Another CDROM Controller Kit

[quadtech]

I checked the eagle files. The files as posted need
major cleanup/corrections.
I did fix some of the issues in my local copy, but
you (Holmes81) probably did all that already.

Does anyone know if this is still available???

 

[Jempie]

i have 3 kit available.

complete with LCD and manual, i have bought 5 pcs

Regards,

i will then try to load my hex file with the PicKit 2 thought ICSP Connection , it say error : "Programming failed at program memory address 0x000000".

Can someone help me ?

 

[Holmes81]

Ok,

Here is the updated Schematic in eagle format, I've not checked it yet so may have missed bits.

 

[quadtech]

I did a quick check and fixed missing IDE15 net, and also some fixed
ERC warnings. I am not too familiar with Eagle, so I lost some
of the nice LCD bus signal names you had.

Hi I just found this thread, and I read it with some interest as I have quite a few CD ROM's laying around.
I remember reading a similar project in Silicon Chip magazine, don't know if anybody is interested? Silicon Chip Online - Playback Adaptor For CD-ROM Drives

Cheers.. Steve

Holmes81, I verified the nets, and I think they all look good to me.
Nice work, sir!

 

[Holmes81]

nova_ck,

sounds like it might be an issue with code protection. If you have code protection on and try to verify it fails.

Have you programmed other hex files?

Also I've uploaded created another set of schematics, and separate PCBs due to using the free version of eagle cad. The idea behind separate schematics and pcbs is that you could leave out various parts, eg the IR part or mount the switch part futerher away etc.

As before they need to be verified by someone who has not spent ages looking at them!

I guess I need to read the whole thread.

Is anyone ordering boards?

tks.

 

[goldfinger2]

it very very very good project

 

[teetat]

Thank you so much

 

[Holmes81]

Ok ignore the schematic and pcb in post 149.

I've checked the schematic and tidyed the schematic up and added a few annotations.

Now I will start work on the pcb.

Use the schematic attached here.

thanks to quadtech for verifying the V4. If someone could check V5. (Should be final)

Thanks.

 

[quadtech]

OK, I compared V5 to the original, and it looks good.
Looking forward to the brd file

 

[Holmes81]

Still working on this board. It is a little more complicated than I though (well that's my excuse for being a bit rubbish at pcb layout!)

Watch this space as they say!

 

[Holmes81]

Quick update,

I've moved away from eagle to DesignSpark.

I now have the completed pcb layout in gerber form, which I am attempting to prototype!

Double sided diy pcb etching is a little tricky!

Keep watching this space!

Hi,

For the ones who are interested, here are my PCBs.
One for the controller, the other for the keyboard.

My project is fully working.

 

[cabest]

The PCBs were not attached...

 

[quadtech]

cabest, nice work.
What s.w did you use for the PCB? Can you
publish the PCB files? Or at least the pdf version and the
component layout?

 

[cabest]

The used software was wintypon.
No component layout was created : you have to take the schematics to mount the component on the board...
Not a problem, there are not so many components !

Good luck !
