The price per gigahash these days is shocking considering what the original ASICs fetched per gig/hash. If I had one regret, it was making a preorder from Butterfly Labs back when instead of keeping the coinage I spent on it.
21 Bitcoin Computer - the Macintosh of Bitcoin
Since guessing the business model of 21 Inc seems to have been everyone's favourite activity over the past six months, let's not waste any more time and dig right in.
First of all, we've got some photos of the actual machine. The packaging looks good, the mining component of the device looks sleek and elegant, while the actual computer is a standard Raspberry Pi 2, according to the FAQ.
The 21 Computer's mining chip spec appears to be 0.16 Joules per Gigahash,50 Gigahashes per second. At the moment there doesn't appear to be any upgrade / swap options for the machine.
This seems to put it in the same category as the Antminer U3 Batch 2 - currently selling for $20 and clocking in at 63GH/s. Comparing it to existing solutions, the energy efficiency seems rather odd. It appears to be roughly 6250 MHash/J, while the top performing AntMiner S7 comes in around 4000 MHash/J. This would seem to suggest the chip is underclocked to be more efficient.
The value of the whole package come in a little under US$100, with the Rapsberry Pi 2 along with all the extras selling for about $70 at the moment. But, the hardware isn't everything, so let's look at what else we get with the 21 Computer.
