Fun project for pet owners. Great presentation!
Glad to see you here, Devin!
Awesome video. Thank you for the files and instructions.
I am so excited to try and make this. Thanks for the work
Nice parameterized CAD files. I don't have a cat, but would totally make this for them if I went on vacation.
Wow. This is fantastic.
It's free now, you can download and print one :)
Amazing! Thanks for sharing
Thank you very much! Great video!
Nice job!
Cool. Printing now. I've added a laser range finder for the hopper, a load cell to set the portions by weight, and an RTC with a battery backup. I'll update you with how it works.
Thanks for the purchase!
Yeah, I forgot the RTC in the scheme but there's some code for it in the description (the library I used is universal).
I'd be glad to see your results. Also I'm curious about the load cell.
Sounds great. Have you managed to finish it?
@@yusufkus1 I quess he is still making it
Nice work!!
I absolutely loved this! I am going to make it this month!! :D

This is awesome
Thank you so much! This video is very helpful for me.
This is sick
Wow. Cool
this project is so well thought out. Love the design. #fatpetfeeder
Good job
We are super impressed with the details and thought you put into this. We've been trying to design a 3D printed auto feeder for my rabbits, and this is so much better - we will be setting it up as soon as we can get all the parts together. Ignore the dislikes - there are some people who just do that to be annoying - and keep doing what you are doing. I will teach my husband what patreon is now :-)
Oh, also, what printer do you use? It looks like it has a very large print bed
@@rhmontg1 Thanks, really happy to hear that! It's Prusa mk3, it's 25*21cm print bed, pretty typical for most of the printers. There's a smaller version in the pack, I use it for my cat.
Im happy to finally find your video on this sea! Thank you so much!
I bought a petsafe smart feed in february this year. which is very similar to the format of your project.
I live in germany and i asked my brother to install it in a opendoors (but covered) space in a small farm in brazil.
I have three cats living in that farm. All I ask my brother to do is to fill the petsafe compartment with food every 9 days.
After all these months using it, my cats bring attention to this equipment and other cats started appearing in the area.
I can follow everything that happens there by a camera.
I programmed food to be delivered 2 times a day. The three of my cats follow a line. There is no fight. Everything goes smooth. Once one finish, other assume the dish, until the last one.
The problem is that this place is open. There are no fences. One of the invasor cats started to appear when my cats are there eating. This invader sometimes just ignore who is on the dish and just go there and start eating. It is really annoying. The invasor do not respect nothing.
I started to think how is possible to close the dish by remote control when such an invasor appear. Maybe a lid that closes the dish when I see the invasor is around. Then I just close the lid until the invasor learns that this dish was not designed for him and just leave my three cats in peace.
Hope you can help me to think on how to do something.
Thank you so much for your project. It inspires a lot.
I dont know what servo to use. I know a little bit about how to control it using raspberry.
Please let me know if you can give me some drives on how to proceed to implement a lid on the dish.
🤞🏼✨😺😺😺
Hi! Thank you for your warm words. I don't think its a good question in the context of this video, it's a separate issue. Basically, yes, you either create a new device with the new requirements for it. Or you add a cover+small servo to the existing device as a hack. You can use mg995/996 servo for this purpose or even something smaller like sg90. Choose your way and just pursuit. It's not hard to code and these servos have a driver inside, no need for complex logic, RPI + 5-6v power supply is enough to work with it.
5:15 if you want to make your switches have less throw you can remove the metal arms off the microswitches and move them closer, or add a spacer for upgrading existing prints. Cool project!
It's already the case here.
@@MomWillBeProud Oh, whoops, I only noticed the large throw and that the arms were on in the beginning. 😅
I guess the next option would be to move the switch actuator further away from the hinge point of the flappy button. 🙂
@@b5a5m5 it works fine when assembled, I don't see an issue here.
Hi there, thanks so much for an awesome project. I am trying to adjust the FeederInside part to fit a slightly smaller servo 40.5x19.8mm - I'm still a F365 newbie and wondered if there's an easy way to do this (e.g. editing a parameter)? Much appreciated!
Sure, you can edit the numbers on a MotorStand sketch and maybe on an extrude action for the height.
Though these numbers are very close to the ones used (41.4x20.5 minus 0.4 gap) and I'd recommend just keep it as is, it's not supposed to fit there tight. It's kept from falling out by the top part.
I am going to attempt to make this
Excellent Work!!!!
Thanks. It's free now, go get one :)
@@MomWillBeProud Gee that is amazing !!!
I want to know if this 3D printed model parts will fit in for the fully automatic feeder as well, which u had shown in your other video. The second one made with cans
Chahal Kailashiya Sure they will. It's only the code that is different. The code is also provided
Wow. I don´t even have a cat but damn thats meowsome! :D
Subbed 0/ crazy stuff man!
Hi there, thank you for the design and tutorial. We built the DC circuit version so far and everything seems to work. We don't know what the buttons do exactly in the default program but we do see the motor move, could you let us know? and does it feed automatically with the default code in your link or does that take some extra work on our part? if the default code includes automatic feeding how often does it feed and how does it know when to start?
Hi! The buttons change the portion size (the time that the servo turns, movement just indicates that the feeder understood the command) and the middle one is just to force dispense food once.
fpf12h.ino serves food once every 12 hours, first serving is done immediately after plugging into the socket.
I finally printed everything and have some follow questions about the program. If I adjust the portion sizes up or down does that get stored? If I unplug the power does the portion size I last set it to stay or does it go back to default?
@@Adoula7 the example program doesn't have any persistence but you can implement it yourself. It's probably like 10 lines of code, it's a good programming practice.
I have a dog with a electronic pet collar. I'd like to detect his collar and prevent him from stealing the cat food from this feeder. What kind of sensor do I need to detect his collar?
I don't know exactly the technology used in your dog collar. I suspect that it's an RFID tag there. You can use RFID reader/writer module like MFRC522 but you probably have to make your own antenna to work with it because it's made to work within 1cm range.
Cool project! I saw the RTC isn`t included into the sketch, is there an update available where did you included it?
Yeah, I forgot it. See in the description.
@@HungrysitesRu oh I found the sketch on the git revisions. 👌🏼
Does not the food get stuck there between wheel and compartment? Like the pieces of food stuck between?
Some dust does but it doesn't affect the function. I took this seriously designing this thing.
Hi! This is a fantastic build thank you! Is there a way to do this build with PVC pipes instead of 3D printing the materials? Also is there a possibility of making this solar powered?
Hi. Sure, you can reinvent the project from scratch and it will be a completely new project. I have no intention to do that, sorry.
I'm looking to make this or your earlier DIY cat feeder with two cans or some hybrid of both? Using one of my ESP32 modules. I'd like to power it via solar-charging USB powerbank for my yard, and triggered via motion sensors. I might have a lot of questions... :)
Nice, go for it! The previous is definitely simpler but this one looks like a real household appliance. Both work really well.
Hi there! awesome design! Why did you choose for a hopper system? instead of a belt, or a screw driven transport system. was it more reliable? or just better looking ;)
belt is harder to manufacture DIY-style but I think it's the best option because it cannot jam if you dispense from the top of the feeder. Also you can use any bowl at the bottom.
I don't think there's a big difference between screw and the wheel. Screw eats horizontal space, wheel eats the vertical one. There should be a hopper anyways if you want to use all the food you put into it. Even if you use a belt.
Also probably a cheap stepper would be better than a continuous servo to make it more precise.
You really explained it well❤️ what if we use spiral conveyor shaft to dispense food instead of that rotary blades. Also did your food become humid?
I don't remember why I decided not to use an auger, probably it used more space. You definitely can try to use it but it basically means to rebuild the entire project from scratch.
It didn't become humid though I don't live in a humid place, it could be an issue elsewhere.
Hello, I wanted to attempt this project and I'm putting together the list of parts into my cart. I'm new to fiddling with electronics, so what exact wires are you using? There's male to female and other variations. I'm not sure which one I'm supposed to use. Don't want to use the wrong wire and make something explode!
Hi!
You can even solder them in, it doesn't really matter, you just need the correct endpoints to be connected. If you want a modular prototype then I'd recommend bying all three types - f-f, m-f, m-m, if you're going to try other projects, these will help a lot. The absolute minimum is 3 wires male to female to connect the board to the servo. As for the buttons, there are no pins so you have to solder/twist the wires there. You can use the same male to female and strip one end to be soldered to the button. Though the feeder can be functional with only a servo+arduino.
may i mnow or can you teach me how to code for set time feeding process instead of pushing buttons?
Love it! but how did you teach your cat to operate this feeder? ;)
Not worth it. Just use a timer-based code.
Hey, nice project. Just to be clear, the LM2587, IRL540N, capacitor, etc are necessary only for the battery version? If I want to use the power supply, I will need only the arduino and servo. Is that right?
Yes, that's right
@@MomWillBeProud Just one more question to effectively buy the license. Do you know if anyone has managed to 3d-print on Ender 3 with success?

Hey, I'm pretty sure my mom is proud of me now: ua-cam.com/video/aF1oW6MEi0k/v-deo.html
By the way, I could 3d print using ender 3 with no problems. Thanks!
Great design. I would like to use with a NEMA 17 stepper motor, is that possible? Also, my cat eats four times a day. I would like to slowly reduce his intake as he is a fat cat. Can additional daily feeding times be added easily? Thank you for a great project very well documented.
Feel free to modify any way you want, the code and the model are available for free.
I can provide no additional support though.
1. What 3D printer do you have?
2. Can this be modified for rabbit pellets and portion control for them?
1. Prusa i3 mk3s
2. Probably. I haven't owned rabbits but for hamsters I would be concerned about them eating the plastic away to get to the food.
For long pellets it would probably require to increase the gap above the feeding wheel, that means you would have to move the hopper upwards and the shell would be too high for my printer to print in one piece. I wouldn't recommend lowering the hopper height because then it would be too shallow angle to print.
I don't have time make my own diy, where can i buy something like this? Please 🙏 I need this for my cats
There are not supporter during printing. Can it be? I don't have much experience 3D printing, please advice me!
The design was specifically made to be printed without supports, yes.
did you think to use arduino nano to connect to wifi and send command via computer or phone to feed a cat?
I mentioned it in the video. I don't need it and I'm probably not going to make it. But it's definitely possible and go for it.
@@MomWillBeProud can you set up limit for feeding? i.e. /if button pressed and time is less than 3 hours, no food/ ? i think you will need time lock RTC for this, i guess.
@@falconych Arduino contains a microcontroller. You can program anything you can imagine into it. It's not that hard if you try.
In my case there's 10 minutes limit 2 feedings, 24 hours limit 6 feedings.
RTC isn't necessary to track time because Arduino can handle that well enough on its own (if the power delivery is consistent). But for the battery version I recommend it because Arduino isn't that good in tracking time during the deep sleep. It has to be in a deep sleep to save battery (2 months vs 2 years battery life).
What's the different function between 3 microswitches in this cat feeder sirr?(based on your program)
More, less, dispense now. But it's really up to you.
Is there a way of making this pc compatible where it is somehow connected to the pc and have it work via a software or by clicking a keyboard keybind?
Sure, arduino can talk to a computer through USB interface but you have to write a few lines of code for that.
that's pretty cool. I don't have a 3D printer, is there one you recommend to print large sizes like this?
Hi. Depending on your budget it's always Creality Ender 3 (current version v2) or Prusa Mk3 (current version S+) for the last 3 years.

Hello ! A big thanks for your project/video ! Now i have a small question : is it possible to power this using the usb port on the arduino instead of the DC connector? I think i saw somewhere that it is also 5V. Thnaks again :)
You can definitely do that but this servo can stall up to 2.5 amps at 7V, that's quite a lot for most of the USB ports and chargers. I tested 2 amp apple charger, it works, but 1 amp charges sometimes don't.
Also if you use arduino internal 12->5V converter, it's rated 5V 0.8 amps, that is even lower. So you have to use big capacitors or take the risk of something not working or even being damaged.
@@HungrysitesRu ok so better use the DC connector then 😅 thanks , i'm new to electronics !
Hey can u pls help me i wanna do your arduino cat feeder but idk how to add a light to it can u pls help me
I own rabbits. I leave them in cages for many reasons. So I'm trying to come u with a simple system to make an automatic feeder to feed all of them depending on the size of the rabbit. Any help would be very appreciated. Thank you so much!
Very cool project! #FatPetFeeder
It's free now, you can download and print one :)
This looks great! Was jamming ever a problem in the designing process? Any measures to overcome it? #FatPetFeeder
It was fully redesigned several times because of jamming issues with the previous versions. In this version - no jams ever.
1. Gap high enough to let food get through
2. Blades are rotated so there's no point when the entire blade is against the hopper corner
3. Blades have a triangular profile so the last part that is against the hopper corner is much lower than the first one so it has more space for food to get through
4. Software has two forward one back nature so even if something gets stuck it will release in the next cycle. I.e. 500ms forward,100ms back, 300ms forward, 100ms back for one feeding.
Also there are parameters for the blades height and the gap height so it's pretty easy to change.
You get one. Contact me, email is in my profile. Don't forget to mention your UA-cam account name.
Can I replace the continuous rotation servo with a strong DC motor? I don't know where in the breadboard to plug the DC in, so I hope you can possibly help me. You don't have to spend a lot of time (cuz life span is limited) because this is a simple task!
And I bought the STL files. Great job on modeling those ones!
파루_UA-cam you can. Basically the "continuous rotation servo" is not a servo, it's a DC motor with an embedded driver. But if you want to use standalone DC motor then you have to 1. change the model to fit your specific DC motor, 2. use an external driver or MOSFET to connect it to arduino because the current of arduino is not enough and you will burn your microcontroller if you don't use MOSFET. 3. you will have to significantly change the code because it's written for the servo.
So if you don't want to spend days of making all these changes or don't have the qualification then I'd strongly recommend using the servo, it's only 10usd to buy one.
I definitely can help to find an error in your code or recommend the ways you can change the model to accomodate the motor but I can't spend hours doing this. If at some point you feel that's not enough please message me on cubebrush in the next several days so I could refund your purchase before it's too late according to their TOS.
Regards!
@@HungrysitesRu What a caring answer! But one thing: I live in Korea and it will take me forever to buy it with amazon and in Korea, there aren't so many servos to choose from. Thx for answering!

Are these any better in terms of delivery? I'm sure you can find similar "continuous servo" locally, you just need to match the dimensions ~~40*20*40mm, you don't need this specific model.
Oh, btw, you will need something like an H-bridge, not just a MOSFET if you want it to turn both ways (jiggle to make sure the cat food isn's stuck there).

Hi sir , I bought the files , but want to cancel the button and make it by schedule, and how to add WiFi camera on it
#cat_feeder
Hi man! gist.github.com/ulitiy/25d675591af73f347926b7a4e6921797 this code feeds every 8 hours but you can tweak it.
As for the camera I don't have such a demand and there are so many device options so you have to find out on your own, you have the source.
WiFi camera can be independent or you can make a raspberry pi with a camera and the code running on it but it's not arduino-compatible.
Please ask if you have any specific issues, obviously I can't rewrite the code for each user needs but I can give you a hint on how to solve a thing that you're stuck on.
hi, i was about to start printing it and i realised you didn't post the electronics compartment without the battery part. I don't want to put some batteries because im remixing it a bit, you have the files or do i have to edit it by myself?
Hi. There are no files without battery, I decided not to support this version.
@@HungrysitesRu okay thank you for the great work on the model!
Hi this is exactly what I have been looking for. I went ahead and purchased your files to make this myself. Would it be okay if I made a video out of it? I haven’t posted in a while but would like to go back to making videos. I have a small (really small) channel but I still thought it would ask.
Sure, just follow the fair use rule if you're using parts of this video.
Mom Will Be Proud • DIY channel awesome thanks. I don’t think I will use any part of your video but I’ll make sure to mention you and provide a link to your video. Thanks!
thank you so much for this project.
i would like to adapt the code so i could set specific times of the day to trigger the feeder.
has anybody here already tried this?
Thank you. There's a code example with 8 hours delay though it's not made to use with a battery. The code for a battery version should be different (using timer/RTC pin interrupts).
Is this better than your previous one made with pringles box?
Previous one is cheaper and better keeps flavour.
This one looks much better, it's sturdier and more convenient to clean, transport, add more food. Also this one doesn't need a power brick but this feature you can also add to the previous one. The portion size is much more consistent.
Both work well, just a matter of personal preferences and priorities. If you want something cheaper or don't have a 3D printer - the first one is fine.
Another question, what’s the default size of the feeder. I am asking if my printer is big enough to print the model

This is a great project. Quick question. Whenever I change a parameter in Fusion 360 in the model I get loads of errors. Is it working for anyone else?
Maybe the design was too complex, maybe the implementation has too many dependencies. Yeah, basically you have to fix them all. It's pretty hard so I think it's better not to change or limit yourself only to changing some specific parts like bowl diameter.

I don't remember exactly, I think it's about $30 with cheap PLA and Arduino clones
@@HungrysitesRu oh wow! That’s pretty good! Thank you for the quick reply!
Amazing channel, by the way 👏🏾
How big is your 3D printer
210*250*210
Can you make it using live camera and talking to the pet
I'm not planning making these changes but it's definitely possible.
Please make it. That will be useful to many students or pet owners
which is the maximum size of the dry food?
Pellet size up to 10mm should be ok but you can increase the height of the feeder wheel so it can take larger ones and not lock up.
@@MomWillBeProud in the video what are de dimentions of your feeder? Which printer do you use ?
13*21*21cm for the small version, 18*21*21 for the big one (the largest part)
Net internal volume is 1-2L
Prusa i3 mk3s
@@MomWillBeProud I have ender 3 pro, I wandering what are the maximum volume for the food. Or if can I print aditional part , like an expansión for more volumen for food
@@oscarserrano7717 maximum I think is 1.5L, it will fit into your printer (the volume is limited by the construction of the hopper, I really tried to make it bigger). You can easily make an extension on top. Or if you don't want to model, just print a second shell part and glue it to the bottom one so the volume will be up to 9L
That fritzing diagram seems to be missing the RTC, but should be easy enough to figure it out
Yes, you're the first one who caught me! :D
You can take the pin numbers from the code.
@@MomWillBeProud Thanks. I don't quite understand the use of the MOSFET. Is that so the boost converter only triggers when the servo is called to run? How are you powering the arduino off just three D-cells? Doesn't the arduino require at least 5V?
1. MOSFET cuts the current to boost and servo. It saves a lot of battery life.
2. I use arduino at 8MHz (burn the respective bootloader) and 3V is enough. It can also work even at 1.8V@4MHz.
3. If you want to save even more battery you need to cut the leads to the internal linear converter. Otherwise it will drain in weeks.
@@MomWillBeProud Can you explain the linear converter cutting? Thx.

how much feed it give one time?
It's a DIY project, you can program it yourself according to your needs.
Thanks
Would you sell one of these pet feeders?
No, I only the 3d model
I loved it, please do help me for the arduino code for my pet feeder with innovation of notifer. Please do reply. Thank you!
Please be specific, what do you need help with? I can't spend hours writing code for you but I can spend 5 minutes finding an error in your code.
Mom Will Be Proud • DIY channel Iam having hard time to program my dog feeder which is Iam using Arduino Uno and with real time clock for timer, a servo motor, a sim900a for the notifier and a keypad membrane switch. Can you help me to program all this three to work.
Mom Will Be Proud • DIY channel because the mechanics of the dog feeder is, it is set to a exact time to fed the dog, and it will trigger the servi to opperate and afterward the device will notify the owner of the dog feeder that his or her dog is already been fed.
@@babymachoasic5832 please reread my previous message. You can't just ask people to donate their hours of life to do the job for you. Life span is limited. You haven't even provided any code.
Mom Will Be Proud • DIY channel because the thing is I have codes but seperately each module.

Nice project. Want one for my pet.
It's free now, go get one :)
Hey, Alexander.
I tried to contact you in the Cubebrush site for more information, but no success. Do you have an contact mail address? thanks.
Hm I put together the battery version and it does not works. :/.
Well I guess it's a part of any learning experience. You'll figure it out.
@@MomWillBeProud Thank you fopr the fast answer. I am really noob in this kind of stuff. I used LM2596 DC-DC Step-Down instead of urs, maybe thats the problem? also I use uno.
@@Zuluparaszt3 try running it with usb power maybe just to check
открывай ИП и начинай продавать!
Nice project I have 2 dogs but only one of them is Fat :D #FatPetFeeder
You get one. Contact me, email is in my profile. Don't forget to mention your UA-cam account name.
Subscribe and hit the like button. this is awesome project, i hope can make this one for my cat #FatPetFeeder
What if you don't have a 3d printer
You can buy one of find another feeder on this channel
