Hi,
I'm a student in EE, I wanted to make my own design, of the drawdio project.
The makezine project page is here : http://makezine.com/projects/drawdio-musical-pencil/
The project is a signal generator, wich then will be amplified and then send through a speaker, as the frequence changes in fonction of the resistance, by changing it you can generate differents sounds.
I need your help, please, because i made an eagle design, then made a pcb from it, but it doesn't work and I absolutly don't know How and what can i do to make it work or to debug it ! I'm stuck at the point of not even knowing what could possibly can be wrong.
Every thing is open source, open hardware :
Here are images of the circuit :

Here is a PCB :
