Vishualisation of EM radiation

Is there any possibility f observing any radiation other than light
with our eyes?The answer is yes, but our bandwidth is limited &
the light sensor (eye) we have senses only the radiation falling in
the range of bandwidth.So a possibility is here to translate the
frequencies we want to observe to the frequencies we can see.Such
a device may make sense in the later world ,but now it may feel
not digesting.Me and Arun Prabhakar observed the IR rays with
the help of sony erricson mobile camera,even though the actual
reason ,we didn't know,the process happened anyway.After some
years there will be ppl wearing some helmet that could permit
easy view of the whole em spectrum.

Hello. This post is likeable, and your blog is very interesting, congratulations :-). I will add in my blogroll =). If possible gives a last there on my blog, it is about the Câmera Digital, I hope you enjoy. The address is http://camera-fotografica-digital.blogspot.com. A hug.

LDR :-Light dependent resistors

A Light Dependent Resistor ( LDR, photoconductor, or photocell) is a device which has a resistance which varies according to the amount of light falling on its surface. They will be having a resistance of 1 MOhm in total darkness, and a resistance of a 1 to 10 of kOhm in bright light. A photoelectric device can be either intrinsic or extrinsic. Applications: An LDR can even be used in a simple remote control circuit using the backlight of a mobile phone to turn on a device - call the mobile from anywhere in the world, it lights up the LDR, and lighting can be turned on remotely! Light Dependent Resistor Circuits: There are two basic circuits using light dependent resistors - the first is activated by darkness, the second is activated by light. In the circuit diagram on the left , the led lights up whenever the LDR is in darkness . The 10K variable resistor is used to fine-tune the level of darkness required before the LED lights up. The 10K standard resistor can be changed as require

VIRTUAL KEYBOARD

The Virtual Laser Keyboard (VKB) is a revolutionary accessory (The only keyboard that operates in total darkness - see the picture below) for Blackberry, Smartphone, PDA, MAC & Tablet PC. These are virtual keyboards that can be projected and touched on any surface. The keyboard watches your fingers move and translates that action into keystrokes in the device. Most systems can also function as a virtual mouse. Keyboard projector A holographic element illuminated by a red diode laser produces a template of the keyboard. Illumination Module An infrared plane of invisible light is generated just above and parallel to the surface of the keyboard.When a key is touched light is reflected from this plane and directed towards the sensor module. Sensor module Reflected light from the illumination module is passed through an infrared filter and imaged on to a sensor chip which determines the location of the light.It can process and interpret several keystrokes simultaneously.

When can we expect personal virtual assistant drones?

 Virtual Assistants such as Alexa , Cortana are commonly used these days. They are  capable of voice interaction, music playback, making to-do lists, streaming podcasts, setting alarms, playing audiobooks, and providing weather, sports, traffic  and other real-time information, such as news. Some of them can also control several smart devices. We are also familiar with drones these days.  Why not combine the power of Virtual Assistants and drones and make something called "personal virtual assistant drones"? The key challenges of creating an integrated system like this is the energy requirement. Batteries having high energy density needs to be used for these applications. With the newer Li Polymer batteries we can build prototypes of these.  These assistants can serve the computational as well as recreational needs of people. With the growing demand for integration and scaling down of product dimensions this seems highly achievable.
