HINT: start your soldering iron and hot glue gun now so they warm up
Step 1: What you will need
- some ultraviolet LEDs, I used 4
-A small switch
-One resistor for each LED, Mine were 330 ohm
-Black tape/ Electrical tape
-Small plastic or glass container, This should be watertight and clear
-A battery, Mine was a 7.2 volt RC car battery
-Wire cutters/ strippers
-Hot glue gun with hot glue
I had some stuff but I had to buy the LEDs ($2 Each) and the switch ($1 for a pack of 5)
Step 2: WARNING
"This LED produces intense ultraviolet light. Exposure to UV radiation can be harmful. Protect your eyes and skin when operating. Never look directly at the LED. Buyer assumes all risks using this LED."
Just so you know and don't try and hold me responsible either.
Step 3: Soldering part 1
Then wrap them in electrical tape.
Step 4: Soldering part 2
And solder your anodes together on the other side of the resistor.
then solder a wire onto each and wrap in electrical tape.
Step 5: Solder on the switch (part 3 of soldering)
And just in case you haven't caught on wrap your connections in electrical tape
I used a momentary switch because UV lights are dangerous and I would not want it to accidentally turn on and stay on.
