This is a very inexpensive and relatively simple project to do yourself. Buy the kit <a href=\"http:\/\/laserpointerforums.com\/f64\/fs-18650-build-kit-easy-assembly-445nm-blu-ray-red-43857.html\">here<\/a>. The web page is not a stellar example of design, but the video above is easy enough to follow.<\/p>\n<p>Starting with an inexpensive but overbuilt metal flash light, a laser diode and optics are fitted, along with an upgrade to the power supply to source the 1A needed for the diode. The <a href=\"http:\/\/modwerx.com\/shop\/56mm-445nm-1w-laser-diode-p-62.html\">diode<\/a> itself is about $55, the total price is under $200.<\/p>\n<p>It might not be rock stable, but even the $3000 solid state lasers I&#8217;ve used flicker like crazy.
