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. As of early 2015, 4.5 million of them had been sold and a second generation, the Raspberry Pi 2, has been introduced.

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.

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.

Looking for a free STL file to 3D print? These are the best websites where you can download free STL files for 3D printing. This is a selection of the best websites and content repositories offering 3D print files. Each lets you browse a large selection of printable models and download STL files for your own use. And they’re absolutely free. They won’t cost you a penny. Oh, did we mention that they’re free? Bonus: Some of these sites also include store-fronts for selling custom 3D print files. So, if you’re a 3D modeling enthusiast and fancy making some spare cash, these are perfect platforms for showcasing your work and selling it. Have we missed any of your favorite sites? Let us know in the comments, and we’ll add them in a future update. Free STL Files Download Site #1: Pinshape

KeyDuino - The quick & easy way to build NFC enabled things. The KeyDuino development board is Arduino compatible hardware and software.Since the KeyDuino is based on the Arduino Leonardo (ATMEGA32U4) anything that runs on an Arduino Leonardo will also run on a KeyDuino and this means whatever shield (with a few exceptions) work with an Arduino will also work with KeyDuino.

Hello everyone, Thanks very much for supporting us all the time. In order to provide better service for you, we count the fabrication time for the PCBs in the last two month. Here we release the lead time of 2 layer PCBs and hope this can help you.

The following exploded pie graph is the fabrication time proportion for 2 layer prototyping PCB fabrication. The PCBs fabricated in rush mode are not included.
