Would you happen to have a large supply of pin headers? A project I'm working on requires two 8-pin headers, 1 6-pin header, and one 2-pin header....I'm willing to mail parts to anyone in the USA at no charge if it fits in a standard envelope needing one stamp. I would do this on an as needed basis. If you have a project, post the parts list and those willing can send you what they have on hand. Myself, I have lots of surface mount resistors and caps in 0805 package and general purpose transistors in sot23 package. I also have through hole resistors and 7400 series parts and lots of oddball stuff too. I can't mail a roomfull of stock, but if I provide specific things for a project, it's likely to be easily mailed in the USA.
Also, don't expect express mail service and I can't promise I'll get it in the mail that very day.
