Re: Erratic and Conflicting Roll, Pitch and Yaw values.

Wow, yeah good to know. thanks for the suggestion. I commented out the two lines and flashed the CF. It is a little more stable when flipped, But has this creeping error that then kind of snaps back. The Drone does fly but creeps up int he Z axis and the Y axis a little too before snapping back. Any...

Re: CF having trouble reciveing over 4 lightouses.

Ah ok. Yeah this seems like a hardware issue rather than a software issue? I cant tell from that response.

But anyway something to look forward to in the future!

Re: Erratic and Conflicting Roll, Pitch and Yaw values.

There are 4BS two in the standard positions and one each immediateley below them about 350mm off the ground. We place the CF on the floor and run the...

CF having trouble reciveing over 4 lightouses.

Hi all, The cf can recieve and fly from 4 basestations. But over 4 is causing it to recieve nothing at all. It can recieve 5 sketchily, but cannot fly. 6 and above it completley checks out. the board goes yellow. the tab says none of them are being recieved. the KALMAN task is at 15% when 4 are on ,...

Re: Using v2 lighthouses facing upwards

Hi all, After all these heavy modifications to get_bs_geometry.py using Kristoffer Script from early in this thread we pulled something together that got the BS in kind of the right place, but were having serious problem with the averaging of the quaternions. Then we realised (after installing all t...

Hi All, I am getting some strange readings from the state estimate log that I just cant iron out enough for them to be useable. Across three different drones. with completely stock firmware.

Re: Charging unprotected batteries via USB.

The charger will work fine and is designed for LiPo and will cut off at 4.2V. The depletion though should perhaps be handled a bit better and is the most common risk I see. Something as simple as shutting off the system if the voltage has been lower then 2.9V for e.g. 3 seconds. This should prefera...

PyQt question: Connect the X button to a function in a Tab

I have a tab in the client that listens for data from a socket. When I close the client I cant get the Tab to shut down the socket. I have tried a number of ways to trigger a function on close but failing. Here is the closest example on stack overflow I can find. https://stackoverflow.com/questions/...

Battery Advice

I have a set of Turnigy Li Po 300mAh 20-40C batteries.
Is there any way of telling when they start to become dangerous?
A new battery measures around 8.18mm a used one (cannot tell you how long sorry) has swollen up to 8.74mm.


Cheers
Joe
