Hi SZapatero,
as sidehack pointed, loneoceans used a different design on his later drivers, you may want to try.
His later drivers blog entries lack a scheme, but the same implementation can be seen on other drivers on this thread:

To save you work i´ve made a scheme i hope is correct:
EDIT: With this design you need Rfbt y Rfbb resistors, like in the boost scheme on your #8 post
