Re: Using 350 mAh - 25 C Battery on CF2

I also did some tests, want to share it here. First I have connected CF to a desktop power supply on 3.9V. Holding it on my hands, connected via CF Client then tried to take-off. Just by an inspection, I saw numbers higher than 3.8 A for a short time. The stock battery is able to give (0.25(Ah)*15C=...

Re: Using 350 mAh - 25 C Battery on CF2

Hi Tobias, I have ordered only one to test it if it will work or not but the situtation is more complicated now :) So you think that kind of battery with similar specs should work with crazyflie, right? (I can not see any reasons to not). I was checking this post (https://forum.bitcraze.io/viewtopic...

Using 350 mAh - 25 C Battery on CF2

Hi all, We wanted to try installing a bigger battery like in the picture (3.7V (1S), 350 mAh - 25C) on CF2. Yet, it does not even takeoff. When we send commands to take off it either turn itself off or some propellers are strangely rotating while others are stationary. I am %100 sure about our exter...

RZR Release Time

Hi all, I am not sure if I have opened this topic in right subject or not, so sorry if I am wrong. I am working on my Master's Thesis right now and need to use a platform either built with BQ-Deck or (hopefully) RZR. As I followed from blog news, RZR should be out any time soon. So, my question is, ...

Re: LPS with Flow Deck and uneven terrain

Hi Carlos,

Would you mind to share with me how you manage to ignore Z data from UWB (I assume you did this, anyway I will be happy to learn what you did and how)? We are dealing with the same system now (UWB + Flow Deck) and I am searching for some ways to improve Z performance.

Thanks in advance,

Re: LPS System - Altitude Hold (z-position) Problem

Hi again, We have switched the system mode to TWR and conducted some tests. In the videos above, we placed crazyflie in the pre-measured points in the arena, and look for the overall estimated position of cf in addition to distance to every node. Firstly, here are the videos: https://www.youtube.com...

Re: LPS System - Altitude Hold (z-position) Problem

Hi kristoffer, After some trials, I want to explain you the situation we are in now. First of all, I upgraded the crazyflies' and nodes' firmwares to the latest one, I compiled and uploaded them. There is no connectivity issue right now, everything is fine and green, both in TWR and TDoA modes. As a...

Re: HITL and SITL for crazyflie

Hi, The multi-uav-final branch works fine for me with 5-6 cfs, but not 7. I compared my CPU (Intel® Core™ i7-6700HQ CPU @ 2.60GHz × 8 ) with yours and its an expected result I guess (I have same RAM size). When it comes to HITL, I wonder did you ever tried to fly multi cfs in HITL mode, or a single ...
