eye rainbow box flashlight
For this assignment, I was tasked to create a flashlight defined as portable, battery-powered, and creates light. My first thought was that I wanted to work with things that I already had in hands and create something that could be used as a wearable. So, the only thing I had to buy for this assignment was a 9V battery.
Materials
- 9V battery;
- Arduino Nano (I had to use an Arduino because the light that I had was an addressable LED, which only works connected to a microcontroller – the good thing about it is that you can change the LED effect whenever you feel like – just need to modify the code).
- Flora RGB Smart NeoPixel programmed with a rainbow effect;
- 3D printed box (Base model downloaded from Thingverse, designed by anewsome, and customized by myself using the Tinkercad software);
- Satin keychain;
- Wires;
- Reflective fabric to customize the eyes;
- Small breadboard;
- Velcro strip.
Machines/Tools
- 3D printer Ultimaker 2+;
- Drill (to create a tiny hole in the box to pass wires through);
- Solder;
- Scissor;
- Wirecutter;
- Hot glue gun.
Reminders
- Do not try to use hot glue with wires;
- It’s always better to have more work building a switch instead of dealing with wires every time you want to turn on your device;
- Be delicate when working with 3d printed small objects. Always be delicate in dealing with small materials.
My final object turned out to be a potential necklace or a luminary that can be hanged anywhere.
