How do I apply math to electronics? - Page 10

duragrip · October 12th, 2015, 11:46 AM

Where does the motivation for assembling circuits come from? For me I think it must start with the question, "What's the point? Why should I care? What's it good for? How is this circuit interesting to me?" Until I can find the answers to these questions, I won't feel motivated to make circuits. I don't think I'm the type of person who can do things unless what I'm doing has some basis in reality to me. I did not do my homework in school because the problems they were presenting to me did not have any personal, emotional connection or relevance to me. Where can I find those circuits that will capture my imagination and give me the desire to understand and build them?

This is the classic excuse for not doing your homework. Just do it because you have to and stop whinging!

Seriously though, the reason why these things are important is right in front of you. Literally. How do you think the power button on your monitor/screen works?

Here's my advice:
- if you're doing science/maths for work, just get it done.
- if you're doing science/maths for fun in your spare time, then find something you are passionate about and then do that instead. If you need someone spell out for you why it's important and why you should be spending your time doing it, then simply do something else; it should be obvious whether something is worth doing or not.

Maybe I'm a software guy.

Is it as satisfying to program a microcontroller to do what I want.

Only you can answer that.

My electronics labs will belong to my Batman figure. He'll be my hardware guy. I will be focus on testing software.

Do smart cars drive themselves? Are they like smart phones?

I'd like to know how 555 Timer works like the back of my hand. You have 3 5k resistors, a comparator, a flip-flop. You need a capacitor, a couple of more resistors to bias the transistor. I need to know how to create monostable and astable effects, and what they're good for toyetically.

On the previous page in this thread, I posted a link to 555 circuits, there's a lot of examples of what you can do with them.

Smart cars (the brand) or Smart cars (autonomous vehicles)? Neither are like smart phones.
To be honest, I've never liked the phrase smart phone, there's nothing smart about them.

The 555 timer is a cool toy. I'm analyzing it's internal components, to make building circuits more satisfying.
