Dec 27, · Used Bitcoin Mining Hardware for Sale The growth of the rate, interest in mining returns, and the unsuccessful period in the market left many used devices in the secondary market. In China, electricity cost did not cover the minimum profitability, so thousands of inexpensive devices appeared on the secondary market. 7 Best Bitcoin Mining Hardware in (July ). Dec 22, · Mining with the Raspberry Pi The Raspberry Pi is a credit card sized computer that is a completely separate unit from your own personal computer. The great thing about mining with a Raspberry Pi is that you can mine for Bitcoins 24/7 without .
Best bitcoin mining hardware diy7 Best Bitcoin Mining Hardware in (Jan. )
This will reduce any chances of bottlenecks that will prevent the Raspberry Pi from reading the software data on your card. There are many mining software to choose from but I am currently using the MinePeon Linux operating system which is preloaded with BFGminer mining software.
MinePeon cannot be easier to use! All you need to do is download the MinePeon disk image and burn it to your SD card using any image writer. I did this on Windows operating system using Win32DiskImager. You can also use the built in software of OSX if that is what you are running.
Once you have your mining software imaged burned to your SD card, insert that card into the SD slot of your Raspberry Pi. Performing the steps above will basically just create a stand-alone computer to run your mining software.
Next we will dive into setting up the actual Bitcoin mining hardware that does the job of mining Bitcoins. Speaking of USB hubs…. The USB hub is a part where you do not want to cheap out on. The reason you need a quality hub is because you need to ensure that each individual USB port on the hub is providing consistent and constant power to the Block Erupters. Cheap USB hubs are known to fluctuate their amperage depending on how much load is on each port.
This will hinder the performance of your mining hardware thus costing you the amount of Bitcoins you could have mined. Hooking up all the parts is pretty self-explanatory. If you need a visual guide, the video above will go over every step of installing your Bitcoin mining hardware.
Once everything thing is plugged in, you are ready to run your mining software and set up your mining pools. I will create another video and article detailing step by step instructions on how to set up your mining software if you need additional assistance.
Tags asic miner bitcoin bitcoin miner bitcoin mining bitcoin mining hardware bitcoin mining software block erupters headline minepeon mining rig raspberry pi raspberry pi miner. Not a bad set up I run the anker hubs and the bfg miner straight through the computer, along with some bf jalapenos.
Yah the raspberry pi is working out nicely. Im thinking about picking up some jalapenos at some point. Hi Ray, I have the second part uploaded now. This should give you a good idea how to setup your miner.
Hi Fred I was looking for some stats on how much electricity this thing consumes and a rough estimation of how many bit coins it can produce? Could you please maybe make a video or make a post? Great video, I am currently using 2 antminer u1 on my pc.
I want my pc back for other uses. Will the Rasberry pi set up work with the antminer. I had to use specific software to get the antminer to run. Would I copy that software to the sd card? Thanks for any help, I really want to try the Rasberry set up. However, keep in mind that the Raspberry Pi is just another computer. You can not simply copy the mining software to the SD card. You have to first load the SD card with Linux, then install the mining software into the Linux operating system.
The raspberry pi has 2 usb ports. You can plug in usb hubs to each port and even plug in additional usb hubs to other usb hubs. So it is almost unlimited to the amount of usb ports on your hubs. Thank you very much for your tutorial. I think I can do it, the mining hardware seems clear and simple with your video. Yes it is the power supply for the raspberry pi. You can either buy a charger, or use a usb cable and connect it to the usb hub.
Hi fred. What do i have to do? Install linux on sd card and then what software? Linux fits in a 8gb sd card? Ok thanks. Shouldt you connect raspberry pi to one of the usb ports, and then the usb hub connect it using an adapter? I am new to this and i am making my research about this thing work. Now i am in my building phase.. I just want to ask how much is a 1 block eruptor and where can I buy? Went back to 6 and life is good. Thanks again.
Hi Fred- Nice and easy to understand videos, thanks I checked out on the Raspberry pie, it says it should be ran on a Linux-kernel based operationg system what is it? My PC run windows… thanks, S.
Its hardware is not available for purchase. Power Supply — Bitcoin rigs need special power supplies to funnel and use electricity efficiently. Cooling Fans — Bitcoin hardware can easily overheat and stop working.
Buy a sufficient amount of cooling fans to keep your hardware working. Backup generators — You may want generators as a backup in case your main source of electricity goes down. You can find Bitcoin mining equipment for sale on eBay. Bitcoin is based on blockchain technology, a decentralized platform which takes power away from a central authority and gives it to the average person.
Sensitive information is stored on the blockchain rather than large data centers, and is cryptographically secured. A vast amount of people, known as miners, all work together to validate the network, instead of just one person or government. In the beginning, CPU s were used to solve cryptographic hash functions , until miners discovered that GPU s were far better equipped for mining. As block difficulty increased, miners turned primarily to GPUs. Their hashrates are significantly higher than anything GPUs are capable of.
With stellar performance comes a high price tag — the best ASIC chips will run you a few thousand dollars each. Upon creation, Bitcoin blocks were confirmed by the average person using their desktop — once ASICs hit the market, things changed. ASIC developers, including Bitmain, granted early access to large mining cartels rather than the average person. Nowadays, a large majority of Bitcoin mining takes place in China where electricity is cheap.
Thousands of ASICs all mine simultaneously in a mining farm large warehouse. Unfortunately, Bitcoin is no longer as decentralized as it was once intended to be. Buy Antminer S7 on eBay. The S7 is also a popular choice among hobbyist miners for its reasonable price and strong performance.
The strong metal casing features a tongue and groove system which allows for the neat arrangement of multiple miners. The APW3 requires a minimum Volts to function and does not ship with the necessary 16A power cord. While an integral PSU makes for a compact and convenient miner, there are few other reasons to recommend such a setup. The S7-LN also excludes a cord. Note: Before you buy an Antminer S7 make sure you already have Bitcoin mining software and a Bitcoin mining pool.
These prices can be expected to fall further as the S9 and other superior mining hardware becomes the new standard. With careful tweaking, it may be possible to profit from an S7 even at 15c power. The same calculations adjusted for the Hash Rate and Power consumption of the S7-LN produces slightly more encouraging results:. Naturally, the hotter the environment, the more energy the fan s will consume to cool the unit.
The S7 is twice as efficient as the S5 at converting all this energy into bitcoins; it requires a modest 0. Setting them up via the MinerLink GUI is a simple process, requiring only your mining pool credentials to begin mining. The units will automatically begin hashing upon powering up, which can be helpful in the event of power failure. S7 connectivity is via Ethernet only.
They are both cooled by dual fans. A dry basement is an ideal location. This peak was reached on May 24 th Such tremendous growth has been spurred by major investment into Bitcoin mining technology and operations.
Profits have accumulated where mining is most profitable China , with the result that several competing operations eg. KNC have been forced out of the industry. We have tried to calculate the amount of money that the Chinese have invested in mining, we estimate it to be in the hundreds of millions of dollars.
Even with free electricity we cannot see how they will ever get this money back. The same Chinese competitive advantage has been doubly effective at squeezing the profit-dependent hobbyist miner from the market. With the block reward halving looming, the profitability of all but the most efficient operations will likely be challenged. Given that profits derived from the current generation of mining hardware are dwindling and will likely reach negative returns post-halving:.
Can the new S9 change the game for smaller and hobby miners and restore their lost profitability? Note: Before you buy an Antminer S9 make sure you already have Bitcoin mining software and a Bitcoin mining pool. The first batch of S9s will be available for order directly from Bitmain from the 12 th of June. However, the lower your electricity costs, the better your odds of the miner paying for itself within a reasonable timeframe.
Judging value in this space is a complicated exercise, although it would appear that nothing vastly technologically-superior to the S9 is likely to be released in the near future. The release cycle of a new generation of mining hardware every few months is likely to decelerate from this point on, as manufacturers have transitioned to cutting-edge 16 and 14nm designs.
The on-going miniaturisation of semiconductors allows ever greater computing power and electrical efficiency, but the process cannot continue forever with the current technology.
The 16 nm fabrication process used in the manufacture of the S9 is a major improvement upon the 28 nm design common to other modern mining devices. Although a 10nm process is on the horizon for , further increases beyond that remain theoretical. Further, the design and manufacture of any 10nm Bitcoin mining hardware is likely to take at least a year.
Our guide on the best bitcoin wallets will help you get one fast and for free. Read it here! The good news is that existing power supplies, at least those of sufficient wattage, are fully compatible with the S9. A total of chips, spread over 3 circuit boards, are combined to achieve this phenomenal hashrate. Note that Power Cost will be specific to your location and that Difficulty changes every 2 weeks, usually to the upside…. Your Pool Fees will be determined by your mining pool; although the S9 is plenty powerful, a single unit is highly unlikely to find any blocks when solo-mining.
Of course, such impressive results assume all factors stay constant which is hugely improbable in the ever-changing world of Bitcoin! The cutting-edge manufacturing process is what makes the S9 the most electrically-efficient mining device to date.
It uses a mere 0. The S9 consumes about W more than the S7. Apart from the power supply, the S9 is a self-contained unit. It requires no connection to another computer to interface with other Bitcoin nodes. The S9 performs reliably in any well-ventilated space, whether a single or several unit s kept in a spare room or hundreds to thousands of units in a large mining center. On the other hand, the halving could bring about a higher Bitcoin price and reduced competition, increasing profitability.
It is likely to remain profitable for far longer than previous generations of ASIC miner, although ROI cannot be guaranteed given the inherent unpredictability of Bitcoin mining. Bitmain is regarded as one of the most influential companies in the ASIC mining industry. Halong Mining is no longer around. It seems they could not compete with the already established ASIC manufacturers, most likely because they could never fill their orders and get the partsd they needed to produce enough miners to make money.
The DragonMint W power supply is strongly recommended, though not mandatory. Each miner requires its own individual power supply. Professional mining hardware runs optimally at V, hence why mining farms step down their own electricity supply to V. In any case, it would be a good idea to buy the DragonMint power supply. These PSUs will get the job done, but they are not ideal for optimum mining performance. Consuming merely 0. Keep in mind that exact power consumptions vary, especially depending on which power supply you are using.
Take a look at the projected mining profitability of a single miner :. The Antminer R4 hashes at up to 8. BitFury was the first company to release 16nm chips. As the saying goes nothing good comes cheap.
