Step 2Component list

Here is what you need to make a LED cube:

  • 512x  LEDs (plus some extra for making mistakes!)
  • 64x resistors. (see separate step for ohm value)
  • 1x or 2x large prototype PCBs. The type with copper "eyes", see image.
  • 1x ATmega32 microcontroller (you can also use the pin-compatible ATmega16)
  • 3x status LEDs. You choose color and size.
  • 3x resistors for the status LEDs.
  • 8x 74HC574 ICs
  • 16x PN2222 transistors
  • 16x 1k resistors
  • 1x 74HC138 IC
  • 1x Maxim MAX232 IC
  • 1x 14.7456 MHz crustal
  • 2x 22pF ceramic capacitors
  • 16x 0.1uF ceramic capacitors
  • 3x 1000uF electrolytic capacitor
  • 3x 10uF electrolytic capacitor
  • 1x 100uF electrolytic capacitors
  • 8x 20 pin IC sockets
  • 1x 40 pin IC socket
  • 2x 16 pin IC socket
  • 1x 2-pin screw terminal
  • 1x 2wire cable with plugs
  • 9x 8-pin terminal pins
  • 1x 4-pin terminal pins, right angle
  • 2x 16-pin ribbon cable connector
  • 1x 10-pin ribbon cable connector
  • Ribbon cable
  • 2x pushbuttons
  • 2x ribbon cable plugs
  • 9x 8-pin female header plugs
  • Serial cable and 4pin female pin header
  • Piece of wood for template and base
  • 8x optional pull-up resistors for layers
  • 5v power supply (see separate step for power supply)
