Welcome to zws.com, the official online presence of Lewin A.R.W. Edwards. If you've arrived here from a search engine, the odds are good that you're looking for someone to help you make a toy, LED or LCD display device, or other electronic widget of some kind. But that's not all I do!

• The capabilities page describes some projects that give you some idea of the things I do.
• Current and older open-source and public-domain projects I've released are available for download at the products page.
• I write technical books about embedded engineering. You'll see Amazon links (thumbnails of the book covers) at the top of every page on zws.com.
• I've written many other published articles (click the link to see my writing portfolio) and am always interested in new writing projects. If you represent an online or paper technical publication, and you're looking for writers, I encourage you to contact me to discuss possibilities.
• And you'll find even more interesting material on my personal site and my computer museum site.
• Last, but not least, here's a little information on the history of zws.com.
