Phones morph into 'stun guns' and 'tricorders'

[Jazzy]

Add-ons that turn smartphones into Star Trek-like tricorder medical diagnostic kits, Predator-style thermal vision cameras and even electric "stun guns" are being promoted at the Consumer Electronics Show.

The inventions join a growing list of hardware that adds abilities to existing handsets.

Most will go on sale this year.

Would you use any of these add-ons? If so, which one/ones?

Hook me up with a stun gun mobile!

 

[Evil Eye]

Nah, I'll keep my money, thanks.
Not to mention my battery life.

If I had a stun gun, I'd probably accidentally shoot myself with it!
