Nathaniel McMahon replied to Gabriel DeVault's discussion How do I set/determine min/max PWM values sent to ESC's during flight?
"Ha yes I have the same issue 1848 is the max output by the fc,Did you find a fix other than calibrating the esc's?"

"My props are also hard mounted. I'm thinking it's more to do with a balance between UAV PID responsiveness and the shock absorbers in the gimbal mount."

I've been flying with my alexmos Gimbal with a Sony A7r and occasionally get judders and shake in the footage. I tried yesterday without the in camera stabilization and it's a nightmare (hats off to the Sony). Here's a quick vid i've upped from…

Nathaniel McMahon replied to Nicholas Witham's discussion Solo link in a DIY Drone
"Yep I'm interested also. But I think it utilizes the solo onboard Linux computer?? So no it's not an simple integration. But you could buy a solo and change everything else."

Nathaniel McMahon replied to Paulo Neves's discussion Campaign for Sony Multiport protocol reverse engineering
"There's many commercial solutions like this and code is pretty much out there for simple triggering and zoom so that's not so much a problem. But full control has not been reversed engineered although it seems some are looking into it it is quite…"

"The uart is only from FC to their unit. Not to the camera."

"My mistake. Further investigation and it communicates through infra red sensor. I believe it has exposure control via some battery compartment connection. But that's it."

"I think the guys behind air commander have pretty much mapped all functions now. also have uart control. Which it was open source though. "

Nathaniel McMahon replied to Christian Mauch's discussion Safety First: 100A & 200A Hall Sensor with BEC for Pixhawk / APM
"Hi Christian, 
Can you clarify something for me. 
I already am using your a single MAUCH_HS-200-HV on my pixhawk 2.1 Octo setup. 
I either use two batteries or 4 (2 in 2 groups)
I am wondering whether I should get an extra hs-200-hv for the other…"

Nathaniel McMahon replied to Nathaniel McMahon's discussion Octo overshoots Yaw by about 80% PID's don't seem to make any difference???
"Sorry I should add that i've adjusted PID's and ran several autotunes but no real change. incresing the I value to 1/10th of P and beyond yealds no discernible change. I've attached a snapshot of my current PID's above."

Vehicle: octo running arducopter latest build 3.5.3. frame 910mm 6kg without payload.I've just swapped over to a Pixhawk 2 FC and i've noticed a strange behavior with Yaw before and after tuning and auto tuning. The copter keeps spinning after yaw…

Nathaniel McMahon replied to Konstantin Romanov's discussion Simple remote shutter trigger for Xiaomi Yi camera
"Great hack and post, thanks Konstantin.
Just made your switch and It works great when I pass a 5v current through it, (My FC is a Navio2 based on a pixhawk and has RC out at 5v so I just added 200Ohm resistor). But I can't seem to get the FC to…"
