ASIC Miner Block Erupter's 101
Here is a sample picture of a USB Bitcoin ASIC Miner Block Erupter. These are commonly available in many retail outlets. These USB based devices are -simply- plugged into an USB port on your workstation. The performance on these is generally in the 336 MH/s to 2.2GH/s range depending on the type you purchase. With other words while the devices look very similar the performance may differ significantly.
If you end up purchasing more than a single USB attached ASIC miner you may need to purchase a USB hub. Here is a sample picture of a USB hub.
This is an image of a network attached Bitcoin ASIC Miner Erupter by ASICMINER. The device measuring about 6 x 6 x 6 inches is Ethernet attached to your network and needs virtually no configuration. It is rated at 30Gh/s but performs up to 38Gh/s in our experience. Setup of this device is no more than a few minutes. Since the ASIC miner only supports the "getwork" protocol you will need to set up a proxy to "translate" the traffic into the more accurate stratum format. While this sounds like a complicated process it is not. The process is not much more difficult than entering a URL/HTML address into a Web Browser.
