[Work in progess] Burnins Avalon Chip to mining board service

[Bogart]

Here is a simple script to put in cron.

Code:

#!/bin/sh
#
if pgrep cgminer > /dev/null
then
logger "cgminer up"
else
logger "** cgminer down"
logger "** Starting cgminer"
screen -dmS cgminer /home/cgminer/cgstart.ksh
fi

That's handy, but in my case cgminer was still running.  It had just stopped talking to the bitburner for some reason.

I actually run my cgminer in this little script:

Code:

#!/usr/bin/perl

while (1) {
        system( "/home/user/bin/cgminer/cgminer --avalon-auto --avalon-freq 350-450 --more --args --here" );
        print "Sleeping 5s before restart...\n";
        sleep 5;
}

I know, using perl is overkill, but I'm a perl guy.

Then I have rc.local start the above script in a detached screen session at boot-time.

I wasn't watching it.  Is there an easy way to send the output to a logfile?

/home/pi/bin/cgminer/cgminer --avalon-auto --avalon-freq 350-450 --avalon-options 115200:2:10:d:350 --failover-only --api-listen --api-allow W:192.168.23.0/24 2> file.log

Also --failover-only means that if the stratum pool says it is still connected but it isn't providing work properly you may indeed not get work to give to the BTB
I'm not sure why that can happen, but I've seen it on a stratum pool that was having trouble but not losing the connection

Oh I just checked, my previous was Runtime: 71 hrs : 36 mins : 16 secs
(until I did a code restart)
[2013-09-17 16:38:38] BTB0 42C/ 42C 0000R | (5s):5.742G (avg):6.956Gh/s | A:416626 R:3442 HW:19 WU:97.2/m

Heh I just noticed that looks like a minor bug in the final summary report

Hmm I seem to get a crash every day now.. , any way I can help debug this issue or provide info for the devs?

Mine crashes like every 30 hrs or so. I just make sure to restart cgminer every morning when I grab my coffee. It doesn't matter if it's one burnin miner or 32 plugged into the system. I just figured it wasn't much of a hassle so I didn't bother posting this.

I get about 48 hours before mine crashes. Running cgminer 3.4.2

Hey burnin or someone else i was wondering if there could be something to screw at the bottom of the bitburner boards? I don't know what is the word for the long steel stuff that holds the boards together and while they seem to be pretty stable i thought maybe i could improve that.

My test-stack of 16 boards has now an uptime of ~2 Weeks without cgminer restart.
But i am using a rather old version of cgminer.

btw: news in the B'Fury thread: https://bitcointalk.org/index.php?topic=283992

Shipping of Batch 2 is under way, i am too busy to put in tracking numbers (will add them later).

[vanycon]

Hey burnin when do you start building the avalon miners from the recieved batch?

Do you wait till the last avalons arrived or did you even start... time is BTC u know

And btw I send you an email cause my chip distributor changed a little bit hope you recieved it and that should not a big deal

Ok, but what to i put on the floor in order to have better stability?

I took Sebastians chips to my contractor yesterday was able to get a time-slot on the machine right away. (unlike Zefir Batch 2 where i had to wait)
That time-slot ends later today, with a little luck all boards will be done with smt assembly then.

You could use a thick steel plate as base for the boards in which you screw the standoffs.
Other possibility: lay the stack down sideways.

Still waiting for Zefir batch 2 boards...  
Maybe SebastianJu's batch Shops before?

Thx, burnin said its on the way...

Burnin,

I had an order placed for assembly of 6 out of the 12 Bitburners I had planned on ordering from you. This week I converted that order of 6 to Bitfury boards. However, now that Zefirs chips have finally arrived today, I tried to purchase assembly for 12 Bitburner XX boards today, but Paypal says there is an issue with your merchant account. Please help me out here, I have 240 chips that are en route to you as we speak and Paypal is my only method of payment available at the moment. I understand that you are incredibly busy, but now that the chips are here, I would like to pay for assembly and express shipping. Please let me know what the situation is, thanks.

Burnin,

Over a week ago I sent a PM to you asking for a refund for my order.  After receiving no reply I sent a message through your website again asking for confirmation of the refund and amounts.

I haven't received a reply to that email either.  Can you please confirm my refund is being processed or reply to 1 of my messages?

Regards,

Only Burnin can answer, of course, but my suspicion is that so many people slammed PayPal for refunds when the chips were late, that Paypal froze/closed his account.

Well, some kind of update or communication would be appreciated.

I have a batch 2 order - but the order status on burninmining.com says 'processing'.  Does anyone else have a different status?
Is he actually updating info on that site any more?
I've received no email updates regarding the order.

I guess we have to wait for the post man to ring.

Ah, this is how it works?

Could I get mine too, please?

[SebastianJu]

@burnin... maybe you can push the bitfurys to higher clockrates too since marto got his 16chip board stable to run at 500mhz. Someone said its because the power supply is the same for both boards so that 16 chips can get more wattage than 20 chips. Maybe its worth testing this out to find out the real hashrate of bitfurys too.
