thomaspfeifer.net - Elektronik und AVR-Projekte, SMD löten, Tipps & Tricks zum Platinen herstellen Online | Reuben Margolin’s Kinetic Wave Sculptures Our Mechanics theme brought to mind San Francisco Bay Area kinetic sculptor Reuben Margolin, one of my all-time favorite artists. He makes mind-blowing, moving art based on tiny observations in nature. His collection of waves has the ability to quiet, soothe, and inspire awe in the viewer. Margolin combines math and simple materials (and insanely neat string and pulley systems) to recreate and amplify subtle effects that often go unnoticed in nature, like a tiny ripple or the movement of a caterpillar. One of my favorite Make: television segments is this fascinating 10-minute profile of Margolin: Goli Mohammadi I’m senior editor at MAKE and have worked on MAKE magazine since the first issue. The maker movement provides me with endless inspiration, and I love shining light on the incredible makers in our community. Contact me at goli (at) makermedia (dot) com. Related

Aerospace Digital Library NEETS - HvWiki From HvWiki NEETS is an acronym for United States Navy Electricity & Electronics Training Series. The NEETS series consists of 24 modules, each covering a specific topic in the field of electricity and electronics. Because it is a work of the US government and therefore in the Public Domain, contents of the NEETS documents may be copied verbatim without restriction. Purpose The Navy Electricity and Electronics Training Series (NEETS) was developed for use by personnel in many electrical and electronic related Navy careers. The series is designed to give small amounts of information that can be easily digested before advancing further into the more complex material. Contents Module 1 - Introduction to Matter, Energy and Direct Current introduces the course with a short history of electricity and electronics and proceeds into the characteristics of matter, energy, and direct current (DC). Module 8 - Introduction to Amplifiers Module 9 - Introduction to Wave-Generation and Wave-Shaping Circuits
Homebrew CPU Circuit Simulator Applet This is an electronic circuit simulator. When the applet starts up you will see an animated schematic of a simple LRC circuit. The green color indicates positive voltage. The gray color indicates ground. A red color indicates negative voltage. To turn a switch on or off, just click on it. The "Circuits" menu contains a lot of sample circuits for you to try. Full Screen version. Directions. Standalone (offline) versions. Index of Circuit Examples.
Simple mechanisms explained Email Below you’ll find animated diagrams and explanations of how various mechanisms work. Some of these have been crucial to major evolutions in mechanisms and technology, and allow us to do anything from fire weaponry to make cars move with the press of a pedal. Maltese Cross mechanism powers second hand movement in the clock: Radial engines are used in aircraft. Today, however, most aircraft use turbine engines: Reciprocating movements power steam engines in locomotives: Sewing machine: Manual transmission mechanism, also known as “stick shift” is used to change gears in vehicles: This mechanism is called constant-velocity joint and is used in front-wheel drive vehicles: Torpedo-boat destroyer system is used to destroy fleet in naval military operations: The Wankel engine is a type of internal combustion engine which uses a rotary design to convert pressure into a rotating motion instead of using reciprocating pistons: + Bonus – mechanism you can watch forever Leave your comment:
