DIY radio drone jammer

The oldest sort of radio transmitter invented by man is the spark gap transmitter. They function as jammers for the same reason they were outlawed: they monopolize a large portion of the radio spectrum.

A spark gap transmitter is an easy device. Send a high-voltage current through an air gap, and a spark will cross the gap when the resistance of the air breaks down. Electromagnetic radiation is emitted when this happens. You may simply test this in your own home. A stereo set to CD or tape with no CD or tape playing will work, as will computer speakers that are turned on. If you quickly turn on and off the lights in your room, you should hear a clicking sound from the speakers. The clicking is caused by the light switch picking up RF energy.

This type of spark gap generator is rather easy to build. The following things are needed: source of high voltage, batteries, a little piece of wood on which to mount objects, a tiny engine, a few screws or nails, and a wire.

A high-voltage source could be an ignition coil from a car. This boosts the voltage from the battery or alternator, causing it to jump across the electrodes of a spark plug, igniting the fuel. A spark plug is a spark gap, and while it isn’t appropriate as a radio jammer in its current form, it may be turned into one.

All it takes are a few steps.

First, assemble the motor.

After you’ve put the insulating block on the motor, secure two more nails or screws on either side, near enough to touch the cross members you installed in the previous step.

Make sure your antenna is ready. This is a piece of wire that has been cut to 1/4 wavelength of the desired frequency. Connect one of the stationary side rods to the antenna(s) you created. You’ll need to connect a ground to the other end.

Connect the ignition coil’s output to the stationary rods on both sides of the motor. Connect the positive terminal to the antenna side and the negative terminal to the ground side(s).

The battery must be connected to the motor and coil as the last and last stage.

You may either install a switch or just disconnect the battery to turn the device on or off.

After that, enjoy your DIY drone jammer!
