Download Circuit diagram and Programming: Download Libraries How to make 8 Channel 434mhz RF Transmitter and Receiver with NPN Transistor Circuit diagram link is hereSep 30, 2015 · A phenomenon called latchup can occur when (1) both BJT's conduct, creating a low resistance path between Vdd and GND and (2) the product of the gains of the two transistors in the feedback loop, b1 x b2, is greater than one. The result of latchup is at the minimum a circuit malfunction, and in the worst case, the destruction of the device.
Recently very popular metal detectors TR-IB (Transmitter Receiver - Induction Balance), or just TR, based on the principle "the handover" (Fig. 1.4). In such devices, called balanced metal detectors, coils are balanced to zero mutual induction. VLF Upconverter for Shortwave Receiver - The schematic above is a simple up converter which I used in conjunction with a short-wave receiver to quite successfully to monitor solar flare activity a few years ago. You can use a 3.5 or 4 MHz crystal for Y1 to up convert from about 10 KHz to 150 KHz to either 3.510 or 4.010 MHz respectively.

Metal Detector Circuit with Diagram and Schematic. Hi Chaitanya refer my comment on August 15, 2011 at 8:00 am Hi Revathy use a MW pocket receiver close to this circuit use an ear phone to listen. now switch on both and tune the pocket radio till you get a silent zone that is empty carrier without any modulation (information). normally without any station tuned in you will get the frying noise ...

The first idea is that a schematic or circuit diagram is only a rough plan or outline. It provides a basis for circuit analysis but it cannot present any geometric information. For example, component size and orientation are missing as are lead lengths and lead dress. As circuits get more complex this geometry is critical.
