It wouldn’t go. I messed about changing component values for while, then decided to actually try to understand the circuit. Now for an oscillator to work, we need an amplifier with a gain of greater than 1, and a phase shift of 360 degrees to get positive feedback. The circuit above is an amplifier, with

If you are mainly involved in designing or repairing digital devices, a logic analyzer is more useful than an oscilloscope for tracing signal through circuits. However, does this mean you should rush out and buy a logic analyzer? The instruments from the leading manufacturers are too expensive for home use or startup businesses, and the

Light propagating in a layer of scattering nanoparticles, shows the principles of diffusion – like tea particles in hot water. The deeper light is penetrating into the layer, the lower the energy density. Scientists of University of Twente’s Complex Photonics Group, however, manage to turn this falling diffusion curve into a rising one, by manipulating
