Soldier Builds $120 Drone Detector to Save Lives

Army Sgt. Ryan Minton worried about his fellow soldiers facing a new kind of danger, so he did what any determined problem solver would do: he went to his basement and got to work.

Two years later, his invention is about to change battlefield safety. Minton created a wearable drone detector that alerts soldiers when unmanned aircraft are nearby, addressing what has become the deadliest threat in modern combat.

The device scans for radio signals from drones and can beep or vibrate when it detects one. Soldiers can wear it like protective gear, keeping their hands free and eyes on the mission instead of constantly scanning the sky.

Minton, a special projects engineer with the 2nd Cavalry Regiment's Innovation Cell in Vilseck, Germany, built the detector from parts available online. The total cost? Under $120 per unit, and each one takes less than an hour to put together.

"Not only do they have to look for security on the ground, but now they have to look for security in the sky as well," Minton said. "I'm trying to mitigate that gap and create a safe environment for soldiers."

The timing couldn't be more critical. Drones have caused up to 85% of all front-line casualties in the Russia-Ukraine war, according to the Council on Foreign Relations. These unmanned aircraft now target everything from infantry to infrastructure, transforming how wars are fought.

Minton's garage project caught the attention of his leadership, who moved him into the 7th Army Training Command's Design Innovation Research and Testing Lab. The facility launched this year specifically to connect soldiers, engineers, and researchers working on rapid battlefield solutions.

He developed multiple versions of the detector, including one that fits in a pocket with a single battery and larger models in a pouch with three batteries. One version focuses specifically on detecting the Wi-Fi signals used by first-person view drones common in Ukraine.

Minton even 3D-printed custom cases that make the bigger versions look like standard military radios. The detector heads to the Grafenwoehr Training Area in the coming weeks for field testing with actual troops.

The Ripple Effect

What started as one sergeant's basement project could protect soldiers across the entire U.S. Army. Maj. Lindsay McCue, who oversees Army innovation initiatives, said the detector represents exactly where the military needs to go: empowering troops to identify problems and create solutions themselves.

The low cost and simple assembly mean units could equip every soldier instead of rationing expensive equipment to a select few. NATO allies facing similar drone threats have also expressed interest in the technology.

McCue sees Minton's work as proof that innovation doesn't require massive budgets or years of development. Sometimes it just takes one person who cares enough to spend their nights building something better.

One soldier's determination to protect his teammates might just save thousands of lives.
