We’ve all seen this in movies: Spies and private detectives using special devices to listen through walls. A few weeks ago, I posted about a Laser Espionage Microphone, and today, I’ll show you how you can make a high-tech spy stethoscope for under $25. All you need is:
- A cheap stethoscope
- A pair of multimedia microphones
- High-Tech Bar Tables Offer Virtual Flirting
- High-Tech Electronic Mouse Traps
- Nine Must-Listen Podcasts For Geeks
- Pontiac G8 GT Spy Hunter-like Commercial
