NEW! Yellowjacket 2.2gh/s - 3.0gh/s USB Asic Miner (Bitfury) BTC , Not Antminer

Great product and a really great vendor with prompt attention to details and a really great opportunity to provide useful production.

Works good when over clocked

Real world hash rate w/o overclocking is 1.95-2.15 Gh/s. It's always exaggerated. I run these with bfgminer and they're fine. Stale/rejected/hwf rates are higher than antminer and block erupter, but it's still less than 1%. Overall it's a good value around $20 relative to other usb miners.

The major costs of bitcoin mining are the initial cost of the hardware and the ongoing cost of the electricity. If you run this miner on a desktop computer, you are burning 100s of watts keeping your computer running, and you will not recover your electricity costs from the bitcoins that you can mine with this miner. However, this miner will run from a USB port on a desktop computer using the latest version of cgminer (probably bfgminer too -- I haven't tried it) and with the appropriate USB drivers for your operating system (I use Linux on my desk top, so no extra drivers are needed.) Bitminter will not run the Yellowjacket (as of 18Feb14) and probably never will.A more sensible way to use USB ASIC miners is to run them from a Raspberry Pi which only uses a few watts, not 100s of watts like a desktop computer. You must use a powered USB hub in order to run them from a Raspberry Pi, because the Pi will not supply the power needed by the miner. Note that the power supply sold with a powered hub will not be enough to power a miner in each port of the hub. Inadequate power is the most common source of miner instability (I am using an old computer power supply to power my hubs.) For example, I have two 10 port hubs with 20 Block Erupters running on a single Raspberry Pi producing 6.6Gh/s which uses less electricity than the Yellowjacket on a desktop computer, and produces twice the Gh/s.The latest cgminer software will run a Yellowjacket miner from a powered hub on a Raspberry Pi, but you have to slow down the USB ports on the Pi in order for the Yellowjacket miner to be stable. This means that the Raspberry Pi can not run both a Yellowjacket miner and a Block Erupter miner at the same time because they require different USB port configurations on the Pi.I have not tested an Antminer, but I think that an Antminer and a Block Erupter have compatible USB port requirements, in which case an Antminer will not run on the same Pi as a Yellowjacket miner either.I have a single Yellowjacket miner, so I don't know whether or not a Raspberry Pi can run more than one Yellowjacket miner. I have to overclock (52) my Yellowjacket miner in order to get 2.0 Gh/s. It produces 1.7Gh/s with the default clock setting (50). I will not get another Yellowjacket miner.
