Design Calculations for the Seasoned EE

Do seasoned designers tend to do a fair amount of calculations or are large parts of circuits designed intuitively? I'm asking because it seems like design engineers tend to have a sense of what value cap you want to have here, resistor there, for…

Reasoning behind "neutral pin nearest the edge" rule of thumb?

I've been told that there's a design rule of thumb that whenever you have a "bus" providing power and ground (for example, in an array of PWM outputs) that the ground connection is placed nearest the edge. What is the reasoning behind this?

Power plug orientation and usability

I was wondering what advantage is gained by modeling a power plug after the lower design. These are American power plugs, and they both exist. Perhaps the only consumer-based effect gained by using the upper plug is that the plug can be put in…

Embedded design flow

Sometimes I get unmotivated to finish my personal projects because of a lack of plan on what to do next--should I design a board first, hook up a test circuit, write test code or write design requirements? Are there any formal design flows maybe…

How do I power a device with a 4-directional 4-pin connector? I have an idea and I would like you to point out what's wrong with it

Let's say I have a matrix of square 12.7 mm cells. Every cell is a connector to which an independent little piece ("little piece" is a building block) may be connected. Actually, it's a little puzzle/sandbox game (a hobby project) where you have to…
