Title: Schematic for "Multi-CD" emulator Post by: spumanti on 08 Feb 2005, 15:36 Hi vitat! :p
I would like to make my own layout for the emulator (for connecting yampp3 and pioneer hu). I saw that you made a PCB layout for the system, http://www.vitat.spb.ru/forum/index.php/topic,27.0.html, but the IC's and the controller I have are not SMD size, so I can't use your layout. I was wondering if i could get a copy of the scematic for the "Multi-CD" emulator either for Eagle or Orcad, or even better, if you had a PCB layout for ordinary (big) size IC's! Thanx in advance!

I have now made a layout for the multi cd emulator in Eagle. It seems to be OK, but I am not very good at making layouts, so it will be interesting to see if it works when I get it soldered!!! (just waiting to get the PCB etched). I packed the Eagle project files down in a .zip file if anybody is interested. Just unzip the file to your \EAGLE\Projects folder, and you'll be able to see the layout. Eagle demoversion can be downloaded from: http://www.cadsoft.de Hope it is useful!

Title: Re: Schematic for "Multi-CD" emulator Post by: spumanti on 11 Feb 2005, 10:58 Yes, you are right Vitat!... bummer! :(
But it's not on your schematic either!!! I'll see if i can corerct it (when I have time).

I'll post the revised Eagle project on monday. Have a good weekend 8) Title: Re: Schematic for "Multi-CD" emulator Post by: Vitat on 12 Feb 2005, 14:23 I have made my the schematic in Eagle for DIP packages.
PCB don't finished. Title: Re: Schematic for "Multi-CD" emulator Post by: spumanti on 15 Feb 2005, 14:42 I changed the PCB so there's a pullup resistor on the reset pin on the ATmega8.
Got the PCB etched as well. Attached is the updated Eagle project |
