Introduction In a previous blog, there was a project for complete beginners, to draw a tree with zero programming experience required. In this blog post, we go 3D. Again, no programming experience is needed to follow this project and extend it to draw different 3D objects. We will also rotate objects.   Designing the Tree First off, a tree was sketched on graph paper. It was decided that the origin (0,0) point would be at the bottom of the tree, so that the base of the tree trunk has co- ...

The Secret Life of the Pi

Posted by shabaz Top Member Jul 15, 2017
Introduction If you’ve ever wondered how the Pi functions internally, the answer will really depend on how deep you want to examine it. Each part on the circuit board has documentation, sometimes running to thousands of pages. I wanted to explore it at a higher level, but still detailed enough to begin to understand how the Pi functions when computer code is executed. The diagrams and explanations here are not 100% accurate (and the Pi probably does not have little robots inside it as show ...
Introduction I’m lucky to know lots of very creative and thoughtful people here at Element14, and in my everyday work and play. I spend as much time with them as possible because I learn so much.   If I throw out a problem at people I’ll inevitably get back some possible solutions, and I then use some engineering experience to convert it into a physical project. Engineers love to problem-solve, and they love to create things. If you’re lucky enough to be able to come up w ...
Introduction This blog post contains some miscellaneous topics that are handy when working with the Pi. It covers how to enable the wireless capability on the Pi, how to get started attaching your own circuits to the Pi, and a command line guide.   Use this blog post as a quick reference to do these ‘things’:   Enabling Wireless (WiFi) connections Connecting Input/Output devices to the Expansion Header Quick Linux Reference Guide Powering off the Pi   Enabling Wi ...
Introduction This blog post has a collection of steps or ‘things’ that can be done with the Pi in order to be able to access it flexibly. These steps allow you to work with the Pi either using a keyboard/mouse/TV or using your desktop PC or laptop and remotely connecting to the Pi.   The key steps are listed and all the links to click on for more information on topics. Not everything here is essential; it is more a la carte so you can pick and choose.   Use this blog pos ...
Introduction This blog post contains information on some of the important steps worth taking if you've purchased a Pi and are getting ready to set it up all ready for creating projects. It covers the practical points up to installing a fresh copy of Raspbian.   The key steps are listed and all the links to click on for more information on topics.   The bare essential things needed are: A Raspberry Pi (for example the Pi 3, but earlier models will work too) USB power supply (if yo ...
