Circuit sculpture

Free-form brass soldering is hard. Working in two dimensions is hard enough, but when you add a Z axis, you suddenly need two hands to hold your workpiece plus another two to hold the solder and the iron. And even when you’ve managed that step, you still have to come up with a working circuit. That’s why we’re fascinated by this lamp from Edward Agombar.

It’s powered by USB-C and uses four WS2812B LEDs to create a soft glow. There’s a Seeeduino XIAO controlling the circuit, and a voltage booster to bring the 3.3 V output by the XIAO up to the 5 V needed by the LEDs.
