Line dropper design.

Abhi Verma John Rodrigues Let’s start with the design of a line dropper thing.

It should be"complete" device, with its own power supply, and which can be attached to any ready-to-fly quadcopter. The reason for this is since the quadcopter will be used near and over water, it might drown. So the quadcopter + line dropper shouldn’t be heavy on the pocket. I am envisioning one which can be used on any <100 dollar quadcopter.

I’ve separated fishing line and camera controls from the flight radio controller so that this device can be used independently of the RC flight transmitter and receiver system.

I’ll refine and put everything down on paper, but here’s what I’m thinking right now.

  1. NRF transmitter and receiver pair with 2 channels to control fishing line (push button) and camera orientation (knob).
  2. Pull type solenoid to release fishing line.
  3. FPV mini camera.
  4. 5V Servo to change camera orientation between the front and bottom.
  5. Option for on-screen (OSD) display for the camera.
    We should connect and OSD module to the camera and keep an electrical connector on the body of the device to connect to any flight controller board.
  6. Lipo 2s UBEC to get 5V output for all of the above components.
  7. 3D printed enclosure to enclose all components of the device.

Have I made this too hard? BTW, I’m open to suggestions.

I’ll work on the electronics part of the dropper. What you guys think about adding Bluetooth or wifi to dropper. So instead of using nrf, we will not need a separate remote for this. This can be done using any smartphone.
My suggestion will be ESP WIFI. It also have two output pins.
