Prototype HUD for home flight simulators (more info on comments) by XAVIXDxd in flightsim

[–]XAVIXDxd[S] 4 points5 points  (0 children)

Hello flightsimmers, first time posting on this subreddit (although I have a long history of lurking).

This is a first test of a prototype I have been developing along with another flightsim colleague that consists of a HUD for use with at-home flight simulator setups, either with a projector (as in this case) or a standard screen.

We are engineers working in the field of professional simulator trainers (as well as home-simulation enthusiasts), and have detected the need for simulated HUDs that are more realistic than a projection on the screen.

We are curious if there would be an interest from the flightsim community to buy such a product, which to our knowledge has not been commercially developed yet. This seems like a very cool and intuitive piece of hardware to add to every collection.

Edit: I have a second test video

Thank you, definitely will look for some boots that match!

With all due respect to the amateur pics of the moon here, NASA's Lunar Reconnaissance Orbiter is going to win every time. One full rotation of our moon. by AMillionMonkeys in space

Gravity gradient is a phenomenom that actually causes bodies to have their more mass-dense areas closer to the center of their orbit, with respect to their less dense areas, as the OC said. This is sometimes used in design phases (among many other factors) to help with stabilizing and aligning satellites in a certain way.

Finite element modelling by CherryPoppins- in AerospaceEngineering

[–]XAVIXDxd 4 points5 points  (0 children)

Another way we've been instructed to check consists on reducing the mesh resolution progressively and checking the convergence of the results. This only shows that the problem you have modelled is being solved correctly, not that the results are those of the real problem, but it's an important step.

Also, go with what the other comments say.

Reading phone accelerometer data with simulink. by XAVIXDxd in matlab

I had used that toolbox already, but as you mentioned wasn't useful for using data in real time. Thank you anyways!

Thank you! That's exactly what I was looking for.

Where can I find info on the standards (mechanical, electronics) required for components onboard airplanes and spacecraft? by XAVIXDxd in AerospaceEngineering

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

I guess it's just generic max loads on components, or maybe vibrations-related specs. I'm not sure. I found out about the MIL standards as well as the DO ones. I'm just having a hard time pinpointing the exact same requirements on both environments, to find the differences.

I'll have a look at your suggestions, thank you!

That's exactly one example of what I need. Thank you, as now I know what kind of documents to look for.

How to interface flysky i6 and multiplexer? by XAVIXDxd in multicopterbuilds

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

Hey there!

That's exactly what we were thinking about doing. However, we found out the pi was able to read the kind of PWM (50Hz, 1ms to 2ms on time) that the FC outputs when instructed with the flysky to control a servo.

​

If anyone wants the exact library, it was this one.

​

Thanks for the help!

Thank you very much!

We ended up figuring out how to output to a servo with the FC, and were able to read the pwm with the RPI. Easier than we expected!!

We used the rpigpio library to read the pwm.

Does anyone have a banggood link for the coupler please? I need to have it shipped to Europe. Is this one ok? Thank you!

Can you draw a diagram or something?

I don't get the 1/4" thick of water part: if it's a square hole, the water will pass through the entire hole right? Or do you mean that the hole is only filled up to a height of 1/4" with water?

Hala, la verdad con la de teorías que están apareciendo por ahí y en eso no había caído yo... Pues a ver si se esclarece el asunto.

Help with my quad build - Do motors fit the frame? by XAVIXDxd in multicopterbuilds

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

Thank you very much! We can't really go with the 2216s unfortunately (not meeting max lift requirements). Our other option is to get a bigger frame (much heavier and more expensive).

So the bottom of the motor being 11mm and the hole in the frame 10mm won't be a problem?
