"I live in a valley and there are mountains they go 45 degrees up the horizon on one side. So I thought they'd be useless. And really, the IR is a crutch for everyone until they can get gyros working. But, after seeing some data Dean posted in the…"
"Take a look at these pieces for study as it's similar: http://www.rcgroups.com/forums/showthread.php?t=843174
I'm still working on it, but currently I ended last summer thwarted by two things. The first was gyro drift. Inside the cockpit of my…"

"This is really cool. It's kind of getting close to that hovering ball thing they used for light saber training in the first star wars.
If you could accurately squirt some starting fluid/ether into a thruster and spark it electronically, I wonder if…"

">>on some RC-forum i seen info, that 5HZ modules using real 1 Hz and extrapolation<<
All GPS tracks a ~10MHz chip stream to determine the relative timing of satellites. At any time, the hardware can tell you within a fraction of the chip time (~100…"

"There's no standard for part marking. You will only get a pin 1 designator. From there, you have to refer to the spec sheet. Your LED did have a pin 1 designator. You just don't know if pin is is anode or cathode :)
If you use a sot23 LED, you'll…"

"It'd be great if you guys could publish the noise characteristics of your SCP1000. Just measure 20 samples in a room with still air, then put them in excel and run the =stdev(A1:A20) function and report that.
I'm measuring a std dev of 7.12 counts,…"

"Jacob, i've not just had visions, I've seen it actually happen :)
I've used an altitimeter with a 200 mS sample rate (5X faster than GPS) and a standard deviation of 1.2 meters on each reading (probably 5X better than GPS) and an autopilot could…"

"If you hold a constant pitch and a constant RPM, aren't you assured that your airplane will always settle into a constant airspeed and sink rate, regardless of wind?"
"For something to be patented, on criterion is that it needs to be non-obvious to someone "skilled in the art". I'm not sure moving from absolute to relative markers is non-obvious."
"If you are 10,000 feet away from me and you send a blip at GPS t=0, then it takes about 10,000 nS, or 10 uS to arrive at my location. Seems like there would be several solutions to your equation above and it'd be impossible to disambiguate."
"Terraserver is pretty good, and doesn't have the heavy-handed terms of service that google and microsoft have. It also supports several web service interfaces and has always been very fast for me when using the webapp interfaces."
