IR setup

[moulindu]

Hi

The car rear view screen idea seems to be good. But these will be available in car parts shops rather than electronics stores. Else ebay to the rescue!

Essdee da I have checked the ebay store they are ok for tft/lcd screen & wiring but the IR camera is below have to go with bullet camera individually.

Thanks Pratikji my cousin brother is studying in IIT B ,I will ask him to have a check at those products, by the way do they ship it outside Maharashtra?

Well after lot of search of the proper attachments my pretty lady is almost ready for the party. Haven’t shot any pellets through it as the building process took most of the time. Since waiting for the next world cup match & need to keep myself busy thought of posting some of the pics. The power source (battery) ordered from DX got sent back by customs, so had to make temporary solution using a 12V, 7Ah battery from by bike. Though it is not handy but at the time of despair it helped me setting up the rig. I adopted the idea from Rolaid (Youtube) & I really thank him for such a nice innovation. Not sure whether it will sustain the recoil of a springer, but keeping my fingers crossed and hopefully it will work in my favour.

With IR Illuminator

Hi
Here is the cleaned up version of the NV setup. The final addition is the battery. Viewed but not shot at a distance of 25mts & it is more than descent in identifying the target. So here are the parts used in building the rig

Camera: - The bullet camera used is 1/3 SONY 700TVL with 12 mm lens (rating 12v, 60mAh). It has sensitivity to capture pics at 0.0003Lux. The IR filter of the camera is removed by the seller so as to view IR light. The dia. Of the camera is 20 mm so shim is provided using medical tape. It is fixed behind the eye piece at the best possible eye relief. It is attached to the rail using 1” mount.

LCD/TFT monitor: - The monitor has 4.3’’ screen with both NTSC & PAL input facility (rating 12v, 70mAh) . Its a colour monitor used for rear view while parking. I have purchased a camera mount adapter with 2 holes on the top. I drilled a hole on the base of the monitor stand & fixed it with a nut & bolt to the adapter. The adapter then sits on the picatinny rail.

IR Illuminator: - IR Illuminator/torch or laser is of 840nm wavelength with 5watt capacity & requires 3.7 v. 18650 battery. There are many options for power for the IR Illuminator/torch from 2, 3, 5 watt etc. The more the power the quickly the battery will burn. Bought 3 of those batteries having 3000mAh along with a charger. With each battery the illuminator runs for around 1hr.

Battery: - For powering the bullet camera & monitor I bought a 12v 4500mAh Li ion rechargeable portable battery. It is of the size of an external hard disk. It comes with a charger & chord for power supply for only single source. Have to make a 2 way splitter & save some penny or can buy a splitter from electronics shop. Got a pouch prepared from the leather shop for accommodating the battery. Stitched Velcro to the bag straps & stitched the strap to the pouch for holding it to the gun.

Picatinny Rail: - Bought 2 picatinny rails 1 measuring 25cm & other 15 cm & couple of pairs of 1” picatinny mount. If the length of the longer rail is more than 25cm then it will interfere with the elevation turrets, in that case mount risers will help. Used araldite to fix the rails from one end (one can drill & tap as well). The longer rail is kept downwards & at the end the bullet camera is fixed at suitable eye relief with the scope using a 1” mount. The other end is fixed with the scope in the upside down way. The shorter rail is used to attach the IR Illuminator in the front (using a 1” mount) & LCD/TFT monitor in the end with sufficient space for changing of battery.

Congrats man it came out really well. I'm sure it'll be further miniaturized in times ahead. It helps to minimize any plays that'll creep in.

Some way to record the action would be a cool plus.

Get under a black wrap & go for the kill. Cats, dogs & ghosts would still see you though! Or if lucky, you might end up seeing that last kind!

[moulindu]

Hi
Thanx man

Some way to record the action would be a cool plus.

yes you can mount a DVR instead of a LCD/TFT screen & record the shooting but it might cost a little more. my total expenditure was around Rs 12000 with shipping.

OOO afraid of them, but got invitations from my relatives to eliminate the rodent problem after they saw my termination of rodents at home

& now that u said rigging, the setup reminds me of this! The OSA Snooper rifle from Return to Castle Wolfenstein.

Hi estousandy
Thanks for taking me down to the memory lane. Played this FPS (First Person Shooting) game a lot during my college days, but now FPS means a whole different thing for me now
Well i have couple of links for your interest

The problems may be custom interfering with the package as they will definitely think NV are deadlier weapon than scopes.
Price can be taken into account with considering shipping cost & import tax (if at all they let NV through) & the last of all is it might not be springer rated so have to be specific to use on a PCP

The rodent terminator did get loose last weekend & bagged 8 mice with 2 nights sitting at my uncles place of around 6 hours. Dont want to break any rules but if admin permit would like to post few pics.

Please go ahead man. I guess here vermins are expendable.

And yes, importing those NV gear will definitely get law abiding citizens in trouble. Not so much for baddies.

A plug. This is something i did back in my early college years. A very rudimentary night vision setup with whatever was available lying around. More details in youtube description.

A very remarkable DIY Sandip!
Can NV work in 'pitch dark' or it does only on low light?
Just curious
Briha

[estousandy]

Thanks Briha! : )

I used Active Illumination, ie bathing the field with Infrared beam. Its reflection is captured by the cam sensor so it'll work in 'pitch dark'. Note the video description:

A very low cost setup using a cheap logitech webcam with IR filter removed, 8 standard remote class IR LEDs stuck around cam, motorised(gear) swivel mount & a FW/BW wired remote control from a cheap toy car.

The downside is, eventhough mostly invisible to naked eye, these standard IR LEDs are very weak and emit a faint red glow when observed upclose. Also, it can be easily picked up as a bright spot by animals & other cameras.

Solution to this is passive illumination which uses image intensifier tubes but then it goes into prohibitive cost & export restrictions. IA use it alot in ops.

@moulindu used a similar active illumination setup in a much much more refined way with the correct gadgets, and adapted it for another specific task.

Hi
Impressive Sandy, have u tried to range its illumination with or without a scope

Solution to this is passive illumination which uses image intensifier tubes but then it goes into prohibitive cost & export restrictions.

Well there were no issues when i ordered my IR torch, but should specifically go for 840nm wavelength as the 9 series are visible to animals. Though there is a faint red glow in the torch but a distance of 10 to 20 mts its hardly visible or atleast in my case the vermints didnt see it coming.
I have got a site in india for IR torches check it out
http://lightorati.in/flashlights/ir-lights.
or you can always get one from aliexpress or DX
Another way of mounting a rig is "YES" the way u did your rig with a digi cam with the IR filter removed. Here is the link of those vdos

One can mount that digicam to the scope using a "Seben DKA2 Camera Mount"
http://www.ebay.com/itm/Seben-DKA2-digi ... 588b0f258b

The camera will serve the purpose of both capturing the image & displaying it on the screen. The only thing one will have to do is get an IR torch fix it to the barrel like normal illuminators & VOILA you got a NV rig of your own. Very much doable & affordable. Actually I am planning to do this on my IHP.If i miss something let me know guys.

I don't think those IR LEDs illuminated anything more than at 6mtrs. Scope was a fantasy object back in those days.

Well there were no issues when i ordered my IR torch, but should specifically go for 840nm wavelength as the 9 series are visible to animals.

Moulindu, IR illumination comes under active illumination which is not at all restricted. But passive illumination using image intensifier tubes is totally different which doesn't need any kind of IR illumination, but needs some kind of low-light like starlight. It is mostly used in mil sights and is closely guarded. Checkout this video.

Also, never knew about 840 vs 9xx nm advantage. Thanks for the tip.

Great catch man! These pests are so pesky, except the one from ratatouille
