  • FAA registration?

    jeff • 12/15/2015 at 02:44 • 0 comments

    fully assembled with battery, the device weighs 23.5 grams.

    making it exempt from the FAA's new registration requirements.

when you design your own flight controller with an ARM 32bit MCU how do you make the firmware and software? isn't that more difficult or do you copy opensource information

thanks

  Are you sure? yes | no

alexbhandari wrote 04/14/2016 at 00:36 • point

It looks like the board is three layers. There is a single trace on the middle layer. Was space so tight that you needed an extra layer just for that trace?

  Are you sure? yes | no

jeff wrote 04/14/2016 at 16:20 • point

it is actually 4 layers. the layers without traces are ground and vcc.

any component that needs to connect to gnd or vcc has a short trace on the top layer to a via which connects to it to the gnd or vcc plane.

What motors are you using?

jeff wrote 12/27/2015 at 18:21 • point

hobbyking "0716". replacement parts for some sort of quad that they no longer sell.

Hey Jeff,

how can you control, give orders to the copter?

  Are you sure? yes | no

jeff wrote 12/25/2015 at 05:08 • point

I don't give it orders.

it is autonomous, it crashes into things of its own free-will.

  Are you sure? yes | no

x-labz wrote 12/25/2015 at 15:23 • point

cool :) 

...but do You plan to add some short of senses to this poor little blind copter? infrared or UH? 

...or by adding propeller cover/protector, it could survive the bumps, and even the CPU could recognize this collisions by analyzing the IMU data

anyway good luck with the project!

  Are you sure? yes | no

jeff wrote 12/25/2015 at 21:11 • point

I've used IR on other robotics projects, and wanted to here. the microcontroller has plenty of unused pins, but no room in one inch. next version, perhaps.

it is easy to detect bumps+crashes with the accelerometer, but I don't have a recovery algorithm better than "turn off motors", yet.

  Are you sure? yes | no

guybthe wrote 12/05/2015 at 18:46 • point

I know the goal is to do a 1 inch project, however would your control board work w/ larger scale drone / props / motors assuming more energy storage and step up for the larger motors? Very interested in this as a lightweight controller.

  Are you sure? yes | no

jeff wrote 12/06/2015 at 21:40 • point

the motor drivers won't handle too much more, they'd need to be beefed up,

and possibly the voltage regulator, if you want a higher voltage.

but the rest of the ckt should be fine.

  Are you sure? yes | no

Could you do a short post on the PCB, code, and other things involved in flight control?

  Are you sure? yes | no

jeff wrote 11/10/2015 at 01:12 • point

I just updated the github with the schematic, board, and cad files. I'm still working on the code.

did you have questions?

  Are you sure? yes | no

Albert Latham wrote 11/10/2015 at 01:22 • point

I saw that the control board has an STM chip which made me immediately think of Paparazzi. Is your code Paparazzi based?

  Are you sure? yes | no

jeff wrote 11/10/2015 at 04:48 • point

no, not based on anything

  Are you sure? yes | no

Albert Latham wrote 11/10/2015 at 04:58 • point

Look into Paparazzi. The code is very mature and is compatible with your main processor. You could potentially save a lot of development time by using it. (I'm biased as I worked with a system that was Paparazzi driven.)

  Are you sure? yes | no

Ivoah wrote 10/09/2015 at 00:32 • point

Why are the rotors tilted inwards? Does it help with stability?

  Are you sure? yes | no

jeff wrote 10/09/2015 at 19:03 • point

yes,  it improves the stability.   google the word "dihedral", if you are interested.

(but disclaimer:  I am not an aeronautical engineer)

  Are you sure? yes | no
