laser cat lamp

printed with sunlu silk copper filament and i fit it with white led a 220 ohm dropping resistor and a switch i simply soldered it to a small piece of board cut the end off a usb lead for connectivity and secured the small switch hot glued it in place.
it can be powered through any usb outlet even pc or laptop as the current drain is very low about 22mA i think.
it leaves beautiful shadow around it thanks to a great design.
