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 ...

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 ...

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 ...

[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 ...

A high-resolution velocity profile sensor developed in Germany could improve the design of airplane turbines. Conventional laser Doppler anemometry systems measure an averaged velocity in a small ...

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 ...
