is it possible to buy your hardware ? i have no equipment here to realize your pcb soldering components.

let me know

(pcb with components soldered) i have no equipment to build it at home

Thanks

It had an Oreston f1.8 lens. I probably used it more than he did, especially when I first started taking my first serious BW shots on TriX or HP5. It was a fine camera for it’s time and capable in the right hands. I have fond memories of it, particularly as I did my first real work on it and the fact that I associate it with my late father, the person who got me interested in photography in the first place.

Regards

Byron.

It is only the build directory that you are doing it in.

@Tormod: Yes it does not really make sense I agree, it was something I carried over from other documentations how to build the toolchain.

There is no space for $150 motor controller in a $400 aircraft sadly. :( Yes each motor is getting one stm32. I know several people did combine the control into one mcu or even one board. I really don’t like those solutions at all. It is a single point of failure, as well as the timing requirements become even more complicated if you have to drive two motors from one mcu. Also controlling the motor controllers using PWM as signal input is not as bad as you may think. It is really very robust to EMI noise. The only disadvantage is that you don’t get any data back from the controller about it’s current speed and torque. That would be very useful information to the controller.

@Angelo Rosselli: No, the implementation is for cortex m3 stm32 mcu. I am not planning to port the code to atmega.
