The interesting thing about the CD is that while it appears to be a flat surface in fact it is designed to allow a laser beam to penetrate it and operate on the inside of the disk creating pits and lands.
colbec: If this is right then you should get different reception from a CD with Bach's Cantatas written on it than Beatles.
Wow laserdics, I haven't seen any of those since about '86 or '87! I think you could get a 2 hour movie one them, but they would stop after about an hour and you had to flip them over like a LP to get the second side to play. In highschool a girl I dated for a short while had a father that had a collection of about 1000- 1500 of them. Her father was a real movie buff and only bought them, never rented movies.
They did have a lot better picure quality than a VHS tape did, but I guess the reason they failed was people wanted to watch an entire movie with out geting out of there chair to flip them over. At the time they had about or slightly better quality than a BETA tape, but the inconvenience killed them, the same as the BETA's sligthty less play time than a VHS killed the BETA. Add in that they were play only, while both VHS and BETA could record, well you know the rest of the story.
Mayby you could cut one up and try to make a fresnel lens dish out of one! That should work better than a flat platter would. Or you could just save the disc to wacth it again in glorious SDTV, without the low res digital SD crap we can now only get on digital!![]()
I have about 40 laserdiscs..... I remember buying the StarWars triliogy for $399.00, and most others for $50.00-$100.00ea......
Just hearing "For Your Eyes Only" in Dolby surround was remarkable. I ended up buying the little Amgstrum speakers (4 of them) due to that movie. Still use them today...........
Neat stuff.
When I was younger I was able to catch C Band signals bounching off a chicken wire fence.![]()
I saw this in a Popular Science or Popular Mechanics magazine in the early 80's. You could build a wooden frame (about 12' square) and then cover with chicken wire to receive C band signals. I was going to build one myself, but later purchased a 10.5' Luxor satellite dish instead once prices began to drop.
Probably something similar to the pic in post 148 in this thread - http://www.satelliteguys.us/fta-shack/131140-pics-dish-farm-post-yours-too-8.htmlI saw this in a Popular Science or Popular Mechanics magazine in the early 80's.
