• Optical communication using LEDs alone (hackaday.com):

  Slightly defensive comment by Paul Dietz about MERL’s groundbreaking 02002 research on #communication with visible #LEDs, mentioning “some clever tricks to precharge the LED to close to threshold using an additional resistor [which] let us do really fast measurements, even in low light.”
