I will place some links to all the parts down below so that you can get started on your project. Now, the first item that you want to pick up is called a Raspberry Pi. Now, this is basically just a credit card sized computer. Now, the nice thing about having one of these is that this is a completely separate unit from your personal computer, which means you can mine for Bitcoins 24×7 without affecting your daily computer usage. This bitcoin computer can be powered by USB cable.
The next item on the list is just a plastic case for your Raspberry Pi. Now this is an optional item but I highly recommend it because it will protect your Raspberry Pi in case anything falls on top of it.

Now this SD card basically acts as the hard drive for your Raspberry Pi. Now you want to get a 4 gigabyte minimum on this card. Now I have an 8 gigabyte just because it was on sale usb easier to find at the time. The thing that you want to focus on is getting a class 10 SD class.
So, all the parts that I just listed basically creates a separate computer. Now this computer will run the mining software. All the parts that I list next will be the actual mining bitcoin that will mine for Mining. Okay, so this is the actual hardware that mines for Bitcoins. Now this is basically just a chip that has one job and that is to mine for Bitcoins. Now this specific one mines at a rate of megahashes per second.
