How to deal with envy?
I have several character flaws, and I'm trying to work on them to improve myself as a person. One of the worst flaws I have is a severe, debilitating form of envy.
I envy one's possessions, experiences, and physical traits. It's quite pathetic, really.
But I can't control it. The envy is so strong it's enough to knock down my mood for a couple of days. It will make me moody, passive-aggressive, depressed. I hate feeling like that. Any tips on how to deal with this?

Sup guys. I was wondering if it is possible to build a buck converter to transform the 120v from the wall outlet into a lower dc voltage so I could power a wide variety of equipaments. Like a simple variable power supply. Without the use of a transformer.

I'm new at this. I'd like to know a simple method to output a PWM controlled signal out the TL494 chip. Do I really need a reference voltage? Can someone walk me step by step?
4 AnswersEngineering7 years agoWhat determines the current capability of a transformer?
Think of a step down transformer, 120v to 12v.
Some of them can give you 1 amp, 2amps, 5 amps and so on. What is the difference between them?
