Last thing to fix before getting on and shooting tests is the take up power suplies for the 120V/AC motors. Budget restraint means I’m using cheap electronic transformer/variac but it seems to work. Ideally I’d like to design somekind of clockwork mech for the mag film tensions because its hard to make this camera portable with a 120 volt supply. …

Finally fitted this nice perspex door for the projector head on the printer. Will keep things nice and clean and protected over the coming busy months.

Platter cinema system tables are big pieces of aluminium with curved sides mounted on rigid spokes and a decent bearing. I’ve had them kicking around for years and they started forming ideas when I was thinking about how to employ them creatively. So I’ve got around to mouting a vertical one against black. Next will be some maths and geometry …

An oxberry optical printer and rostrum stand often use very similar cameras infact there is very little difference between them.                     An optical printer images the target upside down in the gate so you thread it in the projector the right way up. This helps you see what you are shooting. …

This is hopefully the last time I post anything specifically about these motors and their applications. I thought, seeing as all the main functions are working that I’d draw up a plan for the whole system so that anyone can use it for themselves. My application is simple. I want to drive ths camera with a motor that lets me …

Most of the cameras I use (and projectors for that matter) are driven by a motor where one full turn, or 360 degrees equals one frame of film (they are all optical printer or animation cameras). There obviously needs to be position accuracy because the camera needs to be closed when the motor has spun 360 degrees, made its exposure …

To get this camera working I’ve managed to hook up another Oxberry part, actually a 2 speed projector drive, seen below. The motor runs on 115v ac and the solenoid fires at around 36vdc. When the solenoid fires it allows a clutch plate to slip thus engaging with the driven gear shaft and momentarily (ie 1 frame) turning the camera …

Well, cabin in the corner of the garden anyway. Trying to crack on with this so that anyone who wants to come and work at Asylum or my studio can stay here. Anyone who doesn’t want to work here can stay as well because that is what friends are for. It will have double bed, woodstove, a fax line, morse …
