Ryan Alexander Bahr commented on PX4's blog post PX4FLOW Release"I've been waiting for the optical flow sensor for quite some time. I know they said here they don't plan to introduce a low cost version but I hope that the Arducopter version isn't in that category."
Ryan Alexander Bahr posted a discussionIssues connecting through USB/3DR Radio
So I've had my APM 2 sitting in its static-protection bag for about 7 months now, as I have been occupied with life. That being said, I remember when I was first messing with it I didn't have any issues that I could recognize. It was rather straight forward to hook up and I could read all the status's/orientation through either the 3dr radio (hitting control-A after setting the correct Baud rate/port) or even directly connected through USB and with the mission planner software. Now when I…See More
Ryan Alexander Bahr commented on Adam AKAV8R's blog post GoPro 3 Has Arrived !"Just preordered mine! Black edition. Hard to believe it does 4K video, but who the hell even has a monitor to handle that. At 12 fps its barely worth it, but who knows what may turn up. I wonder how speeds of the Memory card are going to come into…"
Ryan Alexander Bahr commented on Geoffrey Preston's blog post More Antenna Alternatives"Sorry I should have addressed that at @Travis.Even for circuit boards, I believe I would rather have it insulated as much as possible and create my own connections. But I believe for an Antenna, if it wasn't…"

Ryan Alexander Bahr commented on Swaroop Kagli's blog post OpenUPS - a neat power supply for RC projects!"As far as constant voltage, constant power supplies... One of my favorites has been this little thing off eBay. CC, CV driver
It's 7-35 in and 1.25-30V out up to 3 amps (15 watts reg, 25 with heatsink... Do the math for the…"
Ryan Alexander Bahr commented on Roy Brewer's blog post Robot Control course from Coursera featuring quadrotor control"Don't worry about how long it takes for this class to start, this guy was my ECE 3085 professor and he is nothing short of awesome. He is enthusiastic and knows his stuff. That is a parrot ar drone. His focus isn't so much about the…"

This seems to have been sitting here for about a week so I'll help out and just go down the page in order.

Ryan Alexander Bahr commented on Chris Anderson's blog post Using long-exposure photography to study helicopter physics"Though I am sure there are other factors, I believe the reason he was stating that we should know that chinhook was fastest was due to the fact that the top limiting speed of the blade due to the speed of sound and pitch on the retreating…"
Ryan Alexander Bahr commented on Mark Harrison's blog post Strain Relieving Case for 3DR ground module"@ Veikko
Looking at his icons, it seems like he is using VMWare. I use Parallels 7 on my Mac, and I use VMware on PC. Overall I enjoy Parallels tenfold over VMWare, but VMware is better if you plan to move your virtual machines across PCs quite…"
Ryan Alexander Bahr commented on CrashingDutchman's blog post X550 Glass Fiber Quadcopter frame 550mm"Don't cheap out and buy this frame on ebay! I bought a x525 and and x450. The x525 is similar to this except springs on the arms, but not a single arm had properly drilled holes which means that what you'd expect would be easy assembly…"
Ryan Alexander Bahr replied to maroFX's discussion all 4 motors shut down for1 sec during flight. What's that? in the group ArduCopter User Group"You have it set to low cut off?
That generally means that at low voltages (lets say when you give full thrust, 4 props all draining a battery at once) the ESC's may shut down/ slow down (depending on ESC) to protect your lipo battery. You want…"
Ryan Alexander Bahr replied to Richard's discussion First APM2 Build for Aerial Photography to create DEM,DSM for GIS purposes - Ursus Airframe"That looks so awesome. I'm new to this and I'm not sure of the exact term of 'weatherized,' or if the USB-B plug is actually exposed ( I doubt you did that), but my first impressions are that it is. I get plugs like these for…"
Ryan Alexander Bahr commented on John Campen's blog post Rubber suspended mounting of the APM board not a good idea"It's cool to read all the experience here with different noise dampening systems, aquatic silicon is something I would've never thought of myself, even though I have some extra sitting around my house. Saving me a lot of time when I…"
Ryan Alexander Bahr commented on John Campen's blog post Rubber suspended mounting of the APM board not a good idea"@ Robert & Sami. I've completely forgot about the resonant frequency of the frame, as well as each component that would have dampening in between would have its own resonating frequency, which would be lot to keep track of if you did add…"

- About Me:
- I'm 22, based in Atlanta, American/German/French, and studying Electrical Engineering. I still have a lot to learn, but hope to constantly gain experience through hands on and studying.
- Tell us a bit about your UAV interest
- I've had interest in it for a while, but ultimately after watching the U of P videos back in 2010. I've been studying hard and after gaining some circuit experience I decided that UAV experience would help with my own studies, as well as be an enjoyable hobby. Hopefully I will gain enough knowledge to better the community.
