Back in 2009, I needed some bend sensors for a sign language translation glove I was making for fun, and the commercial ones that just came out were over my budget considering I needed at least 10.
Then I came across plusea’s DIY bend sensors on Instructables.
It was what I was looking for but I had one small problem. Well, a few problems actually. (Not with the ‘ible of course)
All the different instructables required the use of neoprene, or at least conductive thread and conductive fabric.
I could get the anti static bags locally, but getting the above items would mean the total bill (after shipping and currency exchange rates and tax) would consist of mostly that, and not the cost of the items.
