Obtaining non commercially available parts? Answered
For a lot of projects I find myself needing parts that can't really be bought in a store. My latest project requires transparent conductive ink (http://www.conductivecompounds.com/sitemap/clear-conductive-inks.html). Has anyone had success obtaining parts directly from companies like this? I was thinking emailing the sales rep, saying I'm working on a prototype, and requesting a sample. Do you think that would work? Could someone point me toward a template for an email that would sound "professional"? Also what type of payment do you think they would expect, would just a credit card number be fine?
