Neopixel TRINKET heater Mitten

This project is submitted for

  • The Trinket Everyday Carry Contest

This project was created on 12/17/2014 and last updated 10 years ago.

Description

I decided to look into this project because I seem to have bad circulation in my hands and walking to school (about 20 min walk) causes me to loose sensation in my fingers on cold days (around freezing and bellow). I live in Michigan and it gets cold here sometimes, so mittens in general don't totally prevent it. I had a spool of Nichrome wire laying around a decided to give this a try.



The project is powered from a 3.7V 1000mAH Lipo battery. Status and info is displayed on a 16 LED Adafruit Neo-pixel ring. The user will be able to adjust the heat with two tactile buttons. The 3V3 ATmega328P version of the Adafruit Trinket will be used to control everything. The Nichrome wire will be controlled with a PWM from the Trinket.


I am designing the circuit in KICAD, taking notes in emacs org-mode, and the project files are hosted on github.

Components

  • 1 × Trinket 3V3 ATmega328P
  • 1 × Nichrome Wire Heating element
  • 1 × NeoPixel Ring 16 addressable LEDs
  • 1 × Li-po Battery 3.7V 1000mAH

  • Finished BOM

    Jesse Millwood • 12/19/2014 at 11:03 • 0 comments

    I finished the BOM up today with some functionality built into kicad. As I design a project I associate part numbers with the symbols in the the schematic so making a BOM is easier later. I also sent my gerbers to 4pcb.com so if that goes well this morning, I will hopefully order my parts and board.

  • PCB Layout Done

    I finished a rough pcb layout. It could be a little more compact and organized better but I would really like to get this out to fab soon.

  • Schematic Done
