The Signal Sorcerer traffic light changer. Nothing to do with those MIRT type changers, now so discredited and outlawed. This puppy messes with the ‘inductive loop’ type traffic lights, you know, the strip in the ground. Does it work? Your guess, dear Earth born, is as good… And don’t forget to check out the SS1 model for bicycles. From $19.95.
Inductive loops detect iron (ferrite [Fe]) not aluminum, rubber, plastic, weight, mass, titanium, etc. Motorcycles, particularly the newer models, rarely have enough iron close enough to the ground to cause the inductive loop to detect their presence at the intersection – ergo, the light does not change. Signal Sorcerer generates a very powerful field that substantially increases the inductance in these loops, therefore causing the traffic signal to detect the vehicle it’s attached to and initiate a cycle change. Inductive loop technology has been employed in this capacity since the early 1960’s.
Don’t waste your money. I’ve got one of these on my motorcycle. I believe this could work, but the impulse is much too short to trigger the system. This spring I’m going to try pulsing an electromagnet with a 555 circuit at about 60~100Hz as I cross the loop.
