hey I know I shouldnt really be starting another project but its going to take a while before I get the parts to finish the other. But I found an old laptop and was wondering if I could use the hdd to make a mps player or the cd drive for a cd player or the ram for a mp3 or enything out of it to play my songs.
wo you want to use the old lappy parts to make a MP3 player? there was one there that can use them parts *hunts a link* http://www.pjrc.com/tech/mp3/ ... if thats what you meen?
for stand alone http://www.myplace.nu/mp3/ http://www.oryxmp3.com/ here is another figure I just use the parts for my project http://forums.bit-tech.net/showthread.php?t=87485 . Broke my laptop during a fight and I salvage what I could to make a media station. using hardrive and cdrw/dvd drive in silence of the fans and I am using the AMD 1400+ Atlon M CPU from the laptop in Hannibal a 1000GB storage server.
Cool, thanks I think I will try the yampp one. EDIT: Got a queastion for yampp3/usb what are the values of r1, r8, and a bunch of the capaciters? Never mind I found out. EDIT2: And the programing connector I understande programs it with the bootloader and firmware but is that connected to the pc through the serial and if so how? OR does it program all of it with usb...then why would it nead that programer socket? EDIT3: And I dont nead the reset key right unless I am going to change the bootloader and such. EDIT4: Would it work with a lcd screen that is 2 by 20?
It's not designed for an alphanumeric LCD, it uses a Nokia 3310 or 3315 LCD. The programming connector is a (sorta standard) AVR in-circuit programming interface, you'll need the appropriate programming hardware to connect it (to serial or USB or whatever) to program the microcontroller. It is possible to bootstrap an AVR to the parallel port for programming with no hardware.
No, if you look at the site it says "display connector for a standered lcd easily configurable." But how, I will probibly nead help programing this part. Also teh avr, I will search around on google. But I probibly wont find enything. So get a link ready. EDIT: Found it: http://medo.fov.uni-mb.si/mapp/uTools/uisp-parport-connect.txt
you are right "Theplayer have two different LCD interfaces. One is an interface for standard LCD displays with Hitachi HD44780 (or similar) controllers. Code is written for 2*16 and 4*20 size displays" If you know a bit of ASM it shouldn't be so difficult implement the LCD that you want. My opining,its a good project a bit dificult I have seen others that are more simple yet they support hard drive an ATAPI CDrom drives and you wouldn't go to that much trouble. If you really want to build it I mightbe able to help you all you have to do is ask.
Hey cool I will nead it. But before I start the programing part there is a hardware issue. When I when to order the atmega161 it said I should use the atmega162. Which should I use?
Mega162 is supported in native and compability mode just use the correct rom file in you case : y3_boot_M162_mode.rom or y3_boot_M162_mode.hex take a look at in the bootloader files and the firmware files it tells you how to set up the cpu.
I started looking for parts and added it all up, 30 BUCKS!!!!!! Well I guess thats the end of this project then. Unless you guys have eny other ideas. *Wonders off thinking.*
Ya but right now I am broke, besideds you can get a cd player for 10 dollers and burn your own music. Speaking of which could I use an old cd drive to make a cd player, that could read homeade cd-rws made with windows music player thingy that burns your music to cd's.
if the cd drive has buttons in front and the volume control yes all you need is to connected to a power source and connect a cable to the earphone connector and the other end to an amplifier(home sterio with aux inputs).
i have maded my own cd player out of an old asus cd. drive. it works and i have mounted window in the top cover. but gave it to my big brother. he smashed he's last cd player and was begging for it
Thanks I have a drive with all that stuff but could I do it with a laptop drive (smaller) thats doesnt have any of the buttons.
