How to make a Pull Pin Fuse

Gear & Studio Setup List: https://vonmalegowski.blogspot.com/20... Setting up a reliable perimeter alert system at a campsite or airsoft field usually means buying expensive reusable trip alarms, though a simple spring-loaded trigger mechanism does the same job with basic workshop parts. This video walks through building a disposable pull-ring striker mechanism designed to fire a standard primer or trigger an audible perimeter alert when tripped. Because the design relies on direct spring tension rather than complicated linkages, it stays dependable even in rough conditions, continuing to function in my test even after a section of the housing snapped off. You can easily scale the build with heavier-duty tubing and spring steel for durability, or adapt it for airsoft smoke and sound simulators. Please follow all local laws, fire regulations, and field safety rules when testing or using primer-actuated alert devices, and always wear eye and ear protection.
