Hello /diy/

So I'm sure some of you are familiar with Hitchhikers Guide to the Galaxy. For my man cave I want my door to sigh when it opens and closes.

I can't find anything online to buy that does it, so I guess I'm going to have to make one. I don't expect to start with shit like this right away, build my way up to it with smaller projects.

I've messed a bit with electronics. I've built a Jacobs ladder and a tesla coil, replaced capacitors on computers, and so forth.

Anyway tl;dr

I wanna build a sighing door thing, but haven't really messed with things like this - where do I begin?

Arduino and many other microcontrollers can play WAV files because those are just a sequence of voltage levels you dump to a DAC. You'll probably want to connect an amplifier to that because a speaker driven directly will be quite. Have a switch trigger the sound to play when the door is opened. A reed switch or hall effect sensor will form a switch triggered by a magnet which is a popular way to implement door burglar alarms.

NEW RECORD MESSAGES TALKING PICTURE FRAME SILVER.

you just wire a switch across the 'play' button on the front. could be a self-adhesive magnetic switch, so you dont mar the door.

Waist way would be a limit switch. Door opens it trips, door closes it trips. From the switch you could go to any number of devices. Eg... that dudes talking picture frame.
