Bitcoin use and value is going to keep growing. It has been around long enough and has enough miners and nodes distributed around the world run by independent people that it is going to stay around for a long time. So it’s probably a worthwhile place to store some of your money. Bitcoin is also […]
Latest version of my guide to building and operating a mining rig is here, How to Build a 6 Rig GPU Miner for Zcash and Ethereum with Nvidia GTX 1070 and EthosDistro posted Oct 1, 2017 on Steemit. Bitcoin is getting all the press, and Bitcoin mining can be profitable. But the equipment is noisy, […]
Every once in a while a hashboard for an Antminer S9 will go bad. I look on the display and it has all XXXX’s on it. Before sending the board back for repair I’ll reboot it just to make sure that as soon as the machine boots up the hash board goes bad. I have […]
I just got a Bitmain Technologies Antminer R4 and APW5 power supply and I’m going to unbox and set them up. I’ve never seen one of these in operation before although I’ve operated many Antminer S7 and S9’s. R4’s sell out very quickly because they allow people to mine Bitcoin at home without deafening noise. […]
As I am running the Antminer S9’s longer, I am concerned about finding a source for repair parts. When I was cleaning one of the Antminer S7’s a fan blade snapped off, and something like that might happen with the Antminer S9’s. Already one hashing board on one of the boxes looks like it is […]
Here is a quick video showing why it’s important to clean out your Bitcoin miners, and how to get it done. It’s important to make sure there is no static electricity buildup when handling electronic components. I’m doing this on a hot and humid Georgia day. You can use cans of compressed air, but you’ll […]
One of the new Bitcoin miners I put into production last week had a problem. The fan stopped working after a little while, and it stopped hashing. The same thing happens when an Antminer overheats or has some other safety feature kick in that stops it from hashing. It’s still running, but it’s not doing […]
Operating a Bitcoin mining facility can be profitable, but you need to treat it like a business. I operate a small Bitcoin mining facility, and there is a lot more that goes into it than just plugging in the equipment and letting it run. It’s easy to set up a single Bitcoin mining device and run […]
I’ve been mining Ethereum using Ubuntu for a couple months now with Radeon graphics cards. It took a while to find a successful script. This one works for me: #!/bin/bash export GPU_FORCE_64BIT_PTR=0 export GPU_MAX_HEAP_SIZE=100 export GPU_USE_SYNC_OBJECTS=1 export GPU_MAX_ALLOC_PERCENT=100 export GPU_SINGLE_ALLOC_PERCENT=100 ethminer –cl-local-work 256 –farm-recheck 200 –cl-global-work 16384 -G -F mine.weipool.org:5555/0xac26955e90380dd1d366592ec01298a49c2a92de/115 For the complete setup, I’ve […]
Ethereum is a digital currency. It’s like Bitcoin, but different. You can buy it with dollars, and sell it for dollars. You can also earn it by having your graphics card download and solve cryptographic puzzles. It has other useful properties. Some people think it’s going to become very important. If you have a graphics […]
