Another DIY film scanner

For anybody interested in the film scanning/digitizing aspects of my Cable Car Super8 film, here's a little sneaky peek behind the scenes...

Yes, this really is my home-made 8mm film scanner project in all it's current glory.

There are two 20 tooth sprocket wheels which drive the film along (each one has a stepper motor underneath) and a third stepper to turn the take-up spool. All the stepper motors are running together under control of the Stepper Bee card. The machine vision camera you see is the Sumix 150M.

The light source is 10 rectangular white LEDS with a small piece of opal glass diffuser in front of them.

The 2 sprocket wheels, the 4 pulley wheels, and the film gate are all pieces I've designed in 123D Design and had 3D printed at Shapeways.com.

The camera sits on a Manfrotto plate and there are crude wooden guides for sliding the camera backwards and forward and sliding the main deck from side to side. I pack layers of card under the deck to achieve the correct height. So this is not exactly precision engineering...

Although I've been fooling around with this for quite a long time now, there's still a long way for this to go... Did I mention there is no automation of the scanning yet and that the camera only captures in monochrome? The registration is not great either, but I'm using the Stabilizer in After Effects and getting passable results that way.

I've ordered some more bits from Shapeways so no doubt I will soon be tearing this one apart and starting again...

Cable Car : A new super8 film

Cable Car : super8 film, DIY processed & digitized from Chris Gavin on Vimeo.

Well here's my latest short cine film. It's very much DIY movie-making this one; shot on Black & White negative super8 film, developed in my home-made spiral processing tank and DIY digitized (using a home-made contraption) too. I hope soon to write a bit more about this.

Fun with Processing #001: Particle experiments.

I've been dabbling a bit with Processing lately. Processing is a free development environment, offering all kind of potential for geeky visualization and interactivity projects.

I've been working my way through the tutorials and here's one of the first 'sketches' I've devised.

This is NOT an embedded movie... I've written this visualization in Processing code. This is basically a bit of generative art that is served up to the viewer; there are some randomized variables so this will be a little bit different each time it's viewed. I've just added a little interactive feature too, so try clicking on the particle cloud and see what happens!

It's early days for me with this, but I want to find out how one can embed such a creation into a web page or blog like this, if you can see what I'm talking about below, then I guess it's worked...
