Connect this to that with a set-screw coupler. These couplers are made of machined aluminum and have a spiral cut that makes them slightly flexible so they can be fit to two shafts even if they are not perfectly co-linear and will help reduce binding effects. The way they're cut, they're a little springy in the X Y & Z linear axis but not in the...

This sound sensor uses the onboard electret microphone as well as the LM386 amplifier to detect any sound that is beyond the threshold setting. The level of the threshold can be set by the on-board potentiometer. This module will output a HIGH signal when the sound is lower than the threshold, as well as LOW when the sound is higher than the threshold.

EL Wire, also known as Electroluminescent wire is a stiff wire core coated with phosphor and then covered with a protective PVC sheath. When an AC signal is applied to it, it glows an aqua (blue green) color. You can make it look different colors by changing the coating, for example this is a bright white. It looks a little like thin neon. Very bendable,...
