This is the beginings of a speed trap. Another club member a year or so ago told me that this project would go no where and be forgotten about. Well here is the read out that makes up the speed display

This is the circuit board that sends the information in binary and transfers it to numeric's. With this project I have had a crash course in CMOS and TTL/ TTL/LS and learned about other circuit nuances too. I do have to admit that my father (a master in circuits by my standard) has been coaching me though this project.

It Works!!!! I am thinking of only making the display two digits. The X through a segment means the segment has burnt out....
