Mining machine connected to computer
At present, the mining machines in the market are mainly divided into two categories, one is PC based mining machine, the other is professional mining machine based on ASIC chip
the general PC mining machine can be used as a home computer, but the CPU performance is weak and the power consumption is high. Professional mining machine based on ASIC chip can not be used as ordinary computer because it has no graphics card and does not support mainstream desktop operating system
extended data:
mining machine is one of the ways to obtain bitcoin is a kind of network virtual currency proced by open source P2P software. It doesn't rely on a specific currency institution to issue, but is generated by a large number of calculations of a specific algorithm. It uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions economically. The decentralized nature of P2P and the algorithm itself can ensure that the currency value cannot be manipulated by mass proction
any computer can become a mining machine, but the profit will be relatively low, and there may not be one in ten years. Many companies have developed professional mining machines, which are equipped with special mining crystal. They are tens or hundreds of times higher than ordinary computers
mining is actually a competition of performance and equipment. The mining machine composed of many graphics cards, even if it is just a garbage card like hd6770, can surpass the single graphics card of most users in terms of computing power
and this is not the most terrible. Some mining machines are made up of more such graphics card arrays. When dozens or even hundreds of graphics cards come together, the graphics card itself costs money. Considering the hardware price and other costs, there are considerable expenses in mining
in addition to the display card burning machine, some ASIC (application specific integrated circuit) professional mining machines are also put into the battlefield. ASIC is specially designed for hash operation. Although the performance may not be able to kill the display card in seconds, it is already quite strong. Moreover, because their power consumption is far lower than that of the display card, it is easier to form scale and the electricity cost is also lower, It is difficult to compete with these excavators. And this kind of machine will be more expensive
Bitcoin miner is the equipment for bitcoin mining. The miner can be used as an ordinary computer
bitcoin miner can be USB miner or professional ASIC miner. It's true that bitcoin can be mined with ordinary computer CPU, but it's difficult for indivials to find bitcoin with ordinary computer
Mining needs high-end graphics card, just to solve the problem of high-end graphics card is not easy to sell
the money g can't fill the electricity bill hole
the configuration of home computers is low, and the computing power of graphics card can't keep up,
mining machines are generally equipped with server power supply<
now mining mainly relies on graphics card (GPU), ordinary home computers, which may be able to dig a coin for hundreds of years
now mining has entered the era of specialization and clustering. Without professional mining machines, there is no profit (because you have the cost of electricity). How can you compete with tens of thousands of other machines. If you really want to do mining, Jianye will buy a special miner to join in the large-scale mining pool.
unknowingly, it came to 2014, with several Avalon generation USB mining machines in hand. You're right. It's not a roasted cat USB miner or any other chip. It's a USB miner of Avalon generation, with a single computing power of about 300m. Of course, the USB mining machine with more than 300 m computing power is of little practical value. It's just a souvenir for everyone<
first, the appearance
first, let's look at the appearance. The workmanship is regular, not exquisite, but slightly rough:
Second, the required software
let's start running cgminer to see how to use it in practice. Before starting work, you need to download three softwares:
1. Cgminer. Anyway, the latest version of 3.9.0 is also available for testing, http://ck.kolivas.org/apps/cgminer/
2. Zadig. This software is needed to replace the driver later. Download it from the same directory as cgminer
3. USB driver of mining machine, http://www.silabs.com/procts/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx
3. Install and run
after downloading the above software, start to install and run
1. Insert the USB miner first, and you will be prompted to find the new hardware, and then complete the driver installation according to the prompts
2. After the driver is installed, you can see the new things in the device manager
3. Run Zadig, first click options -- list all devices, then drop down to select port, and replace the driver silabser (v6.6.1.0) with the driver WinUsb (v6.1.7600.16385) recognized by cgminer. After this step is completed, it is recommended to restart the computer
4. Create a new batch file in the cgminer directory, The following command: cgminer - O pool address - U miner name - P 123456 -- Icarus options 115200:1:1 -- Icarus timing 3.0 = 100 -- USB: number of mining machines
there are six USB mining machine fish pools, for example: cgminer - O stratum+ tcp://stratum.f2pool.com : 3333 - U AAAA. 2 - P 123456 -- Icarus options 115200:1:1 -- Icarus timing 3.0 = 100 -- USB: 6
since cgminer3.2.0, The method of supporting USB mining machine is modified, which does not need to add the - S - com parameter
5, run batch processing, and start to display mining data, about 300m, which is basically normal.
all oil holes on the machine and all rotating parts should be refueled with clean sewing machine oil every 4 hours. Other oils and unclean sewing machine oil should not be used, so as not to affect the service life of the machine
(2) regular maintenance and inspection
it is necessary to keep the parts clean, regularly check whether the temperature and sound of the rotating parts are normal, and repair them immediately if any problems are found, so as to avoid damaging the machine
generally, minor overhaul is concted once a month, and cleaning and major overhaul are concted once a half year. After being put into use for a long time, it should be cleaned and overhauled first
the thickness and use speed of the sewing material should be selected within the specified range, and it should not be overloaded or over speed.
radiate WiFi with a computer. Then the miner is connected
