So I build this simple LED Tower with a few color changing LED's too.
Step 1: Gather Parts
a bunch of 1K ohm resistors
a bunch of LED's
a blank circuit board
a soldering iron
a 9v battery clip (use and old 9v battery if you don't have a battery clip.)
a 9v battery
Step 2: How to Solder
Solder one side of the 1K resistors to the positive side of the LED's
Now Solder all of the other side of the 1K resistor together.
