Simply adjust the Fusion 360 file to fit your tank. By default it's designed to fit on my tank's 13mm rim. Make sure the bottom will fit on your tank. I have not printed or tested the SG90 parts. The SM22 STLs definitely fit together, since they are the ones I have used. Both contain the Fusion 360 files if you want/need to modify any of the parts.

zip folder contains two sets of STL files, one for the original SM22 servo motor that I used and another for the far more common SG90 servo. You're not going to get far without them.The. So, if you use flakes like me I highly recommend you grind them up to the point where they will all fit into the wheel in any orientation, and pay special attention to this if you're planning on leaving the tank unattended for a long period of time (like, more than a week), a clogged hopper will prevent your fish from being fed! In theory, any solid food should work, and I have found that unground flakes will clog the hopper.
#Diy automatic fish feeder code
If the amount of food coming out is not enough, simply copy/paste the feeding code in the arduino to dump a second or third portion into the tank.Īs for the type of food, I've only tested it with ground-up fish flakes. The feeding mechanism is the same for all three tiers, so if the amount of food it meters out is too much for your tank, I've provided the CAD files from Fusion 360 for you to edit, simply reduce the size of the pocket in the feeder wheel to reduce the amount of food coming out. I have a betta and 5 neon tetras in a 13 gallon tank, one feeding cycle puts enough food into the tank for all of them. Use this if you're on a tight budget or, like me, you can't get Tier 2 working before you leave for a week and a half for the holidays.
For those reasons, I don’t use an automatic fish feeder.Tier 1 is the most basic feeder. Also, I have no problem not feeding my fish every day while I’m out town. Due to my picky eaters, I, or my tank sitter, have to feed my fish frozen food by hand.
#Diy automatic fish feeder full
If you’re lucky to have a tank full of fish that will all eat flaked and pelleted food, then the automatic fish feeder can be a saving grace for you. Just make sure you give your sitter the “Don’t kill the fish” worksheet found in my Pre-Travel Planning and Preparation Guide so they are familiar with your system! You’ll still need to rely on a tank sitter which isn’t a bad thing as they can look over the system while they are there feeding. For example, if you know some of your fish will eat flaked/pelleted food, then your sitter could come every two days versus every day. I won’t deny that if some of your fish are getting fed, then that is better than no fish getting any food. An automatic fish feeder can be used to bridge the days when your tank sitter doesn’t feed. These fish will need to be fed another type of food (probably frozen food) which has to be done by hand. If these fish won’t eat what comes out of the automatic feeder, then these fish aren’t getting fed, rendering the automatic feeder partly useless. I’ve also kept several types of anthias that refuse flaked and pelleted food. My Banggai cardinal fish ( Pterapogon kauderni) and White Tail Bristletooth Tang ( Ctenochaetus flavicauda) flat out refuse flaked and pelleted food. Third, not every fish will eat flaked or pelleted food. The automatic fish feeders that are on the market only dispense flaked or pelleted food, which brings up drawback #3 Second, at this time there is not a commercially available (i.e., not D.I.Y.) automatic fish feeder that feeds frozen food. If you’re gone for an extended period time and are relying on an automatic fish feeder that fails, then your fish either go hungry or you’ll come home to a nutrient issue and/or algae outbreak. When they fail, they either don’t dispense food, or they dispense way too much food.
The drawbacks to an automatic fish feeder are three fold:įirst, automatic fish feeders can fail. This automated feeding is beneficial for when you are away from your tank for several days or if you like to feed your fish several times a day and can’t or don’t want to feed by hand. The automatic fish feeder dispenses food and your fish should get fed (more on the should part in a bit).
The biggest benefit to an automatic fish feeder is that you don’t have to be present to feed your fish. While you likely enjoy feeding your fish manually, there are merits and drawbacks to using an automatic fish feeder. Your finned friends simply cannot survive without being fed something.
