1-03-2001 | This pulse generator, which can be programmed using Visual Basic 5.0, employs the simplest imaginable hardware but offers capabilities that...

1-02-2001 | Not all AM receivers are created equal. The receiver described here is definitely not a run-of-the-mill type. The tuning range is not limite...

1-01-2001 | Although this supply was primarily designed for use with the Valved RIAA Preamplifier, we found that the inverter stage is useful in many ot...

1-01-2001 | Although MIDI (Musical Instrument Digital Interface) was originally developed for controlling musical instruments, it can also be used for n...

1-01-2001 | Pulse width modulation (PWM) is a fundamental technique in electronics. It comes as no surprise, therefore, that there are many applications...

1-12-2000 | With just a low cost DC adapter and the circuit described here it is possible to build a low cost stabilised, uninterruptible 9 V supply. On...

1-07-2000 | Nowadays, it is no longer necessary to use discrete components to build oscillators. Instead, many manufacturers provide ready-made voltage-...

1-07-2000 | Any stepper motor can be used as a generator. In contrast to other generators, a stepper motor produces a large induced voltage even at low...

1-07-2000 | Many circuits can be powered directly from the mains with the aid of a series capacitor (C1). The disadvantage of this approach is that usua...

1-04-2000 | It’s often the small, everyday things that turn out to have interesting features when you examine them more closely. In any case, here you c...
