A 3D printing enthusiast has made a cute, functional lo-fi digital camera using an optical sensor salvaged from a discarded ...

In this tutorial, I will show how you can handle the optical sensor inside a cheap optical-mouse for your next microcontroller project. Hope, this will allow your preferred microcontroller to look at ...

I am always on the lookout for ideas for simple test and measurement instruments that can be used on my workbench. Over the years, I have built dozens of little test instruments and home lab ...

The same inexpensive, but high-quality optical sensors employed in the common computer mouse can enable small mobile phones and digital music players to be used as their own pointing and gestural ...

Every time we watch Minority Report we want to make wild hand gestures at our computer — most of them polite. [Rootsaid] wanted to do the same and discovered that the PAJ7620 is an easy way to read ...

Researchers have been able to confine light down to a space one atom, the smallest possible. This will pave the way to ultra-small optical switches, detectors and sensors. Light can function as an ...
