http://www.coilgun.info/about/home.htm Learn about coilgun design. These web pages describe theory, design and implementation. We have several single-stage coilguns for testing ideas about efficiency and performance. http://www.coilgun.info/about/wa7kvc.htm http://www.coilgun.info/2010-08-28 Sat, 28 Aug 2010 19:58:00 PST I'm on the air again! My station is working great now that I've setup my Kenwood TS-850s at home and my Kenwood DM-710a vhf/uhf in my car. Here is a web page about my ham radio station WA7KVC. http://www.coilgun.info/lev_popelex1996/home.htm http://www.coilgun.info/2010-01-22 Mon, 25 Jan 2010 05:05:00 PST January 25, 2010 - Added entire chapter of a levitator article from Popular Electronics May 1996 by generous permission of the author, James Cicon. http://www.coilgun.info/northrup/home.htm http://www.coilgun.info/2009-02-26 Thu, 26 Feb 2009 21:40:00 PST February 26, 2009 - Added entire chapter on AC Linear Induction Motor coilguns, written by EF Northrup in 1937. Lots of good design information and pictures are republished from his speculative fiction "Zero to Eighty". http://www.coilgun.info/mark5/home.htm http://www.coilgun.info/2009-01-25 Sun, 25 Jan 2009 26:45:00 PST January 25, 2009 - Initial assembly of the Mark 5 Coilgun is coming along. The copper wedge contactor is ready for bounce/settling tests and the capacitor bank is reformed and ready for busbars. There's a long way to go yet, but it seemed interesting to share the design direction with you. http://www.coilgun.info/kitt_car/pcb_procedure.htm http://www.coilgun.info/2008-12-17 Wed, 17 Dec 2008 06:09:00 PST December 17, 2008 - I've been making copper PCB (printed circuit boards) to simplify construction. Tom Gootee has thorough notes about iron-on photo transfer using laser printers. This works great! His pages are a bit hard to follow, so I reorganized and rewrote it for improved readability, and to document my own technique. http://www.coilgun.info/about/home.htm http://www.coilgun.info/2008-06-16 Sun, 06 Jul 2008 08:00:00 PST July 6, 2008 - Added RSS Feed to help you stay current with new material added or changed. I hope it helps! Let me know if you like it, or if you have RSS suggestions for me. http://www.coilgun.info/about/home.htm http://www.coilgun.info/2008-06-13 Fri, 13 Jun 2008 08:00:00 PST June 13, 2008 - Completely restyled my entire web site in a gold theme. Replaced all Javascript navigation with PHP server-side generated links. New navigation with three levels (section, chapter, page) makes it easier to find topics. Stored all files in templates for Adobe Dreamweaver CS3 to greatly simplify future updates. Added file version control using Other than that, nothing changed! http://www.coilgun.info/impedance/home.htm http://www.coilgun.info/2008-06-10 Tue, 10 Jun 2008 08:00:00 PST June 10, 2008 - Added the Low Cost Impedance Analyzer article reprint with the author's permission. This is one of many great projects you can find in Nuts & Volts magazine. See the March 2008 issue for a complete coilgun project.
