Title: Nifty USB LED light
Post by: isonno on July 07, 2015, 07:31:52 am


One of the hit discoveries of Hacker Camp 5 were these little USB lights.  Plugs in either way, and you turn on/off/dim by touching the back.  Turns out the show is run by a chip called the Sigma SGL8022W (http://http://www.datasheet-pdf.com/datasheet-html/S/G/L/SGL8022W_SiGmaMicro.pdf.html).  The datasheet has the schematic.
