The ArduBat EarthLink
The basic working circuit on the ArduBat shield is a slight variation of the enhanced Simple Bat Detector, and is shown in the diagram above.Two LM386's amplify the bat calls from a piezo transducer and drive a CD4024 binary divider. The divide by 16 and divide by 32 outputs of the CD4024 are used to monitor and process the bat calls.Bat Detector Buyer's Guide Passive Detectors – Bat ...

PicoDetector : a PIC based simple and cheap metal detector. A short video clip is sometimes better than a long explanation : The idea of this circuit is to hack PIC oscillator circuit, by replacing the crystal by a coil : the frequency of the oscillator then depends on presence of metal near the coil, just like in a classic metal detector.. To detect changes of main oscillator frequency, we ...Detector definition and meaning | Collins English Dictionary
The circuit acts as a phase detector by comparing the frequency of an oscillator with an incoming signal and then feeding back the output to keep the oscillator in phase with the incoming frequency.LMH2110 8 GHz Logarithmic RMS Power Detector With 45 dB ...
