Bitcoin's value is flying high currently making for lots of interest in how you earn Bitcoin. One earns any cryptocurrency by "mining", which is putting your computer's CPU power to work helping to maintain the blockchain used by the particular currency. In the Bitcoin market, the only mining equipment that is profitable are expensive ASIC-based equipment running extremely custom hardware produced for the specific task of Bitcoin mining. CPU mining, or using a regular computer, is completely untenable for mining Bitcoin, but some other cryptocurrencies are still open to CPU mining.

Because the ARM-based Linux single board computers (like the Raspberry Pi) have extremely low power consumption, they're attractive for this task. The video below goes over the steps required to set up cryptomining on Linux single-board-computers for a specific cryptocurrency.

The primary advantage is their extremely low power consumption. The main cost any cryptocurrency miner faces is the electricity required to power the machine.

Tired of paying thousands of dollars for laptops you can't customize? We used to be able to take apart laptops, fix anything, upgrade them any way we want. Increasingly we're facing laptop choices where the need-for-thin and lightweighting means laptops are glued together, with components soldered to logic boards, and the whole thing is unfixable and unupgradeable. One response is what I've done - this is being typed on a 2012 MacBook Pro that's upgraded to the max in the hope it'll remain viable until sometime in the future when Apple wakes up to what we want. The mindset currently running Apple is missing something big.

Another choice is what's shown in this video -- find out a way to make your own laptop using cheap DIY methods. DIY computer hardware is growing more powerful every year. The exact build shown here is pretty ridiculous, so we should treat this as demonstration of a minimum-viable-product rather than a completed anything. Namely, the build shown here is a Raspberry Pi in a rough cardboard case, a pair of 18650 battery cells with a voltage regulator for power, various hacked up cables, a simple HDMI for display, and everything hot-glued together.

There are several ways to improve on this -- for example the Orange Pi and Banana Pi lines both include boards with 2GB of memory and support SATA drives -- hello large SSD for fast mass storage. And it should be possible to rig up a proper rigid case and a better keyboard/mouse. For a display it's possible to get a laptop display, remove the LCD portion, find an HDMI driver board, and rig it up in a bezel.

The UDOO Advanced Plus is so much higher priced than most single-board-computers that it doesn't fit the Maker Project idea. At $160 or so per board it's not like taking a $35 Raspberry Pi to toss into a project. Where the UDOO shines, though, is as a desktop computer. Because it has an x86 CPU, it runs regular operating systems, and the board includes normal ports for connecting to SSD's and hard disks and whatnot. The peripherals include a pair of M.2 ports for WiFi and SSD support, a SATA to connect up a regular disk, 3x USB3 for high speed peripherals, an HDMI and 2x Mini Display-Port connectors allowing you to connect three large screen monitors, etc. In other words, while the UDOO is a smallish computer, it's got a lot of powerful capabilities.

For more information on the UDOO Advanced Plus. Both the UDOO and LattePanda are inexpensive single-board-computers that are useful for building custom computers. This video compares the two, and finds the UDOO is more powerful and more flexible. Both run Windows very well as long as your needs are somewhat modest. Both are more powerful and flexible than the Raspberry Pi, another favorite of building custom computers.

What are the best linux-single-board-computer's? There are many of these things, and running linux on a tiny computer is awesome, but the wide variety makes it difficult to choose. Do you go with the Raspberry Pi just because it's the most popular? Or because your buddy down the street got one? Some of these computers have significantly important features giving a clear advantage for certain purposes.
