Hearing people talk about their passions is one of the best things in life

It’s very depressing to ask someone about their weekend and the answer is always nothing more than TV and sleep.

I know somebody who maintains a gas powered go kart that his son races with. I don’t know much about it, and I’d never be into it, but at least hearing about what he is up to is interesting.

Some model trains operate on a system called DCC, or Digital Command Control. As an alternative to DC, or Direct Current-driven models, it’s a commonly-held misconception that DCC runs on an AC, or Alternating Current circuit. In reality, it’s still using direct current, but combining it with PWM, or Pulse Width Modulation, to embed digital signals at slightly higher voltages than the regular operating voltage. These signals can be used to address individual models and send commands that allow for a model to have more functions than a DC model would be capable of, such as more sophisticated lighting, finer motor controls, sound features, consists, speed matching, automation, and a lot more.
