Looking for what's around that next hill, down that trail, up that track.

I'm adding aerial shots to videos. Learning a lot about the technologies and some of the science involved.

Chris Hawley replied to Forrest Frantz's discussion Mathematical Solution for Preventing a Fly-Away
"Hi Fnoop, You seem to know a couple things about this code/system.  I'm not sure it's possible without certain folks re-hijacking the question again, but can you tell me what the trade-offs or downstream needs were that led to this situation where…"

Chris Hawley replied to Forrest Frantz's discussion Mathematical Solution for Preventing a Fly-Away
"So hopefully, you now know why:
- the accelerometer is so good at sensing changes in elevation (change in movement begets acceleration just as gravity begets acceleration)
- why the gravitational constant is irrelevant (the ship only cares about…"

Chris Hawley replied to Forrest Frantz's discussion Mathematical Solution for Preventing a Fly-Away
"Okay, I'm sorry for "hijacking" the thread -- but solving this is apparently the root cause of the problem noted in the first post.

Not being able to even discuss the issue ... this seems to be a real problem if smart folks don't know the…"

Chris Hawley replied to Forrest Frantz's discussion Mathematical Solution for Preventing a Fly-Away
"Sorry Forrest, I don't usually have to be so precise in describing such things, and I'm not trying to be an expert in the technology.

If you want to be pedantic, your jet is experiencing zero acceleration in all axes.  Or if you want to be more…"

Chris Hawley replied to Forrest Frantz's discussion Mathematical Solution for Preventing a Fly-Away
"I understand what you're saying John, but you don't explain yourself, and it seems you are confusing a bit of physics and a bit of electronics and a bit of maths, when each are separate.  I'll try to explain it.

Physically, I guess acceleration is…"

Chris Hawley replied to Forrest Frantz's discussion Mathematical Solution for Preventing a Fly-Away
"Okay, stupid question maybe but it bothers me enough to cop the whipping I may so richly deserve...

Why don't we just fix, or replace the accelerometers to report dead 0 in 1G (at least until Elon has us on Mars) and have full 'fidelity' in…"

Chris Hawley replied to Harry Topley's discussion Frustrating Droid Planner Issues in IRIS
"Hi Harry, a couple things I can help with..

- make sure you are using TOWER, not Droid Planner, which was renamed at the last version (3.0). It requires an additional mini app called 3DR Services.

- to delete a mission from the bird you need to…"

Chris Hawley replied to Noah Dalton's discussion Drone Clearing Snow off Solar Panels
"Hi Noah,

I saw this and thought you might just use more solar energy...  if there's enough to generate current why not just make some black heat-absorbing vanes and attach them to the extruded frames of the panels.  Go with black on the faces if…"

Chris Hawley replied to Ankur Mohan's discussion Iris+ Flyaway due to Gyro Offset Drift? in IRIS
"Yeah, it's completely reasonable to sit and then fly as you say. And as an owner and enthusiast myself I share the view that this appears to be a preventable and systemic issue that the software should safeguard against if the componentry / firmware…"

Chris Hawley replied to Ankur Mohan's discussion Iris+ Flyaway due to Gyro Offset Drift? in IRIS
"So, not being sarcastic, but why would flying, then leaving the bird sitting and powered for a while, then flying again be mandatory? Couldn't you just pull the battery between flights and work around this problem until a fix is available? With 15…"

Chris Hawley replied to David Garcia's discussion Solo vs Iris - for a developer use case? in IRIS
"And if anyone knows why my Firefox on Android is munging my inputs to text boxes like that, please share... Sorry for the off topic note.."

Chris Hawley replied to David Garcia's discussion Solo vs Iris - for a developer use case? in IRIS
"Uneducated view alert; I am not a developer of flight telemetry apps. However it does seem that you would benefit most from using telemetry that is more prevalent in other models, like the stuff that comes through to the radios, rather than anything…"

Chris Hawley replied to Ray's discussion First crash - I guess I'm a "real" drone pilot now in IRIS
"Ray, it seems you followed the labels and that didn't help. :-)

I'm not very good but I have a simple method that keeps me safe with no extra labels... Especially when the error you describe was at the computer not on the sticks.

All I do is…"
