Raspberry Pi owners looking to use higher voltages with their mini PC, might be interested in this new opto-isolator board called the Opto-pi which has been specifically designed to be used with the ...

Plugging right in to that eerie “they’re watching me” feeling you’re supposed to get from normal portrait paintings, Opto-Isolator is an artwork that takes the sensation into the scary, robotic 21st ...

We’ve all raised a clench fist in anger over lost data, and it’s usually the result of unjustified optimism and lack of planning. [George] shared his solution that prepares for the worst: a circuit ...

The optocoupler board project is intended for general purpose applications where the signals are allowed to pass between two circuits without having to connect them electrically. The optocoupler board ...

When you buy an off-the-shelf automatic cat feeder, you might well expect it to do the one thing it’s supposed to do. Feed the cat. Well, at least as long as you do your part by keeping it filled with ...

This simple circuit provides better than 1% accuracy in optically coupling a DC voltage signal. To compensate for the non-linearity of the optical isolator, an identical device is connected in the ...

Reportedly able to survive in dust-contaminated environments, the OPI1270, OPI1280 and OPI1290 optical isolators consist of a red LED with phototransistor or a Photologic sensor. Target applications ...
