The Model B - which can be had for $35 in theUS, £27.44 in the UK, or AU$37.35 in Australia - adds an additional USB port, an Ethernet port, and doubles the memory to 512MB. The Retro Pie can work with either the $25 (£18.65 in the UK, and AU$28.50 in Australia) Raspberry Pi Model A or the slightly more expensive Model B, I recommend the latter. If this is your first time with the Raspberry Pi, I suggest you check out my earlier article for more information about the device. The project is a little difficult and requires you to input various lines of code, but you should be fine if you follow these directions. One of the coolest projects is called Retro Pie, which transforms the Raspberry Pi into a retro gaming console and gives you the ability to play classics like Super Mario Bros., Space Invaders, Sonic the Hedgehog, and many others. The low-cost microcomputer has been used to power home automation projects, servers, media centers, and many other do-it-yourself projects.
The projects people have created with the Raspberry Pi are truly incredible.
