Buda Posted January 11, 2003 Share Posted January 11, 2003 I read a while ago that there was a chip you could programme wih a sound file, can anyone programme a chip with a specific sound and do the electronics bit with a speaker so that it is activated by the inigtion - fuel pump - once - when you turn the car on prior to pressing the red button and going brum brum?

Julian Thompson Posted January 11, 2003 Share Posted January 11, 2003 Yes, but remember that the output at chip level is tiny and you'd then need to amplify the signal to a higher power to enable you to power a speaker. This is still only a small circuit (depending on what you want). Link to comment Share on other sites More sharing options...
