homemade night vision

[georgenottingham 7]

Hey, after watching the latest episode of fieldsports on youtube about homemade night sights it got me thinking. They couldn't do it any cheaper than around £70. I got on ebay and noticed you can get an ultrafire with ir filter for 25quid as an illuminator. Bargin right? Uh uhhh! How about 7quid for a 30mm cammera ir pass filter that will fit most compact ultrafires! All one would need is a video camera with night mode. Which most may already have in the man draw along with old keys and take away leaflets. Any thoughts on this?

ir pass filter for the camera? extra 5-10quid, when you can remove the sencor filter as is on most

 

the ir filtered untrafire? would have to be a xenon bulb as white LED's or coloured LED's dont give off enough IR to do out with.

 

the cameras dont pick IR half as good as intencifier tubes, so its a careful selection for IR torch's off ebay

 

the batteries from ebay quite often stop working, its one of the circuit bits that cacks out..unknown to resolve, the blue rapped packs i'm told dont go bump.

 

now DSA the thing..30 quid cheepest for a proper one, and although exstremely easy to DIY, becomes a chore getting it right.

 

70 quid? yes very posabley if you know what to buy first time...if.

 

20 quid camera, 30 quid DSA 20 quid batteries, tenner fu bits, and for the IR? 15 if your lucky for airgun ranges, up to about 75 for a desent one (150 quid shop bought), and 13-29 for a reversing screen, then from 5-150 for a lens, 5'ver for a lens mount posably..so yup 70- quid a first buy, but dnt exspect to be seeing too far..rat bash's a yes, 50 yard bunnies? you'll be lucky but tis posable for another 20 or so and a driver 5-20 quid..focusing lens 3-50 quid.

 

some of the 5-10 quid cmos cams do well, but the image quolity sucks more un your grandma on boiled eggs lol.

 

have a google and read through a few of the forums, watec and a lardy light seem the way to go for better distances.

 

any camera wont do diddly.. 0.001 lux it starts to happen when you have a desent IR source. forget the 950nm led's..and forget 157 through the hole LED's, your lit up like christmas in red lol.

 

filtering a tw@t lamp works nice though. it's getting enough IR nd enough zooom to see it on a camera, the scope does subtract a bit light to start with, so up the scope zoom on the bottom end stuff and it goes black very soon.

 

thats the jist so far..lol
