There are still neighbors that keep annoying you by having loud the TV or the radio? Well I have you the solution. In fact all neighborhood will face your jamming waves at their TVs and radios, so be careful. This Jammer is the improved version of the old "TV and FM jammer schematic" with the difference of much higher power. Many of you where asking for a stronger and wider effect but to be as portable as can be. Looking at the schematic you can see that, only the.....
If we are speaking about professional Cell phone Jammers we are talking about this schematic below. First off all you should be very careful how to use this device. Its fully illegal and so the purpose I post this Circuit is only for educational and testing reasons. This type of device is being used by security for VIPS, specially at their limousines to avoid bomb triggering while the car passes from the target cell phone-bomb. Offcourse there are those who use it to make.....
This converter enables reception of 800 to 1000 MHz on any scanner covering the 400 to 500-MHz range. The converter can be set up to cover either 800 to 900 MHz or by readjustment 900 to 1000 MHz. Sensitivity is very high because of the GASFET front end. ..
In this circuit, an HA-4900 series comparator is used in conjunction with a D/A converter to form a simple, vers..
The LM380 operates as an astable oscillator with the frequency determined by R2/C2. Adding Ql and driving its base, with the output of an LM3900 wired as a second astable oscillator, ..
The PA41 from Apex Microtechnology is used here to drive a piezoelectric micropositioner...
The HA-4900 series comparators can be used as versatile logic interface devices, as shown in these circuits. Negati..
This circuit uses 1/4 of an LM3900 to build a simple variable-gain front end for an oscilloscope. R7 is the gain control. Also shown is a simple preamp..
This circuit will produce over +10 dBm in the 1800-3 000-MHz range. Drive power is 7 dBm in the 900-to-l 500-MHz r..
