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

Re: flipping the motor direction in the firmware.

that does get the drone off the ground, but the yaw is uncontrollable. it spins really fast then crashes.

I tried again in our lab, clean install new drone. all works ok! So not sure what that was.

Just waiting now for my engineer friend to finalise the modifications to the

Code: Select all

class LighthouseBsGeoEstimator
before we move on to integrating it into the newest version of the Lighthouse Tab.
