Yup.
You can
buy the origional wire and wick from the vendors or you can go to what I am guessing is the source. Imeo linked it in the origional iAtty
thread and I am guessing it is still where he is getting his wire just slightly different guages now. I still use this company's wire and love it.
NR wire is .2mm Nickel wire 50g about 178 meters at 14.30
wires.co.uk : Bare Nickel Wire
Resistance wire is .15mm Nichrome 50 grams about 340 meters for about 12.10
wires.co.uk : Bare Nickel Chrome / Nichrome Section
these prices are pounds but you can coop it if you want (I did this with origional iAtty supplies just bought them and split it up between myself and 3 other members.) Or you can
buy it and have enough wire for half an eternity.
They also have .132mm Nichrome for R wire if you want to go higher ohms and it is available in as little as 10 meters if you want to try it. This would be between 35 and 36 awg for us US folks.
