Optical Communications

It is some years (before my stroke in 2013) that I last tried seriously with optical communications using red LEDs that I bought at low cost via eBay. These days, I expect a google will bring up lots of links. This is a fun branch of our hobby, with very low costs and lots of homebrewing. This is a branch of the hobby I'd like to try again. There is much to learn.
