- Super short tutorial on how I made this simple 1:1 scale replica of a WW2 Revi Reflector Gunsight

Teleprompter glass, also known as beam splitter glass, is made by coating a sheet of glass with a special reflective material that allows text to be reflected onto it while still remaining transparent. An inexpensive source for beam splitter glass is a two-way acrylic mirror. Two-way acrylic mirrors are similar to beam splitter glass in that they reflect text while remaining transparent to the person standing behind it. However, they are made from acrylic instead of glass, which makes them more affordable and easier to work with.
For the reflector, you can use either glass or plastic and add automotive window tint film to make a first-side reflector.
Cool idea, I'll have to try that! Thanks!
Awesome! I've always wondered how these things worked. I'm amazed it's so simple. Thanks for sharing.
Very cool, thank you. looking forward to see more!
awesome piece of history, thanks for sharing
Hopefully this video gets blessed by the algorithm, very interesting
adding a diffuser just like in the led mobile display should help a lot :)
honestly this is a really cool video keep it up
Commenting for when this goes viral in 10 years
I would add one translucent sheet in between led and reticle to diffuse the light and reduce the brightness hot spot.
Oh yeah, some velum might work for that. Thanks!
This is very cool! I wonder if you could make a modern jet HUD like an F18/F16 but with a green led and a different templet.
Yes actually you can. In fact you can do better. If you go to thingiverse and pull up this file the author set it up so he could project up his GPS and use it like a HUD while driving.
Both Me and Bf are correct.
The plane started as Bf-109, produced by Bayerische Flugzeugwerke, hence, Bf.
The designer, Willi Messerschmitt took over the company in 1938 and it was renamed into Messerschmitt AG. So it is actually more accurate to call it Me-109.
John, Well done. I did 2 of these with optics and recital provided by Tim Noack. Used actual beam splitter glass which worked very well except for not being full scale thickness, 2mm vs. 6mm. I also drilled out the printed ball locks and installed working ones so the sun shield worked and locked in the up and down position. I will have to look into the clear plastic you suggest as the glass lenses I used were pretty expensive. I tried a 6mm piece of lexan and the ghosting was nasty.
Very clever ! 👍🏻👍🏻👍🏻👍🏻👍🏻
*_Interesting._*
I'm making one of these for an RC me262 to use in fpv headtracking.... I'm doing it with a tiny OLED standing verticle at the back, a 90° reflective prism underneath the collimating lense and a little peice of glass that's designed to reflect like 30%(wut I'm prob gonna try first)
The reason Ur getting ghosting is cause it's traveling thro the glass before it hits the reflective surface and the glass is bending the light and giving U a double image.... You need the reflective surface to be the side of the glass that the reticle is hitting first so the glass can't bend the it.
Trying to work out how to motorised the sun reflector while looking as stock as possible so I can actuate it via remote while flying....
Hey can you give me a list of the materials you used to make this?
was really looking for a video like that, thank you very much! Do you think you could actuslly use like a small lcd screen instead? So it could actuslly shoe like on a modern hud
Yes you could and that would be awesome!!
Could you do this with a phone screen instead of a led and have a more modern hud?
Mount it on a rifle
Thanks for the informative video on reflector sights and research behind it! The concept is easy to understand. But to scale it down to usable size for RC planes yet retain clear reticle image, no ghosting and no parallax involve a lot of intricacies. Simple but the devil is in the details.

I've previously tried printing measuring reticles on film... Honestly, really difficult to get them thin enough on an inkjet printer. I wonder of there's a more effective method of getting really crisp tiny crosshairs made so you don't get this odd light effect where one part of it is brighter than the other.
P.S. I've been hunting for a Revi C12/D replica for years. This might just bring me close enough to making one myself.
you are not printing the tiny crosshairs, you are printing the black space around them. The crosshairs are the clear part.
@@JohnSmith-gm4fj Of course. But the printer tolerances behave in a similar way.
@@darth_dan8886 I am using a old crappy hp inkjet I got for under 100 at Walmart 10 years ago.
@@JohnSmith-gm4fj Which is absolutely usable for this project, don't get me wrong! I'm just saying that as you try making smaller masks and putting them closer to the lamp for a more evenly lit image,, the inkjet might run into limitations, that's all.
Is it somewhat hollographic? i mean, does the center of the center of the cross hair stays more or less "on target" if you move side to side or up and down while watching down the glass? or is just a reflection with no functional purpose?
The reticle doesn't move, it stays right where it's projected. You can move your head around until you see it but it doesn't move with you. The functional purpose is to put it on the enemy aircraft in front of you and pull the trigger. My understanding is that only the Allies had a gryo-compensated sight that moved around but I think that was much later in the war.
@@JohnSmith-gm4fjyou should replace the lens with an actual collimator lens it will make it “holographic” like its supposed to be. Just measure the dimensions and there must be something similar online
@@JohnSmith-gm4fjif the reticle doesn't move.. Then I assume you've got to move your head to put your eyes, reticle and plane in the same line. How is this better than just an iron static reticle? I thought the plane was projected through a lens also along the reticle. This way the pilots head position didn't matter.. You day both the plane and reticle projected on same plane.. You just line them up and shoot .
@@Bren39 it is way easier. It behaves/resembles a laser pointer. You don't have to align your head completely (first advantage) and of course you dont have to align front and rear sights (second adv.)
You just look through a window and find a spot that moves with the airplane (of course you have to fly the airplane to make it point at the target). Once you see it, you can move your head around quite a lot. The closer to the window, the wider field of view you will see the virtual reticle against the real world.
Now it's a matter of matching the ghost reticle and the target. And it feels like a laser.
I know red dots quite a lot and yet I still love to play with them. The unnatural feeling of seeing a dot floating at infinity no matter how you rock your head is always quite interesting to me
Are you planning to attach it to rifle or air soft?
I wonder how good of a rifle sight it would be
no, this would be more for a WWII airplane simulator or maybe even a cockpit sim, if you were to build up the entire cockpit.
You could try putting this on a BB gun.
In fairness i believe BF was the companies before being called Messerschmitt like before the war but there are many contemporary accounts of it being referred to as the me 109 so wouldnt worry its no where near as bad calling leichter panzerjager 38(t), an "hetzer" 😉😂
Yes fair point. The "BF" in BF 109 stands for Bayerische Flugzeugwerke, which translates to "Bavarian Aircraft Works" in English. The BF 109 was a fighter aircraft developed in Germany during the 1930s and used extensively by the Luftwaffe (German Air Force) during World War II. The Bayerische Flugzeugwerke company was later renamed Messerschmitt AG, and the BF 109 became more commonly known as the Messerschmitt Bf 109.
Nice info, just one thing: what about focusing at infinity? How do you choose/adjust the simple magnifying glass to act as a collimating lens? No pilot wants his eyes to alternate focusing between the glass and the target.
To do that you just need to find the focal length of the lens and put the LED at that distance
@@ARandomHumanBein LED or reticle? I think the reticle is the only part that has to be at the focal length.
@@johnbeauvais3159 Yes, the reticle should actually be at the focal length
Is the printed reticle sheet an OHP sheet? Also, was it printed on a home printer?
This was printed on clear plastic ohp sheet on my crappy home printer.
Now it's for DICE and Activision to add it to MP44.
Skip to 9:20 if you actually want to see it work without having to listen to him droning on....next time GET TO THE POINT....making people watch to the last minute is not going to get people to come back to your other videos.
