RF as weapons.

RF (radio frequency) has many applications since its discovery by German physicist Heinrich Hertz (19th century).

Nowadays, its application is innumerable. We use RF to transmit and receive audio and video signals in wireless telecommunications, as detection means in military thru radar application, an also for household applications such as microwave cooking.

As i m moving into my private research from the start of this summer holiday, i am also researching into RF. My vision is to utilize Rf as weapon against gang-violence and gang bang.

This idea stemmed from a film I watched before. Its a science fiction film where there was a part where one of the character introduces RF when he was surrounded by the enemies, paralysing them temporarily for preset time interval while he remained immortal due to special gadjet he wore on his ears.

I am taking that part of the film seriously as an idea to develop RF weapon, especially for woman who has to walk alone at night and exposed to various gang crime such as gang rape, or just to benefit anyone whether u are man or woman from gang assaults.

Apart from that, I have also gained an idea few years before from a story told by my friend when he watched a pokie machine ( a type of slot machine usually depicting the characters from pokemon series) . He said to his friend ( while i was listening to them) that he felt somewhat sleepy after watching the lights ( notably red and purple lights ) flashing alternately in front of him from the pokie machine.

Again, I took this story seriously as an idea. I bet that alternately changing electromagnetic wave ( light is also electromagnetic wave as concluded by James Clerk Maxwell), or by generalizing it, alternately changing frequency of RF can be used as a mean to manipulate the enemies cognitive function.

However, i am still researching the method to immortalize ourselve from the RF while weakening our enemies with that. I hope by the end of this summer i will come to a fruitful solution.

And btw, Nikola Tesla from his research had succesfully produced a sleep-inducing machine, which i see as an encouragement that RF (or electromagnetic wave) is indeed useful as cognitive-manipulating weapon.

My first working radio.

Just the picture of a crystal radio successfully made by myself. It manages to capture several UK channels, most notably BBC Radio 4 and Absolute Radio. For this project I used enameled copper wire BS6811 (British Standard) for the inductor coil, a Schottky barrier diode 1N5817, an a Taiwanese-made crystal earphone. The schematic of the circuit is not fancy at all; you just type in 'crystal radio' in wikipedia, scroll down to the last line and there is the simple schematic i ve been using.

By successfully producing a working radio, i have accomplished one thing in my long list -to-do-before-I-die: Making a radio. Enjoy the pictures.Its not my final destination; instead its just a start to my arduous journey into the world of electronics.

The overall picture of the radio set. The coil is of utmost importance in this invention since it forms a tuner circuit with stray capacitor ( the wire and surrounding air) and the fixed capacitor ( the blue component explained below)

The circuit. Blue component is fixed ceramic capacitor. Its optional.

The breadboard where i plant all the components. The black diode is not an ordinary diode; it is called Schottky diode. Bought it from Maplin for less than 1 pound ( got 3 of it)

A crystal earphone. This earpiece has a very low internal resistance; hence reflecting its capability of detecting small signal compared to its ordinary counterparts. I bought it from Ebay with about 2-3 pounds ( dont quite remember).

Zoom out view.

Though this radio is going well with crystal earpiece, it doesnt mean i cant use an ordinary Iphone earpiece. If the signal received is strong enuf (happens occasionally, depends on luck) you can use ordinary earpiece with a little press into your ear. Only one side of the earpiece will produce sound since the signal is mono.


Update (13 June 2012): I repeated the crystal radio design and I managed to record the AM signal received. Here is the video. I am still using the same coil with LM386 audio amplifier.The sound was in fact, louder than u will listen from the video.
