Project Title Need an Electronics Engineer to Build a Safe Burning Wire Demonstration Prototype Project Description I am looking for an experienced electronics engineer to design and build a safe demonstration prototype that simulates an overheated electrical wire. The prototype is for demonstration purposes only and should allow people to experience the characteristic burning smell produced when a wire overheats. The system should use a small replaceable wire that intentionally burns during each demonstration. After it burns, the wire should be easy to replace for the next demonstration. Working Principle Press the START push button. The system supplies power to a small replaceable demonstration wire. The wire heats rapidly and burns in a controlled manner, producing a small amount of smoke and a burning smell. The demonstration takes place inside a transparent acrylic enclosure. After a few seconds, the system automatically switches OFF. Once cooled, the burnt wire can be removed and replaced with a new wire for the next demonstration. Required Features Start push button Transparent acrylic enclosure Small replaceable sacrificial wire that burns during each demonstration Easy wire replacement without special tools Timer-controlled operation Automatic power OFF after the demonstration Power ON indicator LED Strong, stable construction suitable for repeated demonstrations Safety Requirements The engineer should design the prototype with safety as the highest priority. The prototype should include: Fully enclosed transparent acrylic chamber Heat-resistant internal mounting Automatic shut-off after each demonstration Fuse or over-current protection Emergency stop button No exposed live electrical parts Replaceable burnt wire holder Stable base and secure wire terminals Suitable ventilation after the demonstration before opening the enclosure Deliverables Fully working prototype Circuit diagram Component list (BOM) Assembly documentation Demonstration video Instructions for replacing the burnt wire
