It must be noted the 560 MHz figure comes from replacing the 12 MHz crystal with a 20 MHz one, and this mod only lasted about 20 minutes on ’s bench until the magic blue smoke was released. Effectively, he’s running two Block Eruptors for the price of one with the potential to actually make back the purchase price of his hardware. By changing out the 12 MHz crystal connected to the ASIC and fiddling with the voltage with a trim pot, was able to overclock the ASIC core from 336 MHz to 560 MHz. Inside, he found a custom ASIC chip, an ATTIny2313, a USB UART converter, and a voltage regulator for the ASIC. begins his tutorial with a teardown of the Block Erupter hardware. This speed isn’t enough for some people, like who overclocked his Block Erupter to nearly twice the speed. Now, hardcore miners are moving on to custom ASIC chips like the Block Erupter, For around $100 USD, you too can mine Bitcoins at 300 MH/s with 2.5 Watts of power and a single USB port. If you just want bitcoins then invest in serious mining hardware or just buy bitcoins.The name of the game in mining Bitcoins isn’t CPUs, GPUs, or even FPGAs. We don’t blame you, if you’re not impressed though! USB Bitcoin mining was only profitable when Bitcoin was in its early years. We just included it in this list since it's still technically a USB miner. It’s not a very good choice though in terms of $ / hash rate. However, via USB you can plugin it to your computer. The 21 Bitcoin Computer isn't the typical USB Bitcoin miner. What’s great in this is you can do some mining while providing internet for all your devices because it works as a wireless router. It's cheaper, but with that you just get a 5.5 GH/s, a low one which is a little over $1 per year. Bitmain Antrouter R1 Wifi Solo Bitcoin MinerĪlthough not exactly a USB miner, the Bitmain AntRouter is just similar. You just need to plug it into your USB port on any computer and also no fan is required. The Avalon Nano 3 is a 3.6 GH/s miner, which will earn you almost a dollar per year. It will yield you about $0.15 per month, which will give you more than a dollar in 12 months! The device runs completely silent, as the company claims. Just slightly better than the original block erupters is the GekkoScience miners. GekkoScience Compac USB Stick Bitcoin Miner This is the best choice if you want to see how mining works, but just the like with most USB miners, a profit should be least expected. They have 330 MH/s of hash power which will give you less than $0.01 per month. The first Bitcoin USB miners were the Sapphire Block Erupters. ASICMiner Block Erupter USB 330MH/s Sapphire Miner
