@Chris: First off, a very good resource I will keep this handy
You would think though that the PSU would just limit the current and not shut off, the little power adapter 5v 1 amp still works it just limits the current i'm assuming?
I actually got a six inch piece of the 24 gauge wire, with electrical tape around it, and wrapped it around a paper clip, I used that small 5v 1 amp power supply/adapter
I can pick up a piece of metal about the size I need from about 1/10 of a mm away, this is not that far however, in this case, Its close enough, i'm thinking the electrical tape is pretty thick, so if I can figure out some other type of insulation, then I might get even more strength out of the coil, that or just get some magnet wire which I eventually will do.
I could also find some sort of iron core, instead of a paper clip, that would help with the strength.
Again I know 1/10 of a mm sounds crazy but its just about right.
I now just have cut the weight of the tiny valve I have in half. Time to get out the magnifying glass
