Hi, just wanted to share a little success i had recently.
i've designed and built a transceiver that uses Fire to
signal in Morse Code. The "receiver" part was not sensitive
enough for the show, so whats missing in the video is
the telescopes and light sensors to see and decode.

the transmitter part worked well after some timing tweaking,
turns out Fire has a long decay, and i had to adjust the normal
spacing of 1-3-5-7 into 1-5-9-9 or therabouts. but i think
you can get the idea from this,

comments and/or suggestions on light sensor modules or
other options are appreciated.
i was using an OPT101 (pin diode with integrated opamp)
from TI they sampled for free.
the telescope can succesfully "light up my hand" held in
front of the objective lens, but appears to be a very low energy quantum.
anyways, thanks for looking,
