21  Bitcoin / Mining support / Blackarrow BifuryX16 boards hosted by Beaglebone, Possible? (.25BTC bounty) on: May 31, 2014, 07:32:45 PM
Does anyone know if a driver exists that can do this.  The one based on chainminer (driver-bab.c) for Cgminer,  Seems to be Raspberry pi only.

The Beaglebone looks better suited for controlling 20+ boards due to it's faster CPU.

If I match the SPI pins from the controller to the beaglebone, I think just a proper driver might do it.

Maybe?

Edit: Been trying to get this to work. No go, I am simply not a programmer. I will offer .25BTC to who ever modifies the driver to work.  Or posts information in this thread that

leads to a working setup.  The information would have to be very specific to Blackarrow bitfury boards working with a Beaglebone black. I can provide detailed info on my

configuration.

I have CGminer 4.3.4 compiled in minepeon for Beaglebone black.  The bab driver and bfsc (BFL singles) are added.  I have a V2 controller and 20 cards.

I followed instructions here:http://elinux.org/BeagleBone_Black_Enable_SPIDEV to enable the SPI01 interface.  I also mapped the pins from the Beaglebone to the

cable connecting the the V2 controller card. Used these diagrams:

22  Bitcoin / Mining speculation / Block erupter blade profitablility? on: April 27, 2014, 07:46:23 PM
Could these be made profitable again through underclocking?  Say, installing an 8Mhz crystal to operate at a slower speed. (8x28x32=7168Mhs)

I have a few of these that I turned off recently.   I am thinking about putting them back online and underclocking them for reduced power usage.

anyone tried this?  If I could get them under 4W/Gh it might be worth it. Wink
23  Economy / Computer hardware / [WTB] Looking for BFL singles again. on: April 26, 2014, 12:37:43 PM
Want to buy bfl singles.  Paying comparable GH/BTC as antminer S1's. Post here with offers or PM me.  

I'll pay escrow fees through Ognasty.  Let me know on shipping.  Might pay that too.  I am located on east cost, US.

Only interested in singles that are complete (have all parts except crappy power brick).  Ones with early heatpipe heatsinks preferred.

Thanks!

Post here if you did business with me.
25  Bitcoin / Mining support / I installed BFGminer 3.10 on my Antminer S1, now what? on: January 22, 2014, 07:16:46 AM
Now that BFGminer supports the U1 Ant USB miners I figured I would try installing it on my OpenWRT powered ant S1.

Actually got it to run using screen.  It does not detect the ASICs when I do add or scan.  I did terminate CGminer first. 

What do? Huh

Would be neat to use BFGminer through a putty window and not deal with the built in web interface.

Anybody tried this?
26  Economy / Computer hardware / [WTB] BFL Little singles/Singles on: January 08, 2014, 01:49:16 AM
Buying little singles/singles for between .20BTC and .45BTC as well.  Let me know if interested.

Offering prices comparable/slightly better per Ghs that Antminer S1 rigs.  These sell for 1.45Btc per 180Ghs now.

I will pay escrow. You pay shipping.  International sellers only if you can provide guaranteed 2 day shipping to east coast US.

Thanks! Smiley

27  Bitcoin / Mining support / High CPU usage in Windows 7 With CGminer and 58 Block erupters on: November 11, 2013, 07:30:03 AM
Title says it all.  Have intermittent 40-60% cpu usage while mining using CGminer 3.8.1.  Using the Winusb driver and 58 block erupters.

Also the erupters occasionally seem to be "stalling" or waiting for work (green led lights up for about 2-3 seconds).  I isolated the cpu usage to the plug

and play service.  Maybe this is just USB overhead?  Kinda makes sense with 58 erupters. Roll Eyes  Computer is a Core 2 duo 3Ghz with 4Gb ram.  Machine

acts as a file server and mines, nothing else.
28  Bitcoin / Mining / Whats going on with Bitcoin hashrate? on: November 09, 2013, 06:32:50 PM
Seems to have gone flat, as in very little increase for at least 5 days. Huh

https://blockchain.info/charts/hash-rate

This site shows a less than 3% increase at next diff change.

I might be a bit quick to estimate, but have we hit a plateau?  Have asic manufactures started seriously slowing down production?

Opinions?

Edit: Looks like it's back on track today!

5Ph! Shocked Shocked
29  Bitcoin / Mining support / splitting block erupters into groups on: November 04, 2013, 04:05:45 AM
Might be a dumb question but here goes. Grin

I have about 100 erupters, want only 50 to show in a window.  All are connected to the same computer (Win 7 x64).  Using cgminer 3.6.6.

Reason for this is I use these to mine smaller SHA256 alts.  This way I can mine two coins at once.  Banks of many erupters seem to keep up with fast

coins quite well, if set up correctly.  Thought it could be done by specifying com port range in config  but winusb driver does not seem to assign com

ports to erupters.
30  Alternate cryptocurrencies / Mining (Altcoins) / Frankocoin - Anybody still mine this? on: May 20, 2013, 05:35:25 AM
I was mining it and seems that two blockchains exist.  One ia about 400 ahead of the other, i'm on the older one.

Current block is 26345.  Whats goin on?
