For a few years now, I’ve had this hare-brained idea to try to separate the layers of polarizing film from a scrap LCD panel and make a polariscope out of them. So whenever I come across a dead one I tear it apart and do some experimenting. Probably been into half a dozen by now. But I’ve probably learned as much, or more, about how they actually work by watching Bill Hammack’s video this week. As always, Bill’s work has something to offer novices, experts, and those, like myself, who know just enough to be dangerous. [Thanks, Bill!]

    That was wonderful. It’s just amazing what these videos manage to pack into such a short run time. Clearly some excellent script editing, (and reading!) Thank you for these!

    I am an artis and do not have a background in this but I recently acquired an old, broken, sampo monitor and took it apart and wondered what all these parts do. You cleared up some of my questions but now I’m wondering what can these parts be used for before I alter them and ruin something that can be recycled into other than art. I went to Sampo’s site and there are no schematics giving info that I could use as referance.
