It's been a while since I've posted an update on the progress of the AutoQuad flight controller.  The event that we've all been waiting for has arrived with ST Micro's announcement and subsequent release of their STM32F4 product line.  As expected, the micro-controller is pin for pin compatible with…

Recently the Chinese ESC design utilizing the ATMEGA which we have been flashing with Bernard Konze's firmware has been disappearing from the market.  This was the push I needed to finally decide to design and build a replacement.  Collaborating with a friend, we worked on it over the summer.  It is finished and I think it came out pretty well.  I call it ESC32:…

For those following this saga, version 6.1 of the AutoQuad board is complete and has passed initial testing.  I have taken the 5.0 design and added features that should make it more flexible and expandable while increasing performance.  Here is a summary of specifications:

The distributors finally got in some of the new ST Micro STM32F2 series uControllers and I grabbed a few.  I was able to "shoehorn" one into a ver5 board as the pinout is close to compatible with the performance STM32F1 series.  Spent a few days rewriting the device drivers and am very impressed with this…

I know, the world probably has enough flying machine projects, but here is yet another one.  AutoQuad's original design goal was high precision autonomous flight.  It took five prototypes before I was happy with the hardware.  The current prototype, AQv5, is showing very promising results.  In fact, there is little left to…
