Another new ASIC is hitting the streets based on the same 55nm Bitfury ASIC chip found in the Blue & Red Fury USB sticks. This new board, known as the HashBuster Micro, packs nine of the chips found on the Bitfury USB sticks, clocking in at around 23 Gh/s once it is setup and hashing. And, like the previous ASICs I’ve looked at, with a small amount of work is is a wonderful Bitcoin hasher under Mac OS X.
The HashBuster Micro board is available from HashBuster.com for 1 BTC, but is currently sold out. You can also purchase them from the Eligius mining pool store. They are 0.86 BTC and ship very quickly (I had mine in four days).
Now this may either be a turn off or a draw for you, but either way: the HashBuster Micro does require a small amount of hardware DIY before it will be ready to mine. What comes in the box is the PCB board, a barrel plug for power (with bare wires at the end), and a USB cable. There is no fan, no heat-sinks, and you will need to work out how to get power to the board. Here is the board as it comes in the box:
So you’ll want to purchase at least one 80mm fan, either a single CPU heat sink or a pack of mosfet head sinks, and a 12 volt, 5 amp power brick (if you do not have one). Here’s a quick order list from Amazon:
Unlike the ASICMINER Block Erupters and Red/Blue Fury USB sticks, the HashBuster Micro is currently only supported by bfgminer. So, the first step is to install bfgminer on OS X. There are several ways to go about this, from compiling bfgminer yourself, to using Homebrew, to downloading a precompiled binary.
- Launch Terminal.app from Spotlight or from your Applications folder
- Install Homebrew by entering the following command:
ruby -e "$(curl -fsSL https://raw.github.com/mxcl/homebrew/go/install)"
- Run the following command and fix any reported issues:
- Tap this Homebrew repostory so that you can install packages from it:
brew tap nwoolls/xgminer
- Finally, install either cgminer or bfgminer:
brew install bfgminer
If you’d like to install the miner using the latest source from Github rather than the latest official package, use the –HEAD (two dashes prefix) parameter, e.g.:
brew install bfgminer --HEAD
Unlike the ASICMiner Block Erupters and Bitfury USB sticks, the HashBuster Micro requires no installed kernel extension or driver. Woo-hoo!
Once you have the proper Bitcoin mining software installed, you can use the -d? argument to list available devices with bfgminer:
[2013-12-10 10:07:35] Started bfgminer 3.8.1
[2013-12-10 10:07:38] Devices detected:
[2013-12-10 10:07:38] HashBuster.micro Project by HashBuster for Eligius.st (driver=hashbusterusb; procs=9; serial=180000005298AB36; path=usb:093:002)
1 devices listed
Once the HashBuster Micro is detected you can fire up bfminer using the -o, -u and -p arguments to start hashing away:
bfgminer -o hostname -u username -p password
