Digital Clock with Seven segment display

[hardik.patel]

In digital clock i included a date (like..15:02:2014) & Time (like,, 06:33:54) and 2 digit for temperature in seven segment display.

Other than above feature what should I add to it.

Kindly suggest me some cheapest idea to improve my future product.

Use a digital sensor like DS18B20

DS18B20 is much expensive...

The Maxim itself sells it at 1.8$/1K

Is this for a large scale product or a personal project?

 

[hardik.patel]

If i got success to reduce price...then ofcourse i go upto large scale..
Thats why i stick to reduce price.

I don't understand, either you are doing a hobby project or you are designing a commercial product, I'm still not clear which of the two is the case.
Are you saying that you are making a hobby project and if you manage to do it cheap enough you will go commercial?
