The best place to learn circuitry?

Name: Anonymous 2010-06-15 21:57

So, /sci/, maybe you can help me.

I want to learn electrical engineering. Not theory so much as practical info. My ultimate end goal is to build my own UHF transmitter.

Here's the thing; I'm starting from scratch. I didn't pay attention in high school and majored in liberal arts in college so while I know the absolute basics, anything beyond that is shit I'm gonna have to learn.

I know it's going to take a while to work my way up to a suitable knowledge of EE, but if any of you know a good site/resource to start with that would be most helpful (preferably with a tilt to radio and TV circuitry).

tl;dr: Give me a good place to learn electrical engineering

I dont know any websites as such but you could start off taking apart simple devices and looking at the circuits. Also How much do you actually know?

A good place to start might be a book called The Art of Electronics, Anon.

build an ELF receiver and listen to the earth singing

already done.
It's called a seismometer.

When it comes to circuitry, I know there are at least four types of circuits. The first two are tier one, the last two are tier two.

Series circuit (tier 1) which leads from the negative lead of a power-source through the circuit in one line back into the positive lead.

Parallel circuit (tier 1) which leads from the negative lead of a power-source through the circuit, but has two or more branched lines which lead back to the positive lead.

Combinatorial circuit (tier 2) which is a "combination" of a parallel AND series circuit for use in digital products and electronic algorithms. (motherboards)

Integrated circuit (tier 2) which is an entire set of circuits integrated into one solid-state device. (micro-chips)

Just wait till you get into the difference between electrical-integrated circuits and photonic-integrated circuits. XD

So, that should give you a head's up.

unlike lazy mcArtMajor I'm currently a computer science major with a strong physics background.  i was great at mechanics(physics 1), and good with initial electrical stuff, but about the time we got to the Biot-Savart law, and Gauss's law(read: the mostly calculus stuff) the class started to move too fast for me, I wound up B in physics 2.
I've managed to solve a few electrical real life problems, mostly with things that can run on 12v DC(since that's what car batteries and PSUs supply).  But I've kept my physics book, thumbed through it, and decided i want to properly learn this stuff, so I'm looking at it on my own at my own pace.  The field stuff is fine, but i did pretty good with the elementary circuit stuff(kichoff's loop rule is my bitch).
Anyway, I've been thinking of getting a multimeter and, if available, a kind of teach yourself book that would provide instructions and simple circuits to built small, useless gadgets.  Any recommendations(on both book and multimeter).
One of my goals right now is an induction coil so i can melt various metals and try my hand at casting things from molds.

If you don't want to learn theory, then you can't learn electrical engineering.  You should say you want to learn electronics.

Lecture Series on Basic Electronics by Prof. T.S.Natarajan, Department of physics, IIT Madras:

There are tons of UHF transmitter circuits online.

the best way to learn circuitry is to stick something metallic in a socket.

Don't change these.
