Home brew MP3 player. All we need now is for someone to make a cdr version instead of smartmedia (AIWA has one for the car).

Why does the bleeding thing look like someone took apart a toaster and stuck ear phone jacks inside? I thought these things were supposed to me more high tech and all that ?

Considering that it's homebrew, I'd say that even though ID expectations are low, the delivery is better than most homebrew work I've seen.

the outside looks ok, but the insides is what i'm talking about.

There's also the Brownworth Box, or Route66, a project to build a lite PC running Linux that can be an in-car MP3 player. Tiaka, all electronics look like that naked, sheesh. It's just a breadboard. The top picture shows a case with a manga image.

yes, but my name is felix, whatever. I know that's how everything looks underneath, but i would imagine this being more complex somehow, take apart my 2 year old walk-man, it looks more advanced. I think the player itself is great sure, if it works it works and all that sorta stuff, i was just commenting on my views. is all.

James, this is a good guide for mp3-playing hardware. There's 71 entries just in the portables section, several working off off CDR, like the MomboX and the D'Music. These are all commercial, though, I don't know if you meant homebrew specifically.

All it is is a circuit board and a memory card. That's the least-possible high-tech looking kind of tech stuff you can get, really. It's simplicity, and non-descript techiness design are what make it really really elegant, in my mind. :-)

The reason why your walkman looks more "advanced" is that it is wildly cost-reduced. Cost-reduced means that if they disocvered that using 6 transistors costs less than an integrated op-amp, they will use transistors (individual transistors are something like $0.04 in bulk and a dual op-amp will be like $.40). If they use the flat-pack models, you'll get that slim low-profile look. I think its cool that he managed a 3 chip solution. Further, the Atmel chip is $7 (although in bulk, that's probably more like $5), the Micronas chips are butt-expensive in small quantities (mostly to discourage this type of work or for them to make up money on the support sink they'll have as a result of doing small quantities), but I'd expect that they'd be $15 in bulk. The rest is about $5, so you're looking at $25 in parts, give or take $5. Not bad.
