Last week at Devoxx UK

Like we mentioned a couple of weeks ago we went to Devoxx UK last week exhibiting the Crazyflie. We got a chance to do lots of fun things, like flying the FPV quad in the keynote and also over the exhibition floor. The image is a bit faded, but we had the luck of having […]

Things happening in the community

It’s been a while since we summed up things happening in the community so here’s some of the things that are happening. There’s lots of more things, so if you think we are missing something, then post it in the comments below. Ralph has been doing some work on an semi-automatic flip feature in the […]

NeoPixel driver for the Crazyflie’s STM32

A couple of weeks ago we found the NeoPixel ring from Adafruit at a local shop, we had to attach this neat board to our copter and see what cool effect we could make with it. The ring has 16 RGB LEDs that can be driven independently with only one data wire. The LEDs the Neopixel […]

Brushless driver for the Crazyflie

A while ago I started working on a brushless motor control driver for the Crazyflie. I implemented most of it but did not really have time to test it. Recently we have gotten some request and questions about it so we took some time to do some further testing. Implementing a brushless motor control driver […]

Crazyflie with GPS, round 2

A couple of weeks ago we attached a uBlox MAX-7 GPS module to the Crazyflie (blog post). Back then it was mostly a proof of concept, all we did was to re-route the raw GPS data (in text NMEA format) directly to the PC using the Crazyflie text console port. This allowed us to quickly […]

Trying out GPS with the Crazyflie

Before the holidays we said that we would be doing some testing with attaching a GPS receiver to the Crazyflie. For now it’s just a bit of a quick hack, but we are planning on doing more development. Here’s a quick summary of where we’re currently at (yes, that’s a bad joke..). We attached a […]

Testing ST MEMS sensors

For a while Invensense’s gyros has been the MEMS sensors to use in multirotor  applications due to their good performance and vibration rejection. ST Microelectronics are also big when it comes to MEMS sensors but their gyros has not been that good when it comes to handle vibrations. In the beginning if 2013 they released […]

Community development

This Monday post we are devoting to the community development and we will try to give a short summary of what is going on there. We recently haven’t our selves had that much time to help out with this development, something we intend to change, so all credit goes to the community! A port of […]

Crazyflie KiCad project released

We finally got the time to clean-up the Crazyflie kicad project enough to make it publicly available.  It is not in a perfect shape but should be good enough to use and learn from. It’s a 4 layer board with signal layers on bottom and top and power planes in the middle. We have also […]
