I started the same... following schematics and stuff
then googled what were the components i used ... wiki is a very good start.
also looked to all the data sheets about those ic's i' was using
google again one link leading to another
Time much time reading
then i'll invite you to customize (bend) your existing designs
And start with a small project on your own and getting all the info you need asking precise questions on electro forums
burning a few fingers and components, crying
and then succeeding and moving to a bigger project
We always learn
have fun
