Two new USB stick ASICs are arriving stateside and into the hands of many miners. One is the AntMiner U1, a 1.6 Gh/s USB ASIC from BITMAINtech. The other is Ice Fury, a 2 Gh/s USB ASIC based on the Open Source NanoFury design.
I am currently working on code for bfgminer to allow mining with the AntMiner U1 and will cover that in a future article. For now we’ll focus on the Ice Fury ASIC and what it takes to get these little devices mining under Mac OS X.
As you can see the manufacturers chose to go with a striking white design and a matching silver heat sink.
As with both the HashBuster Micro and the Twinfury, Ice Fury is currently only supported by bfgminer. So, the first step is to install bfgminer on OS X. There is a thread here on the Bitcoin Talk forums which discusses various ways to install bfgminer on Mac OS X. The most full-proof method is to use Homebrew:
- Launch Terminal.app from Spotlight or your Applications folder
- Install Homebrew by entering the following in the command prompt:
ruby -e "$(curl -fsSL https://raw.github.com/mxcl/homebrew/go/install)"
- Run the following command and then fix any reported issues:
- Tap the following Homebrew repository so that you can install packages from it:
brew tap nwoolls/xgminer
- Finally, install either cgminer or bfgminer:
brew install bfgminer
Like the HashBuster Micro and Twinfury, the Ice Fury USB ASIC requires no installed kernel extension or driver.
After bfgminer is installed you can use the -d? argument to list available devices with bfgminer:
[2014-01-07 20:14:16] Started bfgminer 3.9.0
[2014-01-07 20:14:17] Devices detected:
[2014-01-07 20:14:17] NanoFury NF1 v0.7 by Microchip Technology Inc. (driver=nanofury; procs=1; serial=0000096175; path=USB_04d8_00de_3a200000)
1 devices listed
Once the Ice Fury stick is detected you can start bfgminer using the -o, -u and -p arguments to begin mining:
bfgminer -o hostname -u username -p password
If you have any questions feel free to post them in the comments below or on this thread at the Bitcoin Talk forums. Happy mining!
