Voltage Characteristics Of Z-diodes
Wednesday, 16. July 2008

Z-Diodes are often used for simple voltage stabilized circuits. It is very important to use the Z-diode with the correct parameters.
This article shows an example for the voltage characteristics of two Z-diodes.


Observations On Batteries

This article takes a look on the costs of batteries compared to accumulators and additional chargers.


Impedance Converter And Non-inverting Amplifier
Sunday, 21. January 2007

This article shows an operational amplifier (OP) that is used as an impedance converter. This ciruit will then extended to a non-inverting amplifier.


Extremely Fast Case Construction

What hobbyist does not know the problem, that a commercial case does not quiet fit for the current project?

This method shows a case construction with a low bill of materials.
