Bookmarked. That database is pretty impressive. Not too heavy on the BEAM stuff however but there sure is a lot of info there on general hobby electronics....

The FLED SE is a form of the SCR circuit with the positive feedback loop closed through the resistor. The FLED SE is triggered through the FLED which sets the...

Hi Dave, Welcome to BEAM! I'm sure Wilf won't mind, my putting my 2 cents in. As said, the main benefit of the FLED SE is the availibilty of the parts. Like...

Thanks Myc. Even I understood that! If I add another solar cell (5.5V), to my symet will it be more efficient in lower light, or is the lack of interest...

Hi Doug, Adding another solar cell doesn't help the SE's "efficiency" but rather helps "fill" the capacitor bucket (using wilf's water analogy) more quickly. ...
