- Here's an animatronic eye mechanism I made using machining tools like a lathe, as well as 3D printing and arduino. Although I'm sure a lot of you guys don't have acess to a lathe, I hope you'll still enjoy watching the build process!

Electronics:
Arduino Uno: amzn.to/38PuH3p (or anything that can accept three analogue signals, one digital and communicate through SDA/SCL ports)
Adafruit PCA9685 16-Channel Servo Driver: amzn.to/36MSsro
5V Power Supply, around 4A is more than enough. Here is mine (tiny.cc/is4cdz)
A female DC power jack to match your power supply, to be soldered to the servo driver board
2-axis Joystick: amzn.to/2Pt7uN2
Potentiometer (optional): amzn.to/2YUyU1g
Push-to-make switch (Some joysticks have this built in, but its easier to control when its seperate: amzn.to/38Q26Lp)
10k Resistor: amzn.to/2EpS1XB
Jumper cables: amzn.to/2szkIPd
6* S05NF servos: www.sparkfun.com/products/14760
Hobby Components:
4* M2 Servo Ball-links: amzn.to/2M6Pg1Q
2* 2mm Pushrod Connector Linkages: amzn.to/2M3brpy (Not strictly necessary, you could use 2 ball links instead)
Machining Stuff - Check the schematics in the machining step to see all the components which need machining, it also has a rough guide to the lengths of stock you could start with. You might want some margin for errors, but roughly speaking you'll need:
140mm of 3mm diameter brass rod (plus an additional 100mm if you want to try bending the 3mm brass to make the x-axis pushrod - I'd recommend you don't as its very difficult to do accurately)
50mm of 5mm diameter brass rod
170mm of 4mm diameter aluminium rod
120mm of 3mm diameter aluminium rod
100mm of 2mm brass rod (or a bike spoke as I did!) if not making the 3mm x-axis pushrodDownloads:

U have no idea how note worthy such projects really are. 20 year olds do this with available material and easy readily info via. free wifi, but in the 90's this would be the cream of the crop of the advancements of humanity, and the kids jaws would drop in awe as they watched a team of 1,000 experts try to explain in understandable English kind of how it works in a class. lol
Awesome work! Currently stocking up on parts to make the compact version of your eye mechanism. Really enjoy your projects!
Really enjoying seeing the updates on these. Still haven’t finished mine yet (university and stuff getting in the way), but it's just so satisfying watching everything come together. Keep up the awesome work!
Incredible work ! Lot of technics for a magical result.
another great vid! Just love it
Very nice job! Thanks for sharing.
I love these eye mechanism vids so much!
I would love to try printing the some of machined parts with a resin printer using one of the tough resins. Great project!
Excellent job
well done fella
If you are going to machine more linkages like at 6:00, look into slitting saw blades. I've used them before, even the Dremel-sized versions will make quick work of cutting slots in brass and plastic. I just found your channel, neat projects!
Amazing as allways! If you do come back to the eyes, a pair of eyebrows could be a cool addition🤔
You have been knocking it out of the park with these Will! Please do not let up! Happy to be a patron to help keep these coming!
Very nice. Keep doing.
Another great eye mech. I have a Lathe and Milling machine but I think I will make the Advanced Mech first.
Thank you sooo much for making some pointers on the eyes and the parameters you use for printing. Ps do you have a link for the mini blots and taps you use. I am not finding 1.5mm easily. Way to help out your viewers. I think you did an awesome job on this video with your explanations and everything. Thank you again. For the extra help.
Arrgh! Now you got my mind wanting to do a strange project LOL
I see a potential for a creepy (yet eerily wonderful) take on the Cat eye clock. You know the one, that the pendulum makes the cat's eyes go side to side and tail.
I'd love to see somehow a head (human or otherwise--I was thinking of the "Greenman") with random moving and watching eyes hanging on the wall.
Now how to make this idea into a clock may be a strange matter in itself.
Anyway, thanks for putting this odd idea into my brain. I think programming the random eye movements will be the hardest part, as you have wonderfully made the mechanism work so naturally.
Where can I find the video for the 3D printed snap piece for inside the eye? Also love your videos
Do you paint them? Nice work
Это выглядит так просто. Но сколько времени уходит на разработку такого проекта?
When you burn the tip of your finger, try to remember to grab the loose skin of your earlobe (with the freshly burned finger). This will "suck out" some of the heat from you finger into your earlobe, which will lessen the severity of the burn. I learned this from a blacksmith, and use it often when soldering stuff.
Do you think there a way to put it into a cosplay head and using drone camera and a skinny vr head set ?
Where can I get that cut mat!?
Which software use for making 3d design..
How much did it cost to make this?
Wow
°o°
do you sale parts?
Где заказать такие глаза ?
WOW WOW WOW WOW WOW WOW WOW WOW WOW WOW WOW WOW
There no signin option in websites
The vise you use is old school, probably made 50 years ago
You seem to have included sources for everything except the .stl files???
You're right, sorry about that, the last link in the description to the blog post has a download link.
@@WillCogley Thanks!
why don't you try to make a design similar to this but instead have a camera in it so that you could have it for a animatronics thing that tracks faces or something like that. cool video though
These are awesome, but for something EXTREMELY attention capturing, you should make them huge. Beach ball sized! And team up with someone (JAMES BRUTON) to make them follow people around!
i think he's prototyping with aims at humanoid robotics not toys like james the useless toy maker bruton
Great work! I am just wondering why all these designs are based on both eyelids having to move the same way. Real humans mainly use the *top eyelid* to cover the whole eye and thus this lid goes beyond halfway the eye. The bottom eyelid hardly ever moves, except when squinting. The result of this design is so unnatural and will never give realistic human-like results. Dolls for kids also have only one eye lid.
What strikes me too is that the use of servo's is crude: To move the eye, the Arduino seems to send only one pulse command to move the eye to the desired position. Why not vary the pulse width in about 5 or more steps such that accelleration from the beginning position and de-accelleration near the end position occurs, resulting in much smoother movements. Or is that not possible?
I am planning to make my own animatronic eye (at half the size using 2.5g servos) and will experiment with servo command strings with varying pulse widths.
good point
stl?
Why is this not cable driven like your hand???
I agree that would be easier why does he forget that tactic all the sudden?
Жутко, но прикольно!
This helping me maybe in future i Will Made five night at grudy,😃
Do you ever reply back to messages Will, emailed you even face book pm you too but to no avail mate, please check all messages and contact me if possible, thank you Tracy B
