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- ...
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 ...
