Lego Technic Super 8 movie projector

lego_super_8

It always blows our mind to see the things that people dream up when playing with Lego. Given enough time, you could likely replicate almost any mechanical device with the right amount and type of blocks.

[Friedemann Wachsmuth] recently wrapped up construction on a very impressive Super-8 movie projector with the help of his friend [Kalle]. The projector is fully functional, and is made completely from Lego aside from the reel spindles, the lens, and the lamp. As you can see in the video below the projector plays the film quite well, and even though it is only lit using an LED flashlight, it’s more than bright enough to get the job done.

The projector boasts automatic film feeding, a 24 fps framerate, as well as fast rewind capabilities – all provided by just two small Lego Technic motors.

You really need to watch the video to appreciate how much work went into this projector – it’s amazing.

    wow … is all I can say.

  2. zool says:

    cool but i can’t imagine you could run it for too long before some of the legos start to melt from the heat of the lamp

    @zool

    Run from an LED flashlight

    Amazing construction!

    @zool: really? A little LED flashlight is going to melt the blocks? I doubt it.

  5. zool says:

    hmm i skipped to the vid and it just said lamp, so i didn’t realize it was just an led flashlight

    I love lamp.

    @zool a LED flashlight is being used as the light source. Id like to have seen more details on the shutter, and how it all was put in, and kept in sync. A interesting project in the end.

    nice build.

    You mean projector, not camera, right? :)

    I have no idea what you are talking about…

    I must have missed that one. I see this projector, my brain thinks camera…I have no idea why.

    This has advantages over a real super-8 projector, the LED won’t melt your film if it gets stuck, and you can rebuild it to take 16mm or 35mm. But if you want to really impress us make an IMAX projector out of lego! :)

    @hirudinea i thik thats not to do the film is to big and must be compleet flat on a big licht to maak a big picture i think you set your house o fire from the heat or you get blind i see it 1 time on discovery how imax work the amezing part of the projector the lens off the projector is a smole 1.5cm bol lens to make the big halfround picture

    The neat thing about using an LED for the lamp is that you won’t burn through the film if your film stops moving.

    Really, really nice homage to what now basically amounts to ancient tech. Extra props for making your own claw.

    About that melting thing – what exactly have you people been using, celluloid film or what? I never had a problem with film melting (sure, I’m not leaving it to just sit there all day if it stops, duh…) Now, film _tearing_ is a whole different beast, that used to happen all the time; you needed a gluing bench if you ever wanted to use the projector…

    If I had the parts I’d build this, it looks simple enough.

    Not many lego projects appeal to me, but this is just awesome.

  16. Generic Hackaday Fan says:

    The video was as impressive IMO. Great job on both!

    Anyone who wants to learn more about how projectors actually work, here is a great explanation – http://www.movingimage.us/sprockets/filmproj.swf
