I am a poor student, was wondering if anyone has any home-brew recipes for making conductive thread for use in wearable electronics?
Well you could use some really low gauge wire, but I can't imagine that would save you any money.
150 yards of conductive thread is only $20 at sparkfun.
Instructables has a post on how to create conductive thread using very fine wire and thread, that combined together to create a strong, low resistance thread.
The principle idea is that you spin the the thread and the fibre together. As Andrew Parnell said, 150 yards of conductive thread is only $20 at sparkfun.
Step 1: Find a conductive sheep or conductive cotton plant
Step 2: Extract the fibers from said conductive fiber source
Step 3: Spin conductive fibers into conductive thread
while it's not so much about making conductive thread, here is a good post talking about the different types of commercially available conductive thread. Gives a good run down of various comparisons, where to buy and what they cost. hope this helps! http://www.fashioningtech.com/page/conductive-thread
