pico prototyping

Prototyped the 9 to 11k white LED. Found the forward voltage more than 1 and less than 3. As I suspected. Probably 2.5. Rob "linear1" Arnold recommended a 330 ohm resistor if driving from a 9v source; I found a 470 on the parts bin. Nice and bright!

Helping Hands hand-held a fiber. This might work.
