I prototyped everything on a breadboard and it worked under the light of a lamp in my house.<BR/><BR/>Now that I've fully assembled everything, it doesn't work under the lamp. The motor has a high pitched whine and according to the book that means I should use a smaller resistor. So I swapped the 100k resistor for a 1k resistor. The whine is gone, but it still won't run under a lamp.<BR/><BR/>When I take it outside to full sunlight, it comes on and stays on until the solar panel points away from the sun. It doesn't pulse like it did under a lamp when it was all breadboarded together.<BR/><BR/>Fortunately, I bought enough materials (except motors) to build a couple more so I can try again.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-1362650730047230957.post-45512046722965552192008-03-05T17:02:00.000-08:002008-03-05T17:02:00.000-08:00I have a question and you may be able to help. i'...I have a question and you may be able to help. i'm assembling my FLED SE without a solar cell, its in the mail so i'm bench testing with 2 AA batteries. my FLED SE seems to be working, but the LED keeps flashing after the transistors 'switch'. I can remove the LED and the switch stays open. so i know the switch is working. so i'm looking for some clarification about how the LED should function. Should the LED flash at all or only when it activates the 'switch'?Anonymousnoreply@blogger.com
