Do you have any field test pictures? Performance in the dark, this might be a cheap and usefull way to improve boar hunting

What are you using for a power source? (For field use, not testing)

Awesome work! building and posting one of these has been on my todo list for a while, though I questioned how far I could get an illuminator to reach, and how practical this would be for actual 'field use. but you seem to have no issues with these things, and it looks like a very tidy package. I will have to try this out sometime, I think I have some old analog camera without an IR filter somewhere.

What airsoft are you using? What scope you mounted?

That is my AR15 300 AAC blk. The scope is an old ncstar 3x9x40 I had laying around. I don’t have a link for it because I ordered it a while ago and was making use of an old scope. Just measure the diameter of the eye piece with a micrometer and print the tube part that fits. If you need a different diameter, let me know and I’ll try to get it modeled up and posted.

I would suggest a picatinny style base on the LCD...take it off of the scope tube, and open up a lot of mounting options. You also might consider including a dovetail style rabbit around the LCD, so a cowling could be added, to help cut down on ambient light AND light bleed from the LCD.

All around, a great concept.

Good selection on the camera, I will look in to some other LCD options and send you what I find.

Good suggestion. When I get done with the assembly instructions I'll work up an alternate "Mount" part with with a traditional picatinny rail clamp. Maybe an additional "back plate" part as well with horizontal gussets for a side mounting/ fold in option.

I intended to use the red filter (forgive the instructions have not been developed that far yet) to decrease lighting at night and act as a shade during daylight conditions. I will give this some thought though.

Ah I see, It slips over the rear of a normal 39mm scope, focal length of camera is where eye would normally be so the magnification of the scope won't be thrown off..and the rear has clamping ears to tighten down snugly...very innovative design!
Another idea..make multiple scope tubes that can be printed to fit the myriad of different diameter eye pieces of rifle..er...airsoft scopes

Looking forward to the rest of the instructions for this, I've often thought about building a decent night vision setup, I Will be watching, Thank you.

I'll be working to finish up this week and hope to get some real world feedback about functionality. I'm curious about peoples choices for power supplies and how this tolerates recoil on different calibers etc. So far, I've been able to keep the build under 40 bucks so it shouldn't be cost prohibitive for people to experament.
