I've been hunting around for info on the ribbon
what I've been able to find about the resistance is:
0.6 x 0.10mm - 24,5 ohm/m
0.5 x 0.10mm - 29,4 ohm/m
0.4 x 0.01mm - 43ohm/m
0.3 x 0.10mm - 48,9 ohm/m
The best comparisons I can find are
0.2mm kanthal a1 wire is about 43 ohm/m
0.25mm kanthal wire is about 29.3 ohm/m
so as near as I can tell:
0.5 x 0.1 ribbon is the same as 0.25mm wire
0.4 x 0.1 ribbon is the same as 0.2mm wire
has anyone else found out anything different?
Based on this, I'm trying to get 0.4mm but the only place I can see at the moment is on ebay, a seller in Denmark - but it's not cheap that way.
I hope the mesh company get it in - their 0.5 ribbon is a very good price
very good! £3.75 (£3 until end of march) + P&P for 10 metres
