"Looks like a nice product that works towards airspace integration but please keep the marketing hype in check: "able to detect all aircraft threats within a 30 statue mile radius in real time". Really? ADS-B Out is not mandated for general…"
"There is no Attitude Slow. If you set both to zero you will get Attitude NO, meaning no attitude data will be logged. This may be OK, depending on what you want, and will certainly extend the logging time."
"It could affect the pseudo range, Doppler and carrier phase measurements , but the extent to which it would I don't know. Velocity measurement assumes there is a drift rate in the RX clock. If the regular XO clock drift is nicely linear with time…"

"Hello Max,
At each measurement epoch the receiver clock error is modeled as a fixed drift rate (s/s). This is all that is possible/needed as the velocity solution is a least squares calculation using data from a single measurement period.…"

"Serious? DroneCon is not before/after AVC???"
"I have configured the SP0 pin per the data sheet for the next-to-LSb to be zero and have tried 0xB0 and 0xB1 in accordance with the data sheet which may of course be wrong. I can set up to just bang all the addresses and look for a response though……"
"Hi Nick,
The files you uploaded are for the 21000 series devices, which are 2 axis devices, versus the 21100 series devices which are 6+3 axis devices. Although there are some similarities there are very significant differences. Is there some…"

"Does anybody have any actual experience with the Maxim21100? I have a couple sample parts but thus far have not been able to get anything out of them. Of course the data sheet doesn't help - it is missing all the register bitfield info, etc. etc."
"@Ranaud - No. If you want plug and play, look at the SF02. The SF02 is more money, but also 4x the range.
@Laser Developer - I have also been testing the SF02 and have been really happy with it thus far. A cursory read of the OSLRF-01 data sheet…"

"Hi Robert,
Seems like that is just a programming issue to me. Why can't it lay one layer down pulling the fiber left/right and the next layer pulling the fiber front/back? I think weave is mostly just a convenience as you can handle fabric whereas…"

"OK Robert,
I'll be twisting Peter's arm to come up with something for the plane course that will take at least an hour, maybe 2 hours - 30 or 40 laps of the reservoir perhaps? :) Then we will see…
I'll start planning entertainment now. Nobody…"

"@Macboffin - your comment about shiny polished finish is incorrect. All modern high performance sailplanes have highly polished finishes which reduce skin friction drag and allows for laminar flow. Negative effects of rain, bugs, etc on the…"
"Correct - only 100 steps. I don't remember what the 3dr ppm has for resolution but the last ppm encoder I programmed I used 1000 steps."
"This is documented in the wiki - http://code.google.com/p/ardupilot-mega/wiki/Voltage
If you are running high voltage you may need to wire a custom voltage divider. Otherwise it should be fairly plug and play."

"If you are using the airspeed sensor, then the throttle is used for altiude control. Techinically, it is used for total energy control, but you can think of it as altitude control. Nominal airspeed is set as a parameter."
