I can hardly imagine an electronics enthusiast without some sort of test bench. This can be as simple as a folding table and a couple of hand tools, along with a cheap DMM (Digital MultiMeter). Or, it can be as elaborate as a spare room just loaded with TE and a full complement of tools and accessories to go with it.
Many techs of yesteryear built their projects on a breadboard, then would transfer everything to a mirror copper clad board. Here's everything you need to know to use this timeless technique to wire up circuits for prototyping or functional applications.
Perhaps one day soon we’ll have a battery that displays no “memory” effect; can be completely discharged or overcharged without harm; and require no complex computerized management system. Does such a battery sound like too much to hope for? Thomas Edison didn’t think so.
Not every application needs a microcontroller, yet often times they're used in a project unnecessarily. I’ll show you two examples of circuits that don't use a micro, but are often built with one, and explain some of the logic and theory behind these circuits.
