my avr based mp3 player.. not yet finished..
based on a mega16 and a vs1001k with a 16x2 lcd

Sweet!

Do you have a website for the project so I can keep posted?
>> Anonymous
when its finished ill prolly post it on avrfreaks and here again, and prolly on the Technology board

Nice work.

just fucked up my mega16, now using a at90s8515...
i need to borrow a stk500 at school and high-voltage program the fusebits on my mega16.

i will noon begin to soldier the vs1001k

's cool and all, but you seriously need to work on your breadboarding technique. What frequency are you running at? Have you scoped it and looked at all the crosstalk and ringing.

Also, PROTIP: use more than one wire color. You'll see why after you board up your first big project, and need to find your first accidental crossover.

Also, what's the little surface mount sub-board conversion at the bottom left with the red LED? I'm guessing it's a communication signal level converter - probably RS232 since it doesn't look like USB, but I'm too lazy to look it up. What about the other completely unidentifiable surface mount hashup at the bottom right with the green LED that's hidden under all its wires and low contrast photography?

You writing your own mp3 code, or just porting someone else's?

Finally, this is a comple enough circuit to just etch out a dual layer circuit board so you can concentrate on getting your code right and not troubleshooting your breadboard.

Someone who cares, thats nice :-D (me so happy)
Yes, the vero with a red led is a ADM207 (RS232 converter)
And the one with the green led is a 3.3v to 5v logic converter that i need for the vs1001k.

And yes, I have scoped the signal from my programmer to my mega16, and its not perfect, but i dont have any other programmer, and it has worked for my needs upontill now. but the thing is that i programmed the fusebits in a way that i can't give it a clocksignal.. but ill fix that with a stk500..

the current 8515 is running at 12Mhz, i know, a bit overclocked, but i dont have any 8Mhz crystals right now.

since i only have 2 colors of wire ill take my chances with the red one :-P

and i have no tools for etching a dublesided board, infact i have never etched a board b4.. but ill do it when i get this to work.

and yes this is my own build.

More questions:

Where's the vs1001k? I don't see it on the breadboard. Also, what made you decide to go with the hardware mp3 decoder instead of a software solution on the controller? I'm not positive, but I think there are avr based controllers that are beefy enough to decode an mp3 stream.

More answers:
I dont think that this avr, clocked at 8Mhz, will be abel to decode an mp3 stream, read data from some sort of storage, display the info on the LCD and mabye even decode an IR signal.
And i sampeld the vs1001ks so they are free for me. And yes, there is no vs1001k in the current picture, i havent had time to make a board for it yet. will prolly happen today.

Slow progress... now soldering the vs1001k
