Halloween LED Jellyfish Costume

Step 3 Mount the LED ropes to the basin

I got a translucent (this is important, so light glows through it) basin from a pound shop (dollar store). it was about 50cm diameter, which is an ok size. for 18 tentacles.

I used hot glue to mount the battery end of the lights to the inside of the basin.
Use sandpaper to rough the surfaces first, then clean them thoroughly so it sticks better. people WILL pull your tentacles.

Leaving 5cm of plastic tube inside the basin. This will let you use a cable tie around this soft bit of the rope and leave everything nice and secure.

Can you please help me with details on doing the electrical connections. I'm not very good at this...

Pedaleo, I think I can help you. Just connect all the bottom terminals of the LED ropes with wires together then repeat with the top ones. The two end terminals go as follows: one goes to the switch and the other goes to the battery pack. Do not use a pushbutton switch.

hi pedaleo - can you be more specific? the wiring up of the jellyfish is fiddly and time-consuming, but the electronics behind it is very simple - all the lights are re-wired in paralell - if you aren't sure what this means I think you should probably find someone who can explain in person, as it's quite a lot to explain over the internet....!

I absolutely love this idea. :) Any idea how long the batteries in those necklaces last? I'm trying to decide if I just want to risk using batteries alone... I would probably just use it for Halloween, so would just need it for one night. Thanks!

I think you would get away with it for 6 hours or so?! ant

Ok i hooded everything up right. But the batteries seem to get very hot.
