Analog Devices has developed a new motion sensing device specifically for energy-constrained portable consumer products. – ADI’s ultra low power ADXL345 three-axis iMEMS digital accelerometer extends ...
Perpetual motion devices are either a gag, a scam, or as in the case of this particular toy that [Big Clive] bought on AliExpress, a rather fascinating demonstration of a contact-free inductive sensor ...
Setting up your smart home can mean a lot of different things. You could be choosing different devices, or you could be deciding how to use the smart home devices you just got. Just purchasing one ...
One type of friction can waste energy even when two perfectly smooth surfaces move against each other, but researchers are getting a handle on how to attenuate or stop it completely ...
