Hi,
I attend to share this experience with all of you.
I've started to build my own CDplayer.
-It is based on the CDPRO2 mechanism of https://www.daisy-laser.com.
-I do not use the internal DAC of this unit, but I built a DAC with 2 TDA1541A in //,. The protocol of incoming digital data from the unit is I2S
The DAC is using the 6C45PI vaccum tube as output buffer.
- The controller is based on the PIC18F452. There is a LCD (4-Bits programmed), buttons, IR and DSA interfaces. The DSA protocol is used to receive/send data from the CDPRO2 unit. (take a look at the CDPRO2 datasheet)
- I built as well as PSU board as I need several voltages :
+5V for the DAC, controller, unit
-5V, -15V for the DAC
9V for the unit.
I didn't completed the PSU for the output buffer so far, let's be patient :wink:
You will find enclosed some schematics and boards.
The schematic of the controller board is still a "draft" as there remains several task to do, for example, dealing with the ON/OFF sequence of the CDplayer.
Tell me what do you think about htis project
