.. available; one good choice is Audio Test set [ 2 ] from Darkwood Designs. This free software also incorporates a level meter which measures the input-voltage level applied to the mic/line input of the computer’s sound card (Fig. ...
K Suresh EDN When you develop the prototype of a circuit using capacitors or when you replace an old, defective capacitor with a new one, you often need to know the value of the capacitor you use or replace. At times, the values printed on the ...

.. from the form. The coil is tapped one half turn from the 9 volt supply side to make a connection for the antenna. A one meter long wire antenna is sufficient. The 0.04 to 6 pF capacitor is used to tune in stations. The tuner needs an ...
.. Arduino Uno that lets you measure inductance. This is a functionality that I found missing in just about any digital multi meter. Yes, there are specialized LCR meters that let you measure inductance but they typically won’t measure ...
.. to measure the power consumption of a device. In this project we are building one (Figure 1). Figure 1. DIY Digital AC Watt Meter. This is an AC Watt Meter which can measure the real power consumption of a device connected to the ...
.. a simple and cheap circuit that features easy adjustment and good accuracy. The output signal can go directly to a panel meter or a microcontroller, requiring no complex data manipulation such as log or antilog calculations. The MG-811 ...
.. and output was also required, so I could not use an integrator or other simple design. The circuit is used in a distance meter, which is why little and constant delay between input and output pulses is so important. Testing has ...
.. simple equations (R S is the series resistance, L and C the reactive elements and F R their resonance frequency): This Q-meter is unusual on more than one count: it is capable of displaying directly the value of the series resistance, and ...
.. Design Idea presents a very accurate, yet very inexpensive, capacitance meter. It was specifically designed for measurements of low value capacitance with an accuracy of better than 1 pF ...
