| This simple circuit is designed for use with all kinds of DC motors up to 40 amps. Basically it’s just a simple oscillator driving a bunch o...
| Cutting the power rapidly in the event of an overload implies monitoring the current through the load. This is usually done either by measur...
| This article describes a novel design for a high-voltage regulator that is very simple yet offers excellent performance. The output voltage...
| Curve tracers have been a staple in Elektor since 1979. This practical project from 2009 measures and records characteristic curves of NPN/P...
| The debate still goes on as to which are better, valves or transistors. We don't intend to get involved in that argument here. But if y...
| The MAX1562 is a purpose-built USB current limiter from the chip manufacturers Maxim. The device operates with a supply voltage from 4.0 to...
| As already mentioned in the previous parts of this article, this final amp needs more than just a heavy-duty symmetrical power supply. In th...
| If you ever thought of experimenting with pulse-width modulation, this circuit should get you started nicely. We’ve kept simplicity in mind...
| If you thought that an infra-red (IR) controller was only good for zapping TV channels then read on. This novel circuit uses a micro control...
