Any body want to share their DIY Night Vision project?

Here is my latest;
This the next generation of my DIY Night Vision Scope. I redesigned the housing surrounding the camera body to affix the lens and make the entire unit rigged. Here is my drawing,



This was the hardest part not having a legitimate mill to work with.



It all came together nicely and will be ready to field test soon. Could use some pointers of how to get a decent finish on the housing though?



Here's the camera and lens which is a 120mm and not 150mm.


Here it is all camoed out and ready to mount on the rifle.



Finally got to range test my DIY night vision scope Frankenstein II. I mounted the scope on my newly acquired Armalite A10T 7.62 X 51mm. Oh this rifle is sweet to say the least. There was some concern the electronics would not stand up to the shock of a large caliber weapon so I was pleased I had no issues even after 40 rounds.

I discovered several things that I overlooked. 1st Forgot my spotting scope at home. 2nd. Was when you remove the IR filter from the ccd in the camera it becomes color blind. So the standard Alpine Orange targets were mostly invisible through the scope. Luckily I had a black Marks-a-lot and was able to draw a bulls-eye the scope's optics could pickup. The resolution is not quite what I hope for with the 120mm zoom lens and I will say 100yds is probably its limit. I was able to line up the target and put together a decent group but I question whether I will be able to distinguish a doe and a button buck at this resolution.

So here is what Franken II looks like on the A10T:


Here is target of 2, 3 shot groups. The first group are the top 3, the bottom 2 are after adjusting the POI down 1 pixel, there is actually 3 shots as two are basically in the same hole right above the bulls-eye.


So what you see cost a little more than $200 and my machine time. With IR illumination it can see in total darkness out to 200yds. Next up is a hog hunt in a few weeks, hope to have video for my next update.

I can't believe I'm the only one that has done this. I know Hard-Ware has a cool thermal unit. Is there not anyone out there with a scope based on this technology?

Well, now you got me wanting to build one, I like your set-up.
I would just paint that thing black.
Is the screen a little too close to you while shooting? Would it be better mounted on top of the camera so that it isn't right in your face?

Im still waiting on parts for my build. I will be trying it with my scope first ( so it can be taken on-off easily and still be used "normally" ). I figure there will be some issues with light transmission through the scope but......also I have put together an illuminator using a Osram Golden Dragon IR LED with a 1000ma driver to be mounted on it. With this LED I can see about 125yds using an old Sony Nightshot camera. Most of my stuff has come in but still waiting on the camera and BNC/Rca adapters etc........

Here in Texas, there don't seem to be too many, but this is more popular to do over in England based on all the creations that show on the NV UK forum. http://www.nightvisionforumuk.com/

My hat is off to folks like you who have such talents and time. That is some neat stuff.

We now know what the "Slow Boat From China" is all about, don't we?
I Ordered 2 UniqueFire T20's from WallBuy's. The T20's are in customs going on a week, however, I received the two 940nm pills from the guy in Great Britain in 5 days. So I have everything needed to complete the second scope and think I can have it up-fitted with mounts by Friday.

By the way, this last camera I received had the IR Filter glass that overlays the CCD cover glass glued with a superglue like material. It was a real chore to get it off and I eventually had to chip the glass off the top of the sensor housing. You have to remove it if you want to see light above 890nm. The 3 cameras I had removed the filter before were held in place with a soft almost pliable clear gum/glue. Not this one, it was stuck solid. Only way to get it off was to chip both layers of glass.

I didn't realize that about the IR filter. At this point I am using a 850nm LED so I should be good. I have been tracking my package and it actually made it to the US pretty dang quick, I think it was here in 2 days but then there is waiting on customs, delivered to shipping partner etc. Been sitting in NJ for 3-4 days now.....

A couple of questions, if you dont mind. My stuff came in and I was playing with it last night. I noticed ( as you had stated in another thread ) the loss of light when using the camera through a scope ( I believe you had done the same in your first build ) so will probably go scopeless like you. Do you just set the zoom and focus and not touch it after it has been sighted in? When I zoom the crossshairs move. I figure I will zoom to get a good view at 150yds or so, focus then lock them both down. Last night I was able to see well out to maybe 80-90yds through the scope and I gained about 20yds without it. My weakness is the illuminator. The Golden dragon LED is only like 500mw and the optics are poor for this application. Im going to have to order a T20 and Osram Oslon LED and put it together myself, I cant stomach $150 for light right now.....

What lens do you have? If you look at the photo above you will notice cap head screws at the front of the scope. Those are there to affix the front of the lens so it can't move. The OD of the lens is about 3/16" smaller than the ID of the square tube. Once together I used a laser bore sight to adjust the screws to align the scope before going to the range. The back screw that mounts the camera body to the picatinny mount goes all the way threw the square tube. The front screw of the picatinny mount has a little tolerance so the base can be swung a degree or two for alignment.

Once the lens is set you will be able to zoom in and out without moving the POI. Now if the scope is not aligned true to the bore because you don't have a laser bore sight then the POI may move. In that case just create a second set of cross hairs for the second distance.

Just finished the second scope last night so I will post up a few more pics of how I mounted the camera to the tube/picatinny base.
