.. 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 ...
.. most realize. Take, for example, the smart grid with smart meters. Every day utilities are installing a shiny new smart meter on our house and encouraging us to take control of our energy future. We are to monitor and report consumption ...
.. Experiments were performed with a single solar cell of diameter D=7.5 cm positioned horizontally on a desk located 1 meter from a window. Although it was sunny outside, practically no direct sunlight passed through the window. Under ...
.. when using the SPIRIT1 with a range extender under EN 300 220-1 (v2.3.1, 2012-02) in the 169.400 - 169.475 MHz band, meter reading, tracking and tracing applications. The maximum allowed output power in this sub-band is +27 dBm (500 ...
