Privy-C-4
Smartphone public restroom privacy protection peripheral | |
Privy-C-4 is a smartphone peripheral that you can attach to the
inside of a public restroom doorknob so that anyone trying to
enter,
broken lock or no, will get 5mA.
I know this can work because I just went running with a pair of
broken earbuds. Zap.

[+] 5mA will do squat. I'm surprised/skeptical that you would even feel it. |
|

We were deeply disappointed with this, as the title suggested a
combination of conformable explosives and plumbing fixtures. |
|
| |
What a let-down to discover it's nothing more than a joy-buzzer for a
door, which is Baked and WKTE. |
|
| |
A tiny low-lethality Claymore-type device would get a bun - not this. |

Wrong. In fact, not even right. I know we're going to get into
the "it's not the voltage it's the current" argument here, but I'll
try to take it slowly. |
|
| |
The resistance of the human body (from, say, fingertip to
fingertip - which is basically the resistance of two layers of dry
skin) is around 100kOhms. Thus, to produce a current of 5mA
needs an applied voltage of V=IR = 0.005 x 100,000 = 500V. |
|
| |
I can assure you that 500V is quite a deterrent. I can also assure
you that the resulting 5mA passing through any important parts
of the human body can do quite a lot of harm. |
|
| |
smartphones don't generally generate 500V. |
|
| |
And therein lies the problem. |

Wait - I missed that part of the technology stack where you swipe the screen and whipped cream comes out of the side. Where can I get some? |
|
| |
At your local Dunkin' Phonuts, of course ... |
|
| |
You could use low voltage and 5MA. There wouldn't be much
of a shock, but I'd expect the doorknob would be quite
warm. |
|
| |
The idea seems doable – electric gag “joy buzzers”
disguised as cigarette lighters have been arount since the
1960s, at least. |

// I know this can work because I just went running with

I started getting irksome ear canal zaps a few months
after my company-provided cellphone was changed from
a Blackberry to an iPhone. I’m unsure what’s causing it,
and why the Apple corded earbuds do it, while the
Blackberry ones, which at a glance seem different only in
color, didn’t. At first, I though the tiny speakers were
shocking me, but later, noticed it happened inside in low
humidity when I wore fuzzy slippers, leading me to
believe it’s static electricity traveling over cords’
insulation. |

The ones with xenon flashes most certainly do |

No, it's a known side-effect of Apple Corp.'s Moron Intensifier Ray,
whith which they brain-rinse* iphoney users into paying extraordinary
sums of money for their inferior, bloated, overpriced crap. |
|
| |
*Iinitially they tried brain-washing, but quickly discovered that if an
apple user's brain is given a thorough wash, when it's subsequently
dried it just floats away on the breeze ... |
