Guy McCaldin's Discussions

Disappointing customer service. Slow order fulfillment, wrong item sent, 3DR wants me to pay to resolve the issue.

Started this discussion. Last reply by Daniel Estes Jul 6, 2014. 15 Replies

I recently placed an order via the 3DR store, and was pretty disappointed with how it was handled.  One of the items was backordered, so I contacted customer service and asked for an estimated…Continue

"Sampling a 4kHz signal at 8kHz will resolve issues with aliasing, but you also need to consider how MEMs devices actually work. There’s a harmonic response at a hardware level that can distort measurements in a way that can’t easily or…"

"For extended endurance applications, a big component will be the TBO (Time Between Overhaul) of the internal combustion engine.  I work with sUAS in conservation applications, and I think this product could potentially bridge significant…"

Guy McCaldin commented on Chris Anderson's blog post How do modern open source autopilots compare to aerospace-grade IMUs?
"Aerospace grade, implying AS9100 certification or equivalent, doesn't relate to maximum performance.  It relates to verified reliability.   There's nothing stopping Drotek doing the work necessary for Pixhawk 3 to receive…"

Guy McCaldin commented on Hugues's blog post How does precision GPS work ( DGNSS , RTK , SBAS , PPP ) ?
"Generally good information, but there's a few discrepancies. For example, PPP isn't necessarily a paid service. Many receivers (including the ublox M8P) have a PPP mode that will produce an accurate position solution without commercial…"

Guy McCaldin commented on Martin Rüedi's blog post Synthetic camera offers FPV purely as a software solution
"It's an interesting concept that will definitely find a few applications.  I have some constructive feedback based on my personal experience and understanding. For hobby FPV, the whole point of flying a drone instead of using a simulation…"

"@Dmitriy, I'm not sure I understand your comments on dual frequency GPS systems having a faster initialisation times, or comparable accuracy to single frequency systems for PPP solutions.   For dual frequency commercial units (L1/L2) from…"

Guy McCaldin commented on Julian's blog post 3DR's Rise and Fall
"@Jesus While I see what you're saying, and certainly agree that it was 3DR's right to do whatever it wanted, my feedback here is motivated by a desire to have seen them succeed, and frustration at some of the decisions made which in my…"

Guy McCaldin commented on Julian's blog post 3DR's Rise and Fall
"To add to that sentiment: It wasn't just the hobby market, it also included customers like NASA, Universities, researchers, small businesses, and startups.  If DJI couldn't do what you needed, 3DR and Ardupilot was the obvious choice.…"

Guy McCaldin commented on Julian's blog post 3DR's Rise and Fall
"They're going up against Drone Deploy, Airware, Precision Hawk, and Propeller, who are years ahead in terms of development, and haven't wasted their VC funding on failed ventures.  Additionally, they've abandoned the ArduPilot…"

Guy McCaldin commented on Julian's blog post 3DR's Rise and Fall
"Seems 3DR pulled a Makerbot, despite having an opportunity to learn from Makerbot's mistakes (i.e. alienating most of their established market, over-expansion due to VC pressures, and rushing/underestimating product development). With respect…"
