Time Switch Module 12V NE555 Monostable Switch Delayed

Blink any color you need! Use the Tri-Color LED board as a simple indicator, or by pressing the red, green and blue channels, you can create any color. Very bright output.
This is a common anode design: to turn on a channel, you simply need to ground one of the R / G / B pins to illuminate that channel.

Wired Bone Conductor Transducer - 8 Ohm 1 Watt
This amazing speaker does not have a movable cone like most From the speakers you've seen, instead, a small metal rod is wrapped with the voice coil.
When the current is driven through the coil, the magnetic field makes a piece of metal expands and contracts, if pressed against a flat surface or cavity makes it a speaker! Often these size transducers are pressed against the jaw or ear bone to turn the skull into a speaker socket.
The effect is a perfect quality sound that comes from your head and no one else can hear it. You can also press it against your elbow bone and stick a finger in your ear to listen to the audio transmitted through your arm!
