Oddily enough, your the second person whos asked about a follow up this week!
So, it does absolutely work. I do have a functional HUD inside my scope. However, it gets lost in bright light and the reflective plastic itself could have been cut better. If i had to do it again, I’d get a perfect oval shape cut with a cricut. Maybe with a notch in the bottom to run the 4 wires. Which brings me to the running of the wires. I had to drill three holes. One in the scope, one in the scope mount and one in the gun itself. I found some ribbon wire that works perfectly to keep it all together. I basically just had to run it through the holes, hiding it along the arm of the scope mount, and glued it all flat to the inside bottom of the scope itself and along the arm. I also had to glue the OLED flat to keep it in place. I never came up with a good mechanism for placing the plastic over the screen, just kind of stuck it in there and pushed it around till i got a good alignment. If i had to do THAT again, id probably 3D print some sort of chassis that holds the OLED and the plastic together at the correct angle (approx. a 45 degree angle) and pop it in the front of the scope, easy peasy. I figured out how to convert movies into a .bmp animation, plus a bunch of .bmps from other blaster systems. Brian and the Proff wrote some code to get bullet counts to work and thats basically where i left it.
I know about the OLED I have seen the code for that surprisingly… And you just need a circular cut prism for that with a bezel to block out some of the light… the issue is with the plastic… You can get some lighter one way mirror stuff… but your best bet is still a prism… it will reduce the source of out side light. and I still would suggest a bezel.
The issue is that the OLED isnt bright enough to stand out against the sun. Little is, aside from a laser. And a prism is indeed also used in HUD’s, but you never fit one inside of a scope, let alone sneak an OLED underneath it. The plastic film i found is actually used in car windshield HUD’s and is able to be cut to fill the entire tube perfectly. When it works, it looks awesome!
This is what I am referring too. you cant totally get custom prisms made. this is just quick and dirty example. But thankfully you can see the reflection in my model when its rendered. the light blue is the OLED screen as you know. But I thought I would clarifly for others. you have the barrel of the scope and the prism. you can get a bezel to help block out some of the light bleed and it can act as mount for everything. And other suggestion is get a camera filter to plug the far end to act as sunglasses or even get cheap sunglasses. boom problem solved. remove it when its not as bright.
Yeah, i like that solution as well! Can you 3D print a prism? Probably not, but maybe? And it does solve the problem of keeping the OLED flat, although you’d have to be VERY careful with whatever you use to affix it to the bottom of the prism. My way is probably more cost effective, but your way is probably easier to install. Although the hardest part of this whole HUD in the scope thing was the drilling of the holes and the running of the wires. The OLED part was actually fun to install.
