Wow! I had this same idea in the shower yesterday, while just thinking about things. Using an LCD as a stand-in for a slide, and all! I wasn't sure if anyone else had thought of it; seems like I was beaten out by 6 years. Still, I'm glad it exists at all, rather as a dustbunny in the back of my head. This is so cool. Thanks for sharing.

I think that your intro is just the best, please, please, PLEASE! never change it. Cheers

Fun fact about the projector in the video: I found it on Ebay Kleinanzeigen (German version of Craigslist) for 5 €. I went to the house of the owner here in Cologne and upon arrival I noticed a gigantic and incredibly expensive High-End Audio-System in his house. After I had inspected the projector I couldn't help myself and started a friendly conversation about his stereo system. It must have been worth many tens of thousands of Euros if not more and the guy told me that he "worked for a Hifi-magazine" but that it was also "his hobby". So I left and on my way home I checked his name on Google only to find out, that I had just visited Michael Lang, the chief editor of the "Stereo"-magazine, positive-feedback.com/interviews/interview-with-michael-lang-editor-of-stereo-magazine/

Deine Intro Musik ist sehr nostalgisch, gefällt mir! Durch das Intro sehe ich sofort das du ein Fallouter bist.

Hey! Part II to this video is now online: kzfaq.info/get/bejne/rtd0aNyTqru6eKc.html

Keep in mind that heating of the LCD panel will end its lifespan early. TFT technology is more heat resistant than regular LCD panels. I made from scratch a video projector back in 1992 using a CASIO pocket TV but that technology was plain LCD and the screen burned out after a few minutes. Then I acquired the first Phillips TFT TV pocket projector and that ended up being stable. I even sold the projector to a school when they were not yet available in the market...

very nice hack , and very nice proof of concept. The lenses on these projectors can be quite good. My concern though is something that shows to this presentetion and namely the resolution with the overhead projector we utilize a normal tft screen with a resolution of something like 1024x768 or better on 15inches screen. On the wall this translates to a low ratio and a good non pixalated screen. with the dia projector we are constrained to use a 35x24mm window with a resolution of something like 480x270. This creates a huge blow up that shows on the pixelated screen. even by using a 60x60mm forma projector things can not improve much as we will also need a high density lcd screen which is not so easy or cheap to come by. but thanks for one more very nice project.

This is a great channel showing re use of old machines and components. This was a quality antique projector before the failed experiment. It seems now it is only useful for the parts bin. It may have been obvious that a smaller lcd or larger format projector would have produced better results. I would have preferred to see a repair or tune up video of this machine. Maybe an LED upgrade of the light source if possible. Keep up the good work!

Last time I visited a mass in my town they still used this for displaying the lyrics. I think that was around 3 years ago.

I really enjoy your inventiveness :-D, the slide projector is not too far away from commercial units that people use for presentations. That one was built really well, german engineering is well known for quality and reliability. Although they can go a bit too far with complexity, simple is often reliable :-). If you do find a bigger 60 x 60 mm lcd, you may want to add a really good fan near the lcd, i can see it being cooked by the lamp, that would be a shame :-(.

Maybe take a display from a broken mobil phone, maybe with cracked glass, display is often still intact

Interesting that the first concept of a digital projector was a monochrome LCD in a slide projector, the guy that was working on this was at the time trying to work out how to get 3 LCD's in focus at the same time, there were no colour LCD's back then, so the 3 monochrome LCD's would have filters for each colour. That was the last i heard until digital projectors were released. I've done searches, but can't find any reference to it.

Hi, Thanks for sharing your ideas with us. I just love it and also enjoy your German accent.

that's awesome! i have an old slide projector taken apart right next to me. i'm gettin' ideas. thanks! looks like an awesome channel!

It won't necessarily fit the dimensional requirements, but an inexpensive pay-as-you-go phone would probably increase your resolution by quite a bit.

good experiment! using a slide projector was a great idea :D

wow that was amazing and old camera aslo looks preaty good 😍 i love that type old things 😘

The 1.5" screen on the back of my SJ4000 is quite high res, and quite similar to a 35mm slide

I am looking forward for this major upgrade you are talking about :).

Surprised I didn't see mention of using a display for a Raspberry Pi. The most likely candidate I found (assuming I still know how to math) was a 2.8in TFT display which should be a touch smaller than what is ideal. I also found a 3.2in display, which would be a touch big if that were a square, but it has a wider aspect ratio so I doubt that one would work at all.

Maybe get an lcd slightly smaller than the 6x6 size, so that you can block out the edges of the round light, and have the image on the wall be more square?

You make excellent videos!! Thanks to AvE from me, for turning me on to your great channel months ago!

Geilo, davon traeumte ich als Teenager als ich meinen ersten LCD TV hatte, Casio TV-21. Ich dachte schon damals: "koennte man nicht das Display in einen Diaramen bauen, und das ganze dann mit dem Dia-Projektor an die Wand zaubern"? Natuerlich mit einer miserablen Aufloseung, und nur in schwarz weiss, aber die Idee gefiel mir immer. Meinen ersten LCD Projector kaufte ich mir einige Jahre spaeter, Sharp XV 315P, brutal teuer, und genauso schlecht, aber dafuer in Farbe. :-) Danke fuer's Video, aus Kanada....

Tpai, for god sake, never drink a Belgian beer straight from the bottle

you should use a modern smartphone screen with high resolution. Maybe you can get cheap broken glass phone. Just don't know if you will be able to remove the backlight.

The Raspberry Pi GPIO displays that you get from AliExpress should fit , you can connect it to a raspberry pi and install openelec , maybe even retropi for a awesome little media player on the go. the biggest problem will allways be resolution I think the highest I've seen those small screens go is 320x240 you can get higher but they are ofthen times designed for cellphones and can't be driven easily. Regardless, awesome project and video , looking forward to some more experiments.

i took one to school in like 2000 in America to show slides from my dads time in yap during nam

The heat from the bulb will severely shorten the lifetime of the small LCD screen, I would make sure that it has ventilation, and perhaps insulate the electronics from the hot areas. Also, see if a suitably bright LED bulb can replace the projector bulb. However that might not fit the low-cost theme.

A small tablet or smartphone could work. You'd probably be better off gutting the projector and making a custom enclosure with the lens and bulb.. Then you could use an even larger screen by adjusting the focal length between the lens and lcd to suit the width of the LCD.

maybe buld a litel licuid dilspay in form of a slide image that you yust put in to any imgprojector

Maybe one of those cheap rearview LCDs would work? Not sure if the quality would be sufficient though...

I wanted to do this many years ago. I couldn't find a slide projector anywhere at the time so I gave up. Wouldn't you know some one game me a computer projector and sure enough a month later I was seeing slide projectors everywhere on craigslist and thrift stores.

some of the ones used for rearview backup cameras would probably be the best for your project. I'll keep an Amazon link as a reply

I wouldn't keep the original lamp source. Old A/V lamps had to be fan cooled. Not properly cooling them often leads to early failure if not explosion, in my experience.

maybe from an old borescope? i see them sometimes at conrad's returned/defekt section

Hi from Norway

Nokia E6 has a nice 62.5 mm diag 640x480 (326 ppi) screen, no idea how you might drive it though.

Yeah, the problem is that you must have a small screen with high resolution (thus with high dpi). That's hard to find other than custom-made in a production line...

Maybe a cheap Polaroid or Archos phone would do the job ? But very good idea, I will probably try to do this with my French Prestinox Slide projector

I want to be like you when I grow up. And I'm 19.

the pixels are enormous :), what about qhd LCD display, it would fit to 56x56mm hole

I'd consider make use of an old & cheap (nowadays) smartphone - like Samsung Galaxy "Chat" i.e. - Small, but relatively high resolution 4:3 ratio screen and Android (there are also similar older & even cheaper winndows Mobile models) (multiformat media players + SD cards + internet browsing etc.) - That'd be kinda smartprojector!

I bet this guy can make a weapon out of a toaster and a car battery

Awesome idea.

my university still uses these projectors...

Need more megapixels is all, the concept works!!!

One manifing glass before lamp needed

I see that you have a good taste in beers!

Very cool!

can you put some latest mobile's lcd with cropped video ... lcd with better resultion can give a better sharp image ? may be some Iphone 4 (retina display).?

easy to make but can't be full resolution pixels maintained.

when they were trouble shooting it in the place theyanufactured them...

very cool

as always great!

A cheap android -tablet- cellphone would be the best I believe.

Epic win!

what about an "old" GPS display ?

Great job with this channel. However- no soapy water this time ?

Why do so many germans i know speak english with a better vocabulary than me? seriously dude you use words i wish i use everyday.

الله يسلمك

anybody know wat a good LED replacement bulb for ben q mp720???

Slide projector bulbs were/(are?) expensive and short lived.

will it have to be 1970. cant use 1980 1980 1990 2000 2010 2020? diaprojector. if can then topis is incorrect it will work all

belgian beer :-) nice !

Can you help me please, I opened my wonderwall projector to clean it the lenses but it got worse as the picture became not clear at all :( I just cleaned it with glasses clothe cleaner

Use any HD screen of mobile

Hi mate. While I like the project, I found it a bit of a shame that you had to take that very nice projector apart. I realise that it only cost 5 euro, and that it was yours to do with what you wanted, but some things should be saved IMHO. Not many good products are being build anymore.

Not bad for €8 and some duct tape :)

buy an old Beamer with an broken lamp for 5-10€ and use his LCD Panel!

1,000th thumbs up.. lol cool stuff.

Hmmm Pauwels Kwak... Dont drink to much or you'll be Kwak... lol Schol, santé.

Der Arme alte Diaprojektor.

dellite gloves now

👍

Kamera Link?

Eu tenho 2 projetores de slides, 1 é munual e o outro é com controle remoto, mas esta era infelizmente acabou. Rio RJ

can put a sceeen of nokia 5130 good quality

Je suis sur que tu es belge

HAMMER!

are you from belgium? I see that you drink kwak

Hey Ich weiß wo man LCD panels bekommt...............schau mal bei pollin.de vorbei...die hamm sowas verschiedene modelle und ausführungen zB. www.pollin.de/shop/dt/NjA5ODc4OTk-/Bauelemente_Bauteile/Aktive_Bauelemente/Displays/LCD_Grafikmodul_OPTREX_DMF50944NCU_FW_2_320x240.html

Kwak!

u should first finish your unfinished projects..

Why do you lie so much about the pryces ? you can never by a projector for 5 euro ... only the manual costs that much lol !
