Much like George Lucas and the original Star Wars films, many of us may find that our passion projects are never quite finished, especially when new technology comes around or we just want to make ...

[Trax] was asked by a friend to build a device that could detect the presence of a car in front of his garage gate for it to open automatically. After searching the web for such a project and trying ...

Many red lights fail to detect smaller vehicles like bikes and scooters due to sensor limitations. Inductive loops, common in traffic signals, rely on sufficient metal mass to register a vehicle.

If you are stuck at a stubborn traffic light, try these tips to help the sensor detect your vehicle. Then, you can continue ...

Waiting alone at a red light that simply refuses to turn green can feel like the universe is pranking you. Anyone who has driven late at night, or who rides a scooter or bike, knows that sinking ...

The detector comes in both single and dual-loop versions with separate outputs for each loop. Single-loop versions have two outputs, one pulse and the other presence. Outputs in the dual-loop system ...

Inductive sensors are non-contact proximity sensors that detect ferrous targets, ideally ones made of mild steel thicker than one millimeter. They consist of four major components: a ferrite core with ...

Download this article in PDF format. We’ve been waiting for a long time and now it’s being implemented widely—namely, artificial intelligence (AI). From automatic factories, self-driving cars and ...

It seems like engineering 101, but do you actually remember the specific differences between inductive proximity, inductive displacement, and eddy-current sensors? I asked a few friends and everyone ...

Twenty-one year old Ana Gamble sits on her black scooter at the intersection of Hull Road and Southwest Thirty Fourth Street waiting for the light to turn green. As she waits, the other traffic ...

A traffic signal sensor in Portland. Welcome to our newest column: Bike Science with Shawn Small One of the more frustrating aspects of cycling in an urban environment is not being able to trigger a ...
