About Me:
I am a software engineer and mixed media artist. At the moment I am employed by SONOS as a member of the DSP team. Prior experience includes video games (Harmonix) and desktop music production (Cakewalk). I am a frequent contributor to the underground art community in Boston as a VJ, musician and designer of hardware for audio/visual art projects.
Please tell us a bit about your UAV interest
My goals with UAVs are to create an aerial video platform and to have the opportunity to get involved in software development for control of dynamic systems and robotics.

"I wonder if the context where any failures could happen (if in fact they are possible...?) is unplugging a battery *while current is drawn*, that is, while the motors are running. In this case there would be an inductive voltage spike, which the…"
"So copper tape would help with EMI that might affect the GPS or sonar wiring, but this will actually block static magnetic fields, got it. As far as the earth's magnetic field, while this will have some blocking effect, I based on application it…"
"how does this compare to, say, copper tape connected to ground?"
"Looking good! Yes, you are going to have to use the MinimOSD configuration tool to remove display elements that aren't actually used, like the RSSI, you should also tie unused inputs as Earl said. MinimOSD can also be used with planes, so I suppose…"
"Hmm, I think that your frame should teach us all the following lesson: Vibration control is everything. And because your frame is not super rigid (and has, apparently, a very high damping coefficient) it soaks up all the vibrations when compared to…"
"Old conversation I know, Twisted pairs would help a little with the power line, but not so much with the signal line. You would be better off with a shielded cable salvaged from a broken usb hub or microphone cable, etc.
I just solved my last…"

"Wow, I have been designing exactly this same mount in the last couple of days. A basic 2 axis mount for the go pro that holds the camera with an elastic. During my design I came to the hypothesis that a 2 axis mount like this would give inherently…"
"To anybody following this discussion, I have started work on an improved version of this algorithm. Namely, instead of leaking the velocity away, the velocity drift is controlled by fusing the low frequency component of sonar derived velocity…"
"Oh, another type of test is to "crawl" the quad on the floor. Use the pitch / roll and yaw controls to get the quad to slide on the ground (without actually taking off). You just have to watch the throttle and keep it low and steady. If your radio…"
"Just some warning: I tried doing some tests tethered, but the tether loads cause instability of their own. One type of test you should consider is the test while holding in your arms (very carefully!) to check if the quad "resists" your attempts at…"
Hi, I have been lurking for a while, but recently I got my quad up in the air on ardupirates, and just this week, I started getting successful flights with AC2. I am very impressed with the progress since early this year. Now, what is the yoyo…
"I have found that I can do PID tuning of the acro mode rates while in stable mode: with too much rate_P the quad will have very rapid short oscillations, or jitters (unlike the oscillations from having too much stab_P) for my taste I just lower Rate…"
"It always bothered me why barometer or sonar noise has to be a problem. I would think that accel Z can be integrated twice for a short term aproximation of altitude using leaky integrators. The result can be combined with low pass filtered altitude…"
"I am unable to find any stable PIDs with ACM... I had found values close to defaults that worked perfectly with ardupirates. My conclusion? smaller quads might be out of reach for the loop rate of ACM. I would be delighted to be proven wrong, since…"
"Any inertial state capable of taking the ball off the quad would also result in the quad no longer remaining stable and in the air. The quad's stability control works to maintain attitude, your inputs (or altitude control) work to keep it from…"
"Is the arducopter planned to send APM binary stream? I could not see this in the source code.
