14. Inside a Hollowed-Out Old Appliance
Old electronics make great camouflage. Think of that broken microwave in the garage or the dusty printer in the corner of your office—most people wouldn’t even give them a second glance. You can gut these appliances, line the inside with insulation or padding, and tuck a compact safe inside. Be sure to label it with something uninviting like “spare parts” or “dead unit.” It’s an especially good trick for garages, sheds, or laundry rooms where things naturally look messy or out-of-use. As long as the appliance isn’t plugged in or making noise, it’s hiding in plain sight.
