About Me:
Born 1971, been doing FF and RC planes since the late 1970's. My hobbies pretty much are AutoCAD, R/C plane design and construction, electronics design and construction related to RC applications, especially autopilots for very small UAVs.

"I see your points and concur. My AttoPilot (2007 Beta testing, sales 2008-2011) used the 8-core Propeller 32 bit IC. The IMU version 3.0 used 2 Propeller IC (16 cores). Focus was on fast optimized loops running on their own physical cores, with…"
"Hi, I'm still alive and breathing! Doing more work than ever on "Atto" stuff. I didn't intend the video on V4 for wide audience so I took it off the Vimeo sit this morning. The V4 proto is at level of board + 1 mile of wires and just recently etched…"
"Atto gets around wind estimation with a trick I think is clever and has some other advantages, but no I absolutely didn't mean any sarcasm. I mean that if your crab angle is 45 degrees, then obviously the wind speed must be about equal to aircraft…"
"AttoPilot doesn't have a wind estimator. I am tickled to read about people doing this."
"NOT SARCASM!!"
""I land at a bearing almost 45 degrees from where I'm pointing."
Yep, based on this I can easily see the winds must have been 28+mph."

"How did you measure the 28+ mph wind? No disrespect intended, but the grass wasn't moving all that much so I feel the need to ask. I once flew in ground-measured 25mph with gusts to 50 mph and it was very scary for a 3.3 Lb flying wing:…"
"In an attempt to inject a new thought, here is a partial idea based on what is used in some very sensitive lithography equipment in semiconductor processing: heavy mass. Not maybe something practical in a UAV where mass is a premium. The idea is…"
"How would viscoelsatic sorbothane be an better than mattress-type visco elastic foam in terms of trapping heat or moisture? Their both so similar."
"Static safe? Since I started using viscoelastic foam a couple years ago, I never ever let it touch electronics directly. There is no reason to think that foam made for matresses is treated to dissipate static."
"Rear prop is not needed at all if only they 1) counter rotate the wing props, 2) when swivelled up align those two props with the CG, 3) and have not only down/up angle control, but in/out as well. They are not taking advantage of propeller inertial…"
"Bozak - you got to filter for the speaker and understand. His persepctive is black-ops cold war nonsense. Most regular people think UAVs are just soooo advanced and other nonsense, such that "real" UAVs are products of secret development programs.…"
"Jack wrote "non standard gyros"
ADXRS610 is pretty standard, no?"

""and the PCB layout itself is hobby-grade (no effort to extend the ground planes to fill all available space, which is the trick good designers use to cut down on RF noise). "
Not necessarily true. You don't always knee-jerk fill open areas with…"

"Chris Anderson: My understanding is that the Eagle Tree systems already work on I2C bus."
"I have sold and shipped several (8) to Australia. I just need answers to a list of questions to start processing an export application, and the fee for that. There have been some problems with the webmail to the AttoPilot site (which is being…"
