1-07-2009 | When the position of a servo can be controlled via a voltage, it can be implemented via a potentiometer acting as a voltage divider. However...

1-07-2009 | With a bit of adeptness, you can build an electronic scales based on a servo motor. Depending on the type of servo you use, it can measure w...

1-04-2009 | Through the use of directives found in the integrated assembler (version 2) of AVR Studio we can create instructions using macros that make...

1-03-2009 | To be able to play an electric guitar you need, in addition to the guitar itself, a guitar amplifier. The guitar then needs to be connected...

1-10-2008 | The instrument described in this article combines the functions of a sweep frequency generator (‘wobbulator’) and a spectrum analyser. In th...

1-09-2008 | We've already covered a laser projector in an earlier instalment of this series. This time however, we use a different projection mechan...

1-07-2008 | This circuit lets you control a servo in a simple way. It is built around a cheap and common logic IC. Together with a few resistors, capaci...

1-03-2008 | A voice changer that emulates a so-called Cylon voice can be implemented with the help of a small microcontroller. Those of you who have wat...

1-03-2008 | A PLL (phase locked loop) can also be used as a frequency multiplier. The multiplication factor is then determined by the divisor in the fee...

1-11-2007 | For the design of large electronic circuits you don't just need the necessary knowledge and experience. You also need good preparation a...
