I made a Jellyfish lamp by myself.
It is printed with fluorescent PLA and glows in the dark.
Inside the head is space for 6x LEDs
and the bottompart is wide enough to put 3x LEDs in.
The whole thing has 3 parts and is glued together.
The base is made out of glazed wood, but there is also a 3D file for it.
9x 3mm LEDs 3,2V 30mA
3x resistor 82 ohms
1x 230V AC to 12V DC transistor
