ian commented on Chris Anderson's blog post Introduction to PixHawk ground control station (including source code)
"Hi PixHawk,

Thanks for the reply.

I hadn't considered all of the communication decoding.

I think I saw someone from your group post to the ROS mailing list regarding LCM:

I…"

"I didn't realize there was a more recent posting of the video here. I just wrote a comment at this post:

that was mostly referencing what I had seen in this recent PixHawk video..."

"I'm curious of other's opinion, or if the PixHawk developers have time to respond:
-it seems most of the current implementation could easily be reproduced in HTML/5, the exception being the graphing component, since aside from flot and a few other…"

ian commented on Reto's blog post Xbee socket board
"Thanks for the comments Jordi. Since I already have 3.3V levels on my uC though, I was mainly curious about assembly differences. Given the negative comments on the sparkfun site regarding assembly: did you find the adafruit pcb to be less…"

ian commented on Reto's blog post Xbee socket board
"jordi: Can you say what you do not like about them? I have neither, but since my uC is already at 3.3V (not an arduino), I don't need the level converter on the Adafruit board, I guess the the leds might be helpful though. On the Sparkfun site it…"

"The elphel camera is open source, cheaper than the Axis stuff, has several compression schemes, can stream via WiFi to an open web client they provide, and is capable of capturing 30fps at 1920x1088. Up to 8 SD cards can be used for offline storage…"

I've met one guy using TI chips for home automation networking, but his application was low range and low bit…"

"Hi Jose and all
Your project is nice. I am working on a very similar project with http://diydrones.com/profile/ViperUAVTricopter
ViperUAVTricopter is the main force behind the project though
we have six rotors too, and our own remote design, but use…"

"Since it is sold out - when will you be supplying more of these boards to sparkfun? Thanks"

ian commented on ian's blog post Math models for inertial navigation and selection of a microcontroller
"Thanks for the comments, they were very helpful - I think I will give the LPC21xx a try. They're only $5-$10 more than the ATMegas an PIC's but offer much more wiggle room. This cost difference seems minor given the expense of airframe, sensors,…"

I am trying to decide on a platform, but I would like to consider the math model being used, an the whether there is a need for floating point on the microcontroller.There are several models available for inertial measurements - some handling drop…

"@Chris: I have no familiarity with Ning. I suppose a Wikipedia page might work.
I have a rather scattered text file I should go through, but off the top of my head:

"@Chris: Thanks, I had not seen this post, it is very helpful. A wiki page that lists the different projects as you have may be helpful for others to contribute - perhaps with features an degree of completion(?). Where would be an appropriate place…"

"Hi, not sure if this is appropriate place to post this (?).

But, have you experieced problems with the limited speed/memory of the arduino platform? I am looking to experiment with UAV's (either fixed wing or a quadrotor) an have been considering…"
