7400 competition entry: Police lights and siren for a toy car

Posted on Thursday, October 20th, 2011 in 7400 contest by DP

Nathan entered his Police lights and siren for toy car into the Open 7400 Logic Competition:

A Little Tikes Patrol Police Car was retrofitted with a battery-powered emergency police lights and siren system as an entry to the Dangerous Prototypes Open 7400 Logic Competition. The circuit design focuses on simplicity and efficiency of part utilization by using only two 7400 series integrated circuits.

Check out the video of this project below.
