It doesnt mean that I wont check stuff regulary to see if there is something new. I found something I like to share with all the reprappers around here. Its called "wire glue", and its on sale on amazon and thinkgeek. It comes in small bottles, but I am sure it can also put in syringes. Maybe a good alternative to solder?
I am not sure about the conductivity, but they say it can be used instead of solder, and the conductivity is pretty good. Who knows what comes next?
