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.

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...

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

Hi Kristoffer, As an extension problem to this post here. https://forum.bitcraze.io/viewtopic.php?f=20&t=4668&start=10 I will be getting the CF to look for more than two basestations. Following your advice from your call I increased the PULSE_PROCESSOR_N_BASE_STATIONS to 3, ran the CF and performed ...

We are at the point where we would like you to review the work and see if there is anything obvious that might have been missed. His message Below: We’re trying to design and implement...
