The Design
You can place this little machine in your radio workshop when you sleep at night. When some evils want to steal your radios, you will be awakened by a loud noise. It detects by the reflection of sound waves (so it won't work on the Moon or on Mars) and they aren't even ultrasonic. During operation, you can hear soft clicking sounds.
