I want this circuit-the e-stethoscope too much, since this can help me monitor bearing defects on the machines I am maintaining.
May I know also who can give or design me a simple ULTRASONIC LEVEL DETECTOR FOR DISESL FUEL TANK of 2-3 meters high, using available electronic parts here in my country-Philippines.
The two big electronic stores here in my country are ALEXAN COMMERCIAL and DEECO ELECTRONICS, selling educational electronics parts, and kindly post also the equivalent part number/s of I.C.'s or Transistor/s, sensor/s.
More power to your site. |

A heartbeat is a very low frequency of about 16Hz. A cell phone cuts off frequencies below 300Hz and heartbeats would not be heard, maybe just clicking sounds. |

Thank you for your quick reply. Iam looking for an electronic stethoscope which should record the sound to a mobile phone. So my question is how can we connect the stethoscope to the headset jack. |

I fixed the simple Electronic Stethoscope project that is on this site and it works pretty well:
