ben1990 Posted August 23, 2009 Report Share Posted August 23, 2009 hey guys, a friend just bought a BMW, we just fitted 4 new speakers and an amplifier, but for fun he wants a circuit that will play a recording of the word Wilkommen (Welcome in German) through the system when the ignition is turned on.I guess i need to rig up some sort of circuit that will take a 12v positive trigger and have it trigger an MP3 player to play the file ONCE, but that will take too much time for the player to load and etc. so if anyone can suggest something that will take a 12v trigger and power supply, allow recording and playback of audio at line level and be able to do it within 3 seconds of receiving the trigger it would be very helpful, thanks.

www.electronworks.co.uk Posted August 24, 2009 Report Share Posted August 24, 2009 Have a look at ISD.com and their Chipcorder range. You can just record your own speech into it and play it back. You dont have to worry about triggering an MP3 player etc.Not sure what you amp looks like and whether you can feed a line in signal into it, so connecting this circuit up could be a challenge Quote Link to comment Share on other sites More sharing options...
ben1990 Posted August 27, 2009 Author Report Share Posted August 27, 2009 yeah the amp has low level inputs available, as we are using the hi level inputs from the factory head unit. We can just feed it in there Quote Link to comment Share on other sites More sharing options...
