Power supply adapter of cell phone jammer should be more than 20cm away

Common optical zoom cell phone as Samsung and Sharp, LG, and not a lot. It is recommended not to be easily used in the filming the 7710 digital zoom function. STN is the main devices of the early color, initially only display 256 colors Although technological innovation can make the display 4096 colors or even higher with 65,536 colors, now STN screen or 256 colors, the color is not very good. brightness is not high, generally sunny place, the image looks very tough, his advantage is low power consumption, cheap. Cheaper domestic color cell phones on the market today are based on this screen material. The directional antenna of cell phone jammer  can be used if reducing interference with outside environment is needed. The advertisement playercell phone jammer hidden in it, The decimal point is fixed in the 10-digit LED digital tube current through R16 to the decimal point "dp", so that the decimal point "dp" is lit. We buy components to the electronics market, taking into account the price and selection of components for the colored ring resistance, a small electrolytic capacitor polarity capacitor, tools 60W ordinary heat soldering iron one, pliers, screwdriver, and so on. After a series of ready, welding is the most troublesome hurdle, the first welding welding resistance, then welding capacitance, and then welding rectifier, and then solder the potentiometer, and finally solder the transistor. Should be noted that the welding quality welding, to avoid cold solder joint, the last check, timely patching. Power supply adapter of cell phone jammer  should be more than 20cm away from the host of cell phone jammer .
This amplifier board debugging is extremely simple to weld electronic components, circuit boards, to double-check the circuit board with or without welding the wrong place, with particular attention to the polarity of electronic components such as electrolytic capacitors, bridge rectifier heap, once the welding anti-namely, burned components of insurance, please pay special attention to. Before commissioning the first quasi-0 ℃ ice water to 100 ° C boiling water. Debugging as follows: will be transferred to the boiling point of the potentiometer tunes the top, so that Vref is the highest voltage, the diode temperature probe placed in the 0 ° C ice water, adjust the tone boiling freezing point potentiometer, so that four LED digital display readings for "00.0". diode temperature probe placed in the boiling water of 100 ° C, adjust the tone point potential, making the four LED digital tube display reads "100.0", and the MC14433 15 feet 0R high.

After the above debugging, the thermometer can work properly, its temperature range is -50 ℃ ~ 150 ℃. Temperature range of the thermometer is only limited by the diode temperature probe, if the switch to the other temperature sensor, you do not need to change in other parts of the circuit of Figure 3-2, you can get different temperature range of digital thermometer .
