Arc Reactor Mark I

thingiverse

This year I wanted to make a costume that was a bit more unique and still fit my subtle personality. So, I decided to create a Tony Stark costume! There are lots of Iron Man costumes out there, all very well done, but I haven't seen many Tony Stark costumes around. So, here it is, my Arc Reactor, controlled by my phone via Bluetooth. I wrote a simple program to change colors using an app on my phone to switch through them. Design: I had seen other Arc Reactor prints in multiple pieces and requiring assembly. I didn't want to do that with mine; I like things simple, so I designed a one-piece Arc Reactor in Autodesk Inventor and painted it with some low-cost paint from Walmart. It prints flat, rotate it 90 degrees so it's lying down on the printer bed, and print with no support material. I like to design things to avoid support material when possible. I printed it using clear PLA, 1.75mm clear plastic. With clear plastic, it's essential to print at 100% infill so the light diffuses properly. Electrical: Arduino is amazing! I used a Bluno Beetle and programmed it with the Arduino IDE. For the LED lights, I used two generic neopixel rings: a 12-Pixel RGB LED ring for the outer lights and a 7-Pixel RGB LED ring for the inner core lights. It's all powered by a cheap power bank, outputting 5 volts. Programming: Here is the code I wrote using the NeoPixel Library. #include <Adafruit_NeoPixel.h> #define strip_pin A2 #define strip2_pin A1 #define strip_count 7 #define strip2_count 16 Adafruit_NeoPixel strip = Adafruit_NeoPixel(strip_count, strip_pin, NEO_RGB + NEO_KHZ800); Adafruit_NeoPixel strip2 = Adafruit_NeoPixel(strip2_count, strip2_pin, NEO_RGB + NEO_KHZ800); int neo_delay (500); int showType = 0; char switch_show; int done = 0; void neo_setup() { strip.begin(); strip2.begin(); for(int i=0;i<strip_count;i++) { strip.setPixelColor(i, strip.Color(150,150,150)); strip.show(); delay(1); } for(int i=0;i<strip2_count;i++) { strip2.setPixelColor(i, strip2.Color(150,150,150)); strip2.show(); delay(1); } } void setup() { Serial.begin(115200); neo_setup(); } void loop() { if (Serial.available()) { switch_show = Serial.read();// add it to the inputString: Serial.println(switch_show); cycle_show(); } } void cycle_show() { switch (switch_show) { case 'a': done = 0; colors(0,0,0); colors1(0,0,0); break; case 'b': colors(0,0,150); break; case 'c': colors(255,255,255); break; case 'd': colors(255,255,255); delay(200); colors(0,0,0); break; case 'e': colors(0,0,0); delay(10); colors1(0,255,0); break; } } void colors (int a, int b, int c){ for(int i=0;i<strip_count;i++) { strip.setPixelColor(i, strip.Color(a,b,c)); strip.show(); delay(1); } for(int i=0;i<strip2_count;i++) { strip2.setPixelColor(i, strip2.Color(a,b,c)); strip2.show(); delay(1); } } void colors1 (int a, int b, int c){ for(int i=0;i<strip_count;i++) { strip.setPixelColor(i, strip.Color(a,b,c)); strip.show(); delay(1); } }
