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!

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.

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.

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.

Crossposted deleted.

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

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.

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

Sorry, have quite a bit of backing, read $$$, for this project and
was hoping to have some answers that would not be high
school quality, well I will keep looking for a electronics guy that
can do a project like this.

Gimmicks like this have a nasty habit of becoming compulsory adding to the
riders costs.

The better solution has always been rider education - to look where they're
going because car drivers can't be arsed!

why don't you just mount a button above or below the horn and wire it? It
would be a LOT simpler to implement. Actually you could make it activate
all the lights on the bike PLUS your helmet in a freaky light show. Maybe
the horn too.

Well, you asked, "How would you..."

What I'd do is put a steady red LED on the back, and a steady
amber or yellow LED on the front, and just shake my head when
I wanted to draw attention - the movement will attract the eye
of the viewer.

But there's a caveat - if you're thinking of using it like a
turn signel, it will be backwards - i.e., when you're looking
to the right, the LED will be on the left, viewed from the back.

So maybe it's not that great an idea after all. Sigh. I've been
thinking about how to mount some LEDs on my bicycle, but I
wouldn't want them to blink or flash - that's too much like
"emergency". =:-O

Have Fun!
