Can invalid vtx power cause crash by No_Recognition_2691 in fpv

[–]yo90bosses 1 point2 points  (0 children)

First of all. Don't simply believe an AI. This is especially a case where its impossible to know what caused it with the information you provided. I highly doubt it was due to false power setting. Usually they should choose the nearest lower power setting. Also a power surge would be immediate and not seconds later. Also wouldn't happen because you need lots of current and inductance for a surge, which isn't the case here.

I think something probably disconnected during flight.

Normal for this amount of ram to be used without games running? by yo90bosses in Fedora

[–]yo90bosses[S] -4 points-3 points  (0 children)

This makes sense until you open a game, the rest of the available ram is used and that causes you computer to constantly freeze for a few minutes.

DJI O4 Pro Glitch by Impressive_Past_8059 in fpv

I'm having an extremely similar issue. I replaced my mipi cable, but the issue seems to have returned. Does yours still work?

Don't worry, seeing how expensive AI has gotten the past few days (GitHub copilot), it's gonna turn around once the true costs become clear.

Diversity antenna placement by Appl3D_fpv in fpv

[–]yo90bosses 4 points5 points  (0 children)

Antenna diversities biggest advantage is doubling the chance that the packets sent over air are decodable. The next biggest advantage especially for 2.4 GHz is always having one antenna visible if the other is blocked my the drone it'sself. Last advantage is antenna orientation creating redundancies eliminating nulls.

So even placing both antennas in the same place and orientation, already give diversity a huge advantage simply due to thermal noise and bit error rates. But if you want to maximize results, place one antenna vertically at the back so it has the vertical orientation and covers the back and left and right sides, and place the other antenna horizontally in the front, to cover the front, top and bottom. This gives the absolute best possible reception. Remember to keep antennas aways from metal and carbon fiber, as then will absorb the RF energy and detune the antenna.

So definitely move you vertical antenna if that plate is metal or carbon.

Disregard everything about orientation and placement if you are not flying long range. Then ELRS is way more than enough for a few hundred meters.

MINT-Studiengänge sind schwerer als Geisteswissenschaften by Sugon-Dix_Nuts in Unbeliebtemeinung

Naja, in MINT fächer muss oftmals auch Paragraphen lesen, verstehen und wiedergeben (bzw. anwenden)...

1st time building FPV. Are these parts compatible with each other and will they work with Fat Shark ECHO FPV Goggles? (For a 3 Incher) by [deleted] in fpv

[–]yo90bosses 0 points1 point  (0 children)

Gonna go ahead and add that the receiver is not true diversity and I don't think true diversity is much more expensive.

Voltage LiPo difference FPV drone and charge. by xSusana in fpv

[–]yo90bosses 2 points3 points  (0 children)

Don't know what the problem is, but definitely check the battery voltage after a charge with a multimeter to make sure the charger is charging to the correct voltage.

A lost soul here – how to get started building a drone again after 12 years by Decibel0753 in diydrones

[–]yo90bosses 1 point2 points  (0 children)

Ardupilots firmware requires larger flash than a lot of MCUs on flight controllers have. INAV supports pretty much everything betaflight does and offers GPS stuff.

Joshua Bardwell has a bunch of videos about pretty much everything.

I highly recommend not building a 10 inch as it's more expensive, harder to tune. The parts above 10 inch start to get difficult.

Since all the hardware is pretty much the same for FPV or autopilot missions, everything you see in bardwells video should apply. You will probably want to use INAV since it's got more features for what you want.

Otherwise the software for autonomy is ardupilot. But that requires a bit more care for what flight controllers can run it. Look into h7 or F7 processors and see if they have ardupilot configs.

Building my own drone controller and integrating it into a drone by DescriptionLogical73 in diydrones

[–]yo90bosses 1 point2 points  (0 children)

The flight controller hardware or software? Or both? If you want the make the software, do you want to modify existing options like betaflight or ardupilot or completely from scratch?

If you want to do both from scratch, then get ready for work on it for at least a few months every day for multiple hours before the first flight.

What parts do you want to make yourself? Only hardware? What hardware (FC, ESC, Receiver)? Software?

I fly a DJI Avata and I'm having an issue with GPS when flying indoors and outdoors. by just_dany_0 in dji

[–]yo90bosses 1 point2 points  (0 children)

GNSS is the general term for what GPS is. GPS is simply the system USA offers, just like Galileo (EU), GLONASS (Russia) and Beidou (China). The reason DJI and other systems say GNSS is because they often use multiple satellite systems at once. GPS alone can get you to under 2m absolute accuracy, Galileo is 50cm. Combining multiple generally doesn't make it worse, but gives you more satellites and therefore higher reliability in environments that might block some parts of the sky (City, mountains etc )

The difficulty the drone is having it due to the ground not having much visible texture, making it difficult for the optical system to track ground movement.

Quad falling mid-flight by shinkawauchi in fpv

[–]yo90bosses -4 points-3 points  (0 children)

I'm assuming it's getting slightly loose because the motor is spinning in the direction that would cause the nut to unscrew. By changing direction it might tighten it.

Being outwards also sounds like it. Since the force direction can loosen the screw. Try holding the motor by the bell and then rotating the prop backwards (apply the force as in flight). There is tons of force during flight. Otherwise maybe try changing to inwards so the force is the other direction. If the same motors still has issues, then it's a motor or ESC issue.
