What resources should the absolute beginner use to learn electrical engineering? How much would it cost to start up and teach yourself the basics? I've always wanted to start but I've never found the time until now.

To learn or to practice making shit?

There's berkley lectures on youtube.

mit 6002x has online lectures and tests

Both, but I would need to learn before I practice making shit.

You're making a 555 LED blinker as your first project? That's a good place to start I often recommend. What's with these cancel switches and operate switches? All three operarate switches would need to be pressed to do anything. Hitting any of the cancel switches or all at once will do the exact same thing.

No I just needed a picture to use for my post

In that case my advice to you is to build an astable 555 oscillator to blink an LED or make some square waves in a speaker. Its a great begginer project because you can add on to it once it's done.

You can use potentiometers to set variable speeds.

You can connect it to a MOSFET to make a really load noise or drive other large loads like high power leds or speed control motors.

You can use it as the clock signal for binary counters and shift registers and produce all kinds of creative patterns with LEDs.

As a little reminder: you can blink LEDs without any ICs. An astable using two transistors is one option.

Get The Art of Electronics, and an Arduino.

dude, that thing is obviously a coded keypad, where you need to press the 3 correct keys simultaneously, while pressing any other key would disable entry.

OP, if you just wanna build some sorta cool stuff, google "Electronics Lab 300-in-1" No calculus involved, just hands on stuff.

I already have an Electronics Learning Lab from radioshack laying around. Would that be just as good, or is the "Electronics Learning Lab 300-in-1" inherently better?

nope, it was just an example, they're all good. you can use the breadboard and onboard components to make many more circuits not included in the kit, so even a 100-project or 150-project lab is fine.
