Picture of Musical Underwear
After the success of the Clap-Off bra i got thinking about where the world of gimmick undergarments could go next. There are so many options from led bras to velcro boxers, but i wanted to do something a bit more musical. I came up with these as the men's answer to the clap off bra (but of course this method could be done with women's as well).

Musical Underwear is the underwear that gets down when you get down!

Step 1: Supplies

There was some thought going hhw to make my underwear sing. Of course the arduino was considered as a first option, but i felt that it was a little over kill for this project. I found at radio shack a talking picture frame that was motion activated. It could also hold a message that was up to 10 seconds in length.

Also you'll need a pair of underwear, i chose some awesome looking ones from American Apparel.

And lastly you'll need a phototransistor that reacts to visible light a mini audio jack with free wires (not shown) and a 3 AA battery holder

Step 2: Picture Frame Circuit

My first step was to pull apart the picture frame and find out what i was dealing with. This is one of those "Push the button to record" picture frames, and it was triggered by motion.

Upon opening it up i discovered the "motion activation" was just a photoresistor, but it triggered the circuit when there was NO light, and i wanted the opposite. I had lots of ideas of building complicated transistor circuits to give a resistance when a phototransistor saw light. But i decided to try just to hook up the photo transistor as a direct replacement of the photoresistor and it worked! it reacted to the presence of light!

After figuring that out I removed the circuit from the plastic casing and desoldered the microphone, speaker, and photoresistor.

See the pictures for the taking apart process.

Amazing! now the challenge is (for someone else - I don't know how) to miniaturize it and make it less bulky. Hurry up and invent fabric-based batteries someone!

Awesome!!!!

Dude! These are awesome! I even love the color! ( Though, personally, I'd replace the bow with a flower blossom & add some lace! ) Great job!

Useful to indicate if you forget to zip your pants :)

I actually may do this.
Except replace the song with "Takin' care of buisness"
So awesome in public bathrooms...
Lol!
I vow to come up with something even more patently ridiculous...

Also props to Randy for the clapper bra... Now when any of us undoes a girls bra with one hand we can say it's a dying art and look all mystical to the tunes of our musical underwear...

Musical nickers, and a clap off bra... Instructables is great ;)

great idea but do you think you could record the sound on the video somewhere other than next to the building ventilation system or train station or whatever noisy place you were in?
lol, this is weird

You should make a night light using the Star Man power up from Mario Brothers.

When you walk by the night light it flashes / sparkles while playing that catchy power-up tune.

It should do the Hallelujah Chorus.
