    Electronic Eavesdropping Devices Detector

    yourwinns, The BFR90 can be replaced with BFG90, BFQ28, BFR14, BFR49. The MC3403 with LM324 And the NTE112 is a TV UHF Mixer diode can be replaced with BA481 Ante ::)

    Bob, I have replaced your R2 with two resistors. The op-amp will (I hope) put out approx 3Volts when 6 A is passing through the

    Question on the Plants Watering Watcher circuit

    Audioguru, As surveillance for a plant (dumb or not) it sounds like very good circuit. I have to agree on your thoughts about the form of message the first circuit gave. Your suggestion will of curse give a much clearer message. Even JLB:s application measuring salt concentration can perhaps...

    isolated motor feedback circuit

    Bob, What is the highest value possible for R2? This will determine if the opto LED can be driven right off the voltagedrop or else you need an op-amp to boost the voltage. Ante ::)

    BINARY TO BCD decoder

    Hi Guys, Here are some nice projects on this site, among others something for the LM35. http://www.x-robotics.com/sensores.htm#LM35 I hope it will generate some ideas! Ante ::)

    detector prototype

    This circuit will detect mains power and indicate this by the LED blinking at about 3 Hz for 50 Hz mains. The antenna is anything from 5 to 25 cm of wire depending on the sensitivity that is needed. Ante ::)

    isolated motor feedback circuit

    Bob, I guess we where writing simultaneously as I saw you message after I was finished with mine. Is it only motion you want to detect? In that case an opto sensor will come in handy, giving an output while the shaft moves and non when it stops. Ante ::)

    Question on the Plants Watering Watcher circuit

    From the original circuit remain one resistor, one potentiometer two caps and a LED. I would call that a change. Where is the finished circuit then? I sure there are some readers that are a bit confused not getting to see the hole picture (drawing). Ante ::)
