Hack-A-Day has an article today about using a laser for data transmission. This reminded me of a discussion I had with Mike KL7R about similar systems. My son Billy and I built a very simple version in London in 2007. Check out the podcast above. Scroll foward to 19 minutes 15 seconds and you will hear how we did this.
This was Mike's last podcast. He was killed in a car accident in Hawaii about 10 days later. RIP Mike. 73 OM.
