Guest Roiyuda Posted January 2, 2014 Report Share Posted January 2, 2014 Hello everybody!I'm trying to build a drawer that makes a sound when opened. Being new to this world of electronics, I have no clue how to do this...This is a regular kitchen drawer. I want the whole mechanism to sit inside it. I need it to include a small speaker that will be automatically activated when the drawer is opened, and play a specific sound (a 5 seconds tune).I thought I can use a simple cheap speaker such as http://dx.com/p/portable-mini-usb-music-speaker-w-tf-card-slot-mp3-black-silver-245498 , and this way I can put the tune in a CF memory card.However, I have no idea how to power up permanently (DC) this sort of speaker, nor how to design it so it'll be played once you open the drawer. I'll appreciate any idea and response :-) Quote Link to comment Share on other sites More sharing options...
