"@Fab: Chill out dude, do you have a problem with success and people making money? Be thankful for what we have nowadays ... Before there was radioshack, tandy, heathkit, and other crap. Now we've got sparkfun, diydrones, adafruit,…"
"I'm a big fan of DIYDrones, as well as OpenPilot. Both are fantabulastic projects. I am a little worried though about the negative attitude of OpenPilot towards DIYDrones. They claim that DIYDrones used some of the design from OpenPilot (which is…"
"Thanks to those of you, both well-known and behind the scenes, who help make this community as vibrant and helpful it is!"
"Thanks for the protocol jason. Two questions:
1) How was the mtk3329 protocol changed? Is there a command to modify the protocol to NMEA string, customized binary, etc ... ? Do you have to have a relationship with MediaTek to do it, or is there a…"

"Is the data format of the 'custom DIY drones' GPS firmware available somewhere? I can infer it from the code, but I would like to see some documentation ..."
"Where is the documentation to interpret the binary messages the MT3329 is spitting out? The datasheet only includes the NMEA string output - not the 'compressed' binary data output."
"Jordi: Strap it onto a plank of wood with a motor and dump the data here please :)"
"Pete: I also went thru it rather quickly (at work .. bleh). One issue I saw with the MRAC scheme was that there is no guarantee of converging to a particular solution, rather - the the error is guaranteed to converge to zero. Perhaps this is the…"
"Ryan, thanks a bunch! Soooo .... anyone wanna implement MRAC D or L1 and try it out? Source code is given! I've been thinking about something like this for a while, some way to parameterize an airframe's dynamic response, and an adaptive way to…"
"What processor do you plan on using in the future? I am looking for a processor which has maximum native PWM capability. I haven't been able to find any processors which had that, and all the other connectivity options I would like - so I've been…"
"If you want to port the Ardupilot code or something similar, you should consider using something like these:
Maple:

This uses the stm32 arm7 processor. 90 MIPS! Is supposed to be an 'arduino' based on the stm32.…"

* 900 MHz Frequency Hopping Spread Spectrum Transceiver* Point-to-Point and Point-to-Multipoint Network Topologies* Transmitter Power Configurable from 1 mW to 1 W* RF Data Rate Configurable from 38.4 to 500 kb/s* Serial Port Rate up to 460.8 kb/s…
"Several people have done this ... though figuring out distances 360 deg around you, at a significant update rate may be something challenging.

"Hey Jordi, short of using the adxl gyros - which of the cheaper ones are least effected by vibration? ST Micro, Invensense?"
"Curt: No problem. I noticed there wasn't any code posted, so I referenced my post in which there is some bare-bones .C code which someone could use to go down this path :) . I must say, the tree structure thru which various simulation parameters are…"
"Thanks Curt for this wonderful tool. For those of you who are curious on how to get data in and out of flightgear, I wrote a blog post which details it here: http://www.diydrones.com/profiles/blogs/closed-loop-autopilot-1 . Included is also a C…"
