Title: Capacitors, Resistors, Transistors: Where to start?
Post by: VegaObscura on June 24, 2009, 08:32:44 AM
I want to learn about all those tiny little components that are in all things electronic.  I know very little about them.  And I don't want to just know what they do, I want to be able to USE them.  Recently I took an old toy robot that I got for christmas and decided to play around with him.  He was a $15 robot, made for fighting others like him.  Well I lost the controller about a week after I got him.  I put him in the top of a closet hoping I would find the controller and be able to play with him again.  2 years passed and finally I decided I wasn't going to find that controller, so I took him down and took him apart.  He had various PCBs and a couple of IR receivers to pick up the remote control.  I took almost everything out, leaving only the motors, gears, and wheels.  I wired up his battery compartment straight to one of the leads of his motors, the other to his on/off switch, and finally wired his on/off switch to the other motor lead.  I was pretty satisfied, and turning the switch on would make him go straight forward.  Unfortunately, that's about the limit of my knowledge and abilities right now.  I know how to solder.  I know how to connect a battery to a component.  That's about it.  Now I want to learn all about transistors, capacitors, semi-conductors, resistors, microcontrollers, and all those fun little things.  I want to know where to learn those things.  My budget is absolutely nothing, and all parts that I use must be taken from old electronics.  Fortunately I have lots of those, and most of them are broken so I can take all the little parts out I want.  I do not yet own a multimeter.  I want to be able to actually take a part, put it in a circuit, and see it make a difference to the circuit.  I don't need anything useful, just so I can really see what every part does and learn what they're used for.

Try to find a few books at your local library:

well, take a look at the $50 robot tutorial, it may be $50 but the knowledge is priceless!

Unfortunately the $50 robot tutorial does not cover most of the general electronics.

some good books if you are in Australia are the Funway series it has 40 projects all together and are available at dicksmith and its how i got started in all this.
