Clap to remove this brassiere

Like some strange manga come to life, you can remove this brassiere with a clap of your hands. Under the red bow is a not-so-small mechanical clasp that replaces the original on the strapless front-clasping undergarment. We hate to criticize, but [Randofo] really went off the deep end of hardware overkill on this project. The clasp itself is the electromagnetic coil removed from the case of a mechanical relay. An ATmega168 listens for a spike in sound pressure from a microphone, then drives the relay to release the feminine support system.

It is Valentine’s day. The question being is this romantic or sleazy? Watch the NSFW video after the break and let us know your opinion in the comments.

  1. cool idea I guess.

    bra doesn’t fit, ‘model’ looks like a teenage boy, and now hackaday homepage makes me feel uncomfortable.

  2. If they only had invented that when I was in my early high school days – it would have saved me much embarrassment with the ladies. -> “Is it on the front?” no wait….I it got it! NO.. it got to be one of those “On The Back Snaps” NO Wait! … do I twist the damn thing? or …… Huh? .. Hey, where are you going? NO!… please .. come back! don’t go! I really DO know what I am doing, REALLY!

    … My failed youth!

  3. Man, you guys are titty-snobs. Yeah, she’s a little pasty and skinny, and most of you guys probably have her beat in cup size. But, as a self-proclaimed titty-connoisseur, I can attest that every boobie is a gift that is meant to be appreciated and enjoyed!

  4. If only all the women of the world had these. My hands would be red and sore from all the clapping!

    Awesome hack — I think we’re going to need a new section for “bra hacks” here at HaD. :)

  5. Oh yeah, I forgot about the hack!

    Fun idea, but the implementation seems a bit cumbersome. You’ve got magnets, a relay, a 9V battery, and even a nut and bolt. I guess if women are willing to wear heels and spanks and whatnot, then maybe it’s acceptable to some. Maybe you can sell a few to Lady Gaga.

    If I was to try to make this more awesome, more wearable, and of course more dangerous, I’d get rid of the bulky magnet/relay. Instead, how about a small firecracker with a model rocket igniter? A black cat with a little cardboard between it and the skin should be safe. Boobies and explosions… I think I have a new fetish.

  6. Anyone not comfortable with their own sexuality would feel uncomfortable looking at a man with a bra on! I wonder how many women would be comfortable at the theater with one of these on? Encore!

  7. I know how much practice and engineering goes into making things fall off correctly for burlesque performances. This is a nice piece of costume if it can stand up to some reasonably energetic dancing.

  8. Ouch! I don’t wanna say this, but I will.

    Haven’t you guys seen lady tits before? THAT is NOT a guy, that is a lady. Actually named Danica Uskert.

    Sooo… Many virgins here I recon :/

  9. @joegeek: I just simply watched a youtube video demonstrating how to … em … unhook a bra one handed. Haven’t had a problem doing that since – in fact, it’s remarkably easy once you’ve seen it done.

    Now, if you were doing this in the pre-youtube days, I can certainly understand. God I love the internet sometimes. Truly, this is what it was meant for! :-)

  10. Janet Jackson and Justin Timberlake could have saved themselves lots of problems if the designer just slipped this “malfunction” into her outfit… all those years ago.

  11. I slowly get why guys with a technology fetish are instantly suspected to be creeps or idiots. I wonder if the tit-critics have half as bold a mouth in reality…

    The idea of this hack had me laughing and I agree there’s a lot to be refined and sized down, but after all it is a prototype and it obviously works quite well. Having a finished version of this could be fun in many situations, pleasant or not :D

    Also, wtf? I just looked in mom’s drawer some dozen years ago when I needed to find out how bras work ;p

  12. Yes, gentlemen, that is what a woman looks like who is slender and has natural breasts. Think Taylor Rain… or add in the light skin and think Stoya. And don’t pretend you don’t know who they are.

  13. I made no implicit judgments in my statements. Male, female – doesn’t matter. Without the context of face or arms or anything else really and without looking at the movie, it is possible that one might assume the wearer to be male. Which, again, I made and make absolutely no judgment calls on.

  14. I also think that the fact that this bra is something like 4 cup sizes or more too big also contributes to the confusion issue.

  15. Now – I know as well as anybody that many projects need a lot of components. But… wow.

    Step 1.
    To open bra automatically, assemble the following:

    A front opening strapless under-wire bra
    Black fabric
    Small nut and bolt
    (x2) Prototype circuit boards
    An Arduino (w/ATMEGA168 DIP chip)
    28 pin socket
    (x2) 22pF capacitors
    (x2) 0.1uF capacitors
    10uF Capacitor
    16mhz crystal
    1K resistor
    10K resistor
    100K resistor
    2N3904 NPN transistor
    7805 voltage regulator
    5V SPST relay
    5V DPDT relay
    An electret microphone
    9V battery connector
    A spare USB cable
    1″ shrink tube
    Threadlocker
    A small grommet
    Elastic band
    Double stick tape
    Quick-setting epoxy
    Ribbons and frills
    Sewing stuff
    Soldering stuff
    Tools of various sorts

    Wow. I would have thought that a fifth or a few dollar bills would do the job just as well and much quicker too!

  16. What? No more song jokes?

    If yer happy and ya know it, clap yer hands! *clap clap*

    Personally, I’d love to see that at a strip joint. It’d be so tacky but so freaking awesome at the same time. I’d wave a couple bills for that.

  17. The trap comment made me laugh so hard, I wasn’t able to watch the video – which maybe was a good thing.

    I wanted to read the comments xD hahaha

  18. An Atmega 168, eh?

    Why not just have this thing cabled into a petaflop Beowulf cluster instead. Then it would be more of a hack by current standards, right?

  19. haha, at least im not the only one with misconceptions of the person in the photo. I was like, hey guys come look at this dude in a clap off bra! then boom, small tiny boobs emerged.

    I had to watch it again to be sure i saw what i saw. Even now that im at home im double checking.

    Not a bad hack. I’ve always used the pintch release move on bras. always worked for me. ;)
