In this experiment we are going to work with a sensor which is a resistor that depends on light. In a dark environment, the resistor will have a very high resistance. As photons (light) land on the ...

The humble piezo element is often used as little more than a buzzer in many projects. However, you can do more with them, as [Something Physical] demonstrates with their nifty piezo noise box. Check ...

Deep freezers are a great thing to have, especially when the world gets apocalyptic. Of course, freezers are only good when they’re operating properly. And since they’re usually chillin’ out of sight ...

I'm building some speakers today(yay!) and I don't know enough about electronics to figure this out. I'm using three-way crossovers, and it has big resistors on it. Do I still need some for the piezo ...

Murphy’s Law predicts that it takes the first 99% of your time budget to finish the first 99% of a job and the second 99% to get it completed. The history of piezoelectric motors can serve as a good ...
