I've posted several guides on my web site to assist folks who want to work on their own Harmony remote controls. Most have pictures, but some are still long-winded narratives. Eventually, I hope to put up full video instructionals, but for now, there's plenty on the Harmony One/900, 880/890 series. So, please visit and pick up some guides. Always happy to answer any questions as well, though if you have specific questions about device configuration, I'm probably not the best resource for that.

P.S. - I'm also the Ebay guy ;-)
