>Project Idea :-  Water  Mixer  Controller  (Temperature)

Haha, how very funny.  I developed this idea about 7 or 8 years ago.  Lost
interest due to many complications, most of which I don't even remember at
this point.  Was a great idea at the time... probably still is.  I think at
the time, availability of electronic solenoid valves for flow control were
tough to find, and expensive.  I think that was the main problem, along with
installation or retrofit problems.  It would be tough for the average user
to install it behind his/her shower after the fact.

Besides, people don't pay more than $20-$30 for a showerhead nowadays
anyways, and this would certainly double or triple that figure, or even more
for a commercially available product if you expect to many any money on it.
People just don't want to pay that if they can just turn a knob and get
"close" to what they want... for the 15 minutes they're in the shower, this
is sufficient for most.

Of course, there are people (like me) who would want complete control and a
nice constant temperature throughout the entire shower cycle.  But even I
learned to live with tweaking the knob every 5 minutes or so if it cooled
off.

Good luck with it if you persue it.
