Re: Auxliiary capping shutter for pinhole camera

[James Schenken <jds@xxxxxxxxxxxxxxx>]

Andy,

Loved your article on how you did it.

Just a couple of questions.

For the drive motor, when you actuate it assuming a clockwise direction, what happens when the control lever is returned to neutral?  Does the motor just stop or does it move counter lockwise?

How much resistance to turning does the motor give when not actuated?

The steering motor can move in both directions?

Did you consider using both motors, one to move the shutter one direction and the other to move it back?  A drive belt would connect the motors so while one is driven, the other is forced in the opposite direction.  This only can work if motors don't automatically "return to zero".

Cheers,

James

Maybe you remember that question about a remote controlled auxiliary shutter for a pinhole camera? Well, I wrote up a little "how to" article relating the obstacles, errors and successes along the way. Critical criteria were that it had to be inexpensive and had to have no physical connection to the camera. This was "customer" imposed. The customer is a good friend of mine so could not "argue" much about alternative solutions. Read about it here:

Suggestions and comments for improvement most appreciated.
