“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.
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.
I am selling a 6 Gh/s Bitcoin and SHA-256 altcoin mining rig. This comes with 3x Antminer U1s over clocked to 2 Gh/s, Arctic Breeze Usb Fan, 10 port powered usb hub, Raspberry Pi Preloaded with Minepeon ( More Info about that here http://minepeon.com/index.php/Main_Page ) a 8 GB SD card, and a Hard Shell case for the Raspberry Pi (Instronctions on how to set it up are in the box). It is in perfect condition and works great. If you want you can upgrade the hash rate by simply adding more miners or even faster miners. if you have anymore questions comment below!

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 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.
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.
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!
