A tiny sound card based on the Covox Speech Thing design. I have another design which adds on an LM386 amplifier which can be found here.
##PCB Design software and addons used
- Eagle 7.5.0: I use Standard but Light should still be able to open/modify the files.
Due to my oversight, only the DB25 pin 19 is grounded whearas the standard calls for pins 18-25 to be done so. You might need to modify the design if you face problems.
##Schematic drawings Images are exported from Eagle at 600dpi.
