As promised here’s a new Monday post. Below are some screenshots of our PC side/ground station software written in Python using pyUSB, pyGame and PyQt4. It’s far from finished but it’s good enough for us to get real-time plots of flight data and control parameters. Unfortunatly we did not have a flying prototype at hand while writing this post so the data is somewhat fake but good enough to show the concept.
Hello,
It is now Monday evening which is now our official meeting day within the Crazyflie team. From now on we intend to post a progress update every Monday evening here at the Bitcraze blog. First of we can tell you that we have, since two weeks, received our second round of prototypes. For the second round of prototypes we did some small fixes and improvements which unfortunately did not all work.
Other then that we are getting close to a pretty well working flying PCB.
We have tested a couple of LiPo batteries in different sizes from Fullriver. We decided to go for the 170mAh 25C battery which gives us about 7min of flight time but doesn’t add to much weight.
We have tested a lot of different pager motors in mainly the sizes 6×14 and 6×15 mm. Many of them are not the best quality but we found a good one, 2.5ohm, 6x15mm motor which is of good quality and high performance.
What is left now is the motor mountings which has turned out to be a time consuming task for us since none of us has any direct mechanical/plastic experience. We also have loads of other tasks but let’s take it one step at a time.
There is a short video of the new prototype flying that somebody took when we visited Techfest if you want to have a look.

We uploaded some pictures from Techfest to a Picasa album. We are also working on cutting the video material that we have into something that’s a bit better. If you have any good pictures that you took or any scans of articles that was in the news papers don’t hesitate to send them over. The email is on the About page.
We upload there the posters used at Techfest. They describe the basic components of the new crazyflie version. A video will follow.
We would like to thanks everyone that came to see us at Techfest-2012 for there enthusiasm for our project. That’s was a a really awesome experience and gives us a lot of energy to continue!
From the 6th to the 8th of January we are exhibiting the Crazyflie at the Techfest at IIT Bombay in India. If you are there come by our exhibition in the Exhibitions tent and have a look!
