Figure 1
The device is made of blue LEDs and acrylic plexiglass to create a fancy raindrop lamp.
During the construction of the circuit, a wooden piece is cut off to 2×4 size where a hole is cut through it. A raindrop shape is sketched out around the hole with the use of a scroll saw. The shape will be finalized using a belt or disc sander. The pilot holes will be later drilled in the face for the attachment of acrylic in order to prevent crack on the wood when setting the screws.
In making the acrylic plexiglass face, a paper template may be used for pre-drilling the holes. The screws are sitting beneath the surface while countersinking into the plexiglass scrap. The plexiglass will then be attached to the wooden raindrop using 3 screws. The front and back will be sanded to slightly diffuse the LEDs.
The LEDs and resistors are soldered in the desired shape for the first PCB. The second PCB will be drilled with a hole for the power cord to pass through. The power cord will be soldered to the LED board and the two PCBs are attached with standoffs.

2 years ago: please send me the circuit diagram
2 years ago: the design of the circuit is very cute! maybe making it smaller and making more of them then putting them on the wall would be more attracting!
