Not all electronic signals are communicated via electricity. By transmitting information in the form of light, we can avoid many limitations inherent to traditional wiring. And on top of all that – fiber optics are just straight-up cool!
Easily overlooked, but elemental to electronics hardware, the manually operated switch is the simplest of electromechanical devices — and likely the most familiar. While the most basic switch is … well, quite basic — there’s a crazy-huge variety of switch types & sizes available to the electronics maker nowadays. Those new to the soldering & schematics scene will surely benefit from an introduction to some of the terms and formats relevant to various switch species.

Another clever trick from the world of electronics — Pulse Width Modulation is a simple method for controlling analog devices via a digital signal. It’s also an efficient way to drive motors, lamps, LEDs, and more.
Collin explains Pulse Width Modulation, a simple method for controlling analog devices via a digital signal.
Ever wonder why they call it an electronics “breadboard”? It’s time we try building on a *real* breadboard.
5mm or 10mm LEDs will work just fine for most projects, but if you really want to light up a room, consider using some of the high-power variety. With forward currents up to a full amp, you’ll need a way to dissipate heat – but the results are very much worth the extra effort.
Every useful electronics project deserves a good enclosure. Providing a proper case for your circuit can protect it from accidental spills & falls – plus give it a cool look you can proudly show off to those unfamiliar with soldering and such.
Follow along with Collin as he turns a barebones function generator kit into a sturdy and versatile tone-box fit for noise-jamming & testing purposes. Get more info and a parts bundle: http://blog.makezine.com/archive/2010/04/circuit_skills_electronics_enlosure.html
