sky laser / beam light / mobile laser in the sky

High-power green laser module (520 nm, 3 W, 12 V) Mark your party or event from kilometers away with a high-power green laser that consumes as little power as a laptop. As shown in the photos, I built a protective enclosure for the laser and then integrated a microwave oven motor along with a timer relay, enabling continuous on/off cycling of the motor as long as it remains connected to electricity. Thus, the laser rotates across the sky, creating a more dynamic and entertaining effect than if it were stationary. The laser unit alone—including the included binoculars—cost €352; adding customs duties, CTT shipping fees, and the other components described and shown in the photos brings the total cost to over €500. The laser already incorporates a built-in cooling fan that runs continuously, allowing the laser to operate without interruption. I am now selling it well below its original price, especially since it is practically new—having been used for only three nights during last summer’s festivals.
