Prototyping a Spray Painting Quadcopter at NEWINC

This guide follows an attempt to make a spray painting quadcopter for indoor drone painting.

It is a series of experiments and observations, not quite a perfect step-by-step tutorial! =D

Use this guide on your own property only! I do not endorse the use of this technology for any illegal painting.

This guide was developed with support from NEWINC, Deep Lab, and 3D Robotics, and through collaboration with Dan Moore and KATSU.

This project has many parts and optional components.

For the sprayer device:

For the plug-and-play power circuit:

General quadcopter stuff:

  • 3D printed prop guards (now updated for IRIS+)
  • extra propellers
  • spray paint with straw from cleaning spray bottle
  • stiff wire for mounting sprayer – we found that tomato cages work great

Buzzing Mindfulness Bracelet with GEMMA

Build yourself a buzzing bracelet for subtle haptic feedback as time passes! It’s great for reminding yourself to get up and walk away from your desk for a few minutes each hour, or just as a way to have a new awareness of how the perception of passing time varies based on what you’re doing.

You’ll whip up a vibrating motor circuit using a transistor, resistor, and diode, and use GEMMA to control the frequency of vibration in between low-power microcontroller naps. The circuit lives inside a linked leather/rubber bracelet, but you could build it into whatever you please. This project involves some precision soldering, but is otherwise quite easy!

Before you begin, make sure you’ve read the following prerequisite guides:

For this project, you will need:
