I scrounged a bunch of small solar cells from some KMart variety lawn lights and am hoping to make a panda sun tracker with the Connect sheild and a couple of small servos. If I’ve done the math right, I think I can post the data online with pure (bright) sun power. A 2 cell LiPo and the roughly 8v trickle the from the solar cells hopefuly will do the trick. The idea would be to have the FEZ ‘hunt’ for the max output from the panels on a fairly frequent schedule, remembering the results.
Done something (even vaguely) like this before? If so, let me know!
