Airsoft Booby Trap

Airsoft Booby Trap Place it anywhere you want, arm it and done. If anyone moves in front of the trap, it will trigger, red&white LEDs flashing rapidly and buzzing loudly. Enemy neutralized. But if spotted early enough, it can be disabled. Simply get some BBs into the opening over the movement detector and the red lights will blink three times, indicating it's safe to move again. Print Settings Printer: Vellemann K8200 Rafts: No Supports: No Resolution: 0.25mm/layer Infill: 30% Operating When you turn on the trap, the blue button flashes three times followed by a short break. This will continue until you press the blue button. Now the trap is arming, the button blinks for 10 seconds and then stays on until no movement is detected. When the blue light goes off, the trap is fully armed. If anyone walks by the front of the trap, red&white LEDs flash rapidly and the trap buzzes loudly. This means the person has been hit. After that, the blue light continues blinking, indicating the trap has been triggered. If the trap wasn't triggered and someone fires some BBs into the opening, the red LEDs will blink three times, indicating the trap is disabled and it's safe to walk by. The blue button flashes three times followed by a break, and so on... You can rearm the trap by pressing the blue button again. Don't forget to remove the BBs from the funnel if the trap was disabled. BOM & Soldering The layout is done for a standard 2.54mm breadboard. No need to build a PCB.
