Measuring speed with Arduino isn‘t something new, but the interesting part of this project that speed information is displayed on Flash application. Application has been built using Flex 4 and is ...

We know that measuring the speed of light with an Arduino is possible. It’s just that the implementation is hard. [Udo] hit upon the idea of pulsing a laser pointer and measuring the time of the ...

In this fun project an ultrasonic distance sensor is used to detect a “target” (i.e., a person, a cat, a burglar, etc.). The Arduino illuminates (blasts) the target using an inexpensive laser diode ...

This Idea for Design points the way for a new design approach in laser power measurement using piezo-resistance on MEMS membranes. Suitably designed, such sensors can handle a wide range of laser ...

Ophir Photonics Group, global leader in precision laser measurement equipment and a Newport Corporation company, today announced four new thermal laser sensors designed for measuring high pulse ...

[Mike] lives in a temperate rainforest in Alaska (we figured from his website’s name) and uses a 570 gallon oil tank to supply his furnace. Until now, he had no way of knowing how much oil was left in ...
