Coincraft samples? Difficulty have risen dramatically since February and in the measure of price/watt ratio it looks like almost 0 profitability. Even in good market prognosis.

NB. I remember here was somebody form Bitmine co-owners?

nice job!
could you show assembled board? both sides? would be interesting to see your cooling solution.

извините, а куда делся пост про LPC на Лепре?

good news! looking forward...
