movable crosshair osd

Projects General Guidance
1

Hey guys,

first I will describe my plan as a whole and then the problem I have(im total newbee btw)

Project:

I want to build a nightvision scope with a night vision camera ( RunCam Night Eagle 2 PRO - RunCam Store ) and some sort of 1,5" OLED display.

Now, I want to build a OSD device between these two which generates a crosshair, to access the crosshair I need some buttons to move the crosshair to zero the weapon

Cheers,
Daniel

Hi,
Welcome to the Forum.

If you are a total newbee, then this is not the sort of project to start with.

Can you tell us your electronics, programming, Arduino, hardware experience?

Thanks.. Tom... :slight_smile:

First, build the camera and get the image to display on the screen. Then forum members can help with the crosshair display.

Not an Arduino project if you want to process video signal.
And none of this would be approved for recoil if you're using a real firearm.
And hunting with night vision may be illegal where you are.

the problem is, i cant plug the cvbs camera output to the display i want to use

thats where i need help

display i want to use: OLED Breakout Board - 16-bit Color 1.5 w/microSD holder [EYESPI Connector] : ID 1431 : $39.95 : Adafruit Industries, Unique & fun DIY electronics and kits

Its not illegal where i live
i dont want do process video data, i just want to put a crosshair which is movable on a screen
the recoil isnt that bad i assume

i know some programming, enough to programm a crosshair on a screen^^
electronics, arduino and hardware experience tends towards 0

Hi,

And mix it with a video image.
That is video processing.
You need processing speed.

You need to research the video signal structure from the camera, the screen you have is just that, a screen, you need video processing to get from one format to the other.

Also need processing since the camera will be putting out a different resolution than 128x128, which is frankly worthless as a scope picture unless you're hunting barns.

That camera output is a pretty ordinary composite video format (no problems there)
I've been looking at the LM1881 chip or MAX7456 for squirting in an overlay from a nano or pro-mini.
I think the MAX7456 is more aimed at FPV with functions that fit that...
Lots of info knocking around regarding displaying complex FPV stuff so it certainly seems possible to implement a simple crosshair with a zeroing function.

I'm leaning towards the 1881 at the moment but with knowing so little, that could change at any moment :slight_smile:
A ton of reading to do!
