can somebody tell me how can i prepare a night vision scope in home.what materials will be needed & how it will be prepared?on what principle does night vision binocular works?

True night vision requires an image intensifier tube and a high-voltage power supply. You can adapt many digital cameras and camcorders to infrared use, which will enable you to see in the "dark" with infrared illumination that you provide (infrared LEDs from Radio Shack being a ready means).

Many of these cameras have some sensitivity to infrared already, which you can determine by checking to see if you can see the light from a TV remote control in the camera. Further improvements in sensitivity can be gotten by removing the IR blocking filter from the camera, though this can be a tricky operation.

Where To Find A Night Vision Camera?

well, i want a Night Vision Camera or night vision add on for digital cameras. I want one that looks normal, kinda like the ne they use n The Othersiders or whatever. But if you can find one that looks like a normal video camera then that would be great!!! thank you!!!

You want Sony Nightshot.
This is pretty much a standard feature that Sony offers with most of their handy cams and digital camera’s now.

Very simply, Nightshot allows you to take an image in complete darkness, in the absence of any available light.
Nightshot makes these cameras instantly IR(infrared) Modded, and with the flip of the switch, it goes back to the Un-Modded color capable “Normal” state.

Yes, flip a switch and these cameras remove the internal IR Block Hot Mirror filter for IR Photography, and then flip it back, and the IR blocker filter goes back into place for regular Color Photography.

I hope this helps.

Good Luck and enjoy.

vision problems and odd symptoms (but i have perfect eyes)?

February 24, 2010 - 3:40 pm 4 Comments

Hi!

I’m a 26 year old male in the northeastern USA. For the past 10 months I have had the following symptoms, most of which have gradually been getting worse:

(1) flickering / spotty / pulsating vision – i.e. looking at a white wall gives me mild moving flickering dark spots, looking at a dark wall gives me the same except the spots are light. these are not floaters – their edges are very indistinct and i can see through them very easily. this is more aggravating when i am trying to read text, but it is always there.
(2) a more constant dark spot in the very right side of my left eye’s field of vision
(3) occasional ghosted text in both eyes (intermittent bilateral monocular diplopia??
(4) occasional blurry vision
(5) frequent general out-of-it feeling: i feel tired all the time, have constant mild cold symptoms, occasionally feel disoriented, lightheaded, nauseous, or have an upset stomach.
(6) frequent hives
(7) really bad headaches for the past month

here’s what i’ve done so far to check:
(1) GP has standard bloodwork done and resting EKG done. everything is fine.
(2) Ophthalmologist examines eyes, says everything is fine, implies that maybe something is wrong with my brain.
(3) Neurologist does exam and MRI of brain, says everything is fine.
(4) Neuro-ophthalmologist does eye exam, says everything is fine. Tells me I should see a psychiatrist.
(5) Allergist cannot explain hives – allergy skin test is negative

My questions and insights:
(1) Could this really all be stress / hypochondria? If so, what can I do about it?
(2) Over the past five years I have had unprotected oral sex with about 4 different people. Could this somehow be HIV or some other STD?
(3) I’ve gotten sick this year more than normal. Six months ago I had the worst diarrhea of my life, and three months ago I had a week of shivering and night sweats, which I’ve also never had before. I assume this was just a nasty flu – but could this all come down to some disease like Lyme Disease, Diabetes, or Encephalitis? Would my normal blood work have indicated any of this?
(4) Should I go back to the neurologist and insist on getting an EEG to rule out other brain-related things? Should I repeat my MRI?
(5) I’ve also had a sore neck for the past 5 years and occasional unexplained chest pains (doctor says it’s just stress). Could all of the vision issues somehow be related to disrupted blood flow to the brain or pinched nerves in the neck?

Thanks for the help!

Since you have been examined by so many specialists in fields pertaining to you exact problem you situation is difficult think of as organic.
You seem to have a lot of potential causes, most have which would have shown up in simple blood tests. One thing you can look into is any medication or drugs you may be taking. Anything that thins blood can cause a minor bleed in a blood vessel that shows up as a dark spot that resolves in time.
On the other hand I remember a little girls telling me she could see air at night in the dark. You could be overly conscious of the normal things people see but ignore. You may see them more vividly but if a person stares at tiles or walls they can seem to move. You must be reading medical books which is giving you something to worry about.
I think you are tying together different minor symptoms to come up with a cause for something that can be normal.
I don’t see so many specialists missing the diagnosis. I hope i am correct and your symptoms resolve.

Nikola Tesla (1856 – 1943) was a noted inventor, scientist and electrical engineer.
He invented Tesla coils, alternating current electric generators and was a major early pioneer of radio technology.
He was also noted for making some remarkable claims, among them that he had developed what he called a "teleforce" weapon.
The press called it a "peace ray" or death ray.

Cheap Night Vision Goggles – Where to Buy Cheap Night Vision Binoculars

February 17, 2010 - 2:37 pm No Comments

We humans cannot see very clearly in the dark and that’s why cheap night vision goggles can be pretty useful in some cases. Don’t worry about the “cheap” attribute because there are some designs available on the market that offer good quality for less money.

If you decide to buy yourself a pair of night vision goggles then you should try one of the following locations:

Night Vision 4 Less has a wide range of products but unfortunately the prices are not cheap as you may hope but the Generation 1’s is considered to be the best deal.

For both monocular and binocular night goggles the price starts from $269 and goes up to $649.00.

- The ATN-VIPER-1 model costs only $269.00 and offer some great photography options, high resolution, heavy coated glass lens, small size and 1x magnification.

- The most expensive spectrum is the NOU-D-2MV and will set you back no less than $649.00 offering stereoscopic vision, binocular vision, a lightweight set-up, built-in photocell and an optional 3x magnification kit.

- For the same amount of $649.00 you can buy the RIG-3250 dual-ocular goggles. According to the manufacturer, this model will allow you to see very clearly even in total darkness because it features special cups that block light from the sides, an infrared illuminator and individual focus for each lens. Also if you’re in James Bond mood and you want to spy on someone, you can add a conversion pack in the game and use the goggles as binoculars.

A brief analysis of the offer points out that the above mentioned models are the most affordable ones but if you’re looking for something exquisite you can always choose a more expensive pair.

Other selection of night vision goggles include :

First in line comes the Yukon NVMT model that costs only $299.00 offering rubberized and waterproof set-up with infrared illuminator and 1x magnification.

The top model – the Rigel Optics LED, Day & Night Vision Goggles Emergency Set – is priced at $999.99 and offers special gear for emergency response professionals. The package also includes two sets of spare batteries, a conversion kit, laser pointer and flashlight.

There are also many other places online such as ebay that offers discount night vision goggles for everyone.
