Looking to build a Stopwatch

[PeacepPipe]

Looking to build a stopwatch with a Crystal display,Like The brand accusplit
Which has 1/2 Inch or 1" Numbers.Counts up to 60:00:00 and can count the 1/100
But this time,Instead of the crystal display Be BLACK colored can It be
done,where the Numbers are Colored ETC:BLUE

The old stopwatchs back in the 70's,early 80's had red numbers like the Old
calcualtors and watchs.why was that?

Please help Thank you

you can get different colored LCD's but the reason the old ones had
big red numbers is because they didn't use LCD but actually 7-Segment
LCD's all tied together.

There's lots of ways you can build a stop watch, the two that come to
mind are: 1) logic 2)micro

you can use software like maxplus II to design the logic circuitry
nesscesary for a stopwatch, its not too hard I did it about 6months
ago for my intro to logic class.

or you can use a microprocessor like the pic or rabbit to code a
stopwatch that would run with a colored LCD (or LED's for that matter)

hope this might give you some ideas,

Cheers,

In those days most red dislays were LED's rather than LCD I thought ??
