Firmware and dwm1000 nodes

DWM1000 nodes Last hacking-Friday we have had some time to put together the DWM1000 boards we ordered during the summer. The DWM1000 from Decawave is an ultra-wide-band ieee802.15.4 radio transceiver that can very precisely timestamp packets arrival and departure. More simply it means that it is a standard and it can be used to implement a […]

Big quad deck and iOS bootloader

Big Quad Deck So last week we received the first prototypes of the Big-quad-deck. With this deck it will be possible to transform the small Crazyflie 2.0 into a flight controller of a bigger quad. It does this by using some of the deck port pins to drive brushless motorcontrollers. This has been explained how […]

Crazyflie Nano (1.0) and Crazyflie 2.0 firmwares are now merged

The summer here in Sweden is what it is, barely warm enough to earning the name summer. Every year you hope that this year will be the good year and most often you get disappointed. It however encourage productivity instead of  lying on a beach which is a good thing. So as we are currently […]

Working on new decks

Switching to docker

Historically our server environment has been pretty basic and manual. The main focus in the company has been to build awesome copters, so managing the infrastructure for delivering services such as web, forum and wiki has been low priority. The services has been up and running most of the time, which after all is the […]

Keeping track of production testing

During the design-phase of the Crazyflie 2.0 products last year, we sat down and had a long discussion about testing. In order to make sure things runs smoothly, it’s best to make sure that the hardware you’re designing can be tested properly in manufacturing. It could be as simple as adding a few test-points or a bit […]

Interfacing Crazyflie 2.0 with external motor controllers

So last week we had a bit of fun connecting the Crazyflie 2.0 to a bigger quad frame. This is something we did a while ago with the Crazyflie Nano (1.0) , see this forum thread. This time it was the Crazyflie 2.0 turn and we wanted to use the deck port and the proto-deck […]

Sniffing Crazyflie’s radio with HackRF blue

While we where in the US we finally received our long-awaited HackRF Blue. Our plan was to use it to sniff the Crazyradio and Crazyflie communication in order to be able to better debug the communication. HackRF Blue is a lower cost build of the open source HackRF One. It is a Software Defined Radio […]

Autonomous flight using Kinect2 for position control

So we are back at our office and the “great” Swedish weather. We don’t miss the California sunshine at all, we promise. We have spent the last days documenting the setup we used to fly the Crazyflie autonomous using the Kinect2 for position control. It is still a work in progress but we think it […]
