About half a year ago,I posted something about an ESC I was developing, receiving good comments how other builders already achieved some of my things ages ago or are just in the final stages of working out the new ESC at their lab (see px4ESC for exa
I'm developing the control software for my own ESC and recognized the need for a simulation model so that I can run my algorithm against it, so that I can see the effect of a variety of issues. Looking around the web, I saw that some simulators exist

Hello all,
I am exploring a crazy idea that just might save lives. Is it possible, I don't know. You guys are the experts. That i
This discussion is a proposal towards an approach that allows an autonomous aircraft to detect sensor anomalies without duplicating sensors. I'm going to discuss this topic from the perspective of multirotors only, since it's a bit simpler, but it wo

I use APM:Copter and the newer beta firmware to take advantage of geographical distance camera triggering. Did a test some days ago and it works. The downside is that this beta version seems to overburden the processor, causing telemetry messa

I played around with mission planner and today wanted to do my first camera mission. Unfortunately I clicked to update the apm software yesterday, which radically changed the functionality, so I had to think in the field...

Just tried to configure my shutter. I'm using an opto-isolator with CHDK functionality. The idea is that I should be able to pull a pin high for a specified number of ms, configure a CHDK script to measure the time that it's raised and then tak

I have a MAX7456 chip, which is a relatively simple OSD chip. It's fitted on a breakout board and you talk to it through an SPI.
I tried to find out a way to easily connect the chip on the ardupilot, but the current SPI is used I think for the A

I'm reviewing the code whilst finishing off on the last details on the APM (voltage monitor, xbee connection, etc.) . I noticed that the APM makes rather heavy use of the eeprom also in flight.
From what I gather, the eeprom is written to a
Today I built in the Ardupilot Mega for the first time into a plane to verify the functioning of Stabilize and FBW_A modes. I just wanted to get some debug output and see the servo's functioning. After discovering that my GPS needed a reflash and the
