| A few months while scrutinising a great design for a pulse-width modulated audio amplifier with a 2x100 W power rating and a very small encl...
| Some people find electric arcs scary, while others find them especially fascinating. If you’re not afraid of a few kilovolts and observe due...
| This design tip describes a simple equation to compose a desired resistance from two parallel connected resistors.The formula for parallel c...
| Despite the digital revolution there continue to be many photographers who still prefer to work with an ‘analogue’ SLR camera. While most of...
| The purpose of this circuit is not only to extend an optical digital audio connection (Toshiba Toslink) but also to function as a splitter,...
| Professional (directional) microphones often require a phantom supply of 48 V. This is fed via the signal lines to the microphone and has to...
| There is no doubt that this small power amp packs a punch. It is capable of delivering a healthy 200 W into 4 Ohm. Into 8 Ohm it can still o...
| This circuit shows a way to allow normal regulators to be used in situations with higher input voltages. Although the solution consists of a...
| Anyone who has designed circuits using the 555 timer chip will, at some time have wished that it could be programmed for longer timing perio...
