1. Concept development
One of my friends got mugged around lower east side area at the end of last year.
He got hit by baseball bat so his forehead got crushed.
Now he is normal and healthy but if that happened to me, i can't even imagine.
So l looked around the web how to be more safe on the streets of new york city.
The main purpose of clothe is to protect yourself. However, it is getting hard to protect yourself these days. So I came up with the concept of wearable that can protect urself. Apparently, pepper spray and stun guns are illegal in NYC and one of New York Times article said,
the form of self-defense, such as pepper spray etc, could incite attackers to further violence, said Lieut. Jack Kenney of the East Brunswick police. (http://query.nytimes.com/gst/fullpage.html?res=9C05EED7153FF934A35751C1A960958260)
I found 7 ways to protect from muugers. (Yes, some of them are funny.)
① Have whisle in ur mouth when you walk in the dark.
② Tell ur friends or family where you go and who you meet.
③ When you meet muggers, throw away your bags.
④ Throw away your belongings one by one when kidnapped.
⑤ Don't walk alone on the lonely back streets.
⑥ Rip off your clothes to get attention from other people when you face kidnapping or rape.
⑦ Don't follow your first date.
2. Requirement
1) Small enough to be carried in the body any time when necessary.
2) Do not hurt the attacker but scared them
3) Making space between attackers and defencer
4) Easily accessible and hidden somewhere
3. Ideas
The medium I could use is sound.
The least dangerous and the most effective way.
It can scatter attention and make mental and physical space to escape from that scene.
4. How
1 I found personal alarm at K mart that is small and loud enough.
The pin needs to be puled out to let alarm go off.
2) I took them apart and tried to figure out where to wear it.
3) Fabric and components integration.
Since most of parts are already soldered I needed to integrate battery part with fabric using conductive thread.
After integrating it, I sew the fabric to make the bracelet.
It was much cult than expected.
4) So here it is.
5) Thoughts
After I finished it, I played with it by squeezing it different ways and pulling the pin out different ways for a test. It finally got broken last night so that I had to solder wire connecting battery again. Now I can have little bit of sense that wearable is far more difficult than installation since people need to wear them. I read E-Broidery last night and I think I should've read it before I made it. It explains how to approach wearable fairly easily.
