It’s been an incredible week seeing people from all over the world getting their Crazyflies into the air!! We have seen videos of people doing crazy stuff we never thought of, 3D models of cases and frames on Thingiverse and of course a lot of images of people unpacking and assembling their Crazyflies. The wiki [...]

First FPV flight test
March 12th, 2013 
arnaud The community interest for FPV flight made us buy a light weight analog FPV kits a while a go. We bought the 5.8GHz micro combo set from fpvhobby to do a first test. It took a little while to solder things together but it wasn’t that bad. We soldered the camera and the transmitter power [...]
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 [...]
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 [...]
Inductive charging hack
September 24th, 2012 arnaud After the LED hack we are back with an inductive charging hack! The idea of charging Crazyflie inductively is almost as old as the copter itself. Last week we received a Palm Touchstone charging kit that we ordered. Like many phone hacks using this inductive charger we dismounted the receiving coil and electronic and attach [...]
LED hack
September 17th, 2012 tobias When I was shopping for some ink-cartridge at this Swedish accessory store named Kjell&Co I also bought one of these 12V LED lamps. I didn’t buy it to actually use it instead I bought it to have a look inside. I cracked it open when I came home and found, not so surprisingly, a lot [...]
Sensor poll
September 10th, 2012 tobias If you have been reading our previous blog post you know that we redesigned the Crazyflie to use the MPU6050 instead of the IDG500-ISZ500-BMA145 combo. This was done because the IDG500 became obsolete, recently we found out it was because Invensens had production problems with this sensor, anyway when redesigning we managed to squeeze in [...]
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 [...]
Summertime update
July 23rd, 2012 Marcus We haven’t seen any more problems with the prototypes since we exchanged the MPU-6050. All of the changes for the new prototype has now been tested and we are currently modifying the board design to fix the bugs that we have found. Then it’s time to order a new batch of prototypes. Our hope is [...]
