Aah those Over Head Projectors bring back memories. I remember when the teacher used to say. "Go get the OHP" You'd have to go to the AV room and wheel the OHP in on a trolley. Pretty heavy when you're 6 years old!!

Thanks for another great video. I will now keep away from projectors. It's interesting to see just how far we have come in. From big metal boxes to small plastic boxes and not heavy at all.

You can use an old projector if your eyesight is bad, help you read books/newspapers etc. Smaller lenses can be used to create Projection TV's out of portables/ipads. Set inside a tube they can also be used to make underwater scopes for metal detecting or river fishing. Campers might use lenses to focus sunlight to heat rocks...or for matchless firelighting.

one of the 1st items I picked up was an old 80's model protector. Been storing it ever since, thinking it might be worth something. Most likely not to much.

if you open a projector and the circuit board has 3 little ribbon cables around the center of the board, its basically garbage, appart from the main board

How do you do it! Every time I pick up something new and have no clue about it, you produce a video! It is a HUGE help for me, but I am going to search for hidden cameras :-)

What do you do with all the plastic that is accumulated from all scrapping of projectors and such?

Good video and as always pretty well detailed and in dept. In the first digital projector that you opened up, is that good plating on the side where that metal shield piece was screwed on? It's almost looks copper color. Sometimes I can't tell if it's gold plating on the board or something else. .. Is it usually always good if there's plating on the top of boards? Or does it depend and/or can it be something else? Thanks

How about the ribbon wire in those digital projectors, are they silver instead of gold?

Ahh, I always thought they were silver if they weren't gold. Good thing I never wasted time on the silver colored ribbon wire

good video, but could you take apart at least one small digital projector in full? I'd like to see what the lens mechanism has inside, as well as the rest of the unit. Not too satisfied with the video.

+The E- Scrap Man the lens mechanism is just a series of lenses, there's nothing in it to show
