Started Jul 25, 2015 0 Replies

Hello, I came across some weird numbers and am trying to figure out what's going on.Bixler 3, with a vanilla latest Arduplane (V3.3.0, no airframe specific tuning params) flying mostly RTL and Guided…Continue

Hello, I 'm having trouble with the latest Arduplane V3.3.0 (6be0932d).Got a Pixhawk (so far working perfectly on a quad) and flashed it with the above Arduplane version. Connected to MP to be told…Continue

I 'm sorry if this has been posted before, I couldn't find another reference to it on the site. Is this the most exciting breakthrough in our lifetimes or have I missed something? It looks like the…Continue

"Connect a companion computer (a Raspberry Pi is fine for simple CV and quite cheap) to the autopilot, use whatever tools you want for CV on the companion and use dronekit to tell the autopilot what to do. You can use any GCS (MAVProxy, Mission…"

"Get a cheap but reasonably good transmitter that will last you for years and can be used across multiple models. Personally, I am quite happy with FRSky stuff, both the Taranis X9D and QX7 series have enough functionality to keep you happy for a…"

Andreas Gazis commented on andre van calster's blog post Adaptation of a ArduPilot Rover to an autonomous DonkeyCar
"Awesome, your vids always make me kind of jealous but love them. It should be able to do obstacle avoidance with Dronet, especially given that Dronet was trained on driving data."

Andreas Gazis replied to Patrick Duffy's discussion Arduplane 3.9 flyaway with bad compass
"It sounds very odd that it would fly to a false home since home is set to the arming location by default unless you had done some fairly surreal changes to the params. The only other way I can think of that this might have happened is if you armed…"

Andreas Gazis replied to Patrick Duffy's discussion Arduplane 3.9 flyaway with bad compass
"Do you have a telemetry log? I agree with Chris, sounds rather odd. I routinely ignore compass whining in planes but have COMPASS_LEARN switched on. In many of my flights, the compass is pointing totally wrong when on the ground, then I take off,…"

Andreas Gazis replied to James Brown's discussion If you were building a Drone Room in Antarctica what would you want?
"Depends how close you are to the magnetic pole I guess, it's still a long way from the edge to the pole. Also, it's mostly copters who are throwing a fit about compasses, fixed wings can generally ignore them and fly cheerfully on IMU and…"

Andreas Gazis replied to James Brown's discussion If you were building a Drone Room in Antarctica what would you want?
"3D printer. I would suggest Prusa so you can print some spare parts. You need ventilation so ideally, in an enclosure that keeps it at room temperature while dumping the fumes out. Super ideally, with a heat exchanger so you don't waste heat."

Andreas Gazis replied to ZABBIE's discussion Sudden Potential drop when taking off
"What do you mean by dropping drastically?Please look at the LiPo discharge curves here. Notice the difference in measured voltages due to increased voltage drop caused by higher current being drawn. Dropping drastically immediately the moment you…"

Andreas Gazis replied to ZABBIE's discussion Sudden Potential drop when taking off
"I am not sure if you are aware that a voltage drop is actually expected as you draw current, as the other posters point out. This is due to the battery's internal resistance and, as pointed out, your battery's nominal discharge rate is…"

Andreas Gazis replied to Colin Gibson's discussion Parafoil Return to Point Descent Vehicle
"Um, what? What is a twist dive and what does it have to do with anything? I am talking about a spiral dive, see here: https://xcmag.com/news/dive-dive-dive/ one of the most basic rapid descent tricks any paraglider pilots learns. As to how much…"

Andreas Gazis replied to Colin Gibson's discussion Parafoil Return to Point Descent Vehicle
"Increase. Higher weight -> higher speed. Spiral dive is never uncontrolled or it wouldn't be used as a standard descent manoeuvre in paragliding so your risk of failure is damn small. What you don't have control over is direction while…"

Andreas Gazis replied to Colin Gibson's discussion Parafoil Return to Point Descent Vehicle
"If you want to burn altitude using a parafoil, use a spiral dive (look for paraglider spiral dive on youtube). You will drift with the wind but will get to lower altitudes where wind speeds will be less extreme. Depending on the conditions and your…"

Yay a fellow drone person! Are you free for a coffee over the weekend?

Best
