I was walking through my local camping supply store the other day when I came across this water purifier that cost $50 (I know outrageous) Being the DIYer I am I took a closer look at it to find that it was simply Some UV lights. Then it hit me, I can make this way cheaper. So I did.
HINT: start your soldering iron and hot glue gun now so they warm up
Step 1: What you will need
Here is a list of all the tools and parts 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)
