Step 1: Materials
-A two pack of green LEDs (part number 276-304)
-a SPST (single pole, single throw) toggle switch (part number 275-612)
-a 10 ohm resistor. I just had this lying around.
-3 AA batteries
-a 5K audiotaper Potentiometer (part number 271-1720)
-random pieces of wire that I had lying around.
-an "aquired" sign.
-a soldering iron
Step 2: Drilling
Step 3: Making the battery pack
This is simple, just solder the "+" end of the battery to the "-" end of the other. It should be labeled on the battery which end is which, but if not, the flat end is the negative side, and the side with the little bump is the positive end.
