One of the favourite things to do before the teacher came to do the presentation was to fiddle with the focus and lens position knobs on the projector. They would then spend the next 5 to 10 minutes trying to fix this whilst everyone had a good laugh and time to chat. Bless you class clowns for keeping school fun.

Thanks! I was trying to find a picture or video to show my kids. I realized no one uses these, but they were the best! The worst thing that happened was the darn bulb always going out. I remember my teacher always wanted these specific wipes. And when you got her new pens - it made her day ;) So exciting to be the one picked to haul the cart to another room. LoL. Technology sure has changed.

Last time I saw one of these was back in 2006, and I was in elementary school then.

Last time I used these regularly was in the mid-90's. I was just cleaning out some files and found some from old presentations. True overhead projector story: A professor had set up an overhead slide on a projector and then walked up to the screen to point something out. While gesticulating at the screen he stopped suddenly, then started sneaking up to a massive fly he saw on the movie screen and then suddenly flicked it, trying to get it off the screen. What we realized, and he didn't, was that the fly wasn't on the screen but had landed on the Fresnel lens and was being magnified and projected on the screen, along with the slide. The fly actually came through quite clearly - clearly enough to fool the prof about its location.

One time (in either 2012 or 2013) our teacher told us that she would have let us do PowerPoints for a project but her computer was slow and the formatting didn’t always work correctly. She still had an old overhead projector (though sometimes you had to thump it to get it working) so I came up with the idea of doing what I called “an old fashioned PowerPoint” (looking back now I had some more advanced technology to hand to make it happen) I went down to the local office supply store and purchased inkjet transparencies (the woman at the store was very surprised and said I was the youngest customer to ever buy them). I then made some “slides” in Microsoft Paint (I didn’t have access to Microsoft PowerPoint on the computer I was using and wasn’t fully aware of alternatives at the time). I printed them in full colour and brought the box of printed transparencies to school. I don’t know if the teacher knew what to make of it but she did say as she put it down on the glass that they were the nicest transparencies she’d ever seen. Can’t remember what mark I got on the assignment but if I recall it was quite high. I still have them in there box so technically in the unlikely event if I ever need to do another project about sea scallops (I think that was the topic I was given) and have an overhead projector I can reuse them. ;-)

Honestly, in a teaching environment where you're constantly taking questions and having to come up with new examples on the fly, I'd say these are more useful than a Power Point presentation. As long as you don't NEED super detailed illustrations or video.

These are still used in schools here in Germany. Last year i was on my last year in a school comparable to a „high school“ and these where still used by some teachers.

These were still used when I was in Elementary school in the mid-to-late 90s.

Your childhood belongs in a museum!

It's still in my college 😭😭

To be honest, I LIKE THIS.

Man he make me feel archaic we had these in middle school in the late 90's. Never thought they were that bad.

These were one step above the chalk board when I was in school...Back when a TI-83 seemed like ahead of its time with a game like "Drug Wars"

Haven't seen one of those working since high school. And that wasn't long ago at all. Didn't know PowerPoint started off by actually printing to OHTs. It's obvious now that it's mentioned, just never made the connection.

Thanks for this video able to show my daughter what we used in class. She always talking about her Promethean Board.

Feels like my whole operating system on my cellphone...a projector sheet..but few to nobody else sees it.

One comment about color slides: You could prepare them on a computer using a pen plotter. Canon had a color inkjet printer in 1983, but I don't know if it would print properly on transparency film. The presenter did a great job of demonstrating the traditional overhead projector! I had forgotten about the sheet to cover later points technique, even though I saw it used every day in high school. I also remember when the instructor would inkjet print a bunch of pictures on one transparency film (color was expensive!), then pull the projector back from the screen to make the images big.

I always wondered what model mine is because I was given it as a gift from my art teacher in 2003 for exhibiting non traditional use for murals. I will have to upload a video of it, I believe it is probably from 1984. It looks exactly like the model 9100. The big bulb, the fan, the same exact aperture. I used it to create mural's! Celophane sheets and a lot of patience.

The ending was my favorite bit, I was cackling

At Bell we had "Viewgraphs". You printed on a transparency and put it in a paper frame, then stuck it on the projector.

We still use these in my high school.

Do we have a low temperature replacement for the old projector bulbs? Low or lower?

Last time I saw one of those that I can remember was in 1993 when I was in 6th grade. I’m sure I saw them in high school but I don’t remember. The reason I remember elementary overhead projectors is because my teacher had a short fuse and would slam her hand on it and the bulb would turn off.

This took me back!

The last time I saw an overhead projector used in person was 2011, in my arts class in primary school. Our teacher was trying to make us learn the lyrics for some song that I don't know the name of, and I remember one time she got pissed and switched the projector off because she was getting annoyed that some kids were mispronouncing a word, even after our teacher had told them the correct pronunciation.

the mirror of my overhead projector is broken, and I was wondering if I replace it with a mirror from the store would it still work?

It seems my younger kid's school found some old projectors like this, because they used it the kids (he is 3) for a show and tell project, where the kids would put some toy for the shadow to be projected.

Well I feel old.

Can I use a screen capture of this video if I mention the CHM and the presenters name? Thanks!

90s babies where u at

2004. Page 13 Over Head Projector What is flannel board ?

can you make the student's book's imagines on the wall?

I remember my father and his business partner always have acetate films that work as a slide. Now they have Ipads, just cool how technology changed

Thank u so much sir...It is really very helpful

I remember these at school and church.

There was one of these in my elementary school in 2010.

Gracias por la exposición

ah, OHP bring back my memories during elementary and middle school during late 80's and early 90's

Yeah im this many years old

Mid 80s my elementary school had em. But many of the teachers mainly stuck to chalk and board

Sir is this device an electronic device or not?

never had a chance to see them.

Before beamers became affordable I used a transparent TFT screen on an overhead projector.

There was a liquid Crystal device that you can lay over the screen and Project a Apple [] Monitor screen in real time.

miss using this

So it means we can't use writing papersheets. so bad.

how to write 7 words on transparency sheet

Nice sir

he didn't mention the part where these things were absolutely filled with dust and never cleaned

These would still be great with the only change being an LED light source.

Omg the golden years lol

the last one i saw was back in 2010 when i was in 5th grade ❤️🥺

Alltag in Deutschland :)

Communicator's pledge of allegiance to prosper

We forget the realy first one the blackboard :-)

They Used To Use This Overhead Projector To The Church i Used To Go To.

My childhood lol

So in Germany every school still uses some of them. They always overheat after 10-15 minutes.

Has anyone seen one since 2007 in a School?

was this bad for the eyes of the instructor as they had to actually look into this bright light?

I have a overhead projector. I am sale this item. It is fresh condition and running now.

This is what they had when i went to school, no answering machines, no pagers, no cell phones, no cable TV, no internet. Life was a lot cheaper, and if you called someone, and they did not answer the phone, then you waited and tried again.. All film was Kodak or Polaroid. Could find coke bottles on the street and get 5 cents. Comics were 12 cents, candy was a 5 cents. Gay was against the law. Teachers could hit your hands with rulers. Toys were from Japan. Most cars were made in USA. Everyone was working, plenty of jobs for teens. The world has gone mad since then... Life was good and simpler. Now the news sucks, politics is insanity.. Man i miss the good old days. That was before government mass transit. (greyhound back then) traffic was light (no traffic jams). New cars and trucks were about 3 to 6k. I remember the bank paid 6 percent on savings. Now we are in a debt society and they keep the interest rates low so you will borrow money instead of paying cash... Bought a house in silicon valley in 1977 (san jose CA for 33,000. Two bed apartments were about 180.00 per month. You could only buy a house if you could pay for it from one weeks salary... Bank rules... No police radar, no street light on weight sensors. Another world. It may sound boring but it was not,,, strrets were safe, kids played in parks, no parents drove there kids to school because it was safe.....

I graduated high school in 2010 and they were around, poor Deep South public school

Speking Telugu plz

عندي مثلها للبيع❤
