IDE CD player through PIC - Page 2 - Electronic Circuits Projects Diagrams Free

Point is that the project can be done but it's a fairly advanced project either way. The SD card has no audio and you'd need to build an MP3 decoder (SOIC too).
Try a simple project, get your feet wet. Flash some LEDs then build a clock. The IDE drive would be an easier project but difficult as it's no longer a popular project. The links futz posted contains most of the info you'd need to begin, but you're going to have to understand how IDE works first. You still need a power supply, are you going to use a nice noisy PC supply to run it. ATX supplies you'll have to mod the ATX cable to turn it on & off.
Why don't you try building and programming the "Magic lamps" from the other thread first.

I'v already written a binary clock, led flasher, and a program that deals with weird numbers. I am having all sorts of trouble JUST getting a pc to program my pic, I need to have 12v to enter HVP (JDM) and I only have one computer that can do it, but, on that computer I can't format the hard drive for win98, (I am using the startup floppy) my drive is 20 gigs and Fdisk insists that it is 7 mb, and making a partition results in a 7 mb disk. If I can get this computer to work, I already have my hex files, I should be good to go.

I will write the code for my "MicroMagic Switchboard"

I'v tried multiple HDs, still 7mb.

Ok here's a project for you and it's an excellent one IMO.
A PICkit2 as writing any complex code for a PIC is much easier with a debugger and a proper programmer.
I've built my first one by hand, then I turned it into a kit. The manual on my site includes the schematic and the firmware is part of MPLAB or PICkit 2 software and you can use your JDM to program it initially.

The Junebug PK2SE prototype.

It does, but you still have to read the TOC off the disc.

Bill, will it work with a Mac? Or do I still need my pc laptop?

Silicon Chip magazine in Australia just published a project that interfaces a uC to an IDE CDROM to play audio disks. It includes an LCD display to indicate what it's doing (track, time index etc.)

Here's the link:

Can't remember if it uses a PIC, but it does show you how it's done.

Hey everybody I have success!

I sacrificed a CD ROM Drive to discover that it has no amplifier inside, so all you have to do is:

1. Find a few CD ROM Drives (not all of them will work)
2. Have them standalone (by themself)
3. Connect up amplifier (an absolute necesity) with speakers. Must have own power supply
4. Connect up 12v and 5V connections
5. Press play, hopefully it should work!

Good luck!

Also, very efficent headphones will work (Like the .1 amp headphones, mine cost 50+ dollars so grab good ones

)

XP or Vista 32bit

Problem is CD players are a dime a dozen, some cost less than a PIC.
Now a networked MP3 player like the Squeezebox was originally based on a PIC16F877 would be nice project. Too bad that 40x2 VFD display is $90
