I am building a Ornithopter. or mostly trying out a wing design to see if i can get any lift not really trying for flight just working the flapping part.

Wow it’s been awhille…
well someone got funing 400$ yay. anyway someone forgot about there tolerances. and the main gear is really wobbly oh well lets see what i can do here a quick vid for u guys.
Hi Java!
Approved! :D Great work - I see that you got rid of the filament from the BOM and adjusted the funding request. All other aspects of this look great! :)
Hello!
We don't typically fund filament just like that - Instead, can you remove the filament from your request and we will reimburse you for the filament that you use?
Hey! This is a really cool project, but I have a few things before we can approve.
First, we don't pay for RC remotes. You will have to pay for the remote yourself.
Second, we don't pay for 3D printer nozzles! You will have to pay for that yourself aswell.
Third, I want to make it very clear - this project can only be submitted for fundingg once. I see that you are in stage 1 of 4 of this project - you can not get an additional grant for any of the future stages from any hack club program. One grant per project. So, if you want funding for the rest of it, design it now!
Otherwise this looks good and I really appreciate the animations.
Hi! Please upload your CAD files as .STEP files, not as a .zip file and upload a .f3z file or add an Onshape link so we can see the progress of your CAD over time. Additionally, please add a custom and in-depth wiring diagram, the one you currently have looks like it was taken from a manufacturer's website. Thanks!
Hello, and what an amazing project to make! However, you need to include the schematic wiring that is going to be making your Ornithopter, along with the firmware (if needed) for the project.
the CAD is super impressive! however you can save a ton of funding by sourcing everything from aliexpress. if the original model isn't there, you should still be able to find a viable alternative. otherwise, looking good!

So as I wait for grant money, I have decided to make a fork of the project in Onshape, and I made it smaller. I now have an 80 tooth on the big main gear instead of a 112 tooth. I am still going to be making the 112 tooth version, as I would like to get my first prototype made. This will let me practice building, and I can tweak anything else in the next version.

I am thinking of moving this dev log to my new website.
I ask in the slack if I could move the dev logs to my website I made for the project. so I may be just putting links to them here. aka I think I am going a little crazy whille I wait for funding apps to reopen anyway here are some photos of what I may added to the website.

Hello Been awhile. What I have done.
Here a cool video of it

Hello Yall, maybe I should lock in to what I am making give some more
detail of how this project is going to work out.
So I am trying to make a ornithopter what it does is it flap its wing to
generate life ( aka a mechinal bird) The Goal of the project: to build a
lightweight ornithopter capable of stable powered flight using a simple
flapping mechanism.
The project will be set up in phases.
Phase 1
This is the prototyping phase of the wing movement mechanism. I will be
designing a body that takes the rotating motion from a motor to move the
wings up and down. I will be looking for reliability, strength, and
efficiency.
Phase 2
Here I will be designing the wing. I need to make it lightweight. I will
also be testing it with the gear mechanism and measuring how much lift
it produces so I can determine my design constraints for the tail.
Phase 3 – Adding the Tail and Other Electronics
This is where I will be adding the tail and electronics together. I will
also be doing some early test flights if all goes to plan. My goal is
to have a clean mechanical system. The tail will look like an airplane
tail, as I am currently just focusing on the flapping mechanism.
Phase 4
This phase is for debugging and testing. I want to aim for reliability
and simplicity, and I will be conducting my own test flights as well.
Current Progress (Phase 1)
I am currently in Phase 1 and have decided to use a crankshaft based
mechanism for wing motion.I am using this simulation tool to help
calculate and visualize the wing
path:https://www.desmos.com/calculator/iuprdl6sxkMy motor has a KV
rating of 1700, and I will need a gear reduction of approximately
21.24:1. This may change during testing, but for now I am satisfied with
the I have just submitted my project for funding so I am hoping it will
go though.
– Changes I’ve Made.
So I change how the space sits as it look a little to week and it was
interfering with the flapping motion

So I’ve Finish my design and I would be ready to move to the protyping phase. from the last design i have change the movment mech so that I have a clean path to follow. I also made a bom list of all of the parts.

Hello, this is my Ornithopter project. I am just working on a mechanism to move the wings up and down. This will let me test to see if I have the flapping motion correct. The next thing I need to do is print it out and do a test with it to see if my measurements are right.In Onshape right now, I need to get the ratio proper so I can have a clean up-and-down movement.The next thing I need to do is prototype with a 3D printer.
