Inspired by the <a href=\"http:\/\/en.wikipedia.org\/wiki\/Joule_thief\" target=\"_blank\">Joule Thief<\/a>, a simple flashlight circuit that cleverly allows light to be produced from a depleted or &#8220;dead&#8221; AA battery, I wondered if the design could be made <em>even more <\/em>efficient, and <em>even easier<\/em> to build&#8230;perhaps easy enough for a school-age child to build?<\/p>\n<p>I contacted ETOW volunteer engineer, Gregory Majewski, who immediately set to work on the HumanaLight project. His goal: to make a bright, highly-efficient LED flashlight that could be easily built from common, inexpensive electrical parts, and powered by\u00a0either new (or used)\u00a0batteries. And what did this talented engineer\u00a0deliver? <em>The\u00a0HumanaLight.<\/em><\/p>\n<p>Greg&#8217;s HumanaLight design was astonishing: it produced light\u2013<em>continuously,<\/em> meaning, without being turned off at all\u2013for <em>two full weeks<\/em> on a depleted cell. A fresh battery yielded <em>four full weeks<\/em>\u00a0of usable light. The original\u00a0HumanaLight prototype (affectionately known as\u00a0the &#8220;TrashLight&#8221;) could be built on most anything, including scraps\u00a0of wood or plastic. This design, now used in the field,\u00a0requires no soldering whatsoever and can be built almost entirely\u00a0from recycled components. \u00a0Moreover, it can be sold, and the profits reinvested in local schools, health clinics, and other crucial services.<\/p>\n<p>In 2011, I presented this light at the <a title=\"GHTC\" href=\"http:\/\/www.ieeeghtc.org\/\" target=\"_blank\">IEEE&#8217;s inaugural Global Humanitarian Technology conference<\/a>, where it generated much interest.<\/p>\n<h2>The HumanaLight Kit<\/h2>\n<p>This year,\u00a0with the assistance of another volunteer engineer, David Cripe (NM0S), we set about\u00a0the\u00a0creation\u00a0of a simple HumanaLight kit that we can offer for sale\u00a0here in North America, in order to apply the proceeds to ETOW&#8217;s\u00a0mission. \u00a0School children, makers, experimenters, and hobbyists of all stripes will all find this a fun kit to assemble\u2013and a useful light in times of emergencies.<\/p>\n<p><em>Ears To Our World, and those we serve, are very much in debt to our volunteer engineers who made this possible. Many, many thanks to Gregorgy Majewski for developing and designing the original HumanaLight circuit;\u00a0he put many hours into testing this amazingly efficient circuit and bringing it to fruition. We also heartily thank David Cripe (NM0S) for designing the HumanaLight circuit board and kit. \u00a0And\u00a0David&#8217;s design makes this kit affordable and functional, too, in support of the light&#8217;s original purpose.<\/em><\/p>\n<p>If you would like to purchase a HumanaLight kit\u2013and support Ears To Our World\u2013<a title=\"Universal Radio\" href=\"http:\/\/universal-radio.com\/catalog\/misc\/0814.html\" target=\"_blank\">please purchase at Universal Radio<\/a>. \u00a0Thanks!<\/p>\n","protected":false},"excerpt":{"rendered":"<p>If you&#8217;ve been an SWLing Post reader for long, you probably know that I&#8217;m the founder and director of Ears To Our World (ETOW), a charity\u00a0built on the belief\u00a0that\u00a0access to information is access to education.\u00a0And that access is achieved, of course, via radio: \u00a0self-powered radios distributed to schools and communities in remote, impoverished\u00a0regions throughout\u00a0the world.
