After days of rain and overcast skies, the weather finally broke today. One would think that I’d have spent the day outdoors enjoying the sunshine. Instead, I used the holiday to catch up on a number of small projects around the house, researching the latest developments in flashlight technology and preparing a couple of my power tools for sale on Craig’s list. The kids (and Jeanine) think I am crazy to spend hours upon hours contemplating a relatively small purchase. What they fail to appreciate is that I am learning a great deal in so doing. In this case, I am now up to speed on the latest developments in LED and lithium battery technology, both extremely relevant to the work I do at iRobot.
