“Bitcoin” mining on Raspberry Pi 3 with multiple USB miners
I’m just trying out “Bitcoin” mining to familiarize myself with the world of mining before investing in more powerful Th/s miners. I plan to use one of my Raspberry Pi’s with a powered USB hub connected with possibly 2-4 USB miners running with a USB fan as these things get pretty hot. Possible miners would be multiples of the Antminer U1, Antminer U2, or the GekkoScience device. My questions are: 1-Will a Raspberry Pi 3 work with a USB hub? 2-Can CGminer run properly with multiple devices and be able to consolidate the processing power of each miner? Thanks in advance.
Hi! I am looking for old used ASICs - AntMiners (S1/U1/U2), Gridseed (5-Chip/Blade), and ASICMiner (333mhz, ect) and so on. Have BTC in hand, positive feedback/rep on BitcoinTalk. Let me know what you have. Thanks!
Unsure if scam or mixup. Need other input on BitcoinWare.net from experienced buyers.
My boyfriend and I recently got into mining and planned to start small and get bigger. We saw that BitcoinWare.net had a Canada Day sale with free shipping and a sale on Antminer U2 units, so thought that it would be a good place to start with minimal investment. So we dropped $60 on 3 units, received a confirmation email and could check the status on the website. A few days after that though, I received an email from them saying that they had over sold the U2 units and asked if I would rather the option of: a) a full refund. b)wait 1-2 weeks for the units to restock for shipping. or c) to change my order to another item on their site using the already paid money as a credit towards the purchase. We opted to wait for the U2 units (as they were $20 a piece), and sent them an email immediately. almost 2 weeks went by without word back from them before my boyfriend noticed that the U2 units on their site were in-stock. So we sent them another email inquiring on the status of our shipment and within 2 hours we received 2 emails. an email confirmation of shipping and one stating that they apologize for the delay and asking if we received confirmation that the shipment was sent. We responded that we received confirmation and that we were happy with the timeliness. That was the last time we had heard from them. Within a week we received the package, but upon opening the package, there were 3 units, but all of them were U1 units, Not U2. We immediately emailed them inquiring as to what could have happened and if there was any way to remedy the situation. However, that was over a day ago and we have not received word from them in any way. Their website is only 4 months old, about as old as their Reddit User account u/bitcoinware . TL;DR Paid for 3 U2 Antminers from BitcoinWare, received 3 U1 units after asking what happened to our order. Has anyone else had similar experiences with this seller or any sellers like this? If so, what happened? and what do? Edit: Finally heard back from BitcoinWare.
Hello, We received your emails and contact form submission, sorry for the delay in responding. The U1/U2 are the same thing. They both use the same chips and can achieve the same hash-rate in our testing with the same settings. The only difference is the shape of the heatsink. Since the factory does not make this product any longer, they were shipping both types in the same batch just with different heatsinks for the last shipment. Please note it states on the product page: "The color and the shape of the heat-sink and product appearance may vary slightly from the pictures." If you are not satisfied, you can return the products for a refund. Alternatively we can provide you a discount for future orders if there is a problem with the products you received. Please let us know how you would like to proceed. Best regards, BitcoinWare
...Pretty sure this is a scam now... What I got. What they are advertising. Receipt that came in the envelope with miners Edit2: So BitcoinWare has sent me an email saying that they would be willing to offer a full refund with the option of keeping the units because I was unsatisfied with what I had received. The reason is due to the information they were provided by their supplier, so they did not intentionally misrepresent their product as U2s. Previous clients apparently where fine with what they received so it had never been an issue for them before. I've replied asking to settle instead on $6 off the total order ($2 a unit) for the cost of purchasing proper heatsinks for the units and materials to attach them so that I'll be able to get the 2GH/s promised on their site. I have yet to hear back. I think in the long run I don't believe that these people are a scam, but it's probably best to get confirmation of product prior to shipping in the future. Final edit: They sent me a $10 refund so I can buy heatsinks so that's all settled with. TL;DR: Though their supplier sounds sketchy, BitcoinWare is not a scam and are just really slow at getting back to you. Confirm before ordering, but you will get products.
help in choosing mining hardware for profitability?
I just bought an antminer u1 which hashes oc'd at a stable 2.4GH/s for $30 shipped on ebay. I'm currently using it to mine bitcoin on bitminter. is there a more profitable sha256 altcoin? is there a more profitable pool that i should be looking at? from what I see of my current calculations, antminer u1 is unprofitable per http://www.bitcoinx.com/profit/ as it will take 3 years to make back the $30. I'm currently running all kinds of calculations on the profitability of an additional hardware investment. the antminer s1 seems to be a (fairly) reasonably priced miner (~$300) (though i'm very annoyed they don't include a power supply grr which would be another $150 or so making the hardware investment $450) that can do an advertised 180GH/s with promises of 200GH/s overclocks if i void the warranty at ~400 watts (which im sure is really closer to 500w). My current power rate in my area (i just looked at my bill and added up all the extras and such) is .36/KWh. what do you guys think of general hardware bitcoin mining profitability? are there other asic miners that i should be looking at? EDIT: my apologies, I reworked all the numbers again and it looks like i'm only paying .162/kwh sorry about that... i was busy at work when i went through it the first time.
Help setting up bfgminer, unexpected extra commandline arguments
So I've now got 5 u1's and a sapphire usb miner that im trying to get working under bfgminer. I followed the guide on bitcoin talk and use this batchfile. bfgminer.exe –set-device antminer:clock=x0781 -o stratum+tcp://us-west.multipool.us:8888 -u Smend.2 -p x -S antminer:all pause But I'm getting the unexpected commandline arguments in the console window. I dont want to use cgminer because the added driver that needs to be installed disables the sapphire miner. Thanks for any help.
Holy WOW! This is such cool. I'm hooked! What do I do now? Where to start? OMG to the moon. Yippie Yippie
Hi Shibes.... I just found out about doge coin and I'm so pumped....WOW....SUCH....THIS IS AWESOME. I had no idea you could mine coins on a PC. LOL.....to the moon. Awesome! Guys....I can't even think straight because I feel like I've been reborn. I have a new life with doge coin! God dang it....this is such cool. Where do I start? At the moon? (lol joke) No serious though....I'm pumped up and wanna started mining. How do I do it? I'm using a 2010 Mac Pro desktop. How do I get this thing mining? God dammit...I can't think straight because I'm so excited. This is my new hobby you guys. I'm so happy to be apart of this community. Whats the best way to contribute here? Shibes? I was looking on ebay for a "acis miner" and I found this. It's a miner in my price range. Should I buy it shiberinos? Thanks for all the help. I finally feel like my life has meaning. This is so dang awesome. Yeeeahhh baby.....I'm back in the saddle.

Link to Part 1 Continuing in my attempt to overclock an Antminer U1 to 2.8Gh/s I acquired the replacement resistors, new heatsink, thermal compound, and some Chip Quik to make removing the old SMD resistors a simple task. Heatsink: Enzotech CNB-S1 Thermal Compound: Tuniq TX2 3.74Kohm Resistor: Panasonic SMD 0603 resistor 10Kohm Resistor: Panasonic SMD 0603 resistor The first step was to remove the 1Kohm resistor in the R1 location. After wiping the board down with an alcohol pad, adding flux, and a little dab of Chip Quik on one side of the resistor kept the solder molten long enough to heat up the other side and slide it off the board. Antminer U1 with R1 removed Next step was to clean off the old flux with another alcohol wipe, inspect the board to make sure I hadn't lifted the solder pad, apply more flux and solder in the 10Kohm resistor, followed by the 3.74Kohm resistor. I ordered a bunch of the 10Kohm resistor as they were really cheap, but the tolerance is 1%, so I went through a few resistors on the multimeter before finding a 10.01Kohm resistor. As there was already solder on the pads for R2 it was just a matter of using tweezers to hold the resistor in place while applying heat to one pad. After that it was trivial to just apply heat to the other end and get a good connection. The 3.74Kohm resistor is 0.1%, so I ended up settling on a 3.72Kohm out of the few I ordered. Adding the R1 resistor was as simple as the R2, though I had to add a bit more solder on the side that had been Chip Quik'd. Another clean and inspection resulted in the following. Antminer U1 with replaced R1 and R2 The final step was to chop off the side mounts on the heatsink and drill two holes to mount the Antminer to it. A quick bit of metal cutting with a Dremel got rid of those, and also smoothed off the rough edges. I ended up having to position the Antminer at an angle on the heatsink to get it to fit nicely. A 2mm bit drilled the correct size holes to accommodate the two screws that held the old Antminer heatsink in place. I didn't have to tap threads into the drilled holes as the screws were strong enough to cut into the copper on their own. A small application of the thermal compound to the gold plated area on the back of the Antminer (refer to Part 1 images) and I attached the Antminer securely to the heatsink. Top view of Antminer U1 attached to heatsink Bottom view of Antminer U1 attached to heatsink Bottom view of other side I apologize for the awful camera potato pictures, I'll attempt to get a proper camera and take nicer ones at some point in the near future. Now for the moment of truth, after unplugging all the other USB miners I slotted the modified Antminer and started up bfgminer running the ASIC at stock frequency. After letting it run for about an hour without anything catching on fire or exploding it was time to up the frequency. I slowly upped the frequency to 350MHz to try reach 2.8Gh/s, though at 350MHz I ran into what I'm assuming are power supply issues and the hash rate dropped to 0.8Gh/s, but didn't throw any HW errors. At 300MHz it hashes away happily at 2.58Gh/s with no HW errors, so I'll leave it at that speed for 24 hours and see what happens. Thanks for reading, hope this helps other people overclock their Antminers.
I just did a 12 year stint in federal prison for sexual assault on a minor. I've been rehabilitated and I'm looking for a nice clean hobby. This mining thing looks cool?
Where do I start? Whats a good miner to get? I'm using a 2005 e-machine that my brother gave me. Can this computer work for mining? Also...I was looking at buying a asic miner. Is this a good one to buy. Thanks so much.
I know it's not a big deal for many of you here, but in less than a week I will have my first full bitcoin. It's been a fun 6 months getting to this point, and I am looking forward to going to the moon! Here's how I got to where I am now. Back towards the last half of December, 2013 I started purchasing a little bit of bitcoin. .03 one day, .05 the next, etc. It was just a couple of hundred bucks total, but at the time it was all I could afford to lose. Then around the beginning of January the value of bitcoin rose to where I had doubled my initial investment, and I cashed out at about $400. I was hooked however, and I used that money to purchase a couple Antminer U1 USB miners. I also started a little cryptocoin blog. From there I used the BTC I mined, more cash, and some very beneficial trades with a local buddy to increase my mining capabilities. I had a couple Block Erupter Cubes at one point, then later sold them on eBay, and bought an Antminer S1. But my addiction didn't end there. I continued to reinvest the BTC I was mining, and some cash to purchase a couple more Antminer S1's as well as cables, power supplies, etc. Whenever possible I purchased what I needed from Overstock.com and other places using bitcoin rather than cash. So, now I have 3 Antminer S1 units, and a few miscellaneous USB miners digging away at about 606 Mh/s. When I got my 3rd Antminer S1 I decided that was enough mining equipment (....for now LOL), and I started letting the BTC accumulate rather than spending it. I have actually mined almost 2 BTC at this point, but there has never been a point where I had a total of 1 whole BTC at any one time. I kept spending it on mining, as well as a few other items I wanted. Things like bitcoin stickers for my car. In less than a week that is about to end, and I will be joining those lucky few who actually have at least 1 BTC. Now that I know the time it's going to take me to get to 1 BTC will not be affected by another difficulty increase I am able to predict the approximate date and time that I will reach a total of 1 BTC. People outside the bitcoin world just wouldn't understand my excitement at almost reaching a total of 1 BTC. They would think I was nuts (and maybe I am a little bit). But I know that many of you here can appreciate how I am feeling. Thanks to everyone here for all that you do in support of the bitcoin community! I couldn't have gotten here without you all.
Bitmain AntMiner U1 1.6GH/S USB Miner: Worth getting?
Hi all! I'm relatively new to mining and wanted to ask if the Bitmain AntMiner U1 1.6GH/S USB Miner was worth getting to mine some btc, given the difficulty right now, do you guys this 1.6Gh/S is enough to consider getting one? I've heard you generally need more than one to mine anything significant, I'd really appreciate some advice before I get one. Also I can try to mine something else and convert it to bitcoins if that works but the asic miners can only mine SHA-256 I think. Thank you!
How do you get started with USB ASIC miners? Is it worth it?
I see the AntMiner U1's and the Butterfly Labs 5GH/s rig and I wonder if these are good investments or not. What is the best USB stick for bitcoin mining right now? How long will ASIC miners be useful?
I’ve seen plenty of pages on the forums, reddit and personal websites troubleshooting and giving instructions on how to mine bitcoins with the AntMiner u1 using CGMiner and BFGminer, but had little success getting it to work until after plenty of hours of troubleshooting, searching, and head-scratching. Here is a step-by-step of information on getting your AntMiner to work with BFGminer. I’m not a coder or anything like that so I left this simple so it’s accessible to those who also aren’t familiar (also since I couldn’t have made it more complicated even if I would have wanted to!). Here it is: http://principledliberty.wordpress.com/2014/01/28/setting-up-antminer-u1-to-mine-bitcoin-with-bfgmine Hope this helps those who have had problems, any suggestions for edits/additions to the post are greatly appreciated, as I am not a techie and could benefit from suggestions.
