I’m building a little electronically operated release mechanism. I’ve been designing around mini-solenoids but they are unreliable. I had the idea that I could perhaps effect a release by shorting a piece of fuse wire, causing it to blow and release a mechanism. I only have 24v and whatever amperage I can get out of a moderately small capacitor to achieve this. The lightest guage “off the shelf” fuse wire I can find is designed for domestic applications and is about 6A or higher which is a bit much for the current capacity of my circuitry. I was hoping that could find something that would blow at 1A or preferably even less (200mA would be excellent but probably impossible). I had the idea of breaking apart a 500mA fuse and using the wire out of that, but it’s so fine you can barely see it, let alone work with it, and this only gives you an inch long piece of wire which is a recipe for fiddly frustration.
What could I obtain that would work as very light gauge fuse wire?
