Create a circuit with bright red LEDs that would attached
to the front and back of a motorcycle helmet that would
flash for x period of time when the operator moved their
head left to right, like saying NO, NO to a car about
ready to pull out in front on you....
Thanks! |

Wiggle your ears ?:-)
It'd be sensitive to unintended motion.

I think I see what you want, but activating it with head movement on a
motorcycle would be unreliable.
If you ride you know that motorcyclist get bounced around a lot. I'll think
about it some more.
BTW: I removed your crossposts, way too many.

Use a small electric motor and flywheel mounted parallel to the ground.
Sharp movement left or right will create a small DC voltage to be
rectified (full wave) and used as your trigger. You will have to adjust
sensitivity to ignore turns.

Analog Devices motion sensors connected to an RPG. Easier to connect a
switch on your handlebars to the RPG launcher. If you aren't protected
against shrapnel, perhaps a photoflash unit to blind them into
submission. |

Why don't you hook up a high-powered PA system, put a microphone in your
helmet, and just yell out "NO, NO!"
You're welcome, in advance.

Red is a wrong choice - a color harder to detect. Automobiles
designed by engineers (not by fashion designers) use orange (amber)
rear turn signals. Orange cuts through fog, smoke, rain, etc; and is
easier to see at dawn and dusk.
Sources of motion sensors include those $1 electronic pedometers or
game handles from Wii video games. |

Those electric powered "gatling guns" do perfectly adequate damage to a car
without the blowback of shrapnel that a HE missile produces. |

And they look real cool spinning around even when they run out of ammo!

I'd like a C02 IR laser to wipe out the nose picker's tires.

If you have a good low beam halogen headlamp - by good I mean no or
low glare - it is virtually invisible during daylight. The damn
things are like movie projectors - well collimated beam with no
overshoot. I put a little 10 watt halogen about 2" below the main
beam and it is more visible because it isn't collimated.
I also 48 white 1300 mcd leds in a rectangular pattern below my
headlight - the drivers seem to pause longer trying to figure out what
it is and that seems to be keeping them from scaring me.
It is also a useful light for driving at night - the 10 degree beam
spread isn't annoying the oncoming traffic and makes a big difference
lighting the road 10-20 feet in front of the bike.
A trigger able xenon flash inside the headlight would probably work
too.
Headlight modulators are OK but not really noticeable enough in my
opinion.

I would use a gyro, coupled with a microcontroller. The microcontroller
would need to interpret the waggling of the head, using some clever
software, without getting confused. You might be able to do this with analog
circuitry, but it would be much harder to get it to work.
One problem with this is getting the power. Do you want batteries in your
helmet? Will you plug it into the bike?

Bob Monsen |

But I've found that the recoil really slows me down.
