A Collection of Electronic Projects and Circuits

If you’ve already formed through a few projects from Electronics Projects For Dummies and bent the electronics bug you ability appetite to try a few projects from added sources. To advice you out here’s a account of some absorbing projects that I’ve begin about the Web. These projects attending absorbing and are able-bodied accurate but we haven’t had a adventitious to body them all, so after-effects may vary! Some of these projects use aerial voltages and currents we accomplish no assurance as to their safety, it is your own albatross to alone accouterment projects that you accept the ability and abilities to assignment on safely.

Controlled Mass Production of Nanowires

Controlled Mass Production of Nanowires
Reliable manufacturing of nanowires for large-scale, integrated devices (lab-on-a-chip, for example) requires that these structures can be grown at desired locations over a large area. Kris Bertness and colleagues at the National Institute of Standards and Technology (NIST) have grown Gallium Nitride nanowires on silicon substrates at controlled locations with essentially perfect selectivity.

Blue-green diode lasers New Evolution

Blue-green diode lasers New Evolution
High power edge emitting diode lasers are the most efficient coherent light sources available. They feature small physical size combined with high reliability. Semiconductor lasers can be manufactured from the ultraviolet to the mid infrared. However, especially in the visible spectrum from the aquamarine (480 nm) to the red (630 nm) including green, yellow and orange no emission from diode lasers is available – a wavelength range needed by a vast number of applications like medical treatment and diagnostics, spectroscopy, data storage, and display technology. One way to obtain coherent light at wavelengths where direct laser emission is unavailable is frequency conversion, like second harmonic generation (SHG).
