Jameco Electronics
Jameco Electronics is an electronics parts and tools supplier. It is one of the top three best-known suppliers to electronics engineers, because it has advertised in electronics magazines extensively for more than 30 years (as of 2013-11), and it has a very large, diverse inventory.
It is almost as famous as Digikey and slightly more famous than Mouser Electronics.
Jameco has a "Club Jameco" program in which hobbyists can create kits, and, if they are popular, sell them to other hobbyists. If a kit is chosen, the creator can earn a small royalty on the sales.
