1  Economy / Computer hardware / 2 x Bitmain S7's for sale on: April 24, 2018, 07:58:10 PM
As the title suggests, I have a pair of working S7's I've decided to stop mining with - they are my last pair and very likely my exit from mining.

Looking around the site, looks like an S7 is going for about $200?  I'll take $200 ea plus shipping, will accept LTC, BTC, XMR, XRP.  These are working miners in a climate controlled DC.

I'm willing to do escrow with a trusted member, but you pay any escrow fees and set it up.  I can provide pics if you really want, but you know what they look like.

Forgot to mention, shipping from Wisconsin, USA

Open to offers...
2  Economy / Computer hardware / Various S9 and L3 units available for sell on: February 13, 2018, 11:29:14 PM
Through a family contact with business relationship (which, yea - I know sounds shady) I was asked to see if there was interest in some S9 and L3+ units.

  • S9 13.5T in stock, price: $2980 , delivery in hongkong , not include psu.   350 pcs in stock
  • S9 14T in stock , price: $3360 , delivery in shenzhen ,not include psu.    80 pcs in stock
  • S9 13.5T delivery in March, price: $2750, delivery in hongkong , not include psu. 600 pcs available
  • S9 13.5T delivery in March, price: $2950 , delivery in shenzhen, included psu .  120 pcs available
  • L3+ delivery in March, price: $1900 ,delivery in hongkong,not include psu.   190 pcs available
  • Original psu price $150/pc.

I'm waiting on the pics for the units that are in stock and will post them as soon as I have them.  Will accept crypto for conversion price based on bitfinex plus 4%.  Shipping extra to your location otherwise pick-up in China is an option?

If the business contact does not provide me pictures before the end of the week, I'll remove this post and apologize for wasting everyone's time.  Escrow an option until I'm told otherwise (in which case I'll remove the post as well - escrow is the only way to go).

let me know if there is interest, there is some price flexibility for multiple units.

-cheers

3  Economy / Computer hardware / [WTB] cointerra psu breakout board on: June 14, 2016, 08:32:34 PM
Looking for a breakout board (or two) from Cointerra, ideally from someone who no longer has a need for the breakout board (the PSUs I have are fine - the board's negative lead fell off).  Might be interested in the PSU as well, but would need a good price on it since I already have 2.

Card is marked as COIN-501-048 REV 1 | COIN-500-048 REV A

If you have one available, let me know how much you want for it.  Shipped to 53005.
4  Economy / Computer hardware / Powered pcie risers on: June 03, 2016, 04:33:20 PM
I've got 15 or so powered risers still in anti-static wrap, never used.  These are the pcie 1x to 16x risers.

$8/ea

I don't have pics right this moment, but can add them later if someone feels it necessary.

Escrow is fine as long as you pay for it.

Check my rep and trust, ask any question you feel relevant.
5  Alternate cryptocurrencies / Altcoin Discussion / GorillaBucks 1st Co-Op GorillaBand Node on: July 03, 2015, 05:23:17 AM
Earlier in the week I posted an offer to host a co-op Gorillaband for the GorillaBucks coin.  I want to keep an open and honest running tally of the results of running a Gorillaband as well as invite discussion into the merits of running a Gorillaband (in comparison to just staking the same 5K coins).

The initial posting for the invitation into the co-op is posted here: https://bitcointalk.org/index.php?topic=1059159.msg11749802#msg11749802

Fortunately we had a few takers, though as of this posting I haven't received authorization to share who the members are.  That said, I would mention that IGotSpots was interested in getting the first co-op off the ground and is invested more than 50% into this particular instance.

I received the last deposit at around 11:40pm (local time) and brought the Gorillaband node online around midnight.  With that said and now that it's active, I'll report back at least daily on the return of the Gorillaband.

If there are any questions regarding this topic, please feel free to ask.

Cheers,
baldpope

7  Other / Beginners & Help / Using different ASICs with the same cgminer instance on: September 30, 2014, 09:24:28 PM
I wanted to start this short thread/tutorial because I like to share documentation when I can.

First, a quick shout-out to the following

  • give-me-coins mining pool - always good people and willing to help - visit them on #give-me-coins on irc.freenode.net
  • cryptomining-blog.com - I can't tell you how many times I've used their site as reference for finding updates - keep up the good work folks

special thanks to the following - everyone should know these guys

  • ckolivas - original author of cgminer - yea it's BTC only but without him (and I'm sure others) mining would still be near impossible for most of us
  • dmaxl - one of the many contributors who have picked up the code for those of us mining altcoins

Recently, I was fortunate enough to pick up some good deals on a couple of Fury and Black Widow miners.  I knew that I didn't want to maintain another 2 hosts trying to manage them independently from the other rigs I have so I attached them to my existing GPU rig.  The following is a brief step-by-step (with some large assumptions for the reader - but please feel free to ask any questions)...

First, we'll need to download, configure and compile the cgminer instance from dmaxl

Quote
mkdir /opt/zues_miner
cd /opt/zues_miner
git clone https://github.com/dmax1/cgminer.git
cd cgminer
./autogen.sh

before proceeding, it's very possible someone will get stuck at this step - you CANNOT proceed until this autogen.sh completes cleanly.  I won't go into detail here, but make sure any dependencies are satisfied before proceeding.

Quote
./configure --enable-scrypt --enable-zeus
make

Once the above completes, you'll be left with your very own instance of cgminer, targeted for use with the Zeus chipset ASICs, in my case the Fury and Black Widow ASIC miners from Gawminers.

Before proceeding, I recommend taking a moment to understand how to identify the correct ASIC miner from another.  I did the following in a control environment so that I knew which device was which. 

  • Make sure only one of the desired ASICs are plugged in and run cgminer --ndev

Quote
./cgminer --ndevs
 [2014-09-30 14:34:51] USB all: found 22 devices - listing known devices
USB dev 0: Bus 2 Device 36 ID: 10c4:ea60
  Manufacturer: 'Silicon Labs'
  Product: 'CP2102 USB to UART Bridge Controller'
  • Take note of the Bus and Device values.  In this case, I plugged in the Black Widow and identified it as Bus 2 and Device 36 (this is relevant for later)
  • Also take note of the vendor ID, in this case 10c4:ea60 - useful for later
  • Now, plug in a second USB device and run cgminer --ndevs again

Quote
./cgminer --ndevs
 [2014-09-30 14:34:51] USB all: found 22 devices - listing known devices
.USB dev 0: Bus 2 Device 36 ID: 10c4:ea60
  Manufacturer: 'Silicon Labs'
  Product: 'CP2102 USB to UART Bridge Controller'
.USB dev 1: Bus 1 Device 48 ID: 10c4:ea60
  Manufacturer: 'Silicon Labs'


You'll notice now that two devices are listed - but the first device still has the same bus and device enumeration.  The second device is located at Bus 1 and Device 48.  I recommend adding each device and taking note of which physical device is plugged into which bus.  Alternatively, if you only have 1 odd device, you can just identify it and move on

When complete, you should be able to run the following:
Quote
mint ~ # lsusb -d 10c4:ea60
Bus 002 Device 036: ID 10c4:ea60 Cygnal Integrated Products, Inc. CP210x UART Bridge / myAVR mySmartUSB light
Bus 001 Device 048: ID 10c4:ea60 Cygnal Integrated Products, Inc. CP210x UART Bridge / myAVR mySmartUSB light
Bus 001 Device 049: ID 10c4:ea60 Cygnal Integrated Products, Inc. CP210x UART Bridge / myAVR mySmartUSB light
Bus 001 Device 054: ID 10c4:ea60 Cygnal Integrated Products, Inc. CP210x UART Bridge / myAVR mySmartUSB light
Bus 001 Device 051: ID 10c4:ea60 Cygnal Integrated Products, Inc. CP210x UART Bridge / myAVR mySmartUSB light
Bus 001 Device 052: ID 10c4:ea60 Cygnal Integrated Products, Inc. CP210x UART Bridge / myAVR mySmartUSB light
Bus 001 Device 053: ID 10c4:ea60 Cygnal Integrated Products, Inc. CP210x UART Bridge / myAVR mySmartUSB light
Bus 001 Device 055: ID 10c4:ea60 Cygnal Integrated Products, Inc. CP210x UART Bridge / myAVR mySmartUSB light

Now with the devices identified, you'll need to launch cgminer with the correct options to address each miner.  As noted above I have both the Fury and Black Widow miners, specifically 10 and 1 of each.

I want to set the global chip count and clock speed for all Zeus Fury miners and then a specific chip count and clock speed for the Black Widow.  I accomplish this by adding the --zeus-options to the cgminer line, along with the Bus and Device ID and with the relevant miner options.

Quote
./cgminer --scrypt --zeus-chips 6 --zeus-clock 340 --zeus-options 2:36,64,328

In the above example, the --zeus-chips and --zeus-clock options are global and apply to any device device not explicitly identified.  Here we are saying that all Zeus chipset ASICs will have 6 chips and operate at a clock speed of 340.  Additionally, we are specifically referencing the miner at Bus 2, Device 36 which will override the defaults and use 64 chips and a clock speed of 328.  In this way, we can run a mix of equipment from the same miner interface.

The resulting cgminer instance shows the devices individually addressed:

As a quick side note - take caution when assigning the clock speeds.  I found that these work for me, but your results will likely vary.[/list]
8  Economy / Reputation / baldpope reputation thread on: February 12, 2014, 07:22:19 AM
I wanted to share a bit of who I am and start a solid reputation here...

I joined the scene only a few short months ago, but have been very active with support over on Freenode.  I started mining to supplement my income, but also to encourage alternate forms of currency.  As a small-business owner, I will be accepting crypto once I have finalized on a check-out service.

I began mining with 3 Gigabyte R9-270X GPUs in mid-December of 2013, and doubled that with an additional 3 Sapphire R9-270X gpus before the end of 2013.

I've built a couple of rigs for myself and have built for sale an open-air-rig adapted from a version here.  Any future sales will result in donations back to the original designer.

I've completed a couple of person-to-person sales of PCIe risers without any fuss.  I've also bought some LTC through Paypal.  In keeping with being a good netizen, I try to extend a level of trust that I would hope is returned to me.

I'm likely in for BTC/LTC for the long haul.  I see value in the block chain, beyond it's existing currency.  I hope to be mining and supporting crypto for years to come...

If we've done business together, or I've assisted you in any way, I appreciate positive endorsement.  If we've crossed paths and somehow got on the wrong side of each other, let me know.  I'm sure any disagreement can be settled.

Cheers,
baldpope
