Trigger traffic lights to change from red to green Length 1:23
Curated 10/31/07 Hosted by youtube.com
Creator's Site www.kipkay.com

This instructional video shows how change traffic lights from red to green, using science, and without actually having to know anything about magnetic fields or properties! Save gas, time, and frustration in your car and during your commute! Works great! See the test results! Yay for Kipkay! The trick in this video hacking tutorial will teach you how to get green lights on your bike or motorcycle that is too small or light to trigger the traffic light.

In Colorado we have a lot of the laser triggers at our intersections so this wouldn't work all the time. But using this along with the light sensor triggers you can buy for bikes is teh win! I'll have to come back to this video when I feel like doing the work =)

This is a gimmick. Magnets are simply not necessary. I can trigger traffic lights on my bicycle, no problem. The trick is to put your wheels directly on the center wire of the inductive loop. I've never had this fail. If I can do it with a bicycle, a scooter or motorcycle should have absolutely no problem.

JustYourLocalRocketScientist (3) 5/23/09 11:02 PM
lol the sensors are right at ground level, and radio signals are similar, a weak magnetic signal that is picked up from far away, but you still hear radio.

how this works is basically all the magnetic fields in the metal grains in a standard nonmagnetized car look similar to this line : /_||\_\////\|
not aligned at all. now, the inductive sensor in the road, detects a magnetic field from these nonaligned magnetic fields in a car, but they are weak, so you have to have a decent size hunk of metal.

what the neodymium is actually doing, is making a strong enough magnetic field that the different grains in the smaller metal bike are aligned like this: |||||||||||||||||||
They are all lined up!!! lol so essentially the stronger magnetic field is caused by the fact that the small metal bike has all its magnetic fielsd in each of the metals grains aligned, so none of the fields are canceling out other fields in the metal by pointing in another direction.

aka, you put magnets on a bike, and it has the same amount of magnetic force as a nonmagnetic car of a much larger size!!!

Or, at the very least that is the theory behind how this works. (even in a magnetized piece of metal some fields aren't lined up, and more fields line up if magnets are stronger, thus the need for neodymium, or some big ol' magnets :) )

Hopefully I explained that well enough for those who are interested in the theory of this to get it. (years of engineering have rendered me incapable of nontechnical communication :) )

this coming from a guy that thinks lasers embedded in a hairbrush will regrow hair. LOL. He really does too. It's one of his instructibles on metacafe., A quick google search on such rubbish though, shows it's scientifically proven to be total nonsense and quackery. Which makes me suspect this guy just does a lott of scouring of other peoples work, on tips tricks n things, and repackages them as his own. Basically makes a fortune by stealing and plagiarizing.

commuter 3/25/08 4:21 AM
The sensor wire is actually only 2-3" below the surface of the road, so it shouldn't be a problem. I also make a habit of riding directly over the saw cut and 80% of the time that's enough to trigger the signal. If it doesn't, call your local DOT office and report it that it needs to be repaired or have the sensitivity adjusted.

CloudchaserShaconage (2) 9/2/08 8:22 PM
I tried it on my scooter with about 7X the amount of neodymium magnets used in the video an' it didn't work, at least not at the light nearest my home. I sat there for two minuites waitin' for the light to change so I could make a left turn. It normrally only stays red for a minuite at the most when my car sets the same sensor off. Good thing that here in Tennessee, there's a state law that is a bike isn't settin' off a traffic sensor, the rider can run the light after a complete stop if the traffic's clear. Still too early to tell if it'll work at other sensors that my bike doesn't set off

If this DOES work, it needs to be REMOVED FROM THE NET RIGHT NOW. This poses a SERIOUS safety threat to all drivers. There are red lights for a reason. You could put all other lives around you at SERIOUS risk! What if you were responsible for 3 infant deaths? I'm not even going to get STARTED on the legal #$%@ too! This #$%@ needs to be OFF THE NET. True of otherwise, get rid of it! Putting an F!

tess_the_tyrant (2) 2/18/09 11:08 PM
lol you have no idea how these things work, do you? The sensor simply recognizes that a vehicle is waiting, and if no cars are driving the other way (or the other way has been green for a longer time), then that signal turns yellow, and then red. This doesn't IMMEDIATELY change the light to green whenever you roll up. There's formulas to make it fair.

usernameusername 6/10/09 12:21 AM
Oh yea, and I used to ride M/Cs for many years and if I ran into a light that would change I'd just get off and run over and push the cross walk button. Otherwise, if it was a turn I would make it when it was safe with no cross traffic, or just take a right and go down the street to where there's a working light or stop sign then make a U turn and go back to where I wanted to go.

retarded (-2) 1/25/09 1:33 PM
wow, this is just as retarded as it sounds. everybody hates sitting at traffic lights but it doesn't mean this retard idea will work. The magnet going to pick up so much crap from the road and it's going to weaken the magnet. beside that, you're going to have so much crap under your bike. therefore, that will make it unsafe. if it does works, what kind of a chance will you have by going against a car with your little mopped by changing the light? Good luck with this retarded idea ROTFLMAO!

kvibik (4) 1/28/09 7:06 AM
Most of the magnetic field will be concentrated on the lump of iron the magnet is attached to, so I don't think it's going to have a lot of force left to pick something up.

NoNameLin (2) 2/15/09 12:01 AM
The light isn't going to just suddenly turn green. This trick simply trigger the sensor to tell the lights that a vehicle is waiting. If you don't trigger the sensors, you might end up waiting forever.

gatordog3 (2) 2/17/09 12:24 PM
It's the same as if you were in a car! Motorcycles just don't weigh enough and you have to sit at intersections until another car comes behind you, because it doesn't know you are there. This is not a hack of any kind it just alerts the electrionics at the intersection that there is a vehicle there.

michaelmayo (2) 2/27/09 2:06 PM
use a series of strong electro-magnets, running under your car or bike, also use a device which can pulsate infra-red light to the traffic light sensor which is designed to detect the flashing lights of the emergency services, this way the system will auto overload and will give you priority over any other traffic........

if this fails then install a bluetooth device in the traffic light server box at the side of the road, if you have a mobile phone do a google search and update your phones driver using c++ or python, then you can auto-detect the traffic light set before you approach it and change it's configuration set at your speed in KPH or MPH, this hacking ability is intended to get you into learning how to crack technology designed to #$%@ your life !!!!!!

lvrk 3/18/09 1:14 PM
Michaelmayo, that the longest bunch of crap i have ever heard, you wasted more time coming up with that then you ever will at a light. Each loop is one wire wound up and then back to the control cabinet. They are only a couple inches in the roadway unless its be repaved. Flashing an infra-red will not set off the sensors for emergency vehicles and those sensors are only at key intersections. And they will not "auto overload" . Wow could throw out some more lingo to try and convince everyone. And there are nooo loops for pedestrians. Oh and the controllers in the traffic signal cabinets are no bluetooth ready idiot there is no usp port and you cant just walk up and flip them open, what a bunch of crap

I once thought it would be cool to create a device that would delay changing the lights the opposite direction if there was a car in the intersection. Turns out those jerks that give you tickets automatically when you run a light own the patent on that. So they rather give tickets then save lives, since most accidents occur when people run lights.
