Instructions | UV water purifier

1

electric circuit

Instead of using a real UV light for the project we decided to use blue LED's for our project. The wires are connected to the LED's and connected to the dynamo through a USB cable. We used four 500 ohm resistors in our circuit as you can see.

waterproof

We build a drawstring to make the circuit waterproof and a part of the USB cable.

UV light

Now you have to take the circuit with the LEDS and insert them on the plastic bag. The USB cable is power up by an external battery ( 5V)

Finally the plug part

We had to cut a piece of forex on the top of the device. We cut a small piece to be our plug. Then we glue the top and the bottom of our device.
5

the dynamo issue

Our dynamo was broke so we just took the motor and the storage unit and build our own dynamo to power up the device
