What about a thin cork board, making holes (that go from one side to the other) for the pins of the chips, pushing the chips into the places I've made for them, then wedging the ends of the wire into the underside of the cork so they make contact with the pins without any soldering?
Also, would I get some sort of result by doing this, I know it won't mean I have anything functional, but if I found the correct ICs and so forth, connected them up, find out it doesn't work, how 'dead' would the whole thing be? Am I making any sense whatsoever?

High-level analogies of things are perfectly okay, but I get the impression kids today are being taught some very skewed views on things...
You'd be surprised, and very saddened, by what passes for education out there.

Unfortunately I don't have a whole lot of cash to spare on experimenting, I'll look into your suggesting though.
Thanks again!
You might find more stuff if you research HAM radios.
The day of the electronics hobbyist is dead and gone, I'm afraid. You missed it by a couple decades. In fact, I think the advent of the PC by IBM signalled the beginning of the end.
I see it all around... everything is microchips and disposable circuit boards... technicians nowadays are becoming more and more like "pop and swap" artists than electrical mechanics anymore... it's very sad.
Here's your chance to shine, though... be the guy who writes the step-by-step guide

There uses to be TONS of electronic hobby books in the 50s, 60s, and somewhat into the 70s.. byt the 80, itswas just about dead. Heathkit used to be the premiere enthusiast company- you could build your own TV (I did!). Nowadays, best bet is rummaging through thrift stores and looking for local electronics hobby shops- most cities have at least one. you also might be able to swing by a mom-n-pop TV repair shop to get some tech info, but for the most part, the jump from transistorized electronics to IC based is big, even though ICs are essentially just a mass of Transistors.
Radio Shack used to carry IC tinkering hobby books. I still have my 555 manual somewhere. I even have an 8088 book my father gave me. He was an ET back when ETs FIXED circuit boards, not swapped them. Might wanna chekc your local library, and look in encyclopedias from the 60s and 70s. another source would be (hard-to-find) issues of Electronics Illustrated and older (early 80s and earlier) issues of Popular Electronics. this will give you the background. there are some hobby-modding sites online where you can 'mod' things like neo-pets, sumo-bots, and shit like that.
Essentially, best bet is taking some courses at either a local electronics trade school or some bonafide EE classes.

Ancient, but interesting.
too bad its not cost effective to make that. i would have liked to make a nice mp3 player which takes up any sd card i have - i have quite a few of them. .
and breadboards are great for beta testing a circuit.
then you get those "breadboards" with holes in them to make a prototype.
then you get a pcb.
but its quite costly to make virtually anything. only really simple circuits are "cost effective". the only thing that was ever cost effective for me was a fan controller - which consisted of a 2$ rheostat instead of being a 25$ front bay fan controller. Obviously it wasnt a PWM 4 fan with lcd and shiny butons controller, but it worked and didnt eat up a whole 5 1/4 inch bay.

Hi there,
I am in a similar situation that u in. Have you gotten help? I am also doing an MP3 Player project.

Here's the situation!
I've built my own pc, no biggie. I fully understand what a leap building a portable mp3 player from that would be. I know java, but I wouldn't consider myself a coder, that is, my job is and never has been that of a programmer, its merely something I'm interested in, and apart from a silly applet or application or two, I've not programmed a full application.
Okay, now, I've got a whole bunch of questions, firstly, how hard?
Secondly, what does the PCB board do. Now, I know you're probably thinking "this guy hasn't got a clue, best tell him to give up" but I'd really appreciate answers just for curiosity's sake. I've got a schematic and PCB designing program, I've found a good company that will manufacture one PCB board for me. The thing is, what does the circuitry need to do? Just link up the ICs? What about capacitors? Obviously I realise I also need to use the circuitry to ground stuff and actually supply power to stuff!
Okay, ICs, I've found a couple of MP3 decoding chips, the thing is, is there anywhere that reviews this stuff? Also, I've looked at the datasheets, but as I'm sure you are aware its important I know the size of the things and so forth before I even start to draw up the PCB schematics.
Basically, what do I need? What ICs do I need? Is it a case of connecting them up? Am I being incredibly naive? I honestly don't even know how to find the stuff I need.
The datasheets do tell me alot of what goes to what, and I suppose I could get all the chips from the one company, hopefully.
Also, lets say I've soldered everything somehow and all is okay, then what? Do these things have some functionality without me doing anything else? I mean, forgetting about input devices and whatnot, well, a play button, what exactly 'tells' the flash card controller to send the stuff to the mp3 decoder and then out to the bit that converts it into an analog signal and sends it off to the headphone jack?
Don't laugh, I may sound like a fish out of water... or a hedgehog shoved in the deep end... but humour me, cos I'd really appreciate some answers!
