Three random links from my pile of “links to post one of these days.”
- HP Archive. This site is run by Glenn Robb, an Electrical Engineer and HP aficionado. It’s goal is to help others collect, preserve and enjoy vintage HP equipment and literature. By making hard-to-find documentation easily available to all, it is hoped that others will begin collecting HP, and help preserve the shrinking supply of vintage materials. This site will serve to organize a community of collectors, experts and gather volunteers to work together towards a common goal of preservation.
- Simple CPO. Build this simple code practice oscillator (CPO) in an Altoids tin. The straight key is mounted on the lid.
- Surface-Mount Kits. Nightfire Electronics offers a number of different kits and prototyping boards for surface mount circuits.
