ZK-4KX power supply enclosure with automated fan

A bench power supply built around the cheap ZK-4KX buck-boost panel module (IN 5–30 V, OUT 0.5–30 V, datasheet), with a 3D-printed case and a small add-on board that runs a cooling fan only when the module gets warm, faster as it gets hotter. Everything runs from the same DC input (9 V / 2 A adapter tested, up to ~28 V supported).

- Single-sided PCB, 90 × 66 mm, designed for home etching (toner transfer, no vias, no jumpers) — Gerbers included if you'd rather order it. - Through-hole parts only: LM35, LM358, LM317, 78L05, one trimmer. - Fan off below a start temperature you set with the…
