| Apart from chucking it in the bin, what can you do with old AM car radio or clock radio in your junkbox? How about turning it into a crystal...
| This circuit is purposely presented with many loose ends (not literally, of course) to stimulate experimenting with RF circuitry at a small...
| This converter is specifically intended to upgrade somewhat dated, digital signal sources. It recognises all common sampling rates and conve...
| Although MIDI (Musical Instrument Digital Interface) was originally developed for controlling musical instruments, it can also be used for n...
| The circuit diagram shows two LT1398’s from Linear Technology used to create buffered colour-difference signals from RGB (red-green-blue) in...
| In measurement and control systems a common method of sending control or measurement data over long distances is by means of a ‘current loop...
| An interesting DC/DC converter IC is available from Linear Technology. The LT1615 step-up switching voltage regulator can generate an output...
| Switch-mode power supplies are used in electronic circuits to increase (step up) or reduce (step down) voltage levels in the most efficient...
| A symmetrical ±5 V power supply is often needed for small, battery-operated operational amplifier projects and analogue circuits. An IC that...
