Step 14: Attach the cable

Peel back the jacket of the USB cable to expose 4-colored wires.

Attach these wires to the circuit board as follow:

Green - 2N3904 transistor ground
White - Junction of 0.1uF and 10K resistor
Red - SPST 5V relay switch
Black - Circuit ground

...or just look at the schematic again.

<p>This is so funny! Thumbs up. Next build: the force feedback underwear *G*</p>
Am I the only one who wonders what happens when the battery dies?
<p>hahaha That's an awesome anniversary present :D </p>
Can you use a ATMEGA328P-PU AVR chip instead ??
That's hallarious - and very&nbsp;inventive.<br> <br> I remember seeing something like this portrayed in some teen&nbsp;B-Movie made years ago.<br> <br> lol - things do have a way of making it from the&nbsp; screen to reality. Even a clap off bra!<br> <br> I&nbsp; Love this! - and can think of a new B-Movie and some not so &quot;B&quot;&nbsp;that the plot surrounds this little jewel.<br> <br> Now I think I'll&nbsp;take this idea and make the clap off Bikini!<br> <br> That should liven up the beaches here in Florida once again.<br> <br> thanx for posting this - it turned my day&nbsp;to the postive as I'll be smiling all day as i look at a woman and think of this invention of yours and adapting it to bikini's as i walk theboardwalk&nbsp;at the&nbsp;beach.<br> <br> ;0) definitly a favorite instuctable.<br> <br> again thanx<br> - chase -
<p>ProTip: bikini with disolvable stitches</p>
<p>Lol, amazing.</p>
<p>I'm not sure what to think about this, i can think of loads of instances where the clap off bra would be impractical, concerts, birthdays, watching TV and loads more where people are clapping a lot! </p>
<p>Hola amig@s de Instructables, gracias a este post en mi web modifique el proyecto para hacer una lampara que se activa con sonido, espero que les guste.</p><p>http://www.guillenxt.com/2014/01/lampara-de-aplausos-con-arduino-sensor.html</p><p>Gracias Clap-Off Bra</p>
Please show the full boobs
<p>Interesting concept. The gears in my brain are turning for other applications this could work with. How about a Pet Door that unlocks when the dog barks to go outside. Hmmm.. I assume it works with any sudden loud noise? <br>How strong is the magnetic draw? Would a rare earth magnet provide a stronger hold?<br>PS - Danica looks a lot like someone I dated many years ago. Ahhh, Memories ;-)</p>
Awesome. Just awesome.
<p>Quite. Quite Awesome.</p>
Heaven help the woman who wears this to a show or event where applause is customary!!
tee-hee- hee -lol! I &quot;applaud&quot;your comment
Thanks. I accept your applause. (looks around to see how many bras are falling off) <br>
I'd copnsider having a permanent magnet provide the clasp, and only have the electromagnet override it. Then it would rung longer, you'd have even less concerns with overheating, and it would default to &quot;stay-closed&quot; of the battery died, which may or may not be a plus...
That's exactly what he did.
I do not understand how I missed it. I just saw it walking meneame.net. Very original, clever and fun!
Ain't nobody got time for that!!!!
nice design......
Thats useful...
nice one........
Its sweet
Its extremely good :)
Thats interesting.
Its very good
Pretty simple..
nice !!
this is good....
Thats nice
For my ex-wife, this idea would have required explosive bolts!!!
CORRECTION: Arabs arent totally sexually repressed. they merely reserve all of it for their spouses. Both men and women arent allowed to be intimate with those they are not married to. Leads to a happier marriage without any jealousy etc.<br><br>putting that aside, hope i can give a suggestion. not that im good at electronics. actually the pulling of the pin using lateral forces is possible. it merely needs a machine that changes the direction of forces. i present to you the.... pulley!!!<br>string is horizontal, then it passes the pulley and change direction by 90 degrees. <br>Just add a bit more cloth below(or above) the hinges to cover the pulley and string. Also would need to take into account ways to put the contraption back together. So maybe dont cover the whole thing. hope it works because with a good gear ratio, you probably could pull it off with a very small DC motor which uses very little voltage. Thinking about durability, the need to washing etc, i guess maybe a bent tube would suffice. the string may get off the pulley tracks right?
this is awesome! but could it be washed? &gt;__&lt;
here are some ideas for clasps that wont use power to keep the bra closed using solenoids. if you make them out of plastic (or metal) you could get them down to about 2cm/ 3/4inch. The first you couldnt hide it behind a bow, but the second can be hidden, and easily reset, you just have to push the pin back in. :) dont have a workshop right now, or is mock something up
is that a guy<br>
I don't understand your circuit at all. There's no A5 on the circuit
I wanna see someone take it one step further and combine with the secret knock detector for a secret clap off bra.
Sorry boyfriend, you have to know the secret knock to see <strong>MY </strong><em>knockers</em>. Gol darn new technology. Sorry I could resist, I could, but I didn't want to<br>
Awesome! Though, like all early prototypes, this design could use a lot of refinement, particularly in the miniaturization department. The end goal being something a lady could comfortably wear for an extended amount of time (as pointed out in another comment.) Using lithium coin cell batteries and SMT components would be a start. I have to think that there must be a good reusable release mechanism that doesn't require as bulky of an electromagnet as well. Perhaps the 3 ring release mentioned below. <br><br>Maybe I'll get it a go :)
I have to say, I don't think this needs to be able to be worn for long term... Picture going to a meeting, and at the end everybody starts clapping.
No, you probably wouldn't wear it to the office. But maybe for a night out... <br><br>In any case it would be easy to add a arm/disarm switch. Or make it only activate on a knock code.
Hmm... I like the knock code
Clever, yes, but why no schematic or breadboard layout ?? chips are not free, and a misguided connect could blow it...<br><br>and when we download the arduino sketch, the filename is vastly different from the filename shown in your instructable... Has it been hacked or what?<br><br>thanks<br>
Terrific project. I loved that you included so much about the development process and some of the &quot;failures&quot; you had along the way. It's a great way to get people thinking about the alternatives.<br><br>I've got one: Since the attachment point should be under a fair amount of tension before release, consider the mechanism used to release malfunctioning parachutes in emergency conditions. It's called a &quot;3 Ring Release&quot; and uses lever action to reduce the force necessary to release the mechanism.<br><br>http://en.wikipedia.org/wiki/3-ring_release_system<br><br>It also has possibilities for the trigger on a trebuchet.
