1  Bitcoin / Bitcoin Discussion / Re: I want to Buy beer with my bitcoins but... on: January 16, 2015, 09:25:34 AM
Also paid with bitcoin for beer, cocktails and food a few times. Therefor a slightly off-topic question to those who did as well:

How were tips handled? Often the price is coded into the QR code and - depending on your wallet - can't be changed. Last time I used bitcoin the waiter told me that although they accept BTC, tips in FIAT would be welcome.

Do payment processors have a solution for that?

Just visualised another forming s-curve (or a cascade of such) that might be worth mentioning:

My avalon unit has  the exactly same issue as yours. I'd like to ask if the test firmware posted by xiangfu related to this issue?

I am using firmware 20130419. Unfortunately, I don't recall the previous firmware version I was using.

Prior to the upgrade on May 5, the Avalon unit ran without any problems.

However, after the upgrade, the miner has stopped hashing twice, and the only way to recover is with a cold reset. Is this a know issue?

Cheers!

Are you guys running the avalon over wifi or ethernet? I had similar problems with a bad wifi connection: stopped hashing, no access over wifi. I came across the solution when I tried -and could - connect over ethernet and noticed a pretty bad signal/noise ratio. An interruption of the wifi connection can confuse cgminer completely.

Installing a repeater solved this issue for me and I have a Opetwrt/cgminer uptime of more than 7 days now.
6  Bitcoin / Hardware / Re: Avalon ASIC users thread on: May 13, 2013, 04:41:37 PM

When you reset, somehow, it should go back to default, which is, accordinly to the avalon user guide: 192.168.0.100


Well that worked..almost. I could enter failsafe-mode. Here's the instruction:
--
To get into failsafe mode, power up the device and wait until the LED starts flashing (about 2Hz). Once it starts flashing (within about 4 seconds) then quickly press the button. The LED will then flash much faster and the device will be in failsafe mode.
--

Failsafe IP is 192.168.1.1. I could telnet to the router. I checked

root@(none):/# cat /etc/config/network

config 'interface' 'loopback'
        option 'ifname' 'lo'
        option 'proto' 'static'
        option 'ipaddr' '127.0.0.1'
        option 'netmask' '255.0.0.0'

config 'interface' 'lan'
        option 'ifname' 'eth0'
        option 'type' 'bridge'
        option 'proto' 'static'
        option 'netmask' '255.255.255.0'
        option 'ipaddr' '192.168.0.100'
        option 'gateway' '192.168.0.1'
        option 'dns' '8.8.8.8'

Everything seems fine. Anyway, after rebooting I'm not able to ping or ssh 192.168.0.100.

Edit: Fixed it!
After making the filesystem writeable with "mount_root" /etc/config/network looked differently:

config interface 'lan'
        option ifname 'eth0'
        option type 'bridge'
        option proto 'static'
        option ipaddr '192.168.0.100'
        option dns '8.8.8.8'
        option gateway '192.168.0.101'
        option netmask '0.0.0.0'

Changed it. Reboot. Problem solved.
(And back to my original problem. Will probably talk about that later..)

Thanks for your great and fast help!

you cant reach the router.
the avalon is still there, conect it to your PC with cgminer installed via USB, asap, then you think about repairing/reseting the router.

Thanks for that quick answer! I have to install cgminer first on my Laptop...
Can the router be reset by the small button? How? What IP does it have afterwards? Will I be able to flash it again with the latest custom firmware?

Really appreciate your help.

While trying to solve some networking problems on my avalon I made it even worse Sad

Connected via LAN disabled WLAN, later I set the LAN subnet to 0.0.0.0. IP address is still 192.168.0.100. Now I can't reach it anymore. Is there a way to reach it again?
9  Bitcoin / Hardware / Re: Avalon ASIC users thread on: April 16, 2013, 08:36:50 PM
Thanks for your help guys.
Opened it and checked the cables. Everything seems to be connected. Although I wanted it to run for some hours, cgminer restarted half an hour before. But anyway, same picture:

[Elapsed] => 2105
   [MHS av] => 64931.87
   [Found Blocks] => 0
   [Getworks] => 84
   [Accepted] => 499
   [Rejected] => 1
   [Hardware Errors] => 26
   [Utility] => 14.22

Temp1: 26
Temp3: 47

Ambient temperature is about 23°C.

Can anyone tell me, if these are normal values for the avalon. HW error seems still pretty high. Updated to 20130410 (next-testing) firmware recently. Cgminer runs at 282M(Advance):

  • => SUMMARY
[Elapsed] => 41011
   [MHS av] => 67092.46
   [Found Blocks] => 0
   [Getworks] => 1495
   [Accepted] => 9909
   [Rejected] => 52
   [Hardware Errors] => 827
   [Utility] => 14.50
   [Discarded] => 2785
   [Stale] => 0
   [Get Failures] => 0

Can there be anything else done? Am I loosing lots of coins due to that high error-rate?
11  Bitcoin / Hardware / Re: Avalon ASIC users thread on: April 10, 2013, 01:48:52 PM

new firmware build posted. fixes the delay and HW errors and rejects.

http://downloads.qi-hardware.com/people/xiangfu/avalon/next-testing/

Will it be worth to install the test-firmware? Do those HW-errors have a big negative effect?
I'm afraid of getting a worse bug by unstable firmware.
12  Bitcoin / Hardware / Re: Avalon ASIC users thread on: April 10, 2013, 01:21:18 PM
Hi there

I have a HW error rate of about 5% (relativ to accepted) which seems to be rather high.

What can there be done against that apart from setting --avalon-options xxxxxx:xx:xx:42:xxx instead of xxxxxx:xx:xx:45:xx because this seemed to have no effect.

I haven't changed any other parameters, the batch 1 miner runs like it came out of the box.

Thanks

Here's why I can't post.
So let's start.
