"I just got the Sf11 in mail. when I connect the cable size I get a constant stream of data - that looks pretty good. When I connect the USB side through lightware terminal no ports show up or are recognized. I am using the most up-to date terminal…"

Steve replied to Ethan's discussion Should I use PX4 flight control stack or the APM 3.3 for Pixhawk?
"I use the Ardupilot codebase in a university setting. I personally found the Ardupilot code to be much easier to follow and more straightforward to change. I also find that the developer website for ardupilot to be pretty well documented. Ardupilot…"

Steve commented on Laser Developer's blog post The SF11/C laser altimeter - awesome performance for $249
"I've used some ToF sensors that were very susceptible to that issue and I've talked to people who have used lidarlite and they said there were issues going from one surface type to another. Just curious if others have had similar issues."

"Do these work well over pavement? Specifically going from shade to non-shade? Any data?"

Steve replied to Gerhard Laubscher's discussion Autotune successfull on low kv Motors, heavier Quads, advice?
"I need to double check but I think its a 4S5P pack so 17000 mah @ 2C rating(at most) I can draw about 34 amps. I think on a slightly less heavy version I flew it for about 25 minutes. I recently added about 300g which I think from calc's didn't pose…"

"Thank you! I will have to confirm my pixhawk's are both up to date. I was fairly certain that my newer vehicle had most up to date firmware but will double check."

"Thanks Henry for looking

Couple things - I'm fairly certain on the loiter the throttle mid was set at 550. I know the alt_hold_fail.bin was 100%. But regardless of it if was 400,500 etc..I don't see why the throttle out for a moment drops to 200. …"

"I followed steps on the wiki for setting thr mid and all other needed calibrations. On previous flights I looked at imu and saw that vibe looked great so I tried originally to go for loiter right off the bat (since I never had problem with alt hold…"

Steve replied to Gerhard Laubscher's discussion Autotune successfull on low kv Motors, heavier Quads, advice?
"Did you have to change your throttle gains much to get alt-hold to work?

I am having similar problem with two different vehicles(110kv(4kg) and 360kv(2kg)) with pretty much identical problems. When I switch to alt-hold the vehicle drops couple…"

Steve replied to Volta Robots's discussion Companion computers in Volta Robots
"I like the decoupling of boards as well- our group has had a lot of success with both apm/pixhawks talking with separate onboard computers. Also from safety side I think it makes more sense. Other computers that should be looked at are Gigabyte…"

Steve replied to Sj's discussion How to output PWM values from UART of PX4 via BeagleBone while using ArduPilot code
"I'd recommend building the UART_test in /ardupilot/libraries/AP_HAL/examples/UART_test to see if firstly you have the setup correct and that you are indeed getting anything.

Where is that code you have above live? Are you enabling the uartE? Are…"

"@Thomas we love to get together(again). We've all got to see some of the very neat stuff you are doing. We'd love  to get our hands on IR-lock. I'll email you and try and get a meeting together..or at least a fly-day"

"We do not use lines/tiles per se. In our state vector we keep 16 3D feature points that help us navigate. We use a corner harris method with some additional steps to pick the features to track. We also have to add/remove features from the state…"

"Some of it is mentioned on the website. Its pretty much a flying i7 with very minimal add-ons. The frame is carbon rods from hobbyking(super light). Motors are baby-beasts(from HK) with afro-escs(12A). The i7 was stripped of its case and a 3D…"

"The figure is from the rules. I don't know why they decided to use that. A team from Maryland built a cyclocopter and flew it this year. It was a smaller version of this: https://www.youtube.com/watch?v=mwgzCg9suTI

It flew pretty good but the…"
