Arduino day 2015 and Crazyflie glove controller

Last Saturday it was Arduino day 2015 and it happens that the Arduino office in Sweden is in the same building as ours. So we where invited and presented Crazyflie. It was a really fun event with a lot of interesting people passing  by and we had a lot of fun. There was also Helium […]

DeviationTX and the Crazyflie

As many out there think is is more fun to fly the Crazyflie rather then develop upon it (like we do :-)) we have quickly looked at ways to pilot it with a RC transmitter. This forum thread is a good starting point for a developer discussion. To summarize it a bit there are many ways of […]

Crazyflie 2.0: Building a buzzer deck

While digging around in our office looking for a board we found a piezo buzzer we bought a while back. The reason for buying it was to test some buzzer functionality to the Crazyflie 2.0, but we forgot about it. But now that we found it again we got to work  We documented the build […]

Crazyflie 2.0 decks

Some time ago we decided that it would be nice to have a name for the Crazyflie expansion boards, a bit like the Arduino shields or the Beagle bone capes. We organized a poll on our website, that ended with cheating so we organized a local vote and flykit won. In second place was the deck. Over […]

Measuring propeller RPM: Part 1

We have had numerous request to get a transfer function from the motor PWM output to propeller RPM. The next step would then be to get the propeller RPM to thrust transfer function as well. With that it is easier to do calculations on the system and mathematical models. So this and probably next post […]

A week in Shenzhen

Starting up production and doing the first batch of a product is always problematic, no matter how well you try to plan it. So just like for the Crazyflie 1.0, we decided to pack our bags and leave for Shenzhen for the production of the first batch of the Crazyflie 2.0. When we launched the […]

Crazyflie 2.0 production tests

We kicked off the Crazyflie 2.0 production about one week ago and we are still working hard on ensuring the best possible quality of the production. To do so we have a test specification/plan that is executed on all the produced units. Making test protocols is something we have had some experience of in our former day-jobs, but […]

Crazyflie 2.0 expansion board template

First of all, thanks to everyone that helped us out during the pre-order. Today we are finishing the last details and tomorrow Seeedstudio will launch the production of the first Crazyflie 2.0 batch! It’s been a hectic couple of months here at Bitcraze and it feels great to finally have reached this point. For the […]

Crazyflie 2.0: The tiny modular quadcopter

This weekend we spent at the Maker Faire in Rome and got to meet lots of fellow geeks and makers. Even though it was busy times at the Bitcraze booth, we got a chance to walk around a bit and see other projects. It’s really inspiring to see what people come up with! It was […]

Crazyflie 2.0: Radio range test

As you might already know we have added a 20dBm RF amplifier to the Crazyflie 2.0 as well as to the Crazyradio PA. We have had high hopes of getting a more stable link and much better range with this. We have done a lot of tests in the building we are sitting in and […]
