Limited direct sales are also available; contact kalahn@gekkoscience.com for information.

=================
=Expected Performance=
=================
The expected performance of the NewPac is about 0.228 * MHz = GH.  
At the default frequency of 100MHz, the NewPac runs at 22.8 GH.

Rough power usage and efficiency of a NewPac:



The expected performance of the R606 is about 1.368 * MHz = GH.  
At the default frequency of 400MHz, the R606 runs at 547.2 GH.





=================
=How to Run=
=================
At the moment, you will need to a build of cgminer with the latest gekko driver to mine with the NewPac / R606.

The driver is under active development in an fork of ckolivas/cgminer.  
A pull request will be redirected to the ckolivas/cgminer repo once the code approached a stable point.

Run syntax:

Mac OSX Compiling with Homebrew (NewPac Only / R606 support on the way)

    El Capitan (10.11.6)

Code:
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew doctor
brew tap vthoang/cgminer
brew install cgminer


=================
=Cooling=
=================
If you run a stick miner, use a cooling fan.  
 
Increased cooling can reduce the chip's overall power usage.

Non cooled sticks are subject to thermal runaway where heat will trigger increased amperage draw increasing heat in a cycle until the unit fails.

===============
=Basic Q&A / Troubleshooting=
===============

Q. How can I set a different frequency for the R606 vs NewPac vs 2Pac vs the Compac?

cgminer will accept a custom frequency per device type.
--gekko-r606-freq 600 --gekko-newpac-freq 200 --gekko-compac-freq 200 --gekko-2pac-freq 150

Q. Does the NewPac/R606 support AsicBoost.

Mostly.  
  • If you receive shared rejected messages from a specific pool, you can disable asicboost with "--gekko-noboost".

AsicBoost on Win10 may not always work.  
  • If you see the frequency drop as soon as it starts up, you can use a modified version of AsicBoost "--gekko-lowboost" or disable asicboost with the command above.

Q: What is causes message: "make: *** No targets specified and no makefile found.  Stop."

Generated by a failure in the autogen command.   Read the last few outputted lines from the command before make.
Generally seen when running make after running the autogen line with a zero instead of a "O" capital o.

Q. How to get past "USB init, open device failed" ... "you don't have privilege to access" error.
Code:
cd ~/git/vthoang/cgminer/
sudo usermod -G plugdev -a `whoami`
sudo cp 01-cgminer.rules /etc/udev/rules.d/
sudo reboot

Q. How to get past "failed to initialse (incorrect device?)" error.

Generally seen when another driver has a hold on the device.

Q. Something doesn't look correct..  

Here are some of the more common ways to address issue(s):
  • Isolate to test only the usb stick
            Remove any usb extension cables.
            Try a single device without any other accessories drawing power (usb fan, other miners).
            Plug into a into different computer.
  • Check for and git the latest build of cgminer.
  • Look through the README.txt file for relevant notes.
  • Handling problems in Windows:
            Switch to linux Ubuntu or Raspbian.
            Enable High Performance in Power Options Setting.
            Confirm the WinUSB driver is attached to the device.
            Reboot the computer.
            Try one cgminer process per device with "--usb :1".
  • Search for / post the details to this thread.

=================
=Thanks To The Community=
=================

Woot!  A big Thanks for the continued community support.  
These little miner's continued advancements forward can't happen without it.






--
What the port face looks like. We've got USB-A for 5V power out, and a mini USB for control. 12V can be drawn from either a PCIe 6-pin jack or a 2.1/5.5mm barrel jack (for running off a brick). The blue knob is used to adjust core voltage from about 0.63 to 0.80V chip-level, basically the same range as the 2Pac. It can be assembled with a vertical (pictured) or right-angle (front-facing) adjuster.

This guy has an onboard microcontroller that handles fan speed via PWM, detects "ZOMBIE" condition and resets the chips automatically, and will overtemp-shutdown at 80C (to restart mining below 70C).

It's a 100mm square sitting on rubber feet, but there are M3 screwholes at each corner for stacking or mounting in a case.

This miner is built with 8x BM1384 hashing chips. I will be using this form-factor as a standard going forward, so newer versions with better chips will be physically compatible.

For all you flashy-light enthusiasts, it's got a base blue LED and blinks white with returned shares.

With the default settings, this miner should produce 66Gh/s @150MHz.  more details



4  Bitcoin / Development & Technical Discussion / PowerShell and Bitcoin Core on: June 20, 2017, 02:45:00 AM
Just sharing a few PowerShell commands that I recently worked out which may come in handy when working with your wallet in windows.

This requires PowerShell 5.0 for access to ConvertFrom-Json.

Code:
set-alias bitcoin-cli "C:\Program Files\Bitcoin\daemon\bitcoin-cli.exe"

#dump balance
bitcoin-cli listaddressgroupings | convertfrom-json | % { foreach ($group in $_) { foreach ($addr in $group) { write-host "$($addr[1])`t$($addr[0])`t($($addr[2]))" } } }

#dump keys*
bitcoin-cli listaddressgroupings | convertfrom-json | % { foreach ($group in $_) { foreach ($addr in $group) { $privkey = bitcoin-cli dumpprivkey $addr[0]; write-host "$($addr[0])`t$($privkey)`t($($addr[2]))" } } }


*as needed
Code:
#unlock for 60 seconds
bitcoin-cli walletpassphrase "my pass phrase" 60

=================
=Expected Performance=
=================
The expected performance of the 2Pac is 0.11*MHz=GH.  For example, 150MHz gives 16.5 GH (theoretical expectation).

Rough chart of power draw:


2Pac running with default settings:


=================
=Cooling=
=================
If you run the miners over about 100MHz it is strongly advised to cool them with a fan.  The cooling requirements are fairly low and unless you're trying to run 250MHz or above almost any fan at all will do.

===============
=Basic Q&A / Troubleshooting=
===============

Q. Can I run this cgminer build with the original Compac?

Yes.  The original Compac will register with separate device name from the 2Pac.

Q. Can I run this cgminer build with other USB miners?

It is recommended to use the official cgminer build for better support of other devices.  
It is best to keep the 2Pac separated from other devices until this fork of cgminer can be regression tested.

Q. How can I set a different frequency for the 2Pac vs the Compac?

cgminer will accept one or both parameters for the stick.
--gekko-compac-freq 200 --gekko-2pac-freq 150

Q. How many 2Pac(s) can I run at a time?

One.  Review the power chart in the performance section above.  
You can add more sticks using a 1-2A per port powered hub (recommended).
Hub thread: https://bitcointalk.org/index.php?topic=1779423.0

Q. Something doesn't look correct..  

Here are some of the more common ways to address issue(s):

Any email asking for support will be met with "If you didn't buy from me, talk to the person you bought it from."


Q. How do I get the latest version of the driver and code?

Updates to main cgminer and gekko updates will be checked in regularly.
If you are following along with the instructions, enter the cgminer directory, pull and rebuild:
Code:
cd ~/git/vthoang/cgminer/
git pull
...


Q. I tried the latest code and am certain the old one works better, how do I go back?

Code:
git reset --hard 495461c
CFLAGS="-O2" ./autogen.sh --enable-gekko
make -j 2


Q. How to get past "USB init, open device failed" ... "you don't have privilege to access" error.
Code:
cd ~/git/vthoang/cgminer/
sudo usermod -G plugdev -a `whoami`
sudo cp 01-cgminer.rules /etc/udev/rules.d/

7  Bitcoin / Pools / CKPool Stats - iPhone App on: January 28, 2016, 06:50:53 PM
Apple iPhone version for CKPool Stats is now available

This is the main thread to provide status and QA.  

Related Threads:
https://bitcointalk.org/index.php?topic=789369.0 kano.is
https://bitcointalk.org/index.php?topic=763510.0 solo.ckpool.org

CKPool Stats provides a portable view of key statistics from kano.is and solo.ckpool.org.

Current Release v1.2 adds:
- Worker transition to idle notification.
- Worker sorting by name / hash tapping.
- Badge notification for idle workers.
- api key QR reader.  

Release v1.1 included support for:
- Block solve / found notification.
- Payout notification (kano.is).
- Apple watch notification when paired.
- Pool statistics.
- API based worker statistics (kano.is).
- BTC address worker statistics.

https://itunes.apple.com/us/app/ckpool-stats/id1076177533?ls=1&mt=8



Troubleshooting steps:
1. Make sure you have internet access.
2. Make sure you allow notifications (do it right the first time).
3. Kano.is username(s) are case sensitive.

FAQ:
Q. There's a red badge on my icon with a number in it.  What is it and how do i clear it?
A. The number represents the count of idle workers seen in your watch list.   It will clear itself out when idle workers clear out.

Q.  How do I sort my workers by hashrate?
A.  Tap the hashrate of any worker.   It will sort ascending (yellow).  A second tap on the hashrate will sort descending (green).  Same applies to worker name.

Q. What is Direct Addresses?
A. That plus sign in configuration is for adding BTC based worker monitoring addresses.   It will be listed under Direct Addresses.
        1. use address.worker syntax (address only might work)
        2. swipe the added item to the left to get the option to delete typos.

Q.  What is the criteria for Trending Down?
A.  Subject to change: Trending Down is currently set to show worker where its 5 min hash is less than 85% of it's 24h hash.

Q.  The app link is reporting not available in my country.
A.  Try again in later.

Q.  Can I join beta to get a sneak peek at the next build.
A.  PM me an email.   You'll get added to apple's beta list for new build notification and early install.  


Known Bugs:
- Two stats pool mode covers up marquee on iPad mini.
  + Cleaned up in next build.    Workaround: Use four stats mode.


What's next in v1.3:
1.  Worker detail modal.
2.  More on/off buttons in the configuration section to customize.
3.  One or more misc todo.


Misc Todos:
1.  Summary group for DA
2.  iPad friendly(er)
3.  Multiple account support.
4.  Add worker name which found block.  (best effort)

Disclaimer:
