electronic speed control

Ideas for motor speed control

I have an idea of how to do a electronic speed control for some DC motor (H-bridges).
I built this circuit and it works pretty well.  Its a PWM generator based on this great tutorial .  I had to convert it to a NE556 instead of a NE555 but it works well with a 100K linear pot..
