help please, (child car circuit)

[chris m]

hello all,

I am new to this forum and im looking for help on my school electronics project.

I am making a small car for children to drive along in the road and it should have something interesting and new. So far i have designed a circuit with thyristors so if the child has a friend with one of these cars they can crash into each other and each time a LED will light up.

I need 3 new ideas (and circuit ideas if possible) asap

Thanks

Chris m

Well, I really dont get the first one...

but I had an idea in my mind along time ago, how about
an electric motor load controller...

The Idea is to control motors (eg. 8 motors in parallel)
then you can programme it to you desired loading conditions
and some motors will automatically shut if overload occurs
got it?

The H-Bridge motor driver with a geared DC motor should be suitable. You can use a switch to move forwars or reverse.
Used of suitable geared DC motor ensure safety since-as usual speed kills!
For the fun part install a mercury-switch activated alarm so when they crash to each other the alarm sounded.
