[Nick Electronics] had an thought to construct a classy lamp that would remodel its form whereas lit. This aim was achieved superbly with assistance from many, many filament LEDs.
If you happen to’re unfamiliar with filament LEDs, they’re principally skinny plastic filaments filled with plenty of particular person LEDs which might be very shut collectively. This successfully creates a steady, versatile, glowing string that can be utilized for all kinds of inventive functions.
[Nick] packed the lights into an interlocking stack of PCBs that make up the lamp’s construction. Every PCB layer hosts 4 filaments mounted across the periphery, and has a pin that locks right into a groove within the subsequent layer to permit them to tug one another round as they flip. The PCBs rotate round a central shaft, with energy handed from one to the opposite through interlinking wires. Drive is through a stepper motor on high of the lamp, managed by an A4988 driver. There’s additionally an ATmega48 microcontroller onboard, which is the brains of the operation. A DC-DC converter onboard steps up the 5 V enter voltage from USB-C to 10 volts for the stepper motor.
It’s neat to look at the lamp in motion, glowing and slowly shifting in patterns because the layers catch and rotate out and in of alignment. We’ve seen attention-grabbing builds on this vein earlier than, like this unbelievable origami lamp from a couple of years in the past.
