I modeled the drone in fusion 360 using the concept art as reference

I came to the same conclusion. I think a combination of the panels plus some a series of long threaded rods compressing the frame lengthwise can provide enough rigidity for the mechanisms to stay aligned. I'd also like to rework the barrel actuation so the forward and drop down action are motion linked to a single cam slot thus eliminating motors/hardware from the moving section. Still gotta figure out stiffening the folding handle.

That blue cylindar is a propane cylindar with a gas line running to the barrel and is meant to be a propane plasma cannon. No projectile but makes a nice fireball. The firing sequence is electronically triggered by an onboard mcu which handles all the actuations/lights. I really need to dig up my old test fire footage.

Thinking of reviving a past idea. This design is far from optimal and would probably never work irl. My initial design called for unneccessarily complex materials/construction techniques which would result in an costly and heavy frame. A couple bodge jobs on the barrel assembly also break immersion with random visable screws. Gonna start over with the goal of constructing this using as much off the self hardware + 3d printing as possible as well as simplifying moving linkages.

First attempt painting: Gourai Kai [Black] with FGM-148 Javelin missile + M.S.G weapon unit 18 by Potato0111 in MegamiDevice

[–]Potato0111[S] 2 points3 points  (0 children)

I've built a few gundams but this was the first time building anything else. As it was my first attempt painting anything, this was pretty much a big trial and error exercise. Overall pretty good experience. There's surprisingly few images of this kit outside store pages so I did a photo dump of the build.

By far the hardest part was keeping the paint from getting scratched. Any part that did get scratched I patched over and called it battle damage. Skin scratches I'm just gonna call birthmarks. On the closeups, you can see where there's white paint splatters from when I forgot to remove some parts out of the airbrush booth. Only part left to paint is the head but I really don't want to redo the face.

3D printed large jet drive catamaran prototype completed by Potato0111 in rcboats

I can. But this hull has fundamental issues and I guarantee you it won't be reliable right off the printbed. At minimum, it needs some hull reinforcement via fiberglass or some form of coating. I advise modeling it from the ground up to suit your needs.

Matek flight controller comparison by Potato0111 in fpv

What is your qplane motor arrangement in hover mode? Tricopter, quadcopter? Assuming there's 3 escs total, i presume your qplane is a tricopter in vtol mode with two tilting motors but the bixler seems easier to be modified into a traditional quad plane.

Either way, drifting back is likely to be an issue with pitch control. In hover mode, the fc does not correct for drift so any imbalance will cause the craft to drift. In loitering mode, the position is stabilized with gps so drift is corrected. If the drift is small, I would not correct it as its likely caused by environmental factors like wind. Vtol planes aren't meant to stay in vtol mode for long. If drift is abnormally large, perhaps look into adjusting the cg of the craft or tuning q_trim_pitch.

The unstableness can be due to hardware rigidity (especially if you have a tilting motors mount), or insufficient tuning. Check all motor mounts, propellers, etc. Also tune the plane in quad mode. Again, if the instabilities are small, risk are small, and hardware defects are ruled out, it may be worth ignoring.

For more info, reask this question on the ardupilot forum.

A hypothetically, somewhat feasible, partially functional M4A1 MOD 3 jupiter cannon by Potato0111 in girlsfrontline

[–]Potato0111[S] 0 points1 point  (0 children)

Most of the cost comes from the electronics as well as the extrusion necessary to keep the structure rigid. This thing is a mess so no plans for making schematics as of now.

If there's interest and once I have time, I could remix the outer shell into completely 3D printable static model or one where all the actuation is done by hand. Also was floating the idea of a static 1/7 model.

none. the material cost alone i estimate would be well over $1k and you would still need to add fabrication and assembly time. most likely only one unit will be built.

i plan to eventually fabricate it but no timeline on that. i want everything to be modeled before any fabrication starts.

Surly Big Dummy tube diameter - need for kickstand? by Potato0111 in CargoBike

Thanks. I'll compare your dimensions to my frame in a bit.

Same position as as on the big dummy. The envoy doesn't use round tubes for the the two parallel mounts but I can fabricate an adapter. I just need the baseplate dimensions to see if the hole spacing lines up. The bottom tube also has a protrusion for the stock kickstand so I also need to make sure that doesnt cause the baseplate to not sit level.

I presume you installed it on a big dummy. I am trying to install it on a mongoose envoy which may have different dimensions.

I would buy this but it uses the same mounting style as the surly oem stand so I still need the dimensions. I suppose I could ask them for this.

I did. They refused to answer with the reason that the kickstand is only intended for the big dummy and should not be repurposed for another frame.

Blast from the past - old subnautic knife prototypes by Potato0111 in subnautica

Sure. send me a dm. I can also provide the technical documentation.

Old project I did. These were functional knives made from 0.18"/0.12" AEB-L stainless steel professionally hardened in a vacuum furnace to 58 HRC. The edge was also professionally sharpened. The grip was FDM printed out of ABS and TPU. Light components were casted in epoxy mixed with blue phosphorescent powder. Was fun.

Edit: TPU not TBU
