I recently volunteered to teach an Electronics merit badge class for Boy Scouts in my area. I tried to anticipate challenges that might arise when describing small components like resistors and capacitors to a large group, or demonstrating how to use a soldering iron.
That made me think of a 37″ LCD TV that a friend gave me a few months ago when I was scrounging for “used electronic devices”.
They said that it tended to go haywire in the middle of movies, etc. Without even testing it, I had left it out on my (covered) deck where it acquired a nice coat of dust … but now I wondered if it might work well enough to serve as a poor man’s projection screen.
