Thanks to some of the motor mount feedback we have now managed to improve the motor mount a bit. It now has a longer extruded cylinder and a larger stop to prevent the motor form popping out when landing hard. This should add a bit more protection but it is still a good idea to [...]

One week of flying
December 11th, 2012 
arnaud After one week of flying the new copters we have to say that they are preforming very well. We’ve done a lot of crashes but only had one incident with a bent axis on one of the motors which we fixed by replacing the motor. We have noticed that using some radio channels in combination [...]
Pre-series tested
December 4th, 2012 Marcus On Wednesday we assembled and tested all of the kits in the pre-series. We ran though the production tests, that will be used once the kits are produced, as verification. Since we can’t test that they really can fly the test isn’t covering everything but it checks most of the components. One of the units [...]
Protective frame prototype
October 29th, 2012 tobias While we are waiting for the pre-series to arrive, which hopefully will be within 4-5 weeks, we have tested this idea we have had for a while. On the Crazyflie PCB we placed mounting holes in each corner for the possibility to add e.g. a landing gear, canopy or maybe a protective frame. The holes [...]
Tools
October 1st, 2012 Marcus One of the goals during this project has been to only use open-source tools for development. The main incentive for this is that we want everyone to be able to take part in the development and look at the all the parts of it once it has has been released. Also it was a great [...]
Board outline
August 27th, 2012 Marcus The coming week we are reviewing the new revision of the hardware before we press the order button. With the previous prototype we had a few violent incidents where one of the arms broke off. Fixing it wasn’t to hard. We used an aluminium tube we cut to the right size and glued over the [...]
Mounting the motors
February 13th, 2012 Marcus One of the ideas with the Crazyflie was to make a simple flying platform and what’s simpler than just attaching the motors directly to the PCB? On our first prototypes we used hot-glue to attach the motors which work out pretty well. The problem was that when you crashed the motors often came loose, and [...]
