Arrow Green Light Trigger

There is a recently developed active green light trigger for motorcycles.

The device detects a signal from the sensor loop and transmits specially generated signal back to the sensor making it "think" that a large vehicle is passing above. It powered by 12V, includes loop antenna, and optional LED. Works with all induction loop sensors.

Sold on eBay:

Hit the starter, does the same thing.

Oh, and great spam post.

Arrow How It Works

The active Green Light Trigger device is designed for U.S. Department of Transportation published specification.
It measures a sensor signal and generates "a correction" for the original signal. DSP based device has enough accuracy and power to trigger the sensor. The device detects and activates traffic sensor while standing within a loop or up-to a foot outside the loop sensor.

After I have finished the development and installed the device on the motorcycle, my driving habits were changed. I stopped to "recalculate" a route to avoid some problem intersections; just ride where I wish. It does not matter when and where I ride, I always get green light!

Hook us up with a freebie to test this theory out.

Is it bad for the starter to press it when bike is already on? There is so many lights here, I would wear it out. :p

Sorry, no free samples!


I continue working on the device improvement. There are two device versions. Both are using the same algorithms and mathematical calculations; they are pin compatible. The devices will be loaded with latest firmware prior to shipping.

The first version is on sale now.
Motorcycle Green Light Trigger | Traffic Light Activator | Red Light Changer | eBay

The second version is sold at regular price. Main improvements are in PCB layout. This lot is sold with some add-ons for easy installation.

The others sell magic magnets at similar price, which has no scientific reason to influence the sensors.

The device has been carefully tested. But errors / bugs may exists in every product.
If any problem raised I will refund or replace the device.

Well but first, I am the Inventor of the device, not a spammer.
At the current stage I cannot afford being a sponsor, please understand.

So far there is no other existing device that makes motorcycles 100% visible to traffic light and garage gate inductive sensors. I enjoy it on my daily (mostly nightly) commute, and hope it may be usable for many other riders.

Magnets and ferrous material should not trigger the sensors. I have linked a document describing how the sensors work (pretty detailed but long).

In few words: the inductive loop sensor feels either conductive or magnetic material. A large conductive object decrease loop inductance, a magnetic object increase it. The sensors made to register a decreased inductance - they detect large conductive body like car floor, but not a steel axis.

And I made a real device based on this theory. The device calculates a desired (for every specific sensor) correction and transmits it back.

I am a bit curious for a video also!

I currently have a couple rare earth magnets under the bike but never know if it worked or not cuz I usually scoot up a bit and have the car behind trigger the sensor. Don't really come across much lights at all so don't know if magnets work for sure but if your theory is right... Let's see it in action!!!!

Are we there yet?!

Green Light Trigger in Action

Here the today's video clips. I do not have a helmet camera, so camera girl presents:



Notes:
Alarm red LED (key sign) used for Green Light Trigger status.
The installed Green Light Activator device is the second version (first version has different blinking pattern):

I'm interested to learn more about how your device detects what range the inductive loop in the pavement is looking for and how it transmits the signal back.

It would also be nice to see a video showing the behaviour of the traffic lights with and without the device installed so a difference in time can be measured. This would be good marketing (i.e., convincing) material as I think there would be decent demand for this product if people knew it existed.

I detect induction loop in full frequency range of 10 to 200 kHz, and with accuracy 0.001%. As for transmitter element used H-bridge powered by 12V.

If you are interesting in-depth, I would refer to few published patents (not mine):
https://www.google.com/patents/US7432827
https://www.google.com/patents/US9123238

The described in the mentioned patents solutions have complicated electronics, and no commercially available product exists.

My device implements most logic in software and DSP, use cheap electronics, and do not infringe other patents.

Firmware update

There was a minor bug in calculation of very weak signals. The device usage had not been affected by this bug.
Never the less, I fixed the bug in firmware and have updated the version (2.03) in eBay listing.

Firmware update

I have propagated bug fix to the "first project version" device. Now, I can confirm that both devices perform the same in terms of sensitivity and accuracy.

Firmware version 1.05 has been updated for the listed devices:

Glad to see you are supporting it. I will probably buy one when I get a new bike. I'm converting the RR to track and hoping to pick up a FZ-07 this season.

[edit] Come to think of it, how would this look on a naked bike?
