Bortek replied to Bortek's discussion Arducoppter arming without GPS fix. It should NOT!
"OKej , then I have somehow misunderstood it. 

But what does Skip GPS mean in the ARMING_CHECK parameter? Is it checking if GPS module is present?"

"Hi

Do yo know how much delay do yo get between the actual GPS position and when the Geo tag is written to the image in the camera?

What is the interface between Pixhawk and MicroPC and MicroPC and Camera ?"

Bortek replied to Ned Horning's discussion The right tool for the job in Agricultural UAVs
"Thanks Ned , I will give it a try. I wonder what are the drawbacks of setting a filter on the camera lens instead of inserting it inside? Of course I willhave to first take out the IR filter. But the ability to so easily interchange filters for exam…"

"What are the alternatives when it comes to purchasing red filter for S100 ?
I cannot find anything more than just publiclabs DIY kit. Can Anyone post some links to where can I buy one? "

"I wonder if anyone used red filter instead of blue. There are reasearch notes on Publiclab which tells that there is better contrast between healthy and poor plants when using red filter. Here are some of them

Bortek commented on Jeff Taylor's blog post New, Higher Performance NDVI Converted Cameras
"Jeff thanks for the quick reply. That clarifies that sx260 is not an option.

I've read that GPS lag in s100 is over a second which makes it useless. Is that true? Having Images gps tagged by camera is very practical but if lag is too high it makes…"

Bortek commented on Jeff Taylor's blog post New, Higher Performance NDVI Converted Cameras
"Help! I cannot decide between S110 (or S100) and SX260 to be converted and used for NDVI imagery. 

Any experience on these two cameras ?"

"Hi

It is the first day of 2016 today and there must be some progress in this area. I wonder what are the hot cameras in the topic today? Are people still using NEX5 and EOS-M ?"

Bortek commented on Norman Sanchez's blog post Complete Guide to lipo batteries
"I wonder about the behavior of the batteries I use on my hexacopter. It is 4S 5000mAh which I connected in parallel, that it 10000mA in total. When I fly it without a load (without gimbal+camera) I get more flight time which is of course self explan…"

Bortek replied to xoltri's discussion Pixhawk causing motor sync issues.
"Craig and OG, thanks for quick reply.

Actually what I though was a problem was not really a problem with Sync or rather no problem at all. What happened was the following: when I draw up the throttle stick not all the motors started to spin at the…"

"I am sitting with the Hexa and Afro 20A ESC and expiriencing this same issue.
Is there any "consensus" about the problem and a common solution? 
Is latest SimonK firmware working with Afro ESC with Pixhawk?
Will reflashing ESC with BLHeli fix the pr…"

Bortek replied to Hugues's discussion How to assign a receiver channel as a pass-thru Pixhawk ? in ArduCopter User Group
"Here is an update after I have done my tests yesterday. I can confirm that passthrough works, at least for my needs, which is passing through radio signal to gimbal controller (Martinez with Alexmos in my case) to control camera pitch. I had connect…"

"Olex I am curious how did you achive that? That will be my backup plan in case if passthrough to motor out will not work.

How do you setup for example to passthrough RC8 fed via SBUX to AUX1 ?"

Bortek replied to Hugues's discussion How to assign a receiver channel as a pass-thru Pixhawk ? in ArduCopter User Group
"Hugues, unfortunetely not all receivers support that. For example Futaba R6303S has 3 PWM outputs and one SBUS. You get 8 or 10 channels via SBUS while direct PWM outputs you have a choice of different channel groups on output1 and output2 for examp…"
