Step 1: Parts List
- PVC tube (1.5mm inner diameter 40cm total length)
- Green leds x8
- AAA battery holder x3
- Mini switch
- PVC end cap
- Epoxy glue
Step 2: Connecting the LEDs
First I cut the legs of the LEDs and soldered small piece of wires. Then I soldered 8 leds in parallel.
Step 3: Glueing the Battery Holders and Switch
After connecting the LEDs I glued three aaa battery holders in series with an epoxy glue. A switch was glued at the end of the battery holder. Finally I made the proper connections with soldering iron. I glued the switch to the drilled pvc end cap
Step 4: Inserting LEDs to the Pipe
Finally I lead through the leds inside the pipe. A little bit alcohol helped for lubrication. Later I put the batteries and sealed the upper end with some hot glue. I added waterproof switch cap on the switch. You can see its function underwater. A hook cam be attached to an end for a futher improvement.
