Sure thing. I’d start with a small pressure pad under the lure—just enough to register a pigeon’s footfall. The pad would feed a low‑power microcontroller that runs a 12‑volt spring‑loaded trap. All the electronics stay hidden in the lure, and the trap only releases when the pad detects a weight above a set threshold. It’s silent, cheap to build, and you can program the delay so the pigeon doesn’t notice it coming. Just make sure the lure looks natural; pigeons aren’t exactly fooled by anything that looks like a snack. Let me know if you want a schematic or a component list.

Here’s a quick rundown of what you’ll need: 3.3 V microcontroller (ATtiny85 or similar), a lightweight piezo or force‑sensing resistor for the pressure pad, a 12 V relay or MOSFET switch, a 12 V spring‑loaded latch or small solenoid to pull the trap, a 12 V battery or two 1.5 V cells in series, a few 10 kΩ pull‑up resistors, a small capacitor for power smoothing, and a tiny PCB or perfboard to mount it all. Add a little enclosure or potting compound so the electronics stay hidden under the seed‑looking lure. That’s the core kit – tweak the delay circuit with a simple RC timer or code on the ATtiny.

Got it—I'll keep the enclosure light, maybe a thin 1 mm polycarbonate or just epoxy‑potting over the PCB. The relay circuit will be a quick‑fire 12 V MOSFET switch; the ATtiny will pull it up in 300 ms max. I'll build a mock‑up today and drop the prototype by tomorrow. Looking forward to your quiet observation test.
