If you just want to do it to play and make a few thousandths of a penny then go ahead, but the real money ship has sailed long ago. Sat Jan 16, am Based on a quick google, a Pi Zero would take over years to generate a block. Take what I advise as advice not the utopian holy grail, and it is gratis!! Fake doctors - are all on my foes list. The use of crystal balls and mind reading is prohibited. Sat Jan 16, pm The mining hashing is done by dedicated ASIC hard these days, because they are the only things that can do the work quick enough to be productive.
Increase in the difficulty left the high end GPU cards behind a long time ago. However, the Raspberry Pi is very commonly used in bitcoin mining as the network interface for the ASIC and to provide a website type user interface to manage the mining and your connection to whatever pool. There is a dedicated SD card image that is available for download on the web that contains the CGMiner software all preconfigured for headless use and ready to go on the Pi, all that is needed is to add the stratum for the pool, with the ASIC connected by USB.
Sun Jan 15, am There is one other option here since power consumption is a limiting factor. Solar power. A Pi 3 runs on about 10 watts. It would be fairly trivial to set up some photovoltaic panels with a large battery to keep a Pi running for however long it takes. I don't know if the mining can be stopped and restarted, or what the cost of that might be in terms of needing to catch up. If you had a battery big enough to run a week and enough panels to fully charge it in a couple hours you'd have pretty good protection against several days of gloomy weather.
Most such small PV systems are 12 volts, use redundant switching regulators to efficiently get 5 volts, feed it into the 2 or 3 pins on the GPIO connector that are 5 volts. Cut down an old hard drive cable to fit the GPIO connector, you only need a few wires. Fuse it properly. I can't do it because I don't have the bandwidth, I assume you can't mine without downloading the blockchain at least once. This strikes me as being a little like the Galamsey diggers for gold in Ghana, if you had land enough and panels and batteries enough you might almost be able to make a living at it.
No, I haven't done the math. Because the ARM chips run on low power it seems almost feasible. Running a bit OS seems like a good idea. Storing the blockchain on a shared RAID array, interfaced by netfs, so one copy could be used for all machines sounds good too. Sun Jan 15, pm Regardless of how you actually crunch the numbers, when the energy consumed becomes a factor it seems simple enough to figure out you should use free energy. There is almost such a thing. I've experimented with small wind and solar systems for about that time.
My first generation is pretty much defunct but I learned from it. Wood for solar panel racks or windmill blades has a finite life. One of the first things you learn is that the biggest cause of inefficiency is to have the capability to generate electricity and nothing to use it for. To make integration in an existing project easier, Blues Wireless provides host boards called Notecarriers.
Also, the Notecard ships preconfigured to communicate with Notehub. Notecards are assigned to a project in Notehub. Notehub can then route data from these projects to your cloud of choice e. As with any Raspberry Pi project, it's a good idea to make sure all of your installed packages are up-to-date:.
Next, we'll want to create two new System Tasks. One to shut down the RPi when the charge is too low and one to boot it up when the battery has enough charge again. Mining cryptocurrency is nothing new, so we can use one of a variety of Linux-compatible CLI crypto miners. I also decided to mine Monero , which is a cryptocurrency that is still in theory profitable to mine with a CPU only. To start, we need to install raspbian-nspawn , which requires you to be on the bit kernel of Raspbian.
Next, issue the following command to start using the bit container:. Now we need to install our miner, XMRig , from within this bit shell. Install all of the build dependencies:. Now we can create a config. Use the XMRig configuration wizard to create a starter config file for you.
Mine ended up looking like this:. In order to enable logging, add the following line to the JSON object:. Save this as config. If you'd like, you can test out your miner now with this command:. Assuming everything is working properly, you should start seeing some activity in your terminal window:. Now that we've proven our mining software functions, we'll want an easy way to monitor the production of our "mining rig". By now the log. Let's write a short Python script that will read the log on a periodic basis and pump relevant data to the cloud.
Back on the Raspberry Pi NOT in the bit container , install python-periphery for I2C , python-dateutil for working with dates , and note-python for interfacing with the Notecard :. We initialize the Notecard by specifying a productUID which is the name of a Notehub project that we'll create in a minute and setting the cellular connection mode to continuous. Normally in battery-conscious environments you would use periodic mode to reduce the frequency of cellular connections. However, in this project, the draw of our cellular modem is the least of our concerns since the mining software is going to use the vast majority of our battery.
Here is an example of a log file line that contains the 10s hash rate along with a timestamp :. Our main function will iterate through the log file to identify data that is relevant to the dashboard we are trying to create. For this project I only care about the ongoing hash rate of my miner. A discerning eye will notice that everything into and out of the Notecard is JSON-based, making it incredibly developer-friendly. For example, the generated JSON from the above note.
Save the Python script and a keys. Recall that Notehub enables synchronization of data between your device and the cloud. That's it! When the Python script runs, Notecard will associate itself with this Notehub project. Any notes events you send will show up in the Events panel when received:. Next, we want to route our data to a cloud dashboard. I've used Ubidots in the past with success, so I created a new route from Notehub to Ubidots.
You can view full instructions for creating a Notehub to Ubidots route here. Since our Raspberry Pi will be cycling between on and off states depending on the battery charge , we will want to make sure our miner and Python script also start on boot.
You can find the instructions on how to use systemd to automatically run xmrig and the Python script on the Raspberry Pi forum. For reference, here are the two service files I had to create:. And what happened when I deployed this off-grid? Well, it's another good news, bad news situation! The good news? Technically speaking, the project worked. With my data actively routing to Ubidots, I was able to create a dashboard to view my results over time:.
It was clear that I wasn't going to get too much mining done on a mAh battery.
Step 1: Updating the packages on Raspberry Pi. The first step you will need to do is to check for the updates on your Raspberry Pi terminal using the update and upgrade commands. Step 2: Create a Bitcoin Wallet. Step 3: Enter a Mining Pool.
