Laser projector



Instructables user echo_anomie posted a nifty howto for creating a very simple portable laser projector. With a bright enough laser, you can project an image across long outdoor distances and there’s never any need to adjust focus.

When it’s all assembled, you just drop photo slides in the path of the beam and they are projected wherever you have the thing aimed. It’d be interesting to try this with some kind of LCD in place of the slide. This should let you project eerie green videos on skyscrapers around town.

    All 3 of my bluetooth headsets will only pair when it is put in a special “pair mode” (typically by holding the power button for 10 seconds or more).

    I’d be interested if this attack will work on devices with this “feature”.

    umm, I call BS for a few reasons.

    1) The pin is used to associate two devices (the handshake) not for ongoing communication.
    2) Once the headset has been associated to the device, it cannot be re-associated to another device while the first device is still active. So I would have to turn my phone off.
    3) Even though you may be able to send a signal with that super nifty antenna, you most likely will not be able to receive the signal back unless they have a similar antenna.

    You’re more at risk with the FBI being able to remotely activate your mic.
