The DIY dream
Raspberry Pi — a tiny, stripped-down $35 computer — hit the market in 2011 with the intention of helping promote basic computer science skills in schools. It has become the DIY gadget-maker's go-to device. Tinkerers, hobbyists, educators and students — basically anyone who likes to build things — have taken to the Internet with project after project utilizing the Raspberry Pi.
In early 2015, a second generation, the Raspberry Pi 2, was introduced. And now it celebrates another milestone: 10 million units sold. To mark the occasion, the Raspberry Pi Foundation has launched a "Pi-in-a-Box" starter kit to get even more of us to learn about and use the low-cost computer. It'll go on sale in the U.K. for £99 and hit other markets soon.
The little computer has controlled robots, reached the upper atmosphere in a weather balloon and become the building block for almost any gadget the mind could dream up. With all of the builds out there, it can be overwhelming, but don't worry, we've done the hard work for you. Here are 20 of the best Raspberry Pi projects on the Web.
