coin slot detector

by: amy khoshbin

when your coin slot is exposed, this wearable hip-pack vibrates that area to make you aware of it. you decide to cover up, or let it all hang out.

this hip pack is creating intelligence for an intimate space on your body to allow it to tell you when it's put into a public sphere. this not only gives you the decision to act on that, but it also raises awareness for a part of your body you're not using to thinking about and sensing with. for low-rise pants wearers worldwide, the coin slot detector adds another accessory to the trend.

coming soon: a joe-the-plumber-butt detector in rugged male design.
check amy's blog for updates: http://www.tinyscissors.com

tech summary: using a Lilypad Arduino, vibrating motor, and a photoresistor (measures the amount of light in your coin slot), you will make a wearable apparatus. when the photoresistor/your coin slot is covered, the hip-pack is at rest, when it/your coin slot is exposed, this triggers the vibrating motor to start vibrating & let the user know.

Step 1 Ingredients

get your ingredients together!

for this project you'll need:
-11.5 x 14.5 in fabric
-conductive thread
-lilypad arduino
-vibrating motor
-1N4004 diode
-photoresistor (sometimes called photo cell)
-1.5 to 5 V step-up battery pack
-wire
-wire cutters
-thread
-snaps
-snap tool
-suspender clips
-plastic tubing

for protoyping (not pictured):
-breadboard (you can buy this at Radio Shack)
-Arduino Diecimila
-USB cable
-alligator clips (also buy these at Radio Shack)
-USB to Serial Converter
-female headers
-headers

This is a totally funny project. I can not comment on the electronics as I am old schooled in electronics. Your photos are consistently excelent. I read about half the comments and others appreciate your efforts, as do I. If your not a Tech or EE, I would be surprised. Please give us more when you can! Thanks.

Southern saying..... Crack Kills

[techboy411]

COOL. so silly!!!LOL

[busterbuster18724]

we call it in nz builders crack

[nervouswreck]

Hi Amy, Over here in england we call it A Bricklayers Arse, Or when you spot one We ask politly "Can i park my bicycle"

[bmlbytes]

We call it a plumber's crack (Mid-Northern USA), probably for similar reasons.

[smogit]

Not sure what part of England you come from, but in my part we call it builders bum, so much more polite...

[uberdum05]

Yeah, sounds about right for yourkshire people.. :)

[Jay Spannerz]

It's called Plumber's Crack here in Australia too...
Just goes to show the world is being Americanised - in a good way, of course ;D

[pilgrimboz]

by speaking ENGLISH?? :)

[Nhuun]

We call it a plumber's crack (or just plumber) here in Iceland too ;D

[nervouswreck]

Hi Again guys & gal's, Just got in from work and watching a cooking competition, Theres a guy with 2 bicycle parking placesshowing above his jeans, The commentator said "I thought you said your a cook not a plumber"

[average joe 1999]

sometimes in america we say "crack attack!"

[MadCobbler]

Or we might say the moon is awfully bright tonight.

[ilpug]

or "say no to crack"

[ahuerta]

Even "crack kills" works.

[IncrediblyCondensedBlackMatter]

sneak right up behind his back,
and strike match
and drop the burning sulfur right between their cheeks!

[Jay Spannerz]

The Crack Is Back - Hehe xD

[oRelyTo]

:P I am confused.

[NaturalCrafter]

Ha ha! I had to laugh as my friend works on real coin slots. I did not realize what it was till I clicked for a closer look.

Buy (or in true instructabler spirit, make) a belt. Problem solved. That's right, it took me two seconds to outsmart your arduino photoresistor flux capacitor stuff.

[hintss]

genius! a belt with the arduino photoresistor flux capacitor stuff!

besides, who dosen't like overcomplicating things?

[wbothun]

Maybe a belt with the photoresister that will engage a belt-tightener

[Gamernotnerd]

You don't need the Arduino, just wire the photoresistor between the motor and the battery, cheap solution. Or use a MOSFET with a diode to block inductive kickback, if you can be arsed.

[Mr.NHRA]

 The photoresistor will take some of the voltage from the motor and will eventually burn out if you just hook it up in a line. The arduino is the most reliable way to go.

[uberdum05]

No, read the post above and that is the easiest and cheapest way, a arduino is OVERKILL for something as simple as that!

[markness]

I'd rather just stick with the quarter, but have fun being polite and all.

[NachoMahma]

. Fantastic job! Great iBle and terrific sense of humor.

[hintss]

whats your microQR code (atleast it dosen't seem to have the 4th square on it) say?

[NachoMahma]

. PS: so you don't have to download the pic and then upload it to the site, it says "NachoMahma" :)

Plumber crack detector. very nice. very nice.

[angelabchua]

hahahahha man, we need a video of this in action! I know I have been an offender once or twice, or 12 times.

[NostalgicStone]

 HaHAhahAha Kickass

[camscam]

I think these need to be government issued to all frequent offenders like an ankle bracelet or the device drunks have to blow in to start their car. As a side note I don't know how it ever became acceptable or hip to show off ays-crack!?!?! Its not cool put it back!

[camscam]

That's actually my point. We need a universal cultural ban on butt-cracks I think cute chicks have many better ways to get attention. God forbid if the "coin slot" becomes the new "muffin top"!?

[Derin]

(removed by the coin slot opener group for being against coin slots)

[titancore]

agreed!

[harrydask88]

niceeeeeeeeeeeeeeeeeeeee
