UV leds mosquito trap, chemical free

thingiverse

This device lures mosquitoes thanks to UV light emitted by UV LEDs, irresistible to these insects. The mosquitoes then get caught in the descending air flow created by a very quiet Arctic fan, and they finally dry out due to dehydration. No chemicals are involved, no noise is made, making it an ideal device for peaceful nights and stingless outdoor dining experiences. You'll need: - Twelve 5mm diameter UV LEDs - Four 100 ohm resistors - One 12V 120mm Arctic fan ARCTIC F12 Silent (available on Amazon for approximately $7 per unit) - One 12V power supply - One small switch - One power socket - A piece of mosquito screen I've mounted in parallel four groups of three LEDs, each group with one 100 ohm resistor so that if one LED burns out, the other groups won't be affected.
