General:
-These 3D printed parts
-Battery pack (I used a total of 5 AAs wired together)
-Battery cable
-Elastic strap and safety pins
For less-complicated electronics:
-28 blue LEDs
-resistors to limit current (such as 14 50 ohm resistors - 2 LEDs per resistor, or there are
other configurations)
For more-complicated electronics:
-28 blue LEDs
-14 50 ohm resistors
-2 MOSFETs (one to control the bank of 16 outer LEDs, one for the middle bank of 8 - the
inner 4 were powered directly from the microcontroller)
-PIC16F629 microcontroller
-22 uF 16V capacitor on the input power
I am a firmware engineer, but my education is in mechanical engineering. I particularly like to work on projects that involve electronics, firmware, and mechanical hardware. And cupcakes.
