You could add a laser range finder to the sight so that it can automatically adjust the correction radius for the reticle based upon the distance to the target.
Thank you for your comment! For airsoft, I would like to measure up to about 60 meters, but those parts are still expensive. I'll take the challenge when they're less expensive. Airsoft ballistics seem to be quite complicated to calculate because they hop and then fall. But that's why it's so interesting. Thank you!
@@Kousaku_Japan Well, if a LRF is not an option you can have a conveniently positioned switch (or lever), that allows you to manually alter between a preset number of ranges instead (a sort of holographic version of some of the iron sights with range zeroing abilities, like the AKM for example).
@@Kousaku_Japan I think 30m is good enough for Airsoft. Especially with 1J laws in Japan. In the US, for outdoor games, we use 400 FPS with .20g BB, which is ~1.5J. Most of the fields in Southern California have very long sightlines, so there is benefit for a rangefinder system, but then again, it's just a game in the end. But I think I enjoyed playing more in Japan because it hurts less with 1J, so you can try more risky tactics.
This is incredible. As an American, a shooting enthusiast, and a gun collector, this ticks a lot of aesthetic boxes for me. Honestly, if you decided to sell these, even if they weren't incredibly practical or durable, they would still sell not only to folk who think it's cool, but also to the cosplay market too. I can't tell you how many cosplayers would love to have a working HUD on a sight for their cosplay weapon.
RFID ammo counts would be cool. Since mags have a standard capacity, you could read an ID, know whether it has been fired and count shots on a per-mag basis.
@@Penguin-1966 you could put N or NW for north or northwest or SE for southeast in a corner of the sight. Also for the range, you should totally get a laser range finder and dial it in with that tilt compensation in your sight! Your build is so cool!
Thanks for your comment. Sorry for my late reply. There are still many improvements in practical use, but it was fun to operate it. New versions are under development. First of all, the small version. I also want to make a multifunctional version with a rangefinder added after that. I hope you will wait patiently. Thank you!
This has nothing to do with parallax free. Put the sight fix on a table and point on a target. Now move the camera. If the Point stays on the target, it is parallax free.
Thanks for looking! I don't think it's possible that no one has ever thought of this before. So I'm sure there must be some practical problems with it, like the OLEDs not being able to display properly when they get wet. I'll think about commercializing it when it's a bit more durable.
combine it with a programmable ballistics computer and make a useable interface you could sell a basic version for like $1200 if it's not a piece of crap in terms of durability bonus points if you make a magnifier option for it
Thanks for your comment. The remaining bullet count display function is interesting. I started planning for the next version. I want to create a cool sight by incorporating various opinions. If you like, subscribe to the channel and watch it regularly. Thank you!
@@JohnDoe-rx3vn Well there's this tachyonelectronics.com/ it's a ammo counter. I'm sure he can incorporate that into his design. Remove the counter & implement it's function into the sight using the sensor.
Now imagine of you put it inside a long range scope and the ballistic computer even shows you the trajectory of your bullet on your display (the newest ones are already advaced as heck but I don't know if they can do that)
This is a very cool idea but you may find that it is better applied to other uses than as an optical sight for the following reason: Parallax. If you cannot set the parallax of the OLED screen out to 100M then the user cannot both, focus the sight, and the target together. One will be out of focus. Most reflex optics are set to ~100M/Yds. Some are set even closer (for pistol use). The advantage of a true Holosight is that the hologram is actually parallax free and remains perfectly in focus when you concentrate on the target at any distance. The reticle in a Holosight will remain the same size no matter where you put the sight on the rifle. The 1MOA dot in the center of a real Eotech is actually ~.33 MOA and even under a 3X magnifier will appear to be 1MOA to the human eye. There are other design considerations to keep in mind when making a miniature aiming system. Keep up the good work!
If someone can make the body out of milled steel and someone else can come up with an intuitive software solution to interacting with the optic’s parameters, you have a pretty good product on your hands
Steel? Nah. Aluminium, sure. 7075 is as tough as untreated mild steel. I work in R&D in the defense industry and could help you out with milling if you want @工作ジャパン Kousaku Japan
If you are ready, maybe send it to some american gun channels like "Demolition Ranch" , "Jerry Michulek" or "T Rex Arms" for promotion (And maybe a bullet counter with an accellerometer that detects recoil)
Thank you for your comment! This sight has shrunk a bit because I couldn't get past its weakness of being difficult to use in bright light. My current push is this one. th-cam.com/video/qnoximEMF68/w-d-xo.html It's not practical, but I think it has impact. What do you think?
Thank you for your comment. It's a reticle adjustment function! I couldn't do it because I didn't have the technology to insert a physical button. Certainly adjustment function is necessary! I would like to include the next work. Thank you.
Thank you for your comment! Yes. I think a rangefinder would open up more possibilities. At the time the video was made, there was a small selection of small, inexpensive 50m rangefinders. Now there are quite a few products available, so maybe I'll make the next one.
Please keep me up to date if you ever do plan on selling these. I would love to see an optic with the sight of my choice. It's a small cosmetic thing, but i think it would be amazing
Awesome job! Keep it up, i think it would be better if instead of 'working...' was the range of the target or some type of information about Time/Direction. Looking forward to see more!
Thank you for your comment. I hope you like it. Yes, I should have put something more practical there. I couldn't implement it elsewhere, so I'm cheating. It seems to be very fun if you show the distance, compass, number of bullets remaining. I'm slowly developing the next version, so I hope you'll come back again. Thank you!
Oh Man. thank you so much. i am currently designing and printing a full-auto capable air rifle, which is actually completely arduino- controlled, so this idea fits so perfectly. You have no idea how many ideas you gave me just now XD i could make a HUD displaying firing mode, air pressure distance to target etc etc i could even make it compensate for drop over distance. again, thank you so much, nothing can ruin this day anymore
It works very well with my .22 single shot. Simple to adjust and right on point with elevation and windage. A great buy for any hunters or for competition.
This is so far the 3rd diy smart sight I've seen for airsoft, I think yours is personally favorite looking one though since it's got the least intrusion, Great work keep it up
Thanks for your comment. I'm glad you evaluated it. There are still many drawbacks, but I will continue to challenge the production. I hope you will visit us again. Thank you!

@@Kousaku_Japan use CR123 or their Rechargable counterpart and a usb charger board. I also recommed the Arduino 33 BLE Sense it has a 9 axis inertial sensor and bluetooth (so you can sight it in via Bluetooth and possibly save sighting data for different rifles). and lastly i recomend Elgoo's ABS like Resin its stronger and not so brittle like normal Resin

really beautiful design and execution. thanks for letting us into your process, I can't wait to see your next works. I play dartsoft and I know for a fact the community would be all over this if you made it available in the future.
Thanks for your comment. Sorry for the late reply. I'm currently developing a small sight scope. Maybe I'll post some videos about the figures two more times, but after that I'll be back at sight scope. If you want to get information faster, look for my Twitter account. It should be written in the summary section. Choose your favorite language. Thank you!
I think this is awesome! But also one thing that was totally forgotten or more likely not even known by Mr. "I have to make it" is that even the commercial optical sights are not accurate out-of-the-box. They still need to be sighted in on the range for the range you intend to shoot them at. Yes there was a drop at the target range...just like with real firearms, just a bit closer with airsoft. Real sights have windage and elevation adjustments to sight in for the rifle and ammo you are using. The fact that you not only managed to get it to work but to also hit the paper target with your first shot is incredible. I hope you have continued to work on this.
I was going through the settings on CoD warzone and insurgency for aiming down the sights and they said it follows a s-curve. You said we should use a circular curve too instead of a linear one. Can you please expand on this ? Amazing video, I tried making a RDS using an old CD case from a video on youtube ofcourse. I had little success but I can say that we have come far. If you can hold the zero on this sight (which some professional weapon sights cannot and got into controversy lol) then you have really created a master piece.
Thank you for your detailed comment. I also saw the URL you received. The sights I made haven't reached a high level at all, but I think the various sensors produce interesting effects. I'm currently developing the Mark 4 with the aim of reducing the size of the hand gun. I think it's still a long way to make a video. Thank you very much. I'm glad you wrote a long sentence.
Hello! Thanks for this project! I've planned to do the same things as well and you are totally the creator I would like to meet for making this project. I'm actually starting to build my own full custom airsoft gun with many electronic components incorporated into. The sight scope is one of them. I'm actually in Japan (Tokyo) and I can't finish everything for now but this part is a part where I got many trouble to think how to do. On my project, I plan to add telemetry, WiFi control, camera integration, sight scope like yours, bb loader intelligent (counting bbs inside the loader) and some other parts I probably forgot. Actually, I'm working on the core (the electronic inside the airsoft gun) and the rest will be done later but with what you did, I am happy to see that can be possible to make one like yours. ありがとう！
Thank you for your comment. I'm sorry for the late reply. I hope you like it. Now I’m developing a smaller size one. I will upload the video when it is completed!
Thanks for your comment! Sorry for my late reply. I'm glad you're interested. I'm developing a smaller one now. I hope you will visit us again. Thank you!
Thanks for your comment! In fact, visibility in strong sunlight is not good. Shade improves a little, but it's not perfect. I'm using an organic EL display now. Brightness is fully open. As you pointed out, I also tried increasing the LCD backlight. Then the black area became brighter and the contrast dropped. It may be improved by using a stronger DLP laser. I will do my best in my research. Thank you for your advice!
Thank you for your comments. I really enjoy the process of coming up with new features and actually implementing them. Getting feedback from different people is also a great experience. Right now, it is very difficult for me to create a product with stable quality, and I feel that I am not suited for it. If I can find a good partner, it may be commercialized someday. First of all, I will try my best to make a lot of interesting things on my channel so that a lot of people can see them! Thanks for your support. It warmed my heart very much.
@@urgamecshk please make this open source, ive been working on a system that tracks ammo in my mid-caps, right now its a display near the stock, but this is a way better display implementation.
Unfortunately it's a lot more complicated than that. As a general rule, when you put airsoft accessories on actual guns they break down really quick. All the electronics in every part has to be braced to absorb the force of the constant recoil. It's much more complicated than just making the body out of metal.
@@KappaKiller108 Get the company going with an airsoft only version, while researching for real steel. I'd buy one for my airsoft G3. When the real steel came out, I'd buy one for my Oracle.
Thanks for your comment. I yearn for DARPA. However, I haven't done anything technically amazing, so I hope I'll work harder and get more attention. I was particularly pleased with this comment. Thank you!
Old video, but if you can get a long distance laser meter and hook that up so it outputs the measured distance of the meter's pointer on the OLED display, you'll have a sight scope that instantly tells the user how far their target is. This makes this even more practical.
Thanks for your comment! Your warm comments keep me motivated. I am planning to make other kinds of sight scopes, so I hope you will visit me again if you like. Thank you.
This gave me an idea: Make a sight using an FLIR sensor in the front and this OLED display in the back, displaying both the FLIR image and the reticle. Boom, thermal sight.
Thank you for your comment! I am very happy. Mine was not a very good prototype, but I'm very proud to have creators interested in it. I make crafts in many different genres, so you may not be interested in all of them, but I hope you will continue to watch my videos. I watched your channel. And I've subscribed. You seem to have been interested in drones for quite some time. I will check it out after this. Thank you!
@@Kousaku_Japan initially i worked a lot with drones, now i want to add different kind of projects with 3d printing, cnc and programming, check out the board ttgo tdisplay i used that cause it has everything (ble, wifi, li-ion charger) and oled display may be you can use in your projects, i'll be watching your videos
Thanks for your comment. Actually, I'm making a next-generation scope with a compact size. Or was it a request to make a gun body? Please comment again when I upload the video. Also, if you haven't subscribed to my channel, I'd be happy if you could. Thank you!
A thermal sensor (for ex 8x8 pixel), connected to arduino, when it senses temperature of the body the sight color can change, (you have target enchancer sight from call of duty) :)
Thanks for your comment. That's a great idea! I was investigating the thermal sensor. However, I was only thinking about displaying images in the shape of a person. Arduino may not have enough processing power to realize this. It may be possible about change the color of the reticle. This is a great idea. Now I'm developing something smaller and less than 4 inches long. I want to complete this once, but I will develop a multifunctional site in the future. At that time, I definitely want to install a thermal sensor. Thank you!
Thanks for your comment! I am glad. In fact, it's hard to see in strong sunlight. It looks good with a sunshade, but it's a bit uncool. It seems that improvements are still needed. Thank you.
Wow, this is amazing, and still has a lot of potential. If you add a way to manually adjust the reticle to have the correct zero and save it, then you could also have a way to change zeroing on the fly (for example from 30 meters, to 50, and so on). If you have that, and also somehow manage to interface with a rangefinder, you would get a gun that always points exactly where your reticle aims (Not accounting for wind, but i doubt that is fixable) It would be literally last gen military tech.
Thanks for your comment! is that so! I just want to do what you said. At that time, there was no rangefinder for medium distances, but it seems that 50m rangefinders are on the market. The current model doesn't even have a physical button, so I'd like to gradually add features. Please visit my channel again. Thank you!
@@Kousaku_Japan There alee 60m and 100m Laser rangefinder modules on ebay. They use serial connection and are relative easy to integrate... For the buttons check osd control board for FPS drones, if you add a resistor to VDD you can read the buttons as analogue values...
Thanks for your replies! I checked the sensors for 60m and 100m. It's still a bit expensive, but I think I'll get one. I'll look into the osd control board a bit more. I'm glad I got your advice. I'm just wondering if my skills are good enough.
@@Kousaku_Japan I bet they are, what you have done is amazing already. I m happy my suggestion was useful, will be patiently waiting your next video :D
Thank you for your reply! I would be very happy if I could make something better with the advice of experts. Next time I'm planning to make a video that is not a figure!
I cannot wait to see further iterations that include more features of this airsoft gun sight. It has a very cyberpunk feel to it and would go excellent with cyberpunk cosplay.
actually due to the hop up, if you tilt your gun, the BB will curve in the direction of the tilt and drop down. This is because the backspin applied by the hop up, which is used to create lift and counteract gravity, is not entirely vertical.
Thank you for your comment! That's right. So in this video, I experimented with a very narrow and short range before the hop starts. I'd really like to add a range finder function to calculate the hop and fall points according to the distance. In that case, I guess it would fly more diagonally than I expected. It's a lot of work, but it's worth it. Thank you.
This is amazing! One odd recommend, is adding a jumper IO pin for sighting it Or displaying magazine count info by connecting the trigger contacts to the Arduino nano!
You're pretty good at crafting, it's really nice. As said before, you could sell this, just imagine the options : BB's ammo counter ( with addition of a captor ) distance display ( coupled with another device ), custom sights/color... I hope you can profit from this, talent is allways rewarded
What if: You were to add a RFID tag to every mag, then the gun could count the number of bb's left in each mag making the whole setup even more functional! Basically, assign a unique number to each mag with the RFID tag, add a RFID reader on the gun and use some memory management to know how much bb's each mag has.
Thank you for your comment! Oh... you are a genius. I'm working on the remaining number display function now. But I had to zero out the mag that were removed. RFID is inexpensive, and it's a dream come true. I have no idea how to connect the reader-writer to the Arduino. I'll see if I can find a better way. It's going to be a long time before I can make it happen. It was very stimulating. That's a great idea. You'll have to give me some more advice! Thank you!
@@Kousaku_Japan I think I should add on to that, instead of attaching the amount of bb's per mag to the RFID reader it should be stored on the RFID tag, that allows for usability between different guns instead of having the magazine tied to a single gun. And on that note, it would be preferable if the information stored is readable by everyone, so I think the information could be stored as plaintext or otherwise too. Best of luck to you! edit: fixed some grammar mistakes
@@Kousaku_Japan I think you can buy sticker tags for less than 100 yen each in aliexpress that were intended for clothes and cards, but then the reader would be the expensive one
Hey, really great video. I loved that it used many differents tinkering skills ( 3d printing, electronics, math, etc...). The only downside is I would have loved more tests in the end (more with the camera through lens, without first-person view camera so you can focus on good aiming, without a scope at all. So we can have more data to compare
Thanks for your comment. I'm sorry for my late reply. I was happy that you liked it. There was a restriction that I couldn't shoot a lot at the shooting location. Noise and safety aspects, so the number of tests wasn't enough. Now that I'm making a smaller one, I think this live-fire test will shoot more. Thank you!
You are relieved you can make it? The rest of the internet is amazed you can make it and make it work! And do not feel sorry about the length of your video. I like it 😎
for practical purposes most experienced shooters prefer 1 moa red dots because its a lot easier to hit more accurately and quickly compared to the eo tech recticle where it can block a target
This is so cool! The moving circle for tilt angle takes it to the next level. I'm trying to do a similar thing as this to make a heads up display in a snowboarding helmet. I'm struggling to learn how to program the display haha. I'll get there.
got here after the Valk cam video, awesome work, you could probably contact the people from DevTac with this idea :D they also started doing airsoft equipment
This is exactly what I have been dreaming of. Now to wait and see if you sell any for us who cant do the 3d printing or are to dumb to make it on our own
Most of the video I was thinking "I should try this." Then I saw the coding portions and all I could think was, "well... Maybe he'll end up selling them..."
Super cool. You may be able to sight it by adding an X axis screw (side to side) on the OLED and a Y axis screw (front to back) on the actual glass (or vice versa). What an awesome project.
Thank you for your comment! I think this is a great idea. The current prototype does not have the ability to adjust zero-in, but the only way I could think of to add it would be to move the front of the unit. Certainly, moving the OLED would make this possible. Thanks for the great idea. And thanks for the positive feedback on the project!
This is truly awesome,and i read some comments wich all had great ideas mine would be Making it more like an Eotech in looks so the display is inside a hull wich protects it so rain or other stuff cant mess with the scope
Hi. I actually made this, I didnt know anyone else had made one too!!, with arduino too and the same exact screen, but mine has I2C so its just 4 wires to drive the screen but didnt use a reflex sight, thats a great idea! For the gyro, I had a lot of gyro drift (did you fix it?). I end up only using the accelerometer instead. Mine is driving an HPA gun (multiple fire sequences like binary, sniper mode, single, burst, full auto, etc, I control all the BB loading times and such from the arduino too). I have ammo counter and a nice graphic that makes it look like the gun from Halo. I also added mag detection. I made a complete 3D printed gearbox with switches to detect the mag, detect full/semi/auto, and detect the trigger pulls. Mine also has 3 buttons on the screen to change settings. I am using the EEPROM to store them. I also made a custom circuit board for it. Contact me on FB. Lets share ideas :D
Thank you for your comment! A laser rangefinder capable of measuring 60 meters was still quite expensive at the time. I'd love to do it when it gets a little cheaper. I think it would add a lot of functionality. Thank you!
@@Kousaku_Japan Maybe this can help you: th-cam.com/video/FA4mfvgpOQQ/w-d-xo.html There is also a commercial solution for an arduino laser range finder, but it is a little more expensive: www.tindie.com/products/greathings/laser-rangefinder-module-v2-20hz80m/
I believe the small Arduino you used has a linear regulator. You are likely losing half (or more) of your battery power as heat. A switching regulator should improve the battery life a lot. Thanks for sharing your excellent project.
Hey! I absolutely love what you've done and would like to do it for myself! I was wondering if you could share the files with me? Also, where did you get that red dot lens?
Really awesome project! I have a suggestion: Could you position the horizontal and vertical lines around the reticle to move with the reticle so the reticle is never obstructed by the lines? Maybe also add some smoothing to the gyro inputs so the reticle is not so jittery (but still accurate for airsoft purposes) ? I would love to see a follow up !!
Thank you for your comment! I think I can change the reticle. I'm just a little worried about the speed of the drawing. The reticle behavior is with a significant amount of drift correction. I wonder if I can make it any smoother. I think the dot spacing is going to be a problem now. The more comments I get, the more I want to try different things. It's motivation for me. Thank you!
Impressed by the result, definitely would buy it. I would suggest you to build those plastic parts out of metal with lost-wax method in order to enhance the durability, and perhaps shrink the overall size a little so more things could be mounted in front of the lens such as a lens protector or another scope. I hope you could actually make a fortune from your design, you deserve it.
I’m by no means an expert, but I have years of experience with optics, reflex sights, and firearms. So here is my input, laser range finder, that displays where the shot will land, but do not move the reticle, instead show where the POI is relating to the reticle. This involves some fairly high-level mathematics to accomplish and a decent amount of computing power. It can be done though. Ammunition counter would be nice, and mil dots would be nice. Personally when it comes to reticles, I like a more simple reticle, but a complex reticle like the tremor 6 is really nice. For the ammunition counter this can be done in a few ways, a sensor in the bolt of a real firearm, that detects substantial movement. However for air soft I would actually use a visual sensor that uses light at the end of the barrel. Kinda like the ones use for tracer BB’s. I don’t know enough about airsoft to say anything there though.
You could add a laser range finder to the sight so that it can automatically adjust the correction radius for the reticle based upon the distance to the target.
Thank you for your comment!
For airsoft, I would like to measure up to about 60 meters, but those parts are still expensive. I'll take the challenge when they're less expensive.
Airsoft ballistics seem to be quite complicated to calculate because they hop and then fall. But that's why it's so interesting.
Thank you!

I don't think it's possible that no one has ever thought of this before.

Now imagine of you put it inside a long range scope and the ballistic computer even shows you the trajectory of your bullet on your display (the newest ones are already advaced as heck but I don't know if they can do that)
*"If it doesn't exist, i have to make it"* is the new *"Fine, I'll do it myself"* for me.
This is a very cool idea but you may find that it is better applied to other uses than as an optical sight for the following reason:
Parallax.
If you cannot set the parallax of the OLED screen out to 100M then the user cannot both, focus the sight, and the target together. One will be out of focus.
Most reflex optics are set to ~100M/Yds. Some are set even closer (for pistol use).
The advantage of a true Holosight is that the hologram is actually parallax free and remains perfectly in focus when you concentrate on the target at any distance. The reticle in a Holosight will remain the same size no matter where you put the sight on the rifle. The 1MOA dot in the center of a real Eotech is actually ~.33 MOA and even under a 3X magnifier will appear to be 1MOA to the human eye.
There are other design considerations to keep in mind when making a miniature aiming system.
Keep up the good work!
If someone can make the body out of milled steel and someone else can come up with an intuitive software solution to interacting with the optic’s parameters, you have a pretty good product on your hands
Steel? Nah. Aluminium, sure. 7075 is as tough as untreated mild steel. I work in R&D in the defense industry and could help you out with milling if you want @工作ジャパン Kousaku Japan
Wouldnt steel be too heavy for an optic?
@@duodotI am looking into starting my own optics brand, could you mill me some frames for red dots??!?!
If you are ready, maybe send it to some american gun channels like "Demolition Ranch" , "Jerry Michulek" or "T Rex Arms" for promotion
(And maybe a bullet counter with an accellerometer that detects recoil)
Thank you for your comment!
This sight has shrunk a bit because I couldn't get past its weakness of being difficult to use in bright light.
My current push is this one.
th-cam.com/video/qnoximEMF68/w-d-xo.html
It's not practical, but I think it has impact. What do you think?
you could also add a reticle tuning trough software ... rendering circle lower or uppre, more left or right ;-)
Thank you for your comment. It's a reticle adjustment function! I couldn't do it because I didn't have the technology to insert a physical button. Certainly adjustment function is necessary! I would like to include the next work.
Thank you.
The channel master is a very, very gentlemanly man.
He's also very skilled and amazing. This is the kind of channel that should grow.
amazing im kinda lost for words...these are perfect..once they are structurally sound they may just be the worlds number 1 airsoft sight
This is incredible and has so much potential even for real steel applications
This is crazy! Just the mere idea of gyroscopic red dot sight is already mind-blowing! 🔥⚡
This has such a Ghost Recon vibe. Love it
Edit, if there was ever a Ghost Recon VR game, i hope this would be a feature
Very fine craftsmanship. It takes both skill and practicality to make something like this
Don't be sorry for the long video, I was hooked the whole time! You came up with something really cool!
this, auto rangefinder adjustment, and customizable reticle and youd have something you really could sell to a lot of people.
Thank you for your comment!
Yes. I think a rangefinder would open up more possibilities.
At the time the video was made, there was a small selection of small, inexpensive 50m rangefinders. Now there are quite a few products available, so maybe I'll make the next one.
@@Kousaku_Japan im excited to see your next video on this!
Think of a calibration of some sort, either digital or screws to adjust POI. Nice work
Thanks for your comment. Certainly there was no adjustment mechanism. I will try to implement it in the next version. Thank you very much!
I think the adjustment could be done with software. Use a couple buttons for up/down etc..
Japan has always made great optics, don't know how well this works but this one does look fun
Please keep me up to date if you ever do plan on selling these. I would love to see an optic with the sight of my choice. It's a small cosmetic thing, but i think it would be amazing
It's awesome how it evolves so much from mark 1 to mark 2
Thank you for your comment!
I’m very happy with the warm comments.
It was very motivating.
Thank you!
Awesome job! Keep it up, i think it would be better if instead of 'working...' was the range of the target or some type of information about Time/Direction. Looking forward to see more!
Thank you for your comment. I hope you like it.
Yes, I should have put something more practical there.
I couldn't implement it elsewhere, so I'm cheating.
It seems to be very fun if you show the distance, compass, number of bullets remaining.
I'm slowly developing the next version, so I hope you'll come back again.
Thank you!
Oh Man. thank you so much. i am currently designing and printing a full-auto capable air rifle, which is actually completely arduino- controlled, so this idea fits so perfectly. You have no idea how many ideas you gave me just now XD i could make a HUD displaying firing mode, air pressure distance to target etc etc i could even make it compensate for drop over distance. again, thank you so much, nothing can ruin this day anymore
This is a awesome video! Great job and the tilt function is amazing! I wish I could make one for myself.
Thanks for your comment. I'm glad to praise you for the tilt function. Thank you!
It works very well with my .22 single shot. Simple to adjust and right on point with elevation and windage. A great buy for any hunters or for competition.
This is really cool man. Keep it up!!!
Thanks for your comment! I'm very happy. I am looking forward to seeing you again.

Awesome!
Thanks for watching. There are other videos of Fall Guys and Valkyrie camera of R6S, so please watch them if you like!
Thank you.
This is so far the 3rd diy smart sight I've seen for airsoft, I think yours is personally favorite looking one though since it's got the least intrusion, Great work keep it up
Thanks for your comment.
I'm glad you evaluated it.
There are still many drawbacks, but I will continue to challenge the production.
I hope you will visit us again. Thank you!
maybe make the battery housing below the sight and built-in mounting to rail?
Thanks for your comment.
I'm pretty worried about the battery. I'm trying to make it a little smaller and shorter. The goal is to place it in front of the lens.
I hope you will visit us again. Thank you.
@@Kousaku_Japan use CR123 or their Rechargable counterpart and a usb charger board. I also recommed the Arduino 33 BLE Sense it has a 9 axis inertial sensor and bluetooth (so you can sight it in via Bluetooth and possibly save sighting data for different rifles). and lastly i recomend Elgoo's ABS like Resin its stronger and not so brittle like normal Resin
you sir, you are a genius, that thing is so cool. you could make tons of money with your holosight and that thing. i want a normal holosight now... :D

I'm currently developing a small sight scope. Maybe I'll post some videos about the figures two more times, but after that I'll be back at sight scope.
If you want to get information faster, look for my Twitter account. It should be written in the summary section. Choose your favorite language. Thank you!
I think this is awesome! But also one thing that was totally forgotten or more likely not even known by Mr. "I have to make it" is that even the commercial optical sights are not accurate out-of-the-box. They still need to be sighted in on the range for the range you intend to shoot them at. Yes there was a drop at the target range...just like with real firearms, just a bit closer with airsoft. Real sights have windage and elevation adjustments to sight in for the rifle and ammo you are using. The fact that you not only managed to get it to work but to also hit the paper target with your first shot is incredible. I hope you have continued to work on this.
Whoa! Now this is awesome!
Thanks for your comment! I hope you enjoy it and you will visit us again.
I got motivated! Thank you!
never did i think i needed something like this, but dear lord i want it so badly.
I was going through the settings on CoD warzone and insurgency for aiming down the sights and they said it follows a s-curve. You said we should use a circular curve too instead of a linear one. Can you please expand on this ? Amazing video, I tried making a RDS using an old CD case from a video on youtube ofcourse. I had little success but I can say that we have come far. If you can hold the zero on this sight (which some professional weapon sights cannot and got into controversy lol) then you have really created a master piece.
th-cam.com/video/57PNhV5iHyM/w-d-xo.html
Thank you for your detailed comment. I also saw the URL you received. The sights I made haven't reached a high level at all, but I think the various sensors produce interesting effects.
I'm currently developing the Mark 4 with the aim of reducing the size of the hand gun. I think it's still a long way to make a video.
Thank you very much. I'm glad you wrote a long sentence.
Hello! Thanks for this project! I've planned to do the same things as well and you are totally the creator I would like to meet for making this project. I'm actually starting to build my own full custom airsoft gun with many electronic components incorporated into. The sight scope is one of them. I'm actually in Japan (Tokyo) and I can't finish everything for now but this part is a part where I got many trouble to think how to do.
On my project, I plan to add telemetry, WiFi control, camera integration, sight scope like yours, bb loader intelligent (counting bbs inside the loader) and some other parts I probably forgot. Actually, I'm working on the core (the electronic inside the airsoft gun) and the rest will be done later but with what you did, I am happy to see that can be possible to make one like yours.
ありがとう！
That's some amazing work
Thank you for your comment. I'm sorry for the late reply. I hope you like it.

The start of something very beautiful. Kousaku Japan thank you!
This is super cool!. How is it on daylight? I think you could make it much more bright if you use an LCD screen and put a powerfull led behind.
Thanks for your comment!
In fact, visibility in strong sunlight is not good. Shade improves a little, but it's not perfect.
I'm using an organic EL display now. Brightness is fully open. As you pointed out, I also tried increasing the LCD backlight.
Then the black area became brighter and the contrast dropped. It may be improved by using a stronger DLP laser. I will do my best in my research.
Thank you for your advice!
Even if you sold these as kits to be assembled by the buyer, as long as you did the coding portion, I'd be in. Holy cow, this is EPIC.
If you continue to refine it you could sell this, I would be your first customer.
Thank you for your comments.
I really enjoy the process of coming up with new features and actually implementing them. Getting feedback from different people is also a great experience.
Right now, it is very difficult for me to create a product with stable quality, and I feel that I am not suited for it.
If I can find a good partner, it may be commercialized someday. First of all, I will try my best to make a lot of interesting things on my channel so that a lot of people can see them!
Thanks for your support. It warmed my heart very much.
@@Kousaku_Japan can you make the code open source, and allow people like me to machine and make them?
@@urgamecshk please make this open source, ive been working on a system that tracks ammo in my mid-caps, right now its a display near the stock, but this is a way better display implementation.
Absolutely incredible work. The tilt adjustment of the reticle is very clever!

I am very happy with the warm comments.
It was very motivating.
Thank you!
Okay, but like if you mass produced it and made it out of metal, you could make a HUGE profit
Hell, I'd buy one!
Unfortunately it's a lot more complicated than that.
As a general rule, when you put airsoft accessories on actual guns they break down really quick. All the electronics in every part has to be braced to absorb the force of the constant recoil. It's much more complicated than just making the body out of metal.

I was particularly pleased with this comment. Thank you!
Old video, but if you can get a long distance laser meter and hook that up so it outputs the measured distance of the meter's pointer on the OLED display, you'll have a sight scope that instantly tells the user how far their target is. This makes this even more practical.
very nice job!
Thanks for your comment!
Your warm comments keep me motivated.
I am planning to make other kinds of sight scopes, so I hope you will visit me again if you like.

This gave me an idea: Make a sight using an FLIR sensor in the front and this OLED display in the back, displaying both the FLIR image and the reticle. Boom, thermal sight.
Great project!

@@Kousaku_Japan it is a request to make a gun body
A thermal sensor (for ex 8x8 pixel), connected to arduino, when it senses temperature of the body the sight color can change, (you have target enchancer sight from call of duty) :)
Thanks for your comment.
That's a great idea!
I was investigating the thermal sensor. However, I was only thinking about displaying images in the shape of a person. Arduino may not have enough processing power to realize this.
It may be possible about change the color of the reticle. This is a great idea.
Now I'm developing something smaller and less than 4 inches long. I want to complete this once, but I will develop a multifunctional site in the future. At that time, I definitely want to install a thermal sensor.
Thank you!
How does this preform under daylight. It looks super cool
Thanks for your comment! I am glad.
In fact, it's hard to see in strong sunlight. It looks good with a sunshade, but it's a bit uncool.
It seems that improvements are still needed. Thank you.
Man, that resin takes paint so well.
🤘
Thanks for your comment🙏
We are currently developing a more compact model.
Wow, this is amazing, and still has a lot of potential.
If you add a way to manually adjust the reticle to have the correct zero and save it, then you could also have a way to change zeroing on the fly (for example from 30 meters, to 50, and so on).
If you have that, and also somehow manage to interface with a rangefinder, you would get a gun that always points exactly where your reticle aims (Not accounting for wind, but i doubt that is fixable)
It would be literally last gen military tech.
Thanks for your comment! is that so! I just want to do what you said.
At that time, there was no rangefinder for medium distances, but it seems that 50m rangefinders are on the market.
The current model doesn't even have a physical button, so I'd like to gradually add features.
Please visit my channel again. Thank you!
@@Kousaku_Japan
There alee 60m and 100m Laser rangefinder modules on ebay. They use serial connection and are relative easy to integrate...
For the buttons check osd control board for FPS drones, if you add a resistor to VDD you can read the buttons as analogue values...
Thanks for your replies!
I checked the sensors for 60m and 100m. It's still a bit expensive, but I think I'll get one.
I'll look into the osd control board a bit more.
I'm glad I got your advice.

Legend says of a man who became a millionaire by selling cool scopes to America and likes every comment.
honestly this is the best project and presintation i have ever seen.
I cannot wait to see further iterations that include more features of this airsoft gun sight. It has a very cyberpunk feel to it and would go excellent with cyberpunk cosplay.
my respect just went over 1000 when I saw this.
if u can easily customize it like in COD videogames... thats gold fr
actually due to the hop up, if you tilt your gun, the BB will curve in the direction of the tilt and drop down. This is because the backspin applied by the hop up, which is used to create lift and counteract gravity, is not entirely vertical.
Thank you for your comment!
That's right. So in this video, I experimented with a very narrow and short range before the hop starts.
I'd really like to add a range finder function to calculate the hop and fall points according to the distance.
In that case, I guess it would fly more diagonally than I expected. It's a lot of work, but it's worth it.
Thank you.
Many people will love this kind of gimmick accessories, you should try to sell them 😘😘😘
This is amazing! One odd recommend, is adding a jumper IO pin for sighting it Or displaying magazine count info by connecting the trigger contacts to the Arduino nano!
You're pretty good at crafting, it's really nice. As said before, you could sell this, just imagine the options : BB's ammo counter ( with addition of a captor ) distance display ( coupled with another device ), custom sights/color... I hope you can profit from this, talent is allways rewarded
My man work for Ghost in the shell/Cyberpunk gun company right now !!
Somethig like this for actual use could be very cool, adapting sensors to display stuff, even just a round counter would be very cool
What if: You were to add a RFID tag to every mag, then the gun could count the number of bb's left in each mag making the whole setup even more functional! Basically, assign a unique number to each mag with the RFID tag, add a RFID reader on the gun and use some memory management to know how much bb's each mag has.
Thank you for your comment!
Oh... you are a genius.
I'm working on the remaining number display function now. But I had to zero out the mag that were removed.
RFID is inexpensive, and it's a dream come true.
I have no idea how to connect the reader-writer to the Arduino. I'll see if I can find a better way. It's going to be a long time before I can make it happen.
It was very stimulating. That's a great idea. You'll have to give me some more advice!
Thank you!
@@Kousaku_Japan I think I should add on to that, instead of attaching the amount of bb's per mag to the RFID reader it should be stored on the RFID tag, that allows for usability between different guns instead of having the magazine tied to a single gun. And on that note, it would be preferable if the information stored is readable by everyone, so I think the information could be stored as plaintext or otherwise too. Best of luck to you!
edit: fixed some grammar mistakes
@@Kousaku_Japan I think you can buy sticker tags for less than 100 yen each in aliexpress that were intended for clothes and cards, but then the reader would be the expensive one
Hey, really great video. I loved that it used many differents tinkering skills ( 3d printing, electronics, math, etc...). The only downside is I would have loved more tests in the end (more with the camera through lens, without first-person view camera so you can focus on good aiming, without a scope at all. So we can have more data to compare
Thanks for your comment. I'm sorry for my late reply. I was happy that you liked it.
There was a restriction that I couldn't shoot a lot at the shooting location. Noise and safety aspects, so the number of tests wasn't enough.
Now that I'm making a smaller one, I think this live-fire test will shoot more. Thank you!
You are relieved you can make it? The rest of the internet is amazed you can make it and make it work!
And do not feel sorry about the length of your video. I like it 😎
Bro this is crazy. Amazing job. Keep up the incredible work.
Really cool invention! Can't wait to see how you improve it and add new stuff, or build completely new ones! Great channel
I'm really proud of your work!
for practical purposes most experienced shooters prefer 1 moa red dots because its a lot easier to hit more accurately and quickly compared to the eo tech recticle where it can block a target
it looks amazing. very professionally.
This is so cool! The moving circle for tilt angle takes it to the next level. I'm trying to do a similar thing as this to make a heads up display in a snowboarding helmet. I'm struggling to learn how to program the display haha. I'll get there.
got here after the Valk cam video, awesome work, you could probably contact the people from DevTac with this idea :D they also started doing airsoft equipment
This is beautiful.
I am in such awe.
Great job.
This is exactly what I have been dreaming of. Now to wait and see if you sell any for us who cant do the 3d printing or are to dumb to make it on our own
Most of the video I was thinking "I should try this." Then I saw the coding portions and all I could think was, "well... Maybe he'll end up selling them..."
Super cool. You may be able to sight it by adding an X axis screw (side to side) on the OLED and a Y axis screw (front to back) on the actual glass (or vice versa). What an awesome project.
Thank you for your comment!
I think this is a great idea. The current prototype does not have the ability to adjust zero-in, but the only way I could think of to add it would be to move the front of the unit.
Certainly, moving the OLED would make this possible. Thanks for the great idea. And thanks for the positive feedback on the project!
This is truly awesome,and i read some comments wich all had great ideas mine would be
Making it more like an Eotech in looks so the display is inside a hull wich protects it so rain or other stuff cant mess with the scope
Hi.
I actually made this, I didnt know anyone else had made one too!!, with arduino too and the same exact screen, but mine has I2C so its just 4 wires to drive the screen but didnt use a reflex sight, thats a great idea! For the gyro, I had a lot of gyro drift (did you fix it?). I end up only using the accelerometer instead.
Mine is driving an HPA gun (multiple fire sequences like binary, sniper mode, single, burst, full auto, etc, I control all the BB loading times and such from the arduino too). I have ammo counter and a nice graphic that makes it look like the gun from Halo. I also added mag detection. I made a complete 3D printed gearbox with switches to detect the mag, detect full/semi/auto, and detect the trigger pulls. Mine also has 3 buttons on the screen to change settings. I am using the EEPROM to store them. I also made a custom circuit board for it.
Contact me on FB. Lets share ideas :D
With a laser range finder and some simple ballistics data, this scope would be perfect!
Thank you for your comment!
A laser rangefinder capable of measuring 60 meters was still quite expensive at the time. I'd love to do it when it gets a little cheaper.
I think it would add a lot of functionality.
Thank you!
@@Kousaku_Japan Maybe this can help you: th-cam.com/video/FA4mfvgpOQQ/w-d-xo.html
There is also a commercial solution for an arduino laser range finder, but it is a little more expensive: www.tindie.com/products/greathings/laser-rangefinder-module-v2-20hz80m/
Beautifully done. Ichiban!
I believe the small Arduino you used has a linear regulator. You are likely losing half (or more) of your battery power as heat. A switching regulator should improve the battery life a lot.
Thanks for sharing your excellent project.
On a scope you could display distances on the screen, and a button to toggle between yards (the dot would adjust location based upon target distance)
Thank you for creating this masterpiece, now I can aim with M231 in phantom forces
Hey! I absolutely love what you've done and would like to do it for myself! I was wondering if you could share the files with me? Also, where did you get that red dot lens?
now imagine somehow connecting that scope to your trigger so it detects when its pressed and shows how many rounds you have left
Really awesome project! I have a suggestion: Could you position the horizontal and vertical lines around the reticle to move with the reticle so the reticle is never obstructed by the lines? Maybe also add some smoothing to the gyro inputs so the reticle is not so jittery (but still accurate for airsoft purposes) ?
I would love to see a follow up !!
Thank you for your comment!
I think I can change the reticle. I'm just a little worried about the speed of the drawing.
The reticle behavior is with a significant amount of drift correction.
I wonder if I can make it any smoother. I think the dot spacing is going to be a problem now.
The more comments I get, the more I want to try different things. It's motivation for me.
Thank you!
Impressed by the result, definitely would buy it. I would suggest you to build those plastic parts out of metal with lost-wax method in order to enhance the durability, and perhaps shrink the overall size a little so more things could be mounted in front of the lens such as a lens protector or another scope. I hope you could actually make a fortune from your design, you deserve it.
I’m by no means an expert, but I have years of experience with optics, reflex sights, and firearms. So here is my input, laser range finder, that displays where the shot will land, but do not move the reticle, instead show where the POI is relating to the reticle. This involves some fairly high-level mathematics to accomplish and a decent amount of computing power. It can be done though. Ammunition counter would be nice, and mil dots would be nice. Personally when it comes to reticles, I like a more simple reticle, but a complex reticle like the tremor 6 is really nice. For the ammunition counter this can be done in a few ways, a sensor in the bolt of a real firearm, that detects substantial movement. However for air soft I would actually use a visual sensor that uses light at the end of the barrel. Kinda like the ones use for tracer BB’s. I don’t know enough about airsoft to say anything there though.
