    I'm very interested in your design, looks like you've made a lot of progress.  I got a lot of questions and I hope you don't mind sharing your bits of experience and wisdom.   How  rigid is the camera mounted to the scope?  I get a lot of play in my setup. Are your 3d prints in ABS? did you print them in house or sent them out for printing?  Where's the power source for your camera and lcd?  I found that 16mm lens on my camera gave me a better picture through the scope and I've got a 70mm lens on the way where I hope to not need a scope at all.  Thanks!

    I use Shapeways for printing my models and the their versatile plastic material. Its nylon plastic (PA12, Polyamide). I know Shapeways is on the pricier side but I think its worth it. It's professionally made and its SLS printers instead of FDM printers. 

    "Versatile Plastic is a durable nylon plastic that can be used for a wide range of applications, both for prototyping and for end products. Printed using Selective Laser Sintering (SLS), when thin, it's flexible enough for hinges and springs and when thick, it's strong enough for structural components." (Shapeways.com) 

     

    I find its very rigid but it is plastic and there is some play. Less play then I was expecting though. Some of the play can be removed by increasing the thickness of the bars or putting "pillows" on the eye peice like in the picture. Ideally youd fasten the pillows around the eye piece to for extra rigidity. 

    I use a 3,7V 2000mAh Li-Ion battery and a 3,7V-to-5V power booster with a 1A output to power the Raspberry Pi 3 and the screen. Ive tested a 16mm lens to but the image got to small for scopes but for red dot sights I found that 16mm is the right one. But that only applys to the official Raspberry Pi camera. Different cameras have different size sensor chips. 

     

     

    How are you going to aim if you dont use a scope? Are you going to use a red dot sight or maybe a laser sight?

    Can you post a picture of your setup?

    I'll post some pictures when I get it put back together.  I'm waiting on a new lens at the moment… as to aiming without the scope, I'm borrowing an old counterstrike cheat for hip firing snipers.  Avery makes a little marking dot I plan to affix to the monitor.

    I think I've come to the end of the road with this build. After some testing with less than good results on higher magnification I've decided to stop.

    I will continue to develop the red dot camera. I've come up with a simpler design using an action camera.

    I now have two concept of the red dot camera. One is for standard red dot sights.

     

    The other one is variable height so it can be used with several different red dot sights.

     

    The action camera I am using has a 25 mm lens so it gives me the image I want.

    I'm having the standard version printed and I will post pictures and video as soon as it arrives.

    Testvideo!

    I still dont have the right lens.

    I intend to use a lens that work day and night with same fokus.
