About Me:
I'm an Mechanical Engineer who works a manufacturing process engineer. I've loved everything that flies since I was old enough to look up.
Please tell us a bit about your UAV interest
Building from scratch a Quadcopter and incorporating absolute inertial position tracking.

"I hang out in Plymouth area and am also a mechanical engineer.
Joop's code is great for learning some of the basic concepts of level flight, but it it not a good place to start if you actually want to make something fly well.

"A couple of tips:
Gyro integration speed is critical to stability (400Hz is reasonable for an 8bit micro). Drift correction can happen at a slower rate to save computation time (~100Hz).
You have to translate Mag, and Accel readings from…"

"If it wasn't for the move to NY, I'd be all over this."
"5-20ms delay is huge. You should be under 1ms. Racing quads start their esc pulses less than 10us after the values are computed. Most quads out today are sending motor speed updates at a rate of 400 to 4000 times per second (and higher). It…"
"I can't watch the video at the moment, so I may be able to add mroe later.
As long as the motors each carry roughly the same load, that should not be the problem. Weight does not add stability to a quad. Best stability is acheived when moment of…"

"My drone inspired by your build:
I designed my own 3D printed frame because I enjoy re-inventing wheels...
Motors are RCX 1304 3200kV. I used the same props, esc and flight controller as you. The receiver is an Orange Rx (Spektrum) satillite.…"

"ok, I had estimated your flying weight too high. Dropping it to 150g shows hover at 60% throttle. Thanks."
"Do you have a guess as to where you throttle is at hover? I ask as simulations show that a 2s battery with that motor and prop may hover at ~80% throttle. Even with the added weight, 3s and 4s batteries show throttle at hoover much closer to 50%.…"
"Very cool... I really need to get back to work on my bare bones quad control software. It functions well already but needs some cleaning up before I put it on my github. And now I want build a little quad like."
"Nice build... now I want one.
I assume this will be coming in a future post, but any hints on what you are changing in your version of Base/CleanFlight?"

"Thank for taking the effort to upload the magnetometer document. Was thinking of trying to adapt your alignment method to my IMU.

It might be a language thing, but this sounds like a bad idea. Maybe a picture?"

"Ok, that seems about right on the speed front. So if a person wanted to overclock to 96Mhz, there is another 30%+ more performance to be had.
Just looked up the Nucleo boards. That is an amazing amount of power for $10. Physically larger than…"
