Custom parts and enclosures

Shell enclosure – in progress
This one fits the electronics, but is too tall/wide. Also, need to figure out a way to keep it closed. I want to cast it in metal, which will require insulation but should provide enough weight to close the shell.

Code

HapticLily.inoC/C++
/*
  Blink
  Turns on an LED on for one second, then off for one second, repeatedly.

  Most Arduinos have an on-board LED you can control. On the Uno and
  Leonardo, it is attached to digital pin 13. If you're unsure what
  pin the on-board LED is connected to on your Arduino model, check
  the documentation at http://arduino.cc

  This example code is in the public domain.

// the setup function runs once when you press reset or power the board
void setup() {
  // initialize digital pin 13 as an output.
  pinMode(13, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
  digitalWrite(3, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(250);              // wait for .25 seconds
  digitalWrite(3, LOW);    // turn the LED off by making the voltage LOW
  delay(300000);              // wait for 5 minutes
}
