During one of my regular daydreams, I was imagining what things I could make to be like Iron Man. In my mind, being like Iron Man means using wearables to do awesome things. Once Tony Stark escapes the terrorists, he goes about creating a new Iron Man suit with one of the first components being the gauntlet. Iron Man gauntlets appear many times throughout the movies with them being perhaps the most fundamental part of the Iron Man power armor. Since it isn't really possible to create the repulsors that the armor has, I thought about using a glove as a control interface.
The idea here is to make a glove that can be used to control some Neopixel LEDs. Each fingertip has a small gap between the conductive threads to create an open circuit. On the thumb is a small piece of conductive thread that is wide enough to close the circuit when I touch a fingertip with my thumb. In this way, the thumb stitch of thread works like a switch. By wiring all of this into a Flora, I can do a variety of magic with the Neopixels.
- Change which Neopixels are on
- Change the color of the Neopixels
- Trigger different lighting effects
- Blind my enemies (Just kidding, Neopixels are kind of bright, so this is semi-legit.)
In order to make the wiring simpler, my plan is to use the analog-to-digital input of an Adafruit Flora wearable microcontroller as the input of all the fingers. In the circuit of each finger is a resistor of different resistance. By doing this, each finger will generate a different specific voltage into the Flora's input. Since my wife and daughter are both out of town this week, this project is one I'll do some proof-of-concept work and then complete with my daughter.
