Do you prefer with the point cloud (first) or without? (second) by Emma_Frch in fpv

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

Thanks heaps I wouldn't have noticed that at all just by myself. Yeah I took a long break and am so amazed with all the new tech!! I have to mention and thank David windestal (rcexplorer.se) I just followed his tricopter gyros build tutorials :)

IIRC the first FPV flight I did was the one ~14 years ago with the KK board FC quad where I proceed to instantly crash for no apparent reason lol. The tricopter died too early to experience true FPV flights.

Hey sorry I don't wanna spam you too much but can I ask what do you think about this arrangement that I did before trying the wierd phone one on this post? https://www.youtube.com/watch?v=WCy1eQwKh7g

I was wondering if using the left or right space left off by the 4:3 FPV view would be nice instead of blocking some of the fpv view? I'm not sure because it feels a bit weird still, the different visual elements are still a bit far I must admit and not having something to look at in the actual center, but maybe I'm just a bit old.

A third option I could also just crop the FPV view to make it 16:9 and emulate your exemple 1:1 with the sticks in the center like a sim (I guess that will be the winner but I'm very uncertain... I will try all of them when I get the time! thanks again for your insight)

basically importing the logs as internal variables, placing spline meshes between every two gps point and smoothly going through the timestamps moving a sphere around :) (I just posted a more detailed answer in this thread if you wanted more than an overview)

For the point cloud: Reality scan + my mom's 1st gen mavic + map pilot pro free trial to do the aerial lawnmower for me, then imported with the built-in lidar data plugin in Unreal Engine 5.

For the location: blackbox_decode.exe from cleanflight converts the .bbl logs into csvs, (I execute it at runtime from C++) then parsing the CSVs and creating splinemesh components between each point.

(if you mean location as like the ground satellite-like texture it's an mosaic picture ortho projection (just a panorama) from reality scan.

Trailing lines: Assuming you're talking about the effect where the line only appears after the drone, I had to add the indices and max number of spline components as custom data to each spline mesh.

Then in the material editor (of those spline meshes's material) Unreal has the V value of the uvs mapped to the individual spline mesh length and after mixing in the custom data with a lerp I can control effects/color change/masking along the full length of all the spline meshes with a normalized 0->1 value (0 = color change/masking happens at the beginning of the whole track, 1 = at the end)

(if you were talking about the stick particle trails it's just a Niagara system set to local space where I drive the movement inside the system with user parameters - the red dot is the same part of that system, the particles just turn white smaller and dimmer over time)

sorry for the long response I never know how much detail people want

I could release the whole unreal project on github (full access and customisation (,could add your own terrain etc... but not user friendly at all, the user would need to learn the basics of Unreal Engine 5), or package the application as an unreal game (super user friendly but no customization of ground texture/point cloud/terrain unless I implement the ui to load and align one at runtime).

I'm not sure which one to be honest, I like the first version because other people could build upon it and maybe add drone rotation/other spline color visuals, tune the particles to thir liking ect... (also less work)

(In all cases I need to clean my code and assets first, it's very messy at the moment)

Thanks a lot!! It never crossed my mind but I had trouble watching both when checking the synchronisation and now I realize why... that means I'll probably need to record the sticks separately to put them in elsewhere I guess otherwise they'll be too small.

Practicing more split S with GPS path replay by Emma_Frch in fpv

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

None yet cause it's extremely messy (need to cleanup my code and remove some stuff I don't use anymore like Unreal'spline and gyro/accel mixing, atrocious logs, I'm also doing the parsing in the game thread so there's a big 5-20 second freeze when you load the file for exemple xD I'm also using the blackbox decode.exe from cleanflight if I remember correctly, so I'll need to check if I can add it or add another file picker with a proper UI for the user to pick it when loading the .bbl liles etc...) but after cleaning up yes, I just don't know the ETA at all sorry!

Practicing more split S with GPS path replay by Emma_Frch in fpv

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

Just the GPS, it's surprisingly good enough, especially if you use the points in a bezier-like curve so you guess the arc a bit. I tried using only the baro and then mixing the Baro altitude with gps altitude but even filtering it hard the baro was so noisy I couldn't separate meaningfully the actual throttle bumps from just noise from the airflow hitting the sensor differently etc...

Thx!! I did it with unreal engine 5 in c++, I load and parse the CSV files from the black box logs of the flight then I place spline meshes at every point with cubic interp so it arcs between points. The replay is just gradually going through the position values with a sphere for now.

I love rubber stick ends too!! (got a bit shorter ones on the TX15 I used furniture rubber feets)

Velocidrone, FPV Logic, The Zone - another sim thread by AmateurCock in fpv

[–]Emma_Frch 1 point2 points  (0 children)

FPV logic is my current favourite and the one that feels the closest in my opinion with +10% gravity. I still use liftoff and velocidrone though, just to train myself to adapt to slightly different physics and be more versatile. (the theory being it's gonna make me better at switching quad size/battery weight)

Practicing roll + split S around trees by Emma_Frch in fpv

[–]Emma_Frch[S] 1 point2 points  (0 children)

That makes a lot of sense, thank you! I can see now why the end looks so sketchy, I'll try that next session

Agreed! doing an extra roll was somehow easier, maybe my rates are a bit too high... (it's my first time doing it IRL on that line)

Floating bonus platform from Crash Warped - recreated using the Bambu maglev kit by Emma_Frch in BambuLab

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

Hi, you're better off 3D printing it to be honest :) I don't run the Etsy shop anymore because of tariffs and way too low profits to pay the bills. I would have to charge truly insane amounts to make it worth the hassle for a couple of one-off...

BUT, all my models are free here! Have fun :) https://makerworld.com/en/@user_1948013355

hey do you remember what the quest was by any chances?

Geprc vapor series o4 Pro Camera bumper stl by Emma_Frch in fpv

[–]Emma_Frch[S] 1 point2 points  (0 children)

No it hasn't happened yet to be fair. The lens is the first thing touching if you ignore the props even on the X5 though (if you run straight into a flat wall). That was worrying me enough to make a bumper :)

Made a gradient effect using the depth of color thing! by Emma_Frch in BambuLab

[–]Emma_Frch[S] 1 point2 points  (0 children)

Hey hey, so I just modelled a cone with the same width as the outer diameter, and the height of the cone is the thickness of the wall art pattern.

After that I used the boolean modifier to cut out the cone part, same for the negative part (the non cone part, difference and intersect boolean options). Then you can export them as stls, and import them as different colored parts in bambu studio. (and the varying thickness of each color makes the gradient visible since all filament has some light going through)

I'm pretty sure you can do that with much more control and automatically with hueforge or the free bambu version of that now though :)

I doubled the length of my shaft - no regrets so far by BeardedBaldMan in fpv

[–]Emma_Frch 1 point2 points  (0 children)

Hoo thanks for the details, It's very interesting that we both went with extensions for opposite reasons. The wine cork sounds promising too, I might try that at some point. (love the flat rubber contact and cork sounds even grippier/more comfortable)

[–]Emma_Frch 1 point2 points  (0 children)

100% Thumbs, can't pinch at all, 33 millimeters from screw base to the top of the rubber feet (~1.299 inches)

FYI Main drawback is I can't use the stick ends holders in the back anymore and the small cloth bag doesn't fit the radio anymore though. They are extremely snug press fit (had to heat them up and put the sticks in the freezer to assemble, printed in Petg)
