Simple Schematic Collection

555 Timer Circuit Diagram Police Siren. This 555 timer police siren schematic diagram use 2 555 timer to produce an up-down wailing sound. The first 555 is wired as a low-frequency oscillator to control the VOLTAGE CONTROL pin 5 of the second 555. The voltage shift on pin 5 causes the frequency of the second oscillator to rise and fall.

Laser Diode Driver Circuit Diagram

17/11/2017· Laser Diode Driver Circuit. A Laser Diode driver circuit is a circuit which is used to limit the current and then supplies to the Laser Diode, so it can work properly. If we directly connect it to the supply, due to more current it will damage. If current is low then it will not operate, because of not having sufficient power to start.

Properties and Applications of Gold

Properties. 1. Surface Plasmon Resonance (SPR) When gold nanoparticles are exposed to a specific wavelength of light, the oscillating electromagnetic field of the light induces a collective coherent oscillation of the free electrons, which causes a charge separation with respect to the ionic lattice, forming a dipole oscillation along the direction of the electric field of the light.
