The public has latched onto the recent market events with an intense curiosity brought about by a greed for instant riches. An unfortunate side effect of mass interest in a subject is the wildfire-like spread of misinformation.
So, what exactly is a blockchain, and what can you still do now that everyone has finally jumped on the cryptocurrency bandwagon? With all the hype surrounding cryptocurrencies and the current high not quite so high but still pretty eye-watering price of Bitcoin, there are some things which might once have been pure folly that could now be deemed worthy of pursuit. There is an excavation mission being considered to unearth a hard drive containing an early Bitcoin wallet in a Welsh landfill, for instance.
But a more approachable task for you may be the possibility of mining using minimal hardware. Part of this is the timeless pursuit of answering the joke question: Is it a worthwhile punt at a prize for a minimal investment? He gives us a rundown of some of the statistics involved, and comes away with the conclusion that it is something like a not-very-good lottery ticket.
The ESP performs hashes per second while the entire Bitcoin community manages about 1. This he calculates gives him a 1 in 10 16 chance of mining a block every ten minutes, which for the tiny cost of an ESP and its relatively frugal power budget is a chance he sees as worth taking. So far he has implemented the hashing algorithm and verified it against a known hash on an already-mined block.
The ever-prolific [Ken Shirriff] has tried it on an IBM mainframe and a Xerox Altoand you can of course do it the old-fashioned way. In days of yore, one could mine Bitcoin without much more than an AMD graphics card. This latest project, however, goes completely in the other direction: Note that this is technically the most powerful rig ever made… if you consider the power usage per hash.
Engineering wordplay aside, the project is really quite fascinating. Bonus points if he can get retro. The IBM boasts some impressive stats for the era as well: It can store up to 16, characters in memory and uses binary-coded decimal. At 80 seconds per hash, it would take longer than the lifetime of the universe to do, but it is quite a feat of computer science to demonstrate that it is technically possible.
He turned to RetroMinerthe Bitcoin miner made for an original Nintendo. Like the NES miner, [mike] is offloading the communication with the Bitcoin network to a host computer, but all of the actual math is handled by a single core on the Propeller.
After hearing about cryptocurrencies like Bitcoin, Litecoin, and Dogecoin, [Eric] decided he would have a go at designing his own mining rig. The goals of the project were to have a self-contained and stackable mining rig that had all the parts easily accessible. The result is this awesome computer enclosurewhere GPU mining and traditional woodworking collide. Biking with headphones is dangerous.
While dumpster diving [Mike] found a Macbook pro. It was missing a few things, like a keyboard, touchpad, battery, ram, and storage.
He figured out the traces on the motherboard which turn it on when shorted. The Hercules line features a couple of flavors of dual-core ARM chips. This system was laid out in an antique frame and hung on the wall. By using our website and services, you expressly agree to the placement of our performance, functionality and advertising cookies.
