Here’s a new thread for tracking people/sites/books/whatever that can be useful to us.

First ask: does anyone know a Mechanical Engineer that would be willing to weight in on some of the questions regarding motors? Im continuing to try different setups. My main questions right now are:

  1. What kind of motor is best
  2. How many motors is optimal, and where should the be placed
  3. What feedback is necessary

Right now I’m sticking with steppers, experimenting with 1, 2, and 3 motors in the system, and going with two feedback options: rotary encoders at the reels and a hall-effect sensor for FPS in the film path.

Not using accurate inputs, was more of a test. Seems like something we should try with all the correct figures.

@Maker this looks great. Can you give us a link? Your images only show the root of the URL.

I couldn’t find a direct link. You need to log in as a free member, and then choose an application.

Raspberry Pi gets 8Mpixel camera module
Two camera add-ons for the Raspberry Pi 3 now offer 8megapixel resolution.

An integrated image sensor also enables the computer board to capture 3280 x 2464 pixel static images.
The Raspberry Pi Camera v2 and Raspberry Pi NoIR Camera v2 modules which measure 25mm x 35mm x9mm are available from element14.
The v2 cameras have the same video capability as the original cameras supporting 1080p30, 720p60 and 640x480p90 video, and link to the Raspberry Pi board through a dedicated CSi interface.
The NoIR camera v2 has a No InfraRed (NoIR) filter on the lens which makes it the perfect option for infrared photography and taking pictures in lowlight environments.
The new v2 cameras are backwards compatible with all Raspberry Pi boards and have the same footprint and weight as the previous 5MP cameras.
The Raspberry Pi Camera v2 and Raspberry Pi NoIR Camera v2 are available at the same $25 price through element14.
Likely applications include low-light photography (NoIR Camera), drones, CCTV, weather stations, school projects and more.
Claire Doyle, Global Head of Raspberry Pi at element14 writes:
“The camera modules have been two of our most popular accessories and the upgraded versions will let users capture higher quality images in both day and low-light settings. Whether it’s for CCTV, home automation, weather stations, drones or even sending into space, we’re looking forward to seeing the photographs and videos from the next generation of Raspberry Pi cameras.”

Ah, that’s why I couldn’t find it. Thanks! Will check it out.

This is a good read. Has great charts comparing film scanner models.

Link does not work. Need to sign up and sign in. Just search last part of link.

I signed up and searched for both “Scanner Technologies” and “Michelle Carlos” and got no results. Is there another way of sharing this or downloading and posting elsewhere?

Came across this post, a project based on raspberry pi with a simple transport… https://www.raspberrypi.org/forums/viewtopic.php?f=43&t=79582

Another interesting frame by frame project. http://www.instructables.com/id/28-mm-Digital-Telecine/

Not a telecine project per se, but in my research how to drive bright RGB LEDs I found this excellent electronics tutorial on LEDs:
