Illuminated Cave Project – Part 4

Now it’s time to get the electronics integrated into the box. I first got the resistor soldered to the positive lead of the LED and then connected both positive and negative leads to two small diameter 3 foot wires. Then I finished it off with some heat-shrink to insulate everything. Finally I arranged the lights to illuminate the formations the best.

Materials used:

  • white LEDs (18x)
  • 220 Om resistors (18x)
  • wire (18x)
  • solder
  • soldering iron
  • helping hand
