The part that caught me off guard is that the innards of this lamp are built out of circuit boards doing structural duty. made by morten stacked repeating LED_STICK carrier boards into a spine and added slotted LED_DISC boards as perpendicular baffles, then slid the whole assembly into a frosted plexiglass tube. Using the electronics as the skeleton is a bold way to build a floor-standing cylinder, and the payoff shows: the finished lamps cast segmented light disc patterns up the column instead of one continuous blur.
The build itself is thorough. The schematic was drawn in KiCad, with a circular base board carrying an ESP32-WROOM-32D and an LM1117 3.3V regulator. The base also has four capacitive touch pads silkscreened as ON, MODE, and BRIGHTNESS, which is a clean look for a lamp you adjust by feel. Inside, white 60 LED/m addressable strips sit behind the frosted tube, with spacer discs between each LED to keep the lit sections distinct. The tube measures 60 mm outside, 54 mm inside, with a 3 mm wall. White 3D-printed collars hold the base and a printed cap finishes the top.
The sound-reactive side runs off a blue microphone breakout board, and the lamp accepts custom Arduino code or WLED firmware, so it works with tooling many people already know. Power comes in through a 5V barrel jack, with supply options sized for the 1-meter and 2-meter versions.
One honest wrinkle: a bodge wire had to be added to fix an analog-to-digital converter pin assignment that clashed with Wi-Fi operation. That kind of revision is familiar to anyone who has routed a board late at night, and it does not detract from a tidy result. The soldered harness wires were even secured with adhesive epoxy, and a PCB ruler served as a 90-degree square during assembly.
