| 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...
| Many new devices require a headphone connection, but due to the high level of integration and miniaturisation there is usually little room l...
| We have designed a fairly compact adapter that lets you connect an MP3 player (or any other portable device) to the SCART socket of a TV. It...
| In most WCs with an extractor the fan is connected to the lighting circuit and is switched on and off either in sympathy with the light or w...
