Looks like VFD, but schematic says LCD. Anyone have a part number or description of that technology?

Thanks,

Sounds like we have some more interest in this project.

Any concensus on how the control board/buttons should be done? I see two options:

Option A:
Click the image to open in full size.
seperate buttons board

Option B:
Click the image to open in full size.
buttons integrated with display pcb

For option B, it could be done as to allow the pcb to be trimmed and an expansion header installed for the buttons, thus allowing option A to be added if later desired.

I would like to keep this first run limited to 10-15 boards, as this is just the initial stage of the project, and I would like to see it improved on and another run of boards done.

As for what could be provided with this project:
- pcb set for control board and buttons board
- pre-programmed PIC18F452 chip with socket
- crystal oscillator for PIC along with caps
- RS232 chip with socket and caps needed
- serial connector for side of board

Another option for this project would to put a 5v regulator on the control board (would only make it a bit wider).

Please provide input, and we can work together to evolve this into a complete project.

Schematics and layout for boards I got made for my school project:
http://www.briangt.com/gallery/cdpro2-pcb

There are some mistakes in the layout, which I will correct:
-wrong footprint for pot, causing them to have to be mounted like this
-incorrect silkscreen for a couple of labels on the output pins (reversed labels for IR and Buttons headers)
-misaligned headers connecting to LCD, see this again.

These problems can easily be fixed and more features added.

As for the power supply, I foresee eventually making a pcb for the +5,+9 needed for the transport and also for the +5 for the control board, along with relays for proper power up on the +5 and +9 for the transport.

For those who missed the earlier post, see the first post for the current C code for this project.

Here is a quick assembly guide that I made for this project, for the kits that I mailed Peter Daniel and Anthony:
http://brian.prohosting.com/assembly/
note: these instructions account for the errors in the layout, which will be corrected before any more boards are made.

Wiki for expressing interest in this project:
http://www.diyaudio.com/wiki/index.php?page=cdpro2

I will not be providing cdpro2 units, as they can easily be purchased in the US from ENCO Group:
http://www.enco-group.com
or in Europe from Nico:
http://www.daisy-laser.nl/homeoptics/

Please note that if you want a fully functional kit, Nico is currently offering one on the above website.

Also, the control board/button board for this project isn't strictly limited to the cdpro2. It is essentially a PIC18F452 development board, which could be used for many other tasks, such as controlling a volume control like the APOX units did. My intent is not to compete with the APOX units, but provide an open source development environment for the cdpro2 and other projects.

Good picture of current control board layout:

Any input is appreciated.

Hi all,
I'll tell you what I really like the sound of is a single optical encoder (as you've made provisions for on your board). That gives you:

Play / Pause
Next / Prev track (if you click it slowly)
Search Back / Forwards (if you twist it fast)

It requires interrupts but you have also done that so it should be possible.
