Quiz Buzzers

Hi I'm very new to this so here goes. I help run some quizzies every now and then and thought it would be a good idea to make some buzzers that work on a fastest finger first basis like thay use on the TV. Making the boxes is no problem but i have no idea on the electronics involved. My concept is each team would have a box in front of them with a big red button on top. when this was pressed a buzzer would go off and a light would light up but it would stop anyone else from sounding their buzzer or light. i would need up to 8 modules to be connected at any one time. if anyone can help me with this bearing in mind my lake of knowledge it would be appriciated

Do a search for "Jeopardy". This question comes up quite often, and there are a number of circuits online.

IIRC, Elektor and Silicon Chip (Au) have done this.
