My effort to great telecine machine


#1

This is project, witch started due to discovery. I had in our stock several 8 mm films.

I went to our local library , there was suppose to be digitalizing device. Yes, but it worked only for half reel, in a session. And then freezes!

So I decided to do it by my self.

Probably case not well planed, but so does things happened, right?

So I bought two Nema 17 stepper motors, have had 3d printed several parts. Took motors from old scanners and build platform on acrylic plate. Have two Adafruit DC+Stepper Motor HAT mini kits. I

I removed one DC-motor, one is coiling film after stepper motors with low power. It is set so, that it start to slip, if too heavy film tension exist. Poorly technically innovated.

Film reel 1 is set to release film from dummy shaft (stationary), which let reel to slip on it.

Raspberry Pi 3 and raspberry camera V2 are used.

Stepper motors are set to push and pull the film, so that the push is early.

Camera works pretty nicely, and I only pull the lens outward. This was not possibly with camera V1.

So far, I have used only bicycles led light.

So I am now able to take shots frame by frame.

What then?

I have installed OpenCV. Go forward with “face” recognition?

My skills with python, are basically, that I do know, it is not snake.

Now, I do understand, what is the meaning of DIY .

Hello K,
Do you have footage shot with the V2 camera? Can you post a link?

These look great, @K.Tapa! Thanks for sharing your project. Kinograph is based on open-source hardware philosophies. We love it when people share their ideas with us. It’s very helpful and exciting for us to see how you have made your projects, too. Can you post pictures of your machine and any links to documentation (code, sketches, etc)? Thanks!

Matthew

Thank you for your kind words,

I have gain something, but a lot to do still.

Old super 8 mm films are not in very good condition. I am surprise, that I got something out off it with raspberry pi camera V2. No macro, only adjusted camera lens.

I rather not take photo of the device. It is real development platform, in deed.

Acrylic plate, old small wooden legs hanging under it. 2 Nema 17 stepper motors, printer rollers and other thinks from Alexamders Raspberry Pi based 8mm telecine project.

2 Adafruit stepper motor hats 2348, and old technical parts.

Well, Arduino would have been better choice?

My intension’s are to make prober platform, when and how I manage to be satisfied?

So, basically I have done still a lot manually. Learning slowly.

Thank you all, for your support.

To reveal the photo quality, point 62nd parallel north. Winter, not very much light at that time of year in around 1980?

Camera Kodak XL 55?

Raspberry pi V2 camera did pretty good work. Considering, that I have this bicycle constant led light in use. Only the right led pointing to camera.

Nb! my innovation for diffuser, peace of white Cannon copy paper. Pretty good innovation?

When I ordered the 3d parts, I had a feeling, that white color for camera mount should be not good. Other prints are white.
