I'll buy them all for 70 cents on a dollar. Looks like $545 give or take a dollar. How about a nice rond $380?

At that low a rate, I'd just use them myself to buy something at Home Depot.  I'm in there almost on a daily basis.  Just trying to pickup some BTC to add to my stash is all.
It's amazing how hard it is to get BTC otc, instead of having to got thru an exchange.  I'd consider 90%.  You can use a Lowe's 10% off coupon with these store credit cards and get yourself a total of 19% off anything from Home Depot.

How about 80 cents on the dollar? That's my max. I really don't want to give up my BTC either haha.

You pick anything you want from Home Depot.
Pay in BTC.
Get it shipped to your house.
Do we have to pay shipping?

Depends.  I think some stuff has free shipping. I think anything over $50 is free shipping.

BAMT Not working

Downloaded BAMT from :

http://files2.bitcointrading.com/bamt_v0.5c.zip

wrote the image file and tried on 2 different USBs same result, it starts with the firy screen (normal safe mode etc.) than goes to "starting" some lines come on the left side and than nothing. The screen goes blank. Using on a an experimental rig of one 5970. Mobo is 4Core1333-Viiv (Asrock).

Also tried going on safe mode of BAMT but does'nt allow me to go there.

Any advice Huh

thx

sounds like your 5970 is not 100%.  Try with a different gpu.

But works fine with cgminer in win7, overclocked and giving over 700 mh.....?

create another BAMT usb stick with a new stick

No.  network hash is not 175TH. A large portion of the jump is variance.

If you end up needing a Control Unit replacement, I can sell you a clone (based off of Avalon published specs). I will have several of these ready and working in about two weeks. You can try one first, if it doesn't work for you, simply return it. If it works and you want to keep it, just send me back a few Bitcoins. PM me if and when you need it.

Will you have these preflashed with the fpga bitstream?
211  Bitcoin / Hardware / Re: Avalon #2 damaged on: June 06, 2013, 01:12:40 PM
Without an available bitstream for the Avalon, that will be impossible.  The .bit file available is just a test file which blinks the LEDs on the front of the unit.

The real bitstream is available at https://github.com/BitSyncom/avalon-ref/tree/master/FPGA

Thanks mrb.  Hadn't seen that.  I was keeping an eye on http://downloads.qi-hardware.com/people/xiangfu/avalon/fpga-controller/  for the bitstream.  Smiley
212  Bitcoin / Hardware / Re: Avalon #2 damaged on: June 06, 2013, 02:51:30 AM
time to trade in the wife or the Avalon

What sells higher at the moment? The wife would be kind of package deal with kids attached...

Probably depends on the ROI on the kids. There's always a chance that one of the younglings will make it in Hollywood!

Asian kids don't sell for much unfortunately. Too much supply.

I'm an expat - so we are talking about a really scarce good here... I wouldn't mind however if somebody could have a look at the log I've posted and tell me what might be the problem.
Or somebody point me to how to reprogram the FPGA.

That is 2.4 BTC in 24 months, in other words 20%! Thats great! I get 1% at my bank! Loving it!!!

This misunderstanding of how much btc a piece of hardware will generate over a "long" (ie. more than a few months) time is probably the biggest reason people are buying hardware like this.  Good luck getting 2.4 BTC in 24 years.

Anyone with a successful removal of fuse F1, yet?

Yes, I removed it from my Avalon and all appears to be working again. The fuse would not pop completely off the pads but enough of it has been removed to open the circuit. It was more of a cut than a removal. A better soldering station might have helped.

Had you noticed any overheating of the NEC usb hub chip?
215  Economy / Computer hardware / Re: [WTS] - 11 BFL singles, perfect condition, with power bricks on: May 31, 2013, 03:21:05 PM
Bump......have 8 of these left! 

If by discount, do you mean 4BTC each, I'm in.  Only if I get an answer within the next few hours so I can place an upgrade order.  Grin

I'll open it up and take a look this weekend. From what I've read, disabling the wifi interface can prevent overheating the usb interface. I'm using ethernet and never had wifi wnabled in the first place.

disabling the wifi interface will not prevent overheating.

https://github.com/BitSyncom/avalon-ref/issues/5

F1 fuse on the fpga board needs to be removed.
217  Bitcoin / Project Development / Re: BAMT version 0.5 - Easy USB based mining Linux with farm wide management tools on: May 31, 2013, 03:17:18 PM
Anyone know how I fsck on boot?  I tried 'shutdown -F now' and putting a blank forcefsck file in root but it appears this gets skipped on boot.  If I move the USB drive to another machine and fsck it, it works fine... but now my rigs are remote so manually moving the usb stick is not as easy as it used to be.  I figure it might have something to do with the live image partion and I'm putting the forcefsck in the wrong spot but I'm not sure....

why fsck?

coz linux can fail to start if the fs is corrupt?

well.. ok.. i know that, but i kinda meant, instead of fscking, just create a new usb.  In my experience, if the usb file system is corrupt, it's a whole lot easier just dropping a backup copy of the image you were running on a new usb.

Batch #2 do not have a P2 jumper on the fpga controller board.
I have Batch #2 units, and my controller boards do still have a P5 jumper.  It's located just behind the USB type B receptacle.  As shown in this picture.

Ah!.. I seem to remember you had a "silver" case avalon.  I guessing you got the last of the <v1.5 batch#1 leftover parts.
220  Bitcoin / Hardware / Re: Official Avalon Technical Support Thread on: May 29, 2013, 03:12:55 PM
One of my Batch #2 Avalons is having trouble.  Every so often (~15 minutes on average) I get a long burst of these kinds of messages in the System Log (dmesg):

Code:
May 18 06:42:59 avalon1 kern.err kernel: [ 3872.320000] usb 1-1: clear tt 1 (8040) error -71
May 18 06:42:59 avalon1 kern.err kernel: [ 3872.330000] ftdi_sio ttyUSB1: failed to get modem status: -71
May 18 06:42:59 avalon1 kern.err kernel: [ 3872.340000] usb 1-1: clear tt 1 (8040) error -71
May 18 06:42:59 avalon1 kern.err kernel: [ 3872.350000] ftdi_sio ttyUSB1: failed to get modem status: -71
May 18 06:42:59 avalon1 kern.err kernel: [ 3872.350000] usb 1-1: clear tt 1 (8040) error -71
May 18 06:42:59 avalon1 kern.err kernel: [ 3872.460000] ftdi_sio ttyUSB1: failed to get modem status: -32

While that is occuring, all mining stops.  Either it eventually goes back to normal, or I see a message in the System Log saying that ttyUSB1 was disconnected, and then reconnected as ttyUSB0 (and vica-versa).  cgminer dies if that happens, and restarts.

I have another Batch #2 running smoothly.  So far, I have checked all of the connectors on the TP-LINK, PDU, and control unit.  I replaced the PSU, left the cover off, and left the PSU outside of the unit.  No joy.  All of the version numbers match my other Batch #2, so there are no differences in software/firmware.  One odd thing is that I notice mention of a usb hub on the wiki page, but there is no hub inside either of my black Avalons.  Is the hub built into the control unit?

I can only think of two other things to try.  Backup the working Avalon, and flash it to this Avalon, in case there's something weird in the software.  Or, replace the TP-LINK with a RasPi and hope that the control unit isn't at fault.
Check the usb Cable first dude.

If i were you i would remove p5 jumper, use USB powered hub and connect usb cable to batch one unit easiest or to linux PC to check. But first change usb cables and try other ports of internal usb hub if batch2 still has it



Batch #2 do not have a P2 jumper on the fpga controller board.  They also do not have an external USB hub. It appears the v1.5 fpga controller boards in the batch #2 avalons have a renesas usb hub chip included to attempt to account for the usb stability problem with the tp703 See: https://forum.openwrt.org/viewtopic.php?id=39956

If anyone from Avalon reads this thread, could you please provide info on whether something can be changed on the fpga board so that it won't backfeed power on the usb port?  It's been mentioned that attempting to connect the fpga board usb port to a desktop could cause problems since the fpga usb port is still powered.

What do J1 and J2 do?

Is it possible to JTAG firmware/bitstream to the fpga? Instructions?

TIA
